Head gasket a little bit tighter?
The head gasket on my '53 Super Wasp has developed a very minor leak towards the front of the 262 engine. There are a few drip marks that have dribbled on the side of the engine block. It's nothing too much and with over 1200 miles on the rebuilt engine, the lose of coolant probably amounts to 4 to 8 ounces (a cup) at best. I am thinking of either replacing the head gasket with a NOS one or perhaps doing the K&W Block Sealer treatment (either seems to take about the same amount of time). There's one other route I could try and that's to tighten the head down a bit more. I've torqued the head gasket to 70 lbs. cold (from 65 lbs.). Is it worth tightening the gasket, say up to 75 lbs. or more to try to prevent any more leaking? Thanks for any advice here!
