Bad Oil Seals?

[dugan33]

Alright so my problem has always been there since ive had the car. It was the dipstick popping out problem.. so somebody told me to jsut crimp it and i did. problem solved so i thought, until now. I started noticing oil in my blow off valve. i thought it was the oil seal in the turbo cause it was a cheap ebay turbo. so i bought a new big 16g. i installed it and i think the problem just got worse. There is even more oil in my intake system and its all over my intercooler. I've cleaned out my throttle body and piping. and while cleaning i noticed there was oil on my timing belt.. soooo then i was worried even more so. Thing is its possible that oil came and shot across my engine from my blow off valve, ya there was a lot fo oil. is there any good way to check my oil seals? and how do i fix my blow by issue anyways? its jsut one problem after another with this car.

The reason it was poping out is that you crankcase pressure was escaping through it when it built to high. Now that you closed that it has to find new ways out ( and can take oil with it). I would check your pcv system for more oil and if there is get a catch can.

How is your PCV system set-up? If you are on the OEM PCV valve I can almost gaurantee it leaks, if so, then you are blowing boost from your intake manifold into your valve cover, a BLT will help define the issue much more. A US plastics check valve is used by many in place of the PCV.

You can also simply remove the PCV and see if you can blow through it, intake>valve cover, if you can then it is leaking. You however would want to be able to blow from VC>intake though.

Usually if you have oil on your timing belt then you have a gasket leak in the timing case area.

Also check for excess shaft play on the turbo.

It would be a good idea to compression test the motor too.

I agree, seems like you have excessive blow-by. It sounds like the PCV is working since oil is collecting in the intake, but it's too much for the line to handle. Hence the dipstick popping out and oil seals leaking. And since you have a mostly stock engine, upgrading the PCV system or installing catch can would just band-aid the problem.

It would be good to check the PCV system (especially PCV valve) like mentioned. But I would run a compression and leak down test to rule out any issues with the cylinders, pistons, or head gasket. If everything checks out, I would suspect the valve stem seals.

Ya it broke at a dyno shop in waukesha. My PCV system is stock going to a catch can with the check valve would have been a good idea but its losing so much oil i think its past that bandaid fix.

guess you should know the entirety of what happened and whats going on. so: when it ran on the dyno it had 220WHP on 880pte injectors, big 16g turbo, 2gmaf, injen air intake, walboro fuel pump, stock intake manifold.

The dyno shop has informed me it has less than good compression but runable they didnt give specifics, but it has a cel still for my barometer a previous unresolved problem ive had. also, the isc has a -.16v (idk how thats possible ha) according to this shop and its not idling correcting(it was before i dropped it off). can the bliss be manually adjusted with grounding on ecm link? they shouldnt have tuned it with a cel and all of those issues thats probably why it broke. they were supposed to look at my cel and fix that first. instead they jsut threw it on the dyno didnt reallty change anything but make it run less rich and charged me $500.

End result im thinking about just swapping motors with my friend and hel rebuild this one. it probably just needs a rebuilt head. so because of these plans i guess i just want to make sure this doesnt happen to my new motor. What should i do about this shop arent they reliable for the damage that occured? sorry about all the random tidbits of info here but thanks for your help. the catch can would have been a good idea and still is a possible fix. i didnt even know about the check valve mod il be sure to add that on it makes sense.

This is the check valve I use inline of my brake booster hose and PCV hose. But like you said your issue is much bigger than this, and it's not a bandaid fix, OEM ones are just a bad design.

Good luck with the new build

so i actually got the compression test results and its 125 straight across the board. so I think im actually going to try the catch can setup. The oil could have been left over in the intercooler from my old bad turbo seals.

If it were mine I'd get the car back into my own hand, asap. From there it's just day to day operations.
-uncrimp/fix/replace dipstick tube
-disassemble the intake tract and use a solvent to clean out all the oil. lawn mower gas works great.
-replace PCV with OEM unit and add an inline check valve
-reassemble and perform blt
-if the vehicle is safe to run, let it idle or drive it to operating temperature and perform your own compression test with the engine warm and the the throttle plate wide open.
-if it doesn't[shouldn't] run, presumably due to oil all over the timing side, you'll have to do a front case/timing job on it first.
-etc.

Oh, and you'll likely be interested in picking up another bov. I'm not sure having one full of oil or running one you tried to clean would turn out very well in the end.
