Alright, my truck stalled on Monday. Tuesday as the wife is driving, the CE light came on. Codes P0306 (Cylinder 6 Misfire) an P1316 I believe. Well the truck has been running fine but I'm nervous about my 99 D1 with 86K. Now I have some SEAFOAM that I am willing to try but am unsure as to how to get this into the intake. I don't want to end up putting it in the wrong area. I've heard tell of people letting it get sucked into the intake, letting it stall, letting it sit 5 mins, then starting it up and watching the smoke screen appear. I just need to know exactly how they let this beast suck it in. I don't want to ruin the MAF or other sensors. Thanks. Any other advice is also greatly appreciated. BTW - I did pop out the stepper motor and clean that thing (wasn't bad as I cleaned it last summer) | ||

Update - CE light went out. This happened after I had to push my disco a little hard to avoid an idiot. Strange but I know a problem still exists. | ||

Have used seafoam, and it's good, I disconnected the oil breather from the intake on the right side of the engine, this is far away from the MAF, and used another piece of tubing to dribble it down! The first time i used it, 60k or so, it was a very smokey start, but now as i use it about every 15k miles, i get very little smoke, Good luck! | ||

I use the valve treatment, and just pour a can of it in my tank. Run it hard (get the RPM's up to 4K and keep 'em there for a few minutes while driving), and it has always cleaned out the carbon from around the valve stems. Usually lasts for about 6 months or so, but I also do alot of around town driving. | ||

We use it in the fuel every 15k service, and, on new to us, highrer mileage vehicles, especially with bad thermostats, in the oil. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 114 Registered: 05-2003 |
Is the hose you are talking about the one that is next to the oil cap and goes up to the intake next to the IACV? | ||

Good question Kevin, and you got a positive answer from 3 heavy hitters on this board who know whatt they're talking about. I've been wondering about that myself, so I just got a memory jog to do it. 110k miles on a d1 that gets driven hard and put away wet. | ||

I just did it yesterday. The line I spray it into is the one on the right side of the engine, kindof at the back. It is the hose connecting the valve cover to the plenum area. Unscrew the hose at the plenum and pull it off while it is at idle, then spray it in (if you are using "Deep Creep" by seafoam.) Spray a bunch in to the hole where the hose connects. You will be able to feel it sucking air. It reccommends 1/4 can. My engine doesn't stall out, though you can hear it bog down a bit. Just keep spraying. Turn the engine off and let it sit. I usually leave it for a few hours. Start it up and keep the rpm's up around 2500 for a few minutes. It will smoke like Marge Schott. I don't know it it really works or not, but I use it about twice a year because others on here swear by it. | ||

Take an empty 2 liter pop bottle. Poke a SMALL hole in the bottom on the side and another small vent hole on the top. Fill the bottle with water and block the vent hole. Start the car and hold it at a fast idle. Release the vent hole and dribble the water into the intake. Carefully, as to much water will stall the motor. Run through the entire 2 liter and virtually all the carbon will be gone. Why this works: Carbon is water soluble. The water turns to steam in the combustion chamber and virtually pressure washes the cylinder. | ||

Will try this tomorrow. I'll have to take it down the road a bit to do as I'm sure my neighbors won't like it. I already has some SEAFOAM in a can, I saw it at Advance Auto and picked it up a while ago. Just been waiting for the weather to break so I might as well use it, but that water method is going into my next time book  Also, another thing to add to this saga is that my truck is seeming to idle and run better as the weather outside is getting hotter (beautiful DC day). That seems odd and I can't figure out the correlation. | ||

Kevin - that is interesting - when is the last time that you changed the thermostat? | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 116 Registered: 05-2003 |
Hmmm, I don't know honestly. I bought the truck about a year ago, and I haven't changed it. | ||
| Joe B (Denverrover) Member Username: Denverrover Post Number: 176 Registered: 02-2003 |
Oh Kevin change that thermostat....it's easy, it could improve your gas mileage & it will keep your ECU from going into an open loop & you can use it as an opportunity to change coolant. Plus - it could fix your problem. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 117 Registered: 05-2003 |
but my temp gauge shows everything is running good? Wouldn't it run cool or hot if there was a problem? I'm just trying to I guess put together how a thermostat would cause my stuttering problem. Seems like a lot of people are showing up with similar symptoms. And from what I've read in the archives, Sticky Valves seem to manifest themselves more often in the moist warm temperatures, and my symptoms so far show the oppposite. I'll honestly have to take my disco in, it's not that I can't do it, it's that I have no place to change coolant and the thermostat. I live in an APT building that doesn't take to kindly to auto repair in the parking lot | ||

