running rich or lean? just bad
alright so I know that an engine with 297K+ miles on it has to be comming to an end I thought of that when I bought it as a parts car for its transmission and it drove so therefore I went ahead and drove it and I still am, but latley its been getting really really slow. at first I thought it had a blown head gasket from the loss of coolant but after replacing the radiator things were alot better. then last friday I thought to myself "change the spark plugs stupid" so I pulled them out and they were all just really dirty except cylinders 3 and 6 which had some oil build up on the spark plug which is sadly probably the oil seaping up past the rings. but its overall really slow compared to 3k miles ago so what can I do. It doesnt seem to be running right, maybe a little rich by the opinion of one of my friends. it just doesnt have that get up and go that it had 3k miles ago
thanks for your input, I plan to swap the engine anyway I just would like to take this to 300k and then swap it
if you have any input on a more performance setup please speak up I have 3 of these engines now 1 has 150k on it and a dropped a main bearing so its declared dead untill I take an engine rebuild class at college then I have an engine with less than 3 or 4 miles on it *candidate for swap* and this engine in the car with close to 300k so I can do internal mods or should I sell all of them and buy another engine to put in?

Since it's on its way out, maybe you can do some experimenting with those engine restorer products they always have at Pep Boys or AutoZone, see if they work at all for restoring compression. At this point you probably couldn't do worse damage anyhow. I doubt it'll work, but hey- it's worth a shot for a couple of bucks.
On another note, maybe get your injectors blown out if you think it's worth it.

I agree with Dudesky, it's experiment time. |
