Need Advice with Cobalt SS Blow-by!!
Got a new problem with my SS supercharged.
So i recently traded in my LS for an 07 SS supercharged.
Well it was tuned poorly from the dealer for some reason.
So i got an HP tune done on it, keeping stock timing. Also did 2.9" pulley and 60 lb injectors, step colder NGK.
So it ran great at this point, also changed the intercooler pump.
But i got a check engine light after like 50 miles.
So the tuners said they would check it out and finish the HP tune on it.
Well turns out my plugs had burnt oil, meaning there most likely is blow by causing the plugs to foul.
This is causing engine misfire. It is very minor, and car still runs pretty smooth and well.
Just causes the stupid light to come on.
Luckily the dealership said if i can do a compression test and tell them the numbers for each cyl, they will replace rings.
Anyone have any input on this?? Could it be something else?? I dont think it could be anything else.
The crankcase breather also is making the intake slightlyy more oily than it should, which leads me towards oil return rings.
