s'ko Posted February 10, 2008 Share Posted February 10, 2008 I had my engine on a engine stand and when I tilted it towards the passenger side, oil started to pour out of the front intake port. I plan to remove the heads but does this mean that I have to rebuild the bottom end? I never had the engine running so I don't know what the issue it. Can I test compression if I the intake manifold is of? BW Link to comment Share on other sites More sharing options...
aircraft engineer Posted February 10, 2008 Share Posted February 10, 2008 well, there are 2 ways for oil to get into the intake - 1) hole in a piston (and you'll know that when you pull the head) 2) really bad valve seal (but "poured out" - not likely a seal) You must have had it upside down to get oil out the intake port. You can get a "cylinder leakdown" tester and check not so much the compression, but how much "blow-by" there is. (advantage is that you don't to turn the engine, just set it to TDC and hold it there, apply the air pressure and read the result) I'd suspect a bad piston Link to comment Share on other sites More sharing options...
s'ko Posted February 10, 2008 Author Share Posted February 10, 2008 It was on an engine stand. Removed the head and there is no hole in the piston. The other head is on, and when I turn the crank, there is a noise like air being forced into the crankcase. The other side pressurizes and releases air like normal. I know that these crankcases have positive pressure so I assume its normal. The noise is not air pushing past the rings b/c when I cover the cylinder, the noise is not muffled. Before I put it on the stand, it was sitting on the front crank pulley for about a month or so. Given that it was in this position, would be oil have seeped into the cylinder. If that is the case, then why not in cylinder 2? it's sounding like i will have to rebuild the engine completely. :-\ but I hope I don't have to. The engine is a EJ22T and it has 161k on it. It was running when I got it from cyberbackpacker. Car was rear ended and totaled out by the insurance company. bw Link to comment Share on other sites More sharing options...

[/quote']\ this may have some effect on the thrust bearing though??? might want to make shore you do crank bearings??? Link to comment Share on other sites More sharing options...
s'ko Posted February 10, 2008 Author Share Posted February 10, 2008 \ this may have some effect on the thrust bearing though??? might want to make shore you do crank bearings??? OK. Maybe not a month. It was about 2 weeks and not resting directly on the crank pulley. It was sitting on a moving dolly with the flywheel up. Would that position allow for oil to leak into the cylinder? Also where do I get bearings and rings. The only site I found was Paeco.com. Any other places?

I experienced the exact same thing myself- had a low mileage ej22 sitting on its side for under a week and one of the cylinders filled with oil. Cleared it out, installed the engine and it runs great with negligible oil consumption. Piston rings aren't designed to seal against static oil pressure! Inspect the cylinder bores for wear if you like and you'll probably be fine. Nathan Link to comment Share on other sites More sharing options...
OB99W Posted February 10, 2008 Share Posted February 10, 2008 [...]An engine in good condition WILL do this.[...] Piston rings aren't designed to seal against static oil pressure! Agreed. Given that the engine was previously okay, it's unlikely that sitting in an unusual position would cause damage. If nothing else, piston rings have a small end gap that typically almost closes when the engine is warm. With a cold engine, a couple of weeks is enough time for the oil to find its way through small gaps. Inspect the cylinder bores for wear if you like and you'll probably be fine.Yes, do check the bore for scuffing/scoring and taper, but it wouldn't be surprising if nothing significant is found.
