Hello,
I blowed up my gasket between the cylinder head and barrel.
There are problems with the cylinder bolts. The threaded holes are too big.
Can I use bolts M10x1 to solve the problem?
Or is there an oversize for the bolts?
What is the best solution?

Is the gasket in solid copper an option?

Hi Richard...Cylinder head bolt threads are 3/8" BSF...The best solution if they are worn/stripped is to fit helicoil inserts to restore the threads to the correct size...

A solid copper head gasket is a 'must have' item as the modern composite gaskets are unreliable.
TT John from this site has had some made and has them for sale... Jomichael@aol.com ....Ian

Hello Ian,
Thanks for your quick replay.
What must be the thinkness of the solid copper gasket?
Maybe I have someting in the garage.

Those helicoil are easy to find?

Richard
