Low Boost & Hesitation Help!!!

[Boogieman98]

I ran the gas down to E and filled up 93 octane. All was fine until I got about half way through the first 1/4 tank and the she started to stutter, and then wouldnt boost over 10 psi. I plugged in my AP and the knock sum on cylinder 4 was going crazy. It went up to 254 and then started over a few times. I pulled over and checked the oil, and it was a quart low. I filled the oil back up and reset ECU via the AP. All was fine for about 10 minutes and then she started doing it again. I got home and started looking all over the engine bay a noticed a little oil coming out of the hose underneath the intercooler. I pulled it and a ton of oil was in intercooler. I have hit the rev limiter a few times before but not in a while.

Woah that's quite a bit of oil! I've seen a small amount, but nothing to that extent! I hope it's something small and nothing major! Interested to see what the fellas have to say on this one!

Like how hard, and for how long?

 

[Boogieman98]

Rev limiter? Well I hit it a few times when I first got it and then a time or two since then. Once was pretty hard when I was down shifting but it has been a while since then.

 

[IGOTASTi]

I think you might need a catch can.

 

[Boogieman98]

Well I got one in but have not actually hooked the hoses up.

Lol. Hook it up.

 

[Boogieman98]

Least of my worries now though. Maybe only a boost leak, maybe bad gas or maybe something more

What?! Why did you put on in there then?! :lol: Show and tell! :tup:

Too much oil being fed to the turbo? Oil loss after track is normal though. I don't see how so much oil was being pulled in, but then again, I don't have any experience with this. I want to see what the track monkeys say!

That's a lot of oil!

Clean everything out, intercooler, throttle body, etc.
Pull the plugs and check them for oil.
I would say a compression test may be a safe bet right now.

 

[Boogieman98]

How should I clean all the oil out of the intercooler? Just wipe out what I can see with a rag?

 

[IGOTASTi]

Yes, and use some carb cleaner, BUT be super careful.

 

[Boogieman98]

Ha. Super careful? Sorry I don't know what you mean. What should I not do?

 

[IGOTASTi]

That stuff will clean and eat paint if you know what I mean. Spray it on a rag then wipe. That way you won't have a chance of ruining anything.

Also as Grinder suggested I would do a compression check real quick. I think you blew past the rings at high rpm, but didn't hurt anything except oil blow by.

 

[Boogieman98]

Doing compression test right now. Not a easy task I assure you. If it is only a lot of blow by how do I fix the hesitation issue and low boost?

 

[IGOTASTi]

Once you give us compression results we can go from there.

Grinder? Lol. Is that a compliment ?

I agree that it just could be blow bye .

How did the plugs look? Oil fouled ?

May be just throwing a fit because of oil everywhere. Once it's cleaned up and the compression test done, and if the results are good, she may drive normally again. Fingers crossed.

The cylinder closet to the driver no compression. Now the question is how far can I drive it. Can I drive it to the dealer which is 30 minutes away or should I trailer it?

No. It needs to be towed to prevent any further damage.
