Thread: 300Tdi MLS bolt tension and TSB

Whether or not it is recomended i do not know. But I gave mine the extra 20degrees to cope with extra boost.
So no its not going to solve the oil weeping we are experiencing.

Mines going to get a coat of hylomar or some copper spray

Everything I read at the time indicated that it should be fine IF the deck and head are perfectly flat. So despite my best efforts this must not be the case.

I think that should do the trick. Please let us know the result.

Mines not going to be perfect as I have no intention to get the head milled again but will take a few pics as I go and see what happens. Hardest part is its here at work and I'm doing it between other jobs like this karmen gia that's just rocked up

MLS (laminated ) head gaskets should not be used with Hylomar or any other sealant, clean dry surfaces and factory torque tolerances.
Victor Rienz MLS head gaskets are used on everything from race cars to heavy duty trucks.
I used one on my Disco 300 tdi, which had a warped head (7 thou) between cylinders 2 & 3 after blowing 3 composite Elring composite head gaskets, it lasted nearly 3 years and was only replaced (still in perfect condition) when I purchased a new head.
I can tell you this, if you use any sealant with a laminated gasket it will fail and if you over torque it will also fail, Regards Frank.

As Frank said, I've always been told scrupulously clean and dead flat.

I used white spirits and then methyl ethyl ketone, the only time I've cleaned more with MEK was bonding aluminium on race cars.

Cleanliness was not the issue, i am confident of that.

Thanks for the heads up re over torque, that could become a costly oversight. Too late now, see how it goes in time i guess.
