No boost and buzzing noise after head gaskets?
Ok. So last night I FINALLY finished putting my truck back together. Long story short, I had a #3 balance fault that ended up being a smoked piston. SO, while I had it torn down that far I figure I'd start the bullet-proofing. ARP head studs, EGR delete and a 4" turbo back straight pipe.
I say FINALLY because the last time I drove my truck was in June. Prior to this I'd never done more that an oil change or an alternator on a vehicle so there was obviously a learning curve and I didn't have all the money to just knock this out in a weekend or something.
Anyway, everything is back together (minus a few AC lines and such) and my turbo sounds like crap and has almost no boost. In stead of a nice clean whistle, it makes a really rough sounding screach. Almost like a loose belt on older cars. It's also popping a P2262 Turbo charger boost pressure not detected - mechanical.
It seems to get slightly better as it the engine gets up to temp. I don't have a piro so I can't tell you what the EGTs are doing.
Now, one thing I know for a fact, is that my left exhaust manifold to Y-pipe connection is not as tight as it could be but if there's any leaking it's very minimal.
My thought is this sounds like maybe the veins are probably siezed because the truck sat for so long, but I wanted to get your guys' take.
OH, also, there is a pretty loud constant buzzing from the engine bay now. It starts as soon as I put the key to the On position so I know it's electrical. Kinda makes my interior lighting fluctuate a little while I'm idling in park.
And lastly, a huge thank you to everyone on this site, and the site administrators for all the help and info. This site is a fantastic resource and I would not have been able get my truck back on the road without you guys!
