Bad Engine

05-03-2006, 01:57 PM
I just found out that the #7 piston is @ 25 PSI. They tell me that I need to rebuild the entire motor, it will cost about $2,500 dollars. I have a 4.1 engine in the car. Q, can they just fix the bad piston or should I go and have the entire motor redone. The car has over 140,000 miles on the meter. HELP

Get a 4.5 Cad engine, direct replacement, quite a few suppliers out there also try GM Goodwrench engines. The 4.1 was bad from day one, don't waste money fixing yours.

OK, I'm having low pressure (25 psi) on my #7 cylinder, will I need to replace the motor or just fix the cylinder? HELP Me OUT!!

You do not know what is wrong till you pull the and head/or piston, also check the camshaft this was another problem, how can anybody answer your question without knowing the exact problem?

Well I broke down and replaced the motor with what else a new 4.1 out of the box. I just can't see myself changing the motor to some other C.I.. See runs great now. :)