Kevin, My shop is about 20 miles Northwest of Baltimore. The thermostat is pretty simple to change, so any decent local shop can handle it. We use a device that applies a vacuum to the cooling system. This method fills the system from the bottom up, therefore avoiding trapped air in the cooling system. Plus, we specialise in Land Rovers! | ||

Just did the Seafoam Deep Creep in the intake this afternoon on my '97. The tap that I thought was a lifter must have been carbon on a valve. I let it sit for only the five minutes the can recommends, no real smoke to speak of when I started it, but the exhaust had an unusual odor for a few minutes. Now the former tapping valve is quiet. I will see how long it lasts. When I do the oil change next I will Seafoam the oil as well. I thought the stuff was snake oil, but it really seemed to work. I'm sold. | ||

Holy @#$% smoke screen Batman......used the Seafoam on my '96 w/ 86k today. Let it sit for about 10 min. and when I came back you would have thought the truck was on fire for all the smoke. Didn't solve the ruff idle, but I'm 99% sure it's an exhaust value issue. I used the SF to help clean things out a little before I tear the top end off for a valve job - also noticed a leak in the manifold gasket, but that will get replaced anyhoo.............Barry | ||
| Brian (Bthaxton) Member Username: Bthaxton Post Number: 98 Registered: 02-2003 |
I added SeaFoam at the last oil change in my '97 D1 with 110K miles. The only result that I noticed was the oil turned black a lot quicker than usual, which I assume is a good thing. I was a little suspect, however, in the fact that you are essentially "thinning" your engine oil with SF. This, coupled with the oil turning black quicker, caused me to change my oil again after about 1500mi or so. However, no problems. I would like to try it in the intake next, but where I live, smoking vehicles would be a no-no. That's why I'll probably do it at night. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 118 Registered: 05-2003 |
I'm still trying to figure out exactly where to use it in the intake on my 99 D1. If anybody has a pic or something of which hose or inlet to use, I would definitely appreciate it. | ||
| Barry (Boulderbear) New Member Username: Boulderbear Post Number: 21 Registered: 10-2003 |
Kevin, there is a hose about 6 inches long that connects the valve cover on the right side (passenger) of the engine to the right side of the plenum. If you disconnect it while the engine is running you can put your finger on the side of the plenum where it connects and feel the suction into the plenum. It is into this port you what to get the Seafoam. *Seafoam & Seafoam Deep Creep are the same thing - the Deep Creep is just in an aerosol so you can use it to spray it in. If you use the twist top Seafoam you will need to connect a piece of tubing to the port on the plenum & slowly pour it in - there is more than enough suction to do this without spilling it on the engine. Hope this help...........Barry | ||
| Kris Carlquist (Kris_carlquist) New Member Username: Kris_carlquist Post Number: 20 Registered: 09-2003 |
Brian, Did you add the SeaFoam to the oil? If so, you need to change the oil! I did it in the oil on my Trooper and the sludge it knocked loose clogged the oil filter. The Trooper engine has 150K on it, but still, you need to add the Seafoam engine treatment just prior to an oil change, I think seafoam recommends 1 hour before an oil change. This stuff is a pretty serious detergent and you don't need it in there for very long. If it can knock the kind of sludge loose that is does, I can't imagine that it is good for oil long term. | ||

where can one get some of this Sea Foam stuff? | ||

If you switch to synthetics, there would be no need to add SeaFoam, or any detergent, to the oil. Dino oil will carbon/gunk up engines eventually. And sooner if you drive short distances, <10 miles one way. Synth won't gunk an engine. I wonder if anyone running synthetic oil in a Rover V-8 since new, has had the carbon valve sticking problem? | ||

