good to know. Also...I was doing some reading and decided to do more poking around with the stethoscope. What I thought for sure were my lifters now seem to be my fuel injectors. One in particular is extremely loud...I unplugged the connector and the noise got a lot quieter. I know it's not dire, but I'm looking around town for someone who'll clean them well, maybe rebuild..I won't have enough down time to send them to that Mr Injector. There is still a faint ticking coming from the block, and when I pulled my throttle body awhile back there was THICK black buildup inside the intake, which I've read could be a by product of a collapsed lifter, or just age. I'm still going to pull the engine to take care of my oil and coolant leaks, but am reconsidering the lifters until I can be more certain. They take a lot less effort to replace than the oil pan and rear cover gasket, I can always do them down the road when I'm certain they're a problem...I'll probably post some pics of the broken things soon just to pass the time on the thread till I get my tax return back and afford all the stuff I'm going to do. I'm probably going to put a PLOG on too while the engine is out, just to make it more fun.
