i know this sounds bad, this is my first heavily modded car, and boosted car.
what do you mean it bleeds boost like crazy.
and by scanning it.. with a scan tool? like the Modis from Snap On or what? i hooked up the Modis at school before when i was looking at two codes i had, one was for my ECT and MAP, the ECT sensor was cracked, i fixed that, the MAP sensor was completely gone, the guy before me didnt put it back on...
didnt get a chance to get the MAP sensor hooked up and the vac lines fixed before the car started puking coolant down the back of the engine, and not staying started under a load, i never even gave it half thottle bc its a fresh rebuilt engine, letting it break in.
its got a busted head gasket on the firewall side of the engine.
when i looked at PID data in the scan tool it showed can is running lean, it has a vac leak where the EGR bolts to the LIM, bc the previous owner stripped the bolt hole there. i got to re-thread that for sure. during the top end rebuild im about to do.(valve job, surface the heads, valve seals, replace what needs to be)
i work at a engine shop, so i get to do all this for free.
gasket set is gonna bust my ass though, even with the company discount.
