Hey, I had the engine oil changed in my D1 today. It has 184k so I opted for some synthetic. The shop put in 7quarts?? I now have a loud nocking coming from the rear of the engine just before the transfer case. Any suggestions to what it could be and what should be done before driving tomorrow. knocking is only present at idle, whether park or in gear waitng to drive. Cheers Trevor | ||

If its knocking near the Xfer case then its probably the trans and not the engine. Its unlikely that synthetic oil would make your engine knock. Try to figure out exactly where the knock is and describe it better. | ||

Thanks Ryan I'll kick it over in the morning and see what I can locate. | ||

Started it this morning followed the manual regarding checking fluids. It was about a pint low in the transmission. The knock appears to be at the back of the engine. it's a dull deep tap sound that is only present at idle, dissapears when the rpms come up. Somewhat quieter since adding the tran' fluid but still present. cheers | ||

I have noticed a few times that the dip stick gets bound up and hits the crank and will make a noise some may call knocking. Pull it and put it back in. Sounds silly but takes two seconds to try... "Blow me" | ||

184K? Thats getting up there. I was pretty much down to the copper layer on my main bearings at 165K.(But that was '90 3.9 engine) If you feel ambitious, drop the pan and check a couple of the mains. Then you can clean any layer of gunk from the bottom of the pan that is gar-ron-teed to be there, and you'll know the condition of your mains. Or try running 15-50 synth (or is it 20-50?) - OR drain out a quart and put in some Lucas Oil Stabilizer and hope for the best. | ||

There is little doubt that the rods and mains are shot. But its odd that it takes off knocking imediately after the switch... "Blow me" | ||

I have seen what Kyle says about the dipstick. Pull it out and make sure it's straight. Hope you didn't go to one of those quicky oil change places. If you did do what Eric says. Good luck. | ||

Doesnt 7 quarts seem like too much? My D2 only holds 6, but I dont remember what my D1 held. My advice to you would be to drain out the synthetic and put dino back in. See if the noise stops. I dont know why in the hell it would make a difference, but like Kyle said, it does seem odd that it happened right after the switch. | ||

with 184K you should not be running 30wt change the oil to a good 15/50 such as mobile 1 and add 1 quart of lucas oil stabilizer and I will bet it will be much less knocky. MM | ||

Synthetic oil molecules are all the same size. Regular oil molecules are sort of the same size. I am not going to give a refining 101 class but I doubt that the synthetic did any harm to your engine. The uniformity is one of the reasons that it lubricates better than just plain oil. I would double check the quantity that you put in. CAPACITIES Engine, with filter..........6.1 quarts[1] Engine, with filter..........6.7 quarts[2] Engine, with filter..........6.9 quarts[3] Engine, with filter..........7.4 quarts[4] 1. Refill capacity shown (engine without oil cooler). 2. Refill capacity shown (engine fitted with oil cooler). 3. Dry fill capacity shown (engine without oil cooler). 4. Dry fill capacity shown (engine fitted with oil cooler). This info is out of the AMSOIL service book. You can also double check all Land Rover fluid requirements on my web site or you can check your owners manual or ask the dealer (have your VIN handy). My money is on you have overfilled the motor. Good luck.....Dave www.JavelinaRacing.com | ||

Cam knock? The cam can float back and forth and hit the rear block or timing cover. The 3.9 is more susceptable, but could happen after enough wear in the 4.0 as well I suppose. Typically noticeable mostly at idle as higher rpms stress the timing chain more and stiffen it up. If so harmless, just annoying. I would agree the rod and main bearings are probably shot after seeing mine at 106K. Don't know if they would open up enough to be actually heard. If this is the first time using synthetic the filter may need to be changed as the dissolved gunk rains down quickly and can plug it up. | ||

Yeah Dave I was with you about the overfill but then I though there would be no way he has not checked his dipstick............but just to make sure......have you Trevor??? | ||

Check it with a warm motor. | ||

Sure it's not rockers? | ||
| Dave Smith (Javelinadave) Member Username: Javelinadave Post Number: 85 Registered: 07-2002 |
I guess if the rockers are a rockin you may hear some knockin.  | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 623 Registered: 11-2002 |
change the oil again to 50 weight and be done with it....30 weight in a super high mile motor is just plain incorrect. as the bearings wear the gap gets larger causing a thinner oil to flow out easier. a thicker oil keeps it in place so it can carry the load. go thicker and be done | ||

Back to your knocking problem. You sure it is a knock. how bouot a clank? It might be a bad muffler or cat. They will "knock" when idling and when RPM goes up you won't hear it anymore. Something to check first. Get under your rig and hit the muffler with the soft side of your fist and see if it rattles (best to do when exhaust is cold ). | ||
| Trevor K D (Nomad1964) New Member Username: Nomad1964 Post Number: 13 Registered: 01-2004 |
Matt affirmative dip stick checked. Corey good idea on the banging on the Cat' the nurse says the blisters will dissapear in a cpl of weeks. Wish I read the whole thread. Thanks chaps lots to get on with. | ||

Now mine is knocking... Only in Park/RPM'S go up can not hear the knock anymore....No clank..Oil was just changed this weekend.(Used 10w30 6 quarts) Followed all of the above suggestions. With the exception of dropping the oil pan and checking the mains...No time for that right now. 62.8K 1998 DI ..ANYBODY?? | ||
| Mark Sager (Msager007) New Member Username: Msager007 Post Number: 40 Registered: 05-2003 |
My cats went bad last summer and sounded exactly like knocking coming from the back of the engine. It was always the worst when it was warmed up and idling. | ||
| Melissa Nance (Roverchic) Member Username: Roverchic Post Number: 53 Registered: 02-2004 |
It is now more like a ping.... Only there when I accelerate over about 20mph, then it disappears... When I am stopped( no matter what gear I am in ) it is like cling, cling cling cling...then gets louder again disappears @ about 25..... Idling is awful.. Ping ping ping ping... I can not figure out where the noise is coming from ?? Popped the hood flashlight and all... under car..Could it be the cat converter?? It sounds like a lawn mower !!!!! | ||

Adding Lucas oil stabilizer. Now is that a relative of Lucas wiring of earlier LR's | ||
| sam (Dent) New Member Username: Dent Post Number: 18 Registered: 01-2004 |
melissa, your pinging sounds, along with rough idle sounds like rockers... take a look with flashlight where you put the oil in and if it's dark (black) you'll prolly need a valve job... or drop your pan, clean gunk out, add crappy oil with oil stablizer run your engine for abit.. drain... repeat again with good oil and change your oil again in about a month or so... | ||

I had a knocking noise at idle and low revs. Drove me mad. Turned out it was the fuel pipe where it goes thru the clamps up the firewall. Knocking noise was just pump noise amplified along pipes. When its idling check fuel pipes, push and pull. Bazzle 98 3.9 Series 1 (ozzie) | ||
| Melissa N (Roverchic) Member Username: Roverchic Post Number: 125 Registered: 02-2004 |
Sam I already had the valve job...AHH! I realized that it was the cats. Both had blown @ the same time. Bazzle I get that too (since I fixed the cats).. I have to change all the O2 sensors on thursday plus replace the power stearing pump, so I will check out that fuel pump as well.. The noise drives me crazy!! I am also going to change the oil 5 qts oil and 1 of the Lucas.. As far as clamps go for the new power steering pump, I just bought some @ Autozone.. Do you guys think that they will do? They screw down to 1 1/4 so I figured they would work? They were out of the ones @ the LR dealership.. |
