Re: head gasket ?

I got lucky when l replaced my gasket last year. I only broke one head bolt. Tried the left handed drillbits, no luck. My problem was that the head of the bolt snapped at the head. Had to drill the bolt through the head to get the head off (the shaft of the bolt was "rusted" into the hole. Once the head was removed l drilled the bolt in the block using a slightly smaller bit, then chsed the threads with a tap.
When l put it all back together everything tightened down, so l must not have messed it up too bad. Used a good thread sealer, and tighten in increments. Good luck. Hutch
Why is there never enough time to do the job right, but always enough time to do it over. :?:

I think the first " head " i ever removed , was on a rust bucket that had been in the weather for decades . every head bolt slipped right out like butter :!: I ( naively ) thought "whats the big deal with head bolts ", nothing to it . :oops: coppersmythe..........................

remember now to flush the block out as all the shavings will get in the cooling system and your new radiator

Hi,
The head bolt threads need sealer put on them, they go into the engine water jacket.
Some of the people on here spray the new head gasket with sealer also.
Below is a post I wrote on, with info, and pics of the sealer products. It's at my 1st post on the page.

viewtopic.php?f=1&t=102173&p=807849

Below is a page from the Cub service manual with the head bolt torque sequence, if you don't have it.

http://www.farmallcub.info/manuals/gss- ... 001-14.jpg

The head bolts should be re torqued after the engine has been used, and has warmed up fully, and cooled down 1 or more times. Re torque them when the engine is cold. :)

after i rebuilt the engine in my '52 i ran it 15-20 minutes a day before i went to bed to adjust this, tune that, figure this bit out... you know governor, belts, regulator, carb.... and then it sat for a week and i found a single drip on the floor under the carb. it was green. i pulled off the rubber air pipe and more green came out. pulled the manifold and found green at the #4 exhaust port. pulled the plug and looked in and found green sitting on the #4 exhaust valve. pulled the hood (getting good at that) and pulled the head, but with so little time on the engine i didn't see any signs of leakage. i took measurements on the top of the block and it was flat to within a thou or so, but when i put my straight edge on the head i found 9 thou through the center between #2 and #3. hadn't overheated since i had it, not sure what happened, maybe there was so much gunk in the cooling passages it filled the leak before I got it? who knows. Anyway, i took a 1'x3' piece of 1/2" plate glass i made into a table 25 years ago and spray glued 3 pieces of 80 grit sand paper to it and started to rub the head back and forth. every so often stopping to look at the surface and make measurements. Stopping every so often to change sheets of sand paper. Approximately 3400 strokes back and forth later my warp was less than .001 but more than .0005 with my feeler gauges. new head gasket, extra copper coat, made sure to indian varnish the head bolts and haven't looked back since!
