Seeing oil seeping from head bolt.
Posted 19 August 2014 - 02:13 PM
This a head gasket issue?? If so who is a good source for gaskets for these??
I am not so sure its just a loose bolt, but suppose that is also a possibility

I like the two part copper or aluminum and heat resistant material gaskets. They are a little thicker than just aluminum or copper, but they squish nice and create a great seal.
That said, I can't find them online right now. Here's a source for plain copper:

I had that problem before.. I kind of ignored it at first..
After changing cylinders (I had a piston burn) I still had it... After a while I got a new head (which also solved the problem with a few broken fins), then it stopped..
I'm unsure where the oil came from...
Kind of early K750.
Dnepr K750 1956 (it says on the polish papers, damn lies! must be from the 60's)

Anyway oil is only coming from one bolt. Anybody have the head torque spec for a K750 or MT12 motor??
I haven't found an English manual for mine yet.

I reckon 11 foot pounds is too loose.
I had a similar problem with my M72 which is very similar and actually has k750 heads fitted and I did mine at 40 foot pounds.
The recomendation I got on the forum was 32 nm which is about 42 foot pounds so I'm pretty confident its about right - All running fine at the moment.

Yeah the 11.6lbs seems a bit light, but I figured I would start there then ask rather than crushing the new gaskets
Thanks a bunch.
