So just as show seaon finishes for the winter i get a noisey ticking sound from the engine - yup exhaust manifold gasket has blown
So new gasket and new brass nuts purchased ( old nuts stripped off when removed)

Manifold off - cleaned /scraped old gasket off - fitted new one and tightened up nuts

All seemed ok but lessthan 2miles now its blowing again - tightend nuts some more but still blowing from top middle

Face off manifoled is a bit pitted but not too bad(or so i thought)

So my question is -----
Do i try tightening the nuts some more - scared that i might strip nuts or worse snap the bolts?
Fit two gaskets?
Use a belt sander on the manifold to get rid of pitting?
Or a more sensible suggestion?

Thanks

Go easy on the studs/nuts. A machine shop can plane your exhaust gasket surface so nice you won't believe it. You'll never fix it again after that. You don't want to snap off a stud------- John

I agree with Oilleaker re the machine shop instead of the belt sander (shudder-shudder), but the correct torque for the intake manifold is 15-20 foot/lbs, and 35-40 for the exhaust manifold (per Chiltons repair manual). Were you aggressive enough?

For those of you with M38's and MB's be sure machine the surfaces of both the intake and exhaust together as a set.

Ok - found a local auto shop who were willing and able
Cost £40
Looking to try and fit it today (got a torque wrench too)

With regards the gaskets , do the metal rings insert into engine block or the manifold ? Manual says insert into exhaust port which I'm assuming is the engine block -
They are a v tight fit into engine block but just drop into manifold

Thanks

I put mine into the exhaust manifold because they wouldn't fit into the block. Have not had any problems. John
