So I opened up the hood today to see oil all over the right side of the engine as you stand in front of it. I noticed my Dipstick flopping all over the place in its hole. The grommet (or whatever you call it) that holds the dipstick securely in the hole, has withered away, and is in need of replacement. Has anyone ever had this happen to you? I did not know it would puke out so much oil, almost a half a quart!
 
your PCV valve is plugged. it allows pressure from the crankcase to be sucked into the intake
 
it is 22R carbed.

I believe this is the problem after going out and looking at it. Run to AutoZone and get a new one tomorrow. Dan knows about the engine, he helped put it in.
 
You say it can't be the PVC?

Have you checked to see if you have a bad exhaust valve? You obviously have a back pressure problem.
 
Mine did the same. Somebody gave me a used stick. My rig runs high oil pressure so I also lost about a quart before I noticed.

My comment was for the rings are shot, It is hopefully the PCV valve.

It is a fresh engine.

His last engine had 0 lbs compression on one cylinder and 30lbs on another.
 
i had a bad dipstick in my 87 pick up with efi and i never blew oil out the hole. so i would look for what is causing the back pressure or blowby. pcv or may be even check your cat. it could have even caused your rings to go bad on your other engine.
 
You can't compare to the 22RE, that engine should have a slight vacuum on the crankcase, not pressurized like the 22R. That's why I asked for clarification in post #3. Try it next time, truck warmed up and idling, pop your hood and remove the Oil fill cap. Your engine might die from the massive vacuum leak, but if you quickly slap your hand over the fill hole you'll feel a slight vacuum.

A nerw PCV valve is a cheap thing to try, if that doesn't help than I'd be doing a leakdown test.
 
I figure you are not talking to the po. Just in case you are not he said he had a 22R.

yea asd you know ,the 62 does the same as you speak of:)

I've never heard of a pressurized crankcase. My 22r has a PCV valve (Positive Crankcase Ventilation) as did every other vehicle I've owned even if it was just a vent on a valve cover.
 
Sorry, "pressurized" is probably not the correct term. What I mean is that the engine crankcase is under a very slight positive pressure, similar to how many buildings will have a positive pressure for ventilation. Lots of things cause this positive pressure, but even new engines will have a small amount of blow-by. The PCV valve is supposed to be the relief point of that positive pressure, so excessive pressure in the system can be the result of a faulty PCV. But, if the blow-by from the rings is excessive, then the PCV can't keep up.

The 22RE (and the 3FE) has a slight negative "pressure" (if that makes sense) in the crankcase.
 
I swapped out a new PCV valve, and shook the old one and it moved fine, so not sure if that will be the problem. I still have to do a compression test. I have an oil leak near new timing near the dipstick. So far I replaced the Timing cover, dual row timing chain, steel guides, oil pump, front main seal, and rear main seal.
 
Hey Bailey, I will give ya a call after this weekend. Thanks!
 
hey klf was right at idle a 22re does have a vacuum as stated by him but if you have ever left your oil cap off while driving it blows oil every where. but for oil to come out of your dipstick hole there has to be a problem. the rubber on your dip stick could be bad or it could be worse. or you might have not pushed it all the way in. sorry to say the later but i always like to look at the most simplest thing first. hope you get it fixed.
 
I appreciate all the help guys! Its nice to have a forum that you can learn from. I have a long way to go, but have learned a lot so far! I just dont want to have to replace the engine again. If it is bad, I will just rebuild this one. I am getting another Toyota for a DD soon (98 Tacoma 2wd, 3.4V6), so it will be nice to be able to take my time and get it fixed right if need be.
