Sealing a head gasket
I recently replaced the head gasket on my 1952 cub. Since I replaced it I have anti-freeze seeping around the gasket. I torqued the head to 45 ft lbs, based on information from my IT manual. Any suggestions for getting it to seal other then trying Bars Leak?

Re: Sealing a head gasket
Did you seal the bolts when you reinstalled the head?

Re: Sealing a head gasket
What are you sealing the bolts with? I have looked for copper spray, but my local parts store didn't have any.

Re: Sealing a head gasket
I used Permatex Copper Spray-A-Gasket on my Super A. Didn't use any thread sealant. Tractor Supply has it. I'm, surprised autoparts stores don't have it or an equivalent. Did you re-torque after getting the tractor to operating temp.?
I also used this stuff on all of the gaskets around the engine. Water inlet/outlet, timing cover, manifold.

So, just to get this right, are you applying the teflon based pipe sealant just to the threaded part of the headbolts before inserting them into the head to tighten?
And the copper spray is used on both sides of the head gasket before setting it down to seal the head, this is used like the indan head gasket stuff?

Re: Sealing a head gasket
Torque is 65lbs. Work your way out from the center bolts as you torque. I like to go to 40lbs first then to 55lbs then to 65lbs. I use a hi tac spray gasket sealer. I dip my head bolt threads in a can of number 2 permatex. You must wire wheel your head bolts first to remove the old sealant.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Re: Sealing a head gasket
Service Manual GSS-1411, which is available for download on this site, has all the torque info for the whole tractor, and has the correct tightening order for the head.
If you can't get one locally, a good torque wrench can be had online, get one that will do up to 100 lbs.

Hi,
Here is a page from the Cub service manual, GSS-1411 showing the head bolt torque, and the head bolt tightening diagram.
