I had recently taken my car to the dealer ship Bc my car is burning oil. Its not smoking on start up it will however on acceleration. The compression test came back good. They had told me my supercharger bypass valve is causing the burning of oil and they told me its dumping out of the PCV due to too much pressure bc it isnt opening up? I need help figuring out whats causing my car to burn oil .

 

bypass it.

 

How much oil is it burning? How many quarts came out at last change?

inspect your throttle body - is it covered in oil?

Bad piston rings or bad valve stem seals could also be the cause.

 

IF the valve seals and or guides and or rings where bad wouldn't that show up in the compression test? It seems like Im burning a half a qt a week i do drive over a hour a day. I will check the throttle body today and record my results. @ lawless what do you mean bypass it? Would a catch Can help with this?

also it is barely even smoking out the exhaust it is very minimal

 

Not necessarily. A leak down test would give you much better results.
That's quite a bit of oil to be burning.
Look up a sc bypass mod.
A catch can would help keep oil out of the intake tract. But it WILL NOT ACTUALLY SOLVE THE PROBLEM.

 

they said they did a leak down test as well

 

And what were the results..

 

They said the bypass is causing you to burn oil... Never go back there again unless it's to tell them they need a new profession.

 

They said they had to replace the Bypass to further investigate. also would the excess pressure be whats causing my dip stick to pop out between drives? what are and where can i find bypass mods?

 

Yes that would cause the dip stick to spit out

Don't even worry about the bypass because it's not your problem. You need to have someone with a brain do a leak down on the car

 

when they told my me the bypass was causing that much oil consumption i was thinking the same thing makes me wonder if they half ass'ed the compression and leak down test not to mention they are $ 90 labor

 

what all do they look for in a leak down tests? and how is it performed

 

To find out where the oil is getting Into the cylinders. And google it. Or YouTube it

Put air in to cylinder, it comes out somewhere. You fix what's leaking

 

i have the written results on compression tests somewhere i will put it in here later ..

 

Compression tests won't tell us everything.

Get a leak down done.

And who knows if the compression numbers are even right since they're dicking you already

 

right so if was leaking somewhere would explain the pressure popping out the dipstick

 

Yes. It's probably your rings. PROBABLY. IT could be many other things though. But a leak down will tell you

 

correction what would explain the pressure issue

 

Excessive crankcase pressure. Due to bad rings. Which could be why your getting oil into the cylinders and burning ir

 

This.
