Hi

Hope some can give me some tips.

I have installed a new exhaustmanifold with new gaskets ( about 10k miles ago) but the gaskets are startign to leak ( loss of power) .

would be easy enough to replace them ( or use same ? ) but are there any tips on making sure they are staying tight ? ( additional sealer maybe)

A exhaustbrake is installed !

thanks in advance

 

i dont have the P/N in front of me but there is a multi-layer gasket for these motors that will seal 99% of the time.
i guess i dont get what youre saying though, did the bolts come lose or are the gaskets just leaking?
if the bolts came lose, tighten them up and call it good, it the gaskets are leaking, replace them accordingly

 

I second the ML gaskets, they are more money but worth it.

 

thanks for the feedback

any hint on where to find those ML gaskets ? is it still advisable to add extra sealant to it and if so which would one recommend .


btw the bolts did not come loose nor is there black sout around (yet) but several ( 3) do leak almost all around ( detergent test). kind of hinted me to it as I felt less power ( and more/longer smoke)
