head gasket seal

Anonymous-0 · Dec 12, 2011

assembled and retorqued my Farmall Super M head, started it up and ran for maybe 15 mins and noticed a very small anitfreeze weep. Could this correct itself? or should I not run the tractor anymore, and get a new head gasket?

I don"t know what you define as a "very small" weep, but a "very small" weep as I define it would not make me want to remove and re-gasket the head right away.

I would be more inclined to let it go for awhile and keep an eye on it to see if it gets better or worse.

Did you use sealant on the gasket?

did not use sealant. It is not an outright leak, that I can see. More of a bit weepy. I will run it again and see what happens.

I think I would retorque the head bolts before getting too excited. What torque setting did you use?

There are a lot of assumptions that have to be made -

Assuming you torqued in the right order,
and you oiled the threads before torquing.
and torqued up incrementally to the full torque...

Was the head checked for flatness? I'm assuming no since you didn't mention it.

I'd recheck the torque on the bolts and watch it for a while.

If it's still leaking and you DO end up taking the head back off, I'd have it checked for flatness just to be sure.

All I have seen (not that many) say "use sealer" on the gasket. It is always a good idea.

Too add,

If the leak is EXTERNAL ONLY= less critical.

If it is also making it into the oil pan INTERNALLY,MAJOR critical!!! It is very destructive to bearings!

Be careful running it too long.

I just had the same issue with a Cub. The "weep" corrected itself after the engine had been run a bit. If it had continued I was going to put a couple of cans of PET milk in the radiator. No joke it works. Best sealant I've ever used.

I would do a cyl pressure leak test to see if it is leaking internally. It has become more and more of a problem it seems with the sleeve flange height being too high with all the aftermarket sleeves. If you look at the shape of the head gasket you will note it follows the contour of the combustion chamber, not the sleeve flange, so there fore it crosses the flange in four spots and will leave a gap too large for gasket to compress if sleeve flange is too high.I personally like them to be no more than .002 but .004 should work. Friend had a 300 last year, had .008 and it leaked immediately. A pressure test will give you peace of mind if it checks ok or tell you tear down is needed.
