Subject: M45 Blown Head Gasket: Welcome advice and guidance, Hints and Tips

---

Dear All,

Last weekend the head gasket on my M45 engine blew between cylinder 3 and 4. (And now I have the engine apart, the head gasket between 1 & 2 does not great either!).

The engine has run less than 5000 miles since a new block and a skimmed head were built back into my reconditioned engine.

The cylinder diameters are at 88.9mm.

I plan to skim the head again, as it has been somewhat eroded during this recent episode, but the block looks OK

I would welcome any Advice and Guidance, Hints and Tips, Do's and Don'ts etc. for my rebuild.

For instance: Should I use a copper gasket (as from the LOC), a composite gasket (as from LMB), a solid copper gasket available locally or what? Any jointing material or dry? Torque loading? etc, etc.

Welcome any and all suggestions either via the Forum or please call me direct on + 44 (0) 1590 677 900 and I will return your call. Any time.

Or email me: andrew@cheyne.net

I am looking forward to hearing from you.
