uh oh. installing MBC wrong = oil everywhere

[Novablue454]

so basically here is the deal. A few friends and i tried to build and install a MBC tonight and im pretty sure it couldnt have gone much worse. The tutorial we used had really good instructions and photos and how to build it, but got really shady on the how to install it part. so we did what seemed the most logical. well i drove it for about 5 min really easily to let it warm up and then romped on it once. it went straight to around 23psi. bad news. a few seconds later i got to see the white cloud telling me i messed up. what would be leaking so much oil? I dont think head gasket because usually thats coolant. another friend of mine said it coiuld have lifted the valve cover, but there is oil in top of it so i dont know. any help is greatly appreciated.

Could your oil dip stick have popped out? and check the oil cap..

White smoke? doesnt sound like oil. To me I would think at 23 pounds it was running lean as a mofo.

 

[T is for TURBO]

white smoke=coolant
blue smoke=oil
black smoke=fuel

Do you actually see oil leaking? is it leaving spots on the ground? or is it just blowing smoke out the the tail pipe?

If its blowing smoke out the tail pipe and the smoke is white, you could have blown a headgasket.

Shawn, that is generally good info, but I remember my first time popping my dipstick (disregard the sexual undertones here ) and there was only white/light grey smoke from when the oil hit the exhaust manifold heat shield and head.

I have to agree with VPrime here. I only do so because I am assuming what the OP means by his question. But the OP needs to be more specific. How much smoke could you see, and where was it generally coming from (under the hood, or out the tailpipe)? Also, are you completely sure it's oil that is burning, or is that just a guess?


Additionally, be careful of holding down the dipstick in the future:

I'm not a big fan of these mods because they attempt to band-aid a bigger problem. You could epoxy your dipstick in place, but for whatever reason, the crankcase is still being pressurized. You need to find out exactly HOW it's getting pressurized.

its definatley oil. its on the valve cover, the exhaust manifold, the ac pump, and a little on the fan shround. there is also some on the ground underneath the car. All the smoke was coming from under the hood.

Like said above did you make sure your dipstick didn't pop out.. That is a simple thing too check first... secondly check the oil pan to make sure of no cracks, Did a knocking start after or did it run fine just oil everywhere? if the pan is cracked and theirs a knock..well theirs your answer, if not it might have been something that just popped off sumwhere, check all lines from turbo/valve cover etc..

You should have been able to figure how to install the MBC http://www.dsmtuners.com/forums/showthread.php?t=237982

If you have oil on top of your valve cover it sounds like the dipstick popped out, to much crankcase pressure.

Was there any oil residue on the underside of the hood? Did you have the exhaust manifold heat shield on when this happened? What I am getting at is if you did have the heat shield on like you're supposed to, then there is a difference between finding oil on the heat shield and finding oil on the actual exhaust manifold. In other words, assuming you had the heat shield on before this occurred, then you experienced this problem, then you popped the hood and removed the heat shield and then found oil residue, that would not be because of your dipstick popping up.

My guess would be that you installed the MBC wrong so you saw unlimited boost, pressurized your crank case, and popped your dipstick. I had this exact problem. I installed a check valve and new dipstick and solved the problem. My old dipstick could not hold itself in. The rubber seal on top became plastic over time and did not seal. The new one held itself in great.

hey whats up guys um check your piston rings and check your oil dipstick and see it if it comes out with WOT and if it does you have blow buy and your building pressure in your block are you on stock block and head it could be your head to check your compression

WTF ..........
How in the hell are you suppost to check your god damm piston rings??? Grow up, if you dont know what you are talking about, then don't post shit like this.
To the OP: First thing to do is to check what everyone has been telling you....the dipstick. If that didn't pop out, then pull each plug and see if there is oil on them. Another thing to check is to see if there is any water in the oil, or oil in the water. Then proceed with the compression check to see if indeed you have a bad headgasket. Also pull off your LICP and see if there is oil in there as well. Could have blown a turbo seal, or even have a blocked oil return line. If you are indeed getting blowby, replace the PCV and your oil cap. This is all i can think of right now.

Another thing is if its your first time to have other than stock boost...then it might be oil coming from the oil cap. when i installed my mbc my oil cap would leak. All i did was go to Advance auto and got a new cap and solved that problem.

 

[Novablue454]

ive narrowed it down to two things i think. i definatley blew out the dipstick because when i pulled it out there was oil all the way up to the seal. it didnt seem to be leaking out of the cap because all of the oil was on the front area of the valve cover. so its either that or I blew a turbo seal. im thinking that because the smoke seems to be coming from under the heat shield. i put all the lines back to stock and now its back at 10psi. it still smokes a really tiny bit but i think it might just be the old oil burning off. thanks for all the help so far and for not flaming the noob

A dry/wet compression test has always been a great place to start as far as rings are concerned. He was just offering some suggestions don't be so rough on the newbies.

Reseat your dipstick. Clean the oil off of everything. Use Simple green and a rag and sparringly amounts of water to clean the oil as best you can. It will still smoke for a while as the oil burns off. Refill your oil and possibly change the filter. Inspect the drained oil for signs of water in it. Do not start the car or attempt to crank it until you have refilled the oil.

Check your LICP for oil, as well as your Intercooler (probably need to remove and clean it anyways).

Follow the link posted above for properly installing your MBC... better yet toss your uproven and untested DIY MBC and buy a cheap IL series Joe P MBC to be safe for $45. Set it to its most "open" position for lowest boost.

Do a compression test anways, its quick to do and offers peice of mind. You should pull your plugs anways to inspect them for oil, so do the compression test then. Spend the $40 on the tester if you don't have one or have access to one, you will use it again and its a good tool to own.

If oil is still spraying, and the compression test was good then then it could be your turbo seals.
