'03 exh manifold leaks...p132b

[STROKER_T]

mornin'...got an '03 here with 160,000 miles with a reoccuring p132b code,found exhaust leak at #7 cylinder at exh manifold...funny thing is that the VGT learn pid reads yes with 27 learned events..

was wondering what y'alls opinion is on using exh manifold gaskets...i personally have never used 'em,figure they would come stock if they were that good...

i gave the customer the option of having them machined flat vs. replacing them,it may save him around $300,but i wanna do it right the first time,so i thought it would be a good post for debate...

seen a few come in with blown manifold gaskets in the past...

when i did mobile repair several years back the shop owner insisted i use that black sticky stuff on the mating surfaces of any and all manifolds,he was the boss,so i did and never had any returns from it,but wasn't sure about it nevertheless...

thanks for any opinions,greatly appreciated

The 6.0l exhaust manifold gaskets are for service once the manifold has been removed. The 6.4 uses the same gasket but comes on them from the factory. I put them on all of them without any issues and we have some of the worst cases you will ever see. As noted in pic below.

Use the gaskets, use new bolts, and make sure the manifolds are flat.

I always use gaskets every time I reinstall a manifold. I also put them on to fix leaks.

Me too! We seem to see these in runs. The picture Brad posted is noy too uncommon here in Jersey except that example looks frosted...

LOL. Depending on the time of the year many engines look that way. We recently saw one that looked like that in August. It must have been sitting around since Winter. That is always good for vehicles too.

I'm using gaskets from now on for sure...the manifold prices have dropped a bunch i think,i put new manifolds,bolts,spacers and gaskets on this puppy...P132b is gone,and it has power once again

 

Thanks for the advise

Always use a gasket.
