Exhaust manifold bolts

[coolrider2112]

Hey guys I finally think I know why I'm bogging at WOT int he higher RPM range, I decides to just replace the exhaust manifold gasket and noticed that 3 of the 4 bolts that connect to the turbo from the manifold we pretty loose, im talkin loose enough to wear I barely had to put press on the bolt and it turned easily. Wouldnt this be my cause of bogging at higher RPM? 1 bolt is still in because the dang thing is so tight in there so I sprayed PB blaster on it and gonna attempt at it tomorrow. Just let me know guys, thank you.

So try to tighten the bolts and post back..I don't know why you didn't do that in the first place and then make a thread about it..

This.

If there is a bolt lose, tighten it. Process of elimination is the best. Once you've tried everything you can think of and still doesn't fix your bogging problem, then come back and search. If you can't find your answer by searching, post a thread.

I was asking a question if it could be the bogging problem, obviously if I knew I wouldnt post, and I guess you dont read what the site posted about replies, "dont reply to a forum with "look in the search", so enough negativity if you going to down someone that is just asking something then just dont reply, thank you...

Yes a pre-turbo exhaust leak can cause your symptoms.

Don't forget anti-seize on your studs, and make sure to use a torque wrench where at all possible. It's very easy to over tighten these nuts to where you pull the threads out of the head as it's aluminum. The torque spec is pretty low (I want to say 12 ft.lbs.).
