As far as sludge goes...I would think it would have reared its ugly head long before now. I bought the car with 79000 on it, immediately did an oil change, and sinc eabout 83000 have been using exclusively Mobil 1 15-50 per Dimitrios' suggestion. It now has 88000. When I pulled the valve covers a few thousand miles ago they looked pretty clean. The oil seems to dirty at a normal rate, and it does leak/burn about a quart every thousand miles or so, maybe every 500 if I drive it hard. I've also not babied the engine, and I almost always drive it for at least 1/2 hour once its started. Interestingly, almost immediately after I switched to the Mobil 1, I noticed a drop in the oil pressure gauge; normally it rode about in the middle of the range, and after the switch it went to about 1/4 to 1/3 of the range. I figured maybe the gauge was bad, or maybe the different oil made the sensor read differently. Stupid me, I never installed an aftermarket gauge. No word from the mechanic yet. I smell mucho dinero, though. Thanks to everyone on the list for their advice, recommendations, and offers of parts. Truely a great list this is. Not one person even inquired about buying the car for parts, as I hinted at. Its great that everyone's so committed to keeping these things on the road, as many as possible! ===== --Mike Pittinaro "Peculiar travel suggestions are dancing lessons from God." --Kurt Vonnegut, "Cat's Cradle" __________________________________________________ Do You Yahoo!?
