Gasket Questions
I am getting ready to change a noisy lifter in my '90 YJ 4.2L. Three
questions:
1) The Haynes manual says to use Perfect Seal sealing compound on the
head gasket for the 4.2 L. I have an OEM replacement head gasket. I
thought I had read in this newsgroup that no sealer should be used with
the head gasket. Any thoughts on this?
2) From what I have been able to find, early 4.2s used a gasket that
covers both the intake and exhaust manifolds and later engines were
equipped with an intake manifold gasket only. Since I haven't gotten
things apart yet, I don't know what kind I have. If you use the full
length gasket that covers the intake and exhaust manifolds, do you still
need gasket that is for the intake manifold only. Even if the existing
gasket was the one for the intake only, would I be better off going to
the gasket that covers both?
3) I have the aluminum valve cover. Whats the best sealant to use on the
cork gasket? Is it best to put the sealer on both sides? Thin coat or
thick?
Thanks

Re: Gasket Questions
I am not sure about the head gasket sealer, I don't use any and didn't
on mine and two others and they all run good.
Is there any reason you need to change the intake or exhaust manifold
gaskets? I sure don't bother removing them just to pull off a head. I
only undo the exhaust pipe and the linkages and lift it all off
together.
I have only seen the one piece gaskets though.
I use RTV 'ultra' or sensor safe silicone and put a skim on both sides
of the cork after making the cover and edge of head spotless first.
Really spotless. I am leak free. The cork does weep enough to be damp
like it should, but no drips or runs. One big trick is to let it set
for the 24 hours it calls for a cure before breathing on the crap.

Re: Gasket Questions
I use to spray paint my head gaskets with aluminum paint, like this
article: http://www.popularhotrodding.com/tec...r_bigpicture2/
Probably more important for one piece gaskets to better slide into
place. Definitely no sealant, like the Permatex Silicone you'll probably
be using on your valve cover.

Re: Gasket Questions
I also have a 93 yj with the 4.0 with a noisy lifter, my question is: will
the lifters come out without removing the cylinder head? My factory manual
claims it can be done both ways, true??
