· Rod...from a Chrysler?
I do nothing, same as you.
No sealants, this is not the 30s and 40sI've installed a lot of head gaskets over the years but read an article recently that advised putting gasket cement on both sides of the gasket. I've never used any kind of sealer in the past and not had any problems. What do you guys do?
Never considered using that 3m weather stripping for headgaskets. Might have to try it on a certain junky high mileage engine, if I ever slap it back together.Way back several decades when I was going to college, before the days of house size loans to attend, one had rich parents, scholarships or worked your way through. I had some of the first two and a lot of the latter.
So on and off I twisted wrenches and drove truck to augment my income. One afternoon when I came to the shop there is a Chevy in my stall for a valve job. I pull the heads which are warped as is the block. The pistons have about as much side to side movement as the crankshaft has stroke. I stopped and called the boss told him what I found and that a valve job would only serve to make this exhausted engine into a massive oil burner. He said wait till he called the customer. He calls back a bit later and says the customer insists on the valve job only. You know how mechanics always pad the job to make more money? So I clean the castings, check the shot guides another call “no” the customer doesn’t want the guides fixed. So I shoot the seats and grind the valves. Dress the seats so the valves set at the same height except for the guides a primo job. Not wanting a come back do to gasket leaks I libarlly coated the gaskets with 3M door gasket adhesive and put it together. Gone for several nights this damn thing shows up in my bay a few days later the customer now understands the Root Problem isn’t going to be solved with a valve job and has bought a major rebuild. So I got to tear the heads I so excessively glued to the block off again. By now the 3M was baked to everything which took hours to get the heads separated from the block without adding more surface damage than what was already there. Sometimes you can’t win for losing.