I am about to use Seafoam in my intake, already use it in the gastank. During the intake approach, will you throw a code becuase of the disconnect of the crankcase vent tube? Thanks in advance, Bruce | ||
| Brian (Bthaxton) Member Username: Bthaxton Post Number: 102 Registered: 02-2003 |
I changed my oil again after about 1000-1500 miles and replaced the oil pan gasket while I was at it. My pan and oil pump pickup got a good cleaning at that time. Actually added 3/4 qt to the amount of oil I had to put back in. Went from 6 3/4 qts for fill (with filter of course) to 7 1/2. | ||
| Blake Monchilovich (Azblake) Member Username: Azblake Post Number: 119 Registered: 02-2003 |
Same product for oil, gas and intake? Or just the same brand? | ||
| Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 628 Registered: 04-2003 |
Same product....it even says you can use in gas or oil right on the can. | ||
| Greg French (Gregfrench) Senior Member Username: Gregfrench Post Number: 713 Registered: 11-2002 |
Eric... It is my understanding that the valve problem is due to exhaust gasses on the shaft of the valve, causing it to not close all the way. This became a problem because of all of the "tweaking" they had to do to the old Buick engine to get it to pass emissions or something. If this is the case, I don't think it would matter what type of oil you use. Please correct me if I am mistaken about this. | ||
| mark gomez (Mark) Member Username: Mark Post Number: 56 Registered: 05-2003 |
I just wonder if it gets distributed evenly across the valves after passing through the upper intake and down the runners or if it just congregates on one side and burns up before reaching them all (in liquid form). Once it turns to steam, I would think that it would reach the intake and exhausts valves equally. So, is it the steam effect or the liquid that actually cleans up everything? | ||

Hey Guys, Used Sea Foam the other day in the white '96 disco. Did it as Greg recommended above, thru the breather hose, and ever since I've been able to smell gas whenever the engine is running. At first I thought it was just burn off, and it has weakened since, but I've put about 60 miles on it since, and still have that smell. Ive checked for any gas leaks, both with the engine running and not, and haven't found anything. My only thought is that the sea foam may have freed up the buildup along an axaust leak somewhere in the manifold, and it's gas residue I'm smelling before it hits the cats, but I haven't found anything there either? Do you guys have any thoughs? Thanks, Ry | ||
| Porter Mann (Porter) Member Username: Porter Post Number: 151 Registered: 05-2003 |
I used seafoam this weekend on the disco and didn't get any white plume of smoke. I've been using synthetic since I got the truck 3 years ago and I run Chevron's Techron fuel. I also used seafoam on my friends' Land Cruiser FJ40 after the disco, and that thing put out a smokescreen that covered the entire neighborhood! It was hillarious, people were closing their garage doors and windows everywhere while this thing just kept on pumping out the stuff. | ||

I did the seafoam treatment on my 95 Disco yesterday. A good bit of smoke but not enough to get me yelled at by the anti-car tinkering neighbors. The idle is improved and the exhaust leak was easy to spot from the smoke, so at least I know it's a gasket and not a cracked manifold now. This thing has to pass VA emissions inspection soon- been running techron in the fuel every third tank, the kerosene/oil flush. The engine is really sounding better than ever and oil pressure is up slightly and temp is down slightly since. Once the exhaust leak is fixed it should sound like new... if the leaking oil lines don't burn it to the ground first. | ||
| Will Cupp (W_cupp) Senior Member Username: W_cupp Post Number: 411 Registered: 07-2003 |
When did VA start doing Emmissions testing? I just had my truck inspected, but no emmissions testing that I know of. | ||
| Robbie Donaldson (Robbie) Senior Member Username: Robbie Post Number: 582 Registered: 02-2002 |
just the NOVA area I believe. I don't think the rest of the state has to do it. That's why I figure if my truck ever fails emissions, register it at my parent's place at Lake Anna. | ||
| S.C.Young (Youngsc) New Member Username: Youngsc Post Number: 38 Registered: 10-2003 |
Yeah- DC suburbs do emissions testing every two years. They are not as stringent as I've seen in other places, especially dealing with older cars. |
