Background info. 1.6L B6 engine with 110k Miles.

Car was running okay, but seemed to have some blowby, because oil would be coating the intake piping, and it wasn't the turbo, as I decided to vent to atmo and intake piping was okay after that.

So I have some blowby. Don't think much about it. Removed GReddy kit, installed Fuji IRTBs. Car runs, but runs really rich, but other than rich, seems to be okay. Drive about 70 miles. Notice that the newly installed catchcan had caught about 1 qt of oil in 70 miles. OMGWTFBBQ?! Figured it was because I had capped my PCV valve. So I decide to uncap PCV and run 1 line from the PCV into the catchcan and the other line from the vent thingy on the driver's side into the catchcan.

Car seems okay, albeit running rich.

Decide to put in 1.8 injectors in for a little while, while 1.6s get sent out to witchhunter for cleaning and balancing. I take the car for a drive, about 10 miles, and a lot of white smoke starts coming out.

Ruh-oh. drive home, fuel, oil, water levels seem fine. Decide not to drive the car til I get injectors from witchhunter back. Get injectors back from innovate and install Innovate Wideband to see AFR, and I do NBO2 simulation so that I can run the Innovate in lieu of the stock O2.

Innovate LC-1 is saying car is running lean. No way in hell it's running lean. 25:1 AFR. So I'm like okay um help innovate. Innovate says there is an exhaust leak. Ain't no way there is a exhuaust leak.

Do some searching, and seems like oil is getting diluted via extra fuel due to rich condition. Decide to change oil. Changed oil, oil smells gassy, put in new oil.

Start the car up. Pray that engine smokiness would go away. No smokiness but as the car starts getting warmed up smokiness comes back. So I figure I'd take a look at the oil, see what it looks like. Shut off the engine.

Then a Geyser of oil and probably something else SPEWS out the dipstick hole. OMGWTFBBQ! stick the dipstick back in, oil everywhere I HATE YOU OIL.

I've never seen such a thing. Any ideas? Could blowby cause so much pressure that it would shoot oil out of the oil diptsick hole? I'm thinking of pulling the head :(

 

bad rings. just do a compresson or leakdown test

 

golly gee darn dang nabbit! So if new rings, might as well put in a used motor no?

 

there are a few used engines on craigslist around cali, so you should find one easily.

 

Yeah that whole spewing oil out of the dipstick thing happened to me. Looks like we are in the same boat.

 

how'd that happen to you newb?

 

So did a compression test all were in the 180-195 range, then did a wet test and the difference was greater than 20%, and my mechanic neighbor said that the rings were toast. :( boo.

 

Ring blew out.. put alot of pressure in the crankcase.. popped the dipstick. Oil alllll over. On another note, dropping the car off at RP Performance for the rebuild today.

 

who know how it really happened....that's just what the aftermath was.....

anyways sweet man you gotta keep us updated, makes me want to find a blown one of my own and join the Belfab club.
