Ok I have been dicking with this for a couple days now and cannot get it to stop. As alot of you know I just got my motor rebuilt, if not well now you do. My problem is when I start it , oil blows out the oil pan gasket like crazy. I have replaced the oil pan gasket thinking maybe the cheap paper one that topline gave me was junk but still have the same problem. I dont have my oil pressure gauge hooked up yet but know that it has to be a extremely high oil pressure problem. How or what can I do to fix this?
any help appreciated thanks travis also if anyone would like to purchase the car its up for grabs. $4700 firm. I am getting married in three months and could use a little extra cash.

High oil pressure won't cause oil to blow out of the oil pan gasket. That is just a bath of oil in the bottom of the engine. The only way I know that oil will blow out of the oil pan gasket like that is due to too much crank case pressure. That normally only happens on high mileage motors with loose rings. Things I would ask:
Is the oil only coming from the back of the oil pan after driving? If so it may not be pressure build-up but just a bad seal between the pan & engine. Are the rings seated yet? Did the engine get a propper break-in? If not I wouldn't recommend boosting on unseated rings. Is your dip stick blowing out or are you getting a lot of oil from the valve cover vent that would indicate high crank case pressure? Hopfully some of these questions will lead you down the correct path. Good luck

Thanks but I havent even got to drive it out of the garage yet. It happens when I start it and it runs for about 5 seconds.
The rings cant be seated yet and Im not running any boost thanks for your help but need more!!! -------------------- "One of the most Crazy and Undecisive Members in central Illinois"

Have you done a compression check on the new motor? I think that kicks is on to something with the loose rings. I am going to guess that you may find a low cylinder. If you have the capability to do a leak down test you may find that you can reproduce the leak without starting the car.
Combustion >>> Past the rings >>> into the crankcase >>> Out through the pan seal

Use grey silicone on the oil pan with NO gasket at all. Run a bead around the pan, making sure to go completely around all the bolt holes. Let it set up a while and then bolt it up.
Then do what Kicks said ^^^ -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

The main cause of high crank pressure is blowby past the rings. Do a compression test and see if that's the cause.
I would ditch the gasket all together.... -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

I will do the compression test tonite and let you guys know what the results are. If blowby happens to be the case what the heck am i to do since its a basically brand new motor?

You're not running synthetic oil during the engine break in period are you?
Seal that oil pan up first. That's probably your main issue. If the rings arn't sealing, I would take it back to whoever built your motor. -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

That would be me.
I you haven't gotten it out of the garage, the rings aren't seated yet. I guess there's always a possiblity of getting a faulty set of rings... Two questions that kicks asked that I think would tell us a lot... Is your dip stick blowing out or are you getting a lot of oil from the valve cover vent that would indicate high crank case pressure? Also, what kind of sealant are you using? Make sure you give it pleanty of time to dry, and are applying it to a clean surface. It won't stick to oil, no matter what you do. I think before we all jump to the conclusion that the motor's bad we should get all the info.

I will get everything together and do a leak down test tomorrow. My dad ( being a master technician for 22yrs. ) Has been thinking about it also. One thing I noticed is that my oil pan gasket is not blowing out with the oil. So with this thought we are going to check to see if the block may have a crack in the leaking area. Anyways ill will have more info tomorrow.

Noticed he posted a want add becasue the block has a crack in it. Might try welding it up if it's just leaking oil, rather than tearing it all back apart and starting over.

Can you weld the block? I thought it was iron or something you cant weld?

not a welding expert, but I think just about any metal can be welded with the right equipment. Cast iron is pretty tough, but I've seen it done before.

If your welding on cast iron you can try to create a controlled environment in which you could use a well placed thermite charge to weld the crack. Or if your felling lucky JB Weld that sucker

I thought about jb welding it but would rather weld it if it needs it. I have come to the conclusion that the piston ring gaps have lined up wrong so I have to take the motor back apart. Fun Fun!!!

What led you to the conclusion on the ring gaps?
