leak down test i stil think those numbers are to high for it to be blowm

 

Leak down test? What is that...lol

 

well i dont even think you'll need to do one i mean if it was a fried ring or landing compression wouldn't be 160. hell last time i checked on all data spec was lower then that. try to find a temp gun and point it at each exhaust port, see if 3 is substantially cooler then the others

 

Alright i'll give that a shot. I'll see if my friends have any.

 

cool cause when i got my car something similar happened, thought i blew it so i took it into my teachers shop did a compression test and came out with similar results did the temp gun and the temps were pretty close i believe within a couple hundred degrees at most, so i ruled that out. the blower sounded weird like it was leaking air and the car sounded like a subi, but after looking into it more, the cat was clogged it fouled out my o2 sensor and it created so much back pressure it blew my by pass valve open, and that was that. but when it was clogged it struggled to get to 5600 rpm and would only boost to 10psi after that it sounded like it was leaking real bad

 

Hmmm I dont have a cat.. i have the catless ZZP downpipe. I talked to my GM friend, and he said buy new pistons.. 180/180/160/180 is not to bad... but maybe that 3rd one is damaged? It struggles big time getting passed 5600RPM too.. but i haven't really tried hah..

 

mike! were u driving your car at dixons pub today?!

i couldda swore i saw u driving away

 

By pass valve maybe whats the most boost the car will push

 

I'll check scared too tho..

 

Quick test... 15 PSI at 4000RPM and 16 PSI at 5000RPM. then i stopped.

 

The car before she blew!! Taking it apart tomorrow!

 

Flashing CEL always means some sort of misfire.

Whether multiple or not, you will have to scan.

 

so its actually blown huh. damn shame car looks awesome
