Bought a car for FE but im having trouble need Mech help!!!

[Tepco]

I think he means the first fillup was a 1/2 tank. not everyone runs the tank empty.

Exactly, i just filled it up after i used a half tank after the first fill.

Compression tests should be done with a fully warmed engine, the throttle should be open (gas pedal pressed) and the engine should be cranked 3-4 revs (the needle will jump each rev), disconnecting the wire going to the coil will keep the engine from starting while doing this, you can also pull the fuel pump fuse to keep fuel from being dumped, or the engine from firing, but with a warm engine your compression should be around 195psi, so 180psi with a cold engine is good

Thats how i did it, the engine was warm, all plugs removed, fuel pump disconnected, gas pedal to the floor. The shop manual says 185 max and 135 min. So i think I'm OK with the compression readings.

I would try cleaning out your entire intake, as it sounds like your PCV system was causing some problems, it sounds like you either have a blockage or a leak allowing your crank case to build up some pressure and let oil leak past your rings, so I would clean out all the passages and hoses, and check for leaks, this will hopefully reduce the smoking, and improve your gas mileage

.

Is there a way to check how much crank case pressure i should have, or a good way to check if my PCV system is working properly? When i squeez the PCV hose the valve doesnt rattle, but when i take it out, the engine revs up and there is a lot of suction in the hole where the PCV goes. When i have the PCV in my hand it rattles as its supposed to.

the smoke is textbook symptom of bad rings, i'd vote for cyl 2 (as engine cylidners are always numbered from the timing belt end) do a wet compression test and get back to us.

Yea your right, cylinder 2 is suspect being the lowest in compression and leak down. Ill do a wet comp test as well as a leak down test while the piston is lowered down the cylinder. I heard that the wall could be damaged further down and can be detected that way.

Thanks for all the info, keep it coming and ill update my results.
