emergency ea81 oil burnage/spewage issue!
Posted 03 January 2004 - 02:35 AM
I replaced the intake manifold on this one and i removed almost all the emissions/vacume stuffs... and for some reason, it is having crank case pressure issues- I think the PCV valve is one of hte probelms, (which i will take care of tomorrow...)
but, to try and figure out where this oil is coming from, I connected the crank case breathers (on the valve covers) to the airbox (blue subaru one) and it seems to suck oil up from the breathers! (oil is sitting in the airbox)
we tried a different thing- took the oil cap off (with the breather hoses still connected to the airbox) and reved the engine up- it sprayed all over the place out of the oil filler!!! (too much pressure!)
another weird issue- with the airbox open, and engine running- poured a little trickle of water down the carb, (a good old time trick on how to clean engines out, and it does work) anyways, kept it running while pouring the water in by reving it up... seemed to suck the water down fine, but then water drops started spraying out of the passenger side valve cover breather!!! why??? how????? I dont get it!!??
could this be a blown headgasket? (not likely, considering there is no antifreeze or water in the oil, and no bubbles in the coolant)
is there something in the heads that could be cloged and making the circulation of oil in the bottom end of the engine not happen?
what would cause too much pressure in the crankcase?? (even with the cap off and the breather hoses opened up)
even the dipstick had oil pressure issues, it started spraying out that hole when i took it out!
this is sooooo frustrating! please help!!
(thanks Ed and Corky too for the advice! on the PCV valve, i checked, and it said "made in USA"... I need to find an OEM valve!)

It is a complicated system that works very well. It will help keep your oil clean, make your engine last longer, and cut pollution dramatically.

Ok so time for compression check. The driver's side cylinders both registered at 155 psi consistently. Now, while I was testing this side I could see liquid blasting out of the sparkplug holes on the passenger side and it wasn't gas because I drained the fuel system. Sure enough, when I checked compression on the passenger side, they were both barely 100 psi, and it was a very gradual climb to get there. This time, when I started the beast up to move it, i got that dreaded white smoke cloud. Another thing to mention: the spark plugs on the bad side had rust on them.
Turns out to be a bad head gasket. It figures though, I've been hot rodding the crap out of it in the snow.
Anyway hope this helps, good luck
