Thread: quick help on LIM

I am doing th elower intake manifold gasket again. I used thread sealer last time but alldata says use thread locker. I am in the middle of this and I don't have a lot of time to go searching. So could I get a quick difinitive answer on locker or sealer?

Also, supercharger bolts, I guess nothing is used on those bolts?

we talking LIM bolts right?

If it was me I wouldnt even use anything, but tighten everything down to what it should be and your fine, or just snug them up good enough if you dont got a torque wrench.

Yes, LIM

Shady places will "fix" something while breaking something else on purpose, in hopes the car gets towed back to them.
This one place ruined the engine in my buddys Malibu then he took his replacement car there and they hit all his rotors with a hammer and told him they were bad.

wrong thread guy lol.

I thought it was a drunk post

I use GM pipe sealant with PTFE. Another suitable sealant is either a permatex equivalent or a pipe sealant from home depot.

The reason to seal these bolts is because they go into oil and coolant jackets on the head. Those fluids can seep up the threads and onto the LIM itself in short time if the bolts are clean w/o anything on them.

Ask me how I know this.

Thanks Bill and I think I know how you know

What I did was use Thread sealant with PTFE on the center ones because I could see they went through to the inside of the head. Then I used thread locker on the others because I could see they just bottomed out.

There seems to be a fair amount of descrepancy on this issue from reputable sources. Everything from don't use anything, to thread sealant, to thread locker. I decided to use two of the three choices

I use god old thread tape, and my snapon on 1/4" air ratchet to tighten it up
