Locktight on Rocker Arm Botls?
Locktight on Rocker Arm Botls? I was reading on ls1howto, and it sudgests putting locktight on the rocker arm bolts if your heads are ported and polished. Any truth to this?

ah, not. you need to use thread sealer if the heads are ported and expose the intake rocker bolt hole inside the runner. otherwise you could end up injesting oil, or vac. leaks.
Yes; no need to put it on the exhaust rocker bolts, just intake side. I used loctite thread sealer (looks green), or you can use permatex thread sealer.

loctite will NOT work on rocker bolts... trust me... ive gone through this problem 6 times now...
the only thing that works so far is indian head shellac compound.. its a thread sealer and worked perfectly on my engine.. i tried blue locktite, red locktite, RTV, mix of blue/rtv, mix of red/rtv.... hahah nothing worked except the shellac

Verdad Gallardo The loctite sealed mine up fine, but the threads in both the head and the bolt must be perfectly clean. Second time use in the same threads, Permatex also recommends the use of another pretreatment on the threads.

with loctite it definately worked on some of the bolts... but certain cylinders were still getting oily when i took my manifold off. Manifold is now bone dry now that i used the shellac compound.
Its funny you should mention this, my dad used it a lot and I have an old old bottle of it in my shop. Not sure too many people use it anymore. Also not too many people properly prepare the threads for loctite either for that matter.

napa carries the shellac btw. works super well and is pretty much dummy proof
