SOURCE: Oil running out my tail pipe

Excess engine oil can only enter combustion chamber from four areas, (1) the intake manifold [pcv system failure], (2) Valve stem seals worn out [pluged oil return holes in heads causing oil to get sucked past worn seals] (3) Worn/varnished up/broken piston rings,(4) Highly unlikely but a hole in piston. Since you only show excess oil on left rear, suspect #2 or #3 although usually more than one set of rings will wear out or (gumm up).Check compression with all plugs out, ignition & fuel disabled, i believe 120 to 150 psi is good, if ok , check #2. If this has the older efi intake, its rare, but also could have a failed intake gasket for that cylinder and be sucking oil from underneath.Hope this helps!

The fuel pressure regulator does not seem to be working. It should hold fuel pressure in the injector lines. Your fuel pressure may also be to low.

SOURCE: 1996 Chev Cavalier chugging and stalling running rough idle

Bad injectors causing the vehicle to run poorly can cause other damages to sensors etc. Buy a code reader and check the codes.

94 tbi starts but dies unless u pump the gas it runs rough


This could be a whole range of problems from lack of fire to engine to a bad fuel pump or pressure regulator in the TBI but if all of that is good then check the Cat. converter to make sure it is not plugged or the muffler. As I have 1994 Chev Silverado myself I know you can pull the 02 sensor out ahead of the cat. and it should run better not well but better. It will relieve the back pressure to the engine.

How do you replace the fuel injectors in a 94 chevy astro


I believe a 94 astro has a cpi system this is a central injector with 6 tubes with poppet valves this located inside of the intake manifold,the top half of the plenum comes off and then the central injectoris inside,make sure your fuel pressure is up to spec also

93' 4.3 chev runs rough at times


Have someone turn the key on while you watch the injectors. If any gas leaks out of the injectors, without cranking on it) replace the o'rings around the injectors.

94 buick regal grande sport


You could possibly have a blown head gasket. Is there an awful amount of white smoke coming out of the tailpipe? If so, that's likely to be your problem.
