Lets see if you guys can solve this

[Russman]

I have a 1994 Lumina Euro 34 that I just bought. The guy I bought it from said it was fouling the rear bank plugs and he just didn't want to deal with it, I only gave $400 for it as I might need to change the engine. Is there a possibility that these plugs are fouling due to an easily fixxed problem?
Is there a chance that oil is in the valley due to a bad gasket and is getting into the ports somehow?
Right now I'm not even sure if the plugs are oil fouled or fuel fouled.
When I start the car,its not running on all 6 cylinders and there is a substantial blueish cloud from the exhaust that didn't seem to clear up, no knocking though.

if it's oil it could be fromd the distributor plug o-ring leaking. they all will eventually. maybe the o2 sensor also

O Ring doesn't go into the cylinders, it goes on the ground. Leaves a mark where you park. And I can't think of any scenario that leaves blue smoke, other than burning oil. Anyone want to argue this? Check your plugs and compression. Find the bastard cylinder and go from there.

easy: smell the plugs. if they smell like fuel, they're probably fuel fouled. if they dont, they're probably oil fouled. then, go from there.

also, blue smoke is usually indicative of bad piston rings or something similar. try some bg moa. if it fixes it good, if not, you probably need some engine work.

those are my thoughts, correct me if anyone has any different input

Wild ass idea here. Did you or the other guy even pull the rear plugs? Ive came across people who consider replacing the front three a "tune up" cause the rears are "hard to get to". Anyway do a full plug read and go from there, such as a compression check.

Thanks

Thanks for the input guys, I will tackle this problem when the weather gets a little milder as I am a fair weather Mechanic (no garage) and I live out in the sticks in Upstate NY so it gets mighty cold out here.
Thanks again!

Fuel injector stuck open. replace or get reconditioned.
