massive backfire maybe?

 

Oh sweet - a new Maxim!

 

i just got it in the mail

 

really i got that issue last month

 

well i just got a new subscription so they are probably sending me the last issue

 

Damm pain in da a$$ spot! ( talking about gasket...lol)

 

24 pages of the hottest models on earth!?!?!

You mind scanning those pages please.

 

i had to take the engine out to get to it easily

 

+1 on the backfire theory. Did you notice a change in the exhaust note recently? Possibly pushing raw fuel through the system for some reason, causing it to ignite down by the turbos - I've read about this with anti-lag settings for turbos.

 

Check the manifold or header for straightness. Do the same with the head. Lay a flat edge along it and make sure they are both perfectly square. A backfire should not do this if everything is tight and flat. Turbo manifolds and headers see an extreme amount of heat and therefore can warp very easily. Check it before it goes back together.

 

ill check for warpage but I believe it was because the nut backed off the stud, when I took the engine out the nut was almost completely off of the stud

 

ya that could be a problem. Good luck with the repairs

 

as above, loose studs/nuts that cause exhaust gas to go between the manifold and head is a very common cause of gasket burnout.

 

for the dumb ones here....that is the exhaust manifold gasket?

 

yes it is the one that goes between the turbo manifold and head

anyone have a good solution to keep the nut from backing out again? I would use loctite but its only rated to 450 degrees

Ouch. Doubt if you could have found a worst spot. Sorry.

 

The only place I can find that high temp loctite is Fastenal and they want $150 for a 300 gram tube of it. Any idea how high temp that threebond is rated

 

My builder (SG-Motorsports) is going to use Nord locks. My APS TT was originally installed without taking the eng. out by another shop and every single nut was loose, one was missing entirley.
