Default Aluminum LIM gaskets for 94?

Does anyone know if they make the aluminum LIM gaskets for the 94 SE?

I searched the forum and couldn't find anyone referencing them. I found someone with a link to the 96-08 versions:

Thanks!

Drats. I redid my lower intake gaskets back a month or so ago, but a shop told me I was leaking from there. I haven't had a chance to look at it yet, but I'm not entirely convinced they didn't just see the dirt from when it was leaking.

I did run into a problem where these had to sit half torqued overnight because I sheared a tool doing other work. So I'm debating whether it just didn't seal up properly or if the intake is actually pitted and therefore will never seal right. How often do these get so pitted they can't be fixed?

I saw on the BC forum writeup for doing LIM, the author used silicon under and on top of the gasket strip on each side. I had put the little glob in each corners, but did not do the side. Is this recommended? I know the gaskets say do not use sealant, but this side strip does seem to be made of a different material.

I don't recommend sealant on the gaskets, unless you have exceptional pitting etc. Did you seal your bolts that hold the LIM down?

I don't think sitting half torqued would effect them at all.

I used some of the red RTV on the bolts. Did not use any loctite or similar to make sure they didn't vibrate loose.

The spot the mechanic identified was on the flat side rail, which he put RTV on the exterior to attempt to seal it. So it'* now near impossible to see what is actually going on without scraping it off.

Is oil pressure normally this high? I took this after it actually dropped a little. It was halfway between the last tick and 120 (my guess is around 100 psi?). This was with outside temperature around 60-65, so it'* not from cold weather.



After about ten minutes it drops to around 40 psi. Then after driving for a while when I'm idling the needle bounces a little, my guess is the bouncing is from the intake leak which is only apparent on a hot engine.

Anyway, do I need to check my oil pressure relief valve? Is the fact that it is holding this high of pressure a good sign that the engine bearings are in decent shape? The gauge was replaced a couple years ago, so I would expect the gauge is reading accurately.

Excuse me, to clarify:

By replacing gauge I meant I replaced the Oil Pressure Switch
