Time for a rebuild??

Hey guys, looks like I'm in need of a rebuild I guess ?? #2 cylinder spark plug has oil all over it. Just changed it about 25 miles ago. Blue exhaust comes and goes.

You need to determine if the oil is getting past the valve seal or past the rings. If it's the valve seal might just need the heads done. Do a compression test and leakdown test.

If a valve seal, you can even replace them while the heads are still on the motor...

You might luck out by just retorquing the intake manifold bolts.
Gasket could be leaking from lifter valley into the intake port.

Re: Time for a rebuild??

Well Donny here,s my take on the above all is true. First you have to determine what the problem is bad seal,worn valve stem bad guide stuck or bad rings etc. If the rest of the engine is good but a little tired fix the guide or seal lap the valve in and put it together and drive the car untill your ready to go through the whole thing. I you put a fresh set of heads on a tired bottom end within a short while you will have a real oil burner on your hands. Compression goes two ways if the engine is tight it goes up and makes power if the engine is tired and loose it goes down blows out the rings and into the cranckcase. This is very old school sound advice there will be those that may not agree with me on this but my years of experiance tell me different. Good luck i hope its just a valve seal. Alex
