That looks nasty. Funny thing though: I showed up over at a friends house last night right after he cracked the heads off his 80K '95. It looked as clean as a whistle inside. I mean it was truly amazing. Of course, the leaky head gasket was allowing enough ingress of coolant to give the inside of that motor a nice "steam cleaning" -Curtis | ||

yep, the last 3.9 valve job i did was as clean as could be with 81k. but not the case for this 97 4.0 | ||

What type of oil were you changing it with, and what octane gas/brand were you using. I'm curious to know if octane level/oil/brand has any correlation | ||

Friday I helped a buddy pull the small block out of his Jeepster. Pulled the valve covers off and very clean. He swears by Valvoline 4X4 oil. Heck even the oil in the pan was still golden colored. I think i'll start using it now. | ||

What on earth did Land Rover do to create this kind of mess. Granted they aren't the only one Toyota has had problems with some engines due to the tightening of pollution controls possible resulting in retention of oily wastes inside the engine.....and they sludged up just like this FWIW my 95 d1 with 132k has a patina of brown inside the valve covers. 5k Mobil 1 for last 70k | ||

I use nothing but 93 octane usually Amoco, sometimes Chevron. I have been using Castrol 10w40 for the last 40k. changing it every 2500 to 3k religously. i feel the damage was there before i got the motor.its hard to believe it looks like that. but it goes to show you that some damage cant be reversed.i drive the shit out of my truck,and i am sure that if i was driving normal all that gunk would have stayed put on the walls of the motor. but with all th oil sloshing around it just started breaking apart and ending up in the pan/pick up screen. | ||

I thought my 97 4.0 was bad. I feel better now. All my crud was under the valve covers and top of the heads. | ||

Holy crap! Is this the same truck you used at the FLRC Fall Rally? Wonder what caused that kind of build up? | ||

It probably got its first change at 45k when you bought it. Ron | ||

"synthetic amsoil...works like a charm!!!" Isn't that the stiff that is basically Amways Oil (amsoil)? | ||

Gotta keep the breathers clean. Toyota had same problem (for different reasons - trying to lower emissions). Without good ventilation, the stuff distills out in the motor. | ||

hey Mark, you have the white 97 disco dont you? yepper thats out of the same truck i drove during the FLRC gps hunt.i still dont believe it. i am diligent about servicing the vehicle.so yes i think its first OFL was when i bought it and did it myself. i am looking at the bright side and saying, yahoo a new motor of my very own to love and hug and caress and well,hold on i need a moment. | ||

I have seen this before in other cars. It is a sign that the oil was not changed regularly (if at all). This is the kind of thing that dealerships take pictures of to show the customer why their engine rebuild will not be covered under warranty. | ||
| Roger Fastring (Fastring) Member Username: Fastring Post Number: 53 Registered: 02-2003 |
I respectfully disagree. My 95 looks similar and has been pampered with 3k mile oil intervals. Some engines just have poor tolerances and its either blowback or ? that gums them up. I just dropped the pan for the second time on mine (124k) to clean it out and try to reseal the pan for leaks. | ||

What Geoff said - keep yer breather filter(and air, and oil and fuel and transmission ) clean and motor would be one happy puppy. | ||

I don't agree with the "It is a sign that the oil was not changed regularly" statement. It should say, "it CAN be a sign..." I have a Saturn with 78K on it that I'm having to dump 'cause the engine went south. When they opened it up to see what was going on, sludge-city!!! The mechanic said it's either a sign of not changing the oil often enough or a lot of start-stop, short city driving. Sorry, bud, NIETHER! I changed the oil & filter in that thing every 3K miles, religiously (Castrol), and it's ALL highway miles at 75-80MPH since my job keeps me on the road (average 35-40K/yr). So, I don't think you can point the finger at one particular thing here. In my case, who knows! It could be the oil/gas type combo. I used to burn premium in it, but started burning regular around the first of this year. Did that have something to do with it? Who can say for sure? | ||

Jay, after reading your post i see that you used Castrol also.changed oil every 3k and had sluuuuddggggee. I used nothing but castrol. also the saturn motor is alluminum. i really feel as if a higher detergent oil would have kept this from happening, you know the old addage drive your motor clean. there is some truth to that.I had some guys say that it looks like exhaust gasses cooked the oil causing it to scab. well there was no blow-by at all so thats a hard one to put together. i will say that i am now using Valvoline for the break in of the new motor. |
