Is permatex ultra copper good for LIM end seals or is something better (permatex ultra gray or blue).

Permatex ultra copper has the best temp performance but do not know if it is doing this at the sacrifice of something else (sensor safe?)?

I personally used the black RTV stuff as that is what came with the gasket kit (Felpro). I made sure to let it set up for a day or two before refilling the car with coolant.

I used blue RTV when I did my LIM gaskets, and it was a matter of just a couple hours before I refilled and had it running again.

On the video posted here they put a dab in the corners, then laid the ends down, then laid in the lim gaskets on each side, then laid another dab in each corner in the crevice on top of end seals and lim gaskets at the corners again.

Rtv in corners, end seals and gaskets in then another dab in the corner crevice.

Sound ok or is that a bit over kill with the rtv.

Maybe just lay the end seals and gaskets in then a dab in each corner crevice or is the "rtv sandwich" ok. I don't have things apart yet but from what I can tell looks like factory did an rtv sandwich in the corners

Regards.

My dad's been a mechanic for about 30 yrs and he swears by it too.

About any RTV will work for that application. I used this my first time since it's sensor safe and I didn't want any issues:

I've still got it and use it for a variety of things. My second time through the LIM install I used this since I was sealing up parts of the exhaust too and wanted something that would handle it.

Technique for laying RTV in corners. Sandwich in the corners per video or just lay gaskets in then a bead in the crevice. Should I have a wee bit under each in the corner.

If you look at my guide, I recommend a little bead above and below the joints. Lay a small glob down (pea size or smaller), lay your gaskets, then put another pea size glob on top. Lay the LIM.

Thanks Saberwings & others! Great write up just was not clear on how much rtv in the corners and couldn't tell excactly from pictures. I dont want to go through all the work and have a failure do to such a small thing (rtv in corners) not being done right. If I tackle this I will let the rtv sit a while (24hrs or better) before firing up.

Still waiting for my oil analysis and to see if my reservoir make a slight drop again but have not been driving very far recently.

Thanks

The "'great stuff' sounds like an excellent product, 5min work time though? Assume thats 5 min to get the intake laid on then can do the bolts as the weight of the manifold will be doing most of the compression.

I used the black RTV from permatec

As for applying. I put the gaskets on, put the pushrods in then rockers. Once I was ready to put the intake down, I lifted the gasket and put a small amount under the gasket. Then large dabs in the corners and a good size bead connecting them.

Sealed mine. It's been two weeks and no leaks.

I suggest the Right Stuff. . . I used it many times before and it is far superior to RTV. A bit more expensive though.
