this engine is kicking my butt,looks like my electrical problems are going to take a backseat until I finger out this major problem. I have been noticing my car has been eating coolant.I have checked for leaks and cant find anything.Today I checked the coolant and it looks like sludgy coffee and it was low again.I think the coolant is coming out of the tailpipes because my rear bumper (which is white) gets a splattering of some type liquid all over it.The car does smoke at wot but thats the only time.I also pulled the line that comes off of the pass valve cover and connects to the throttle body and it had white crap in it which might be normal because of condensation I dont know.When I checked my oil dipstick it looks good. besides all these problems the car runs very strong.So any opinions?

Probably a good idea to start a new thread for the coolant loss/sludge/etc. problem.
