Hello everyone, hope the holidays have been good to you all.

Right now I am in the removal phase of a LIM gasket change. My 93 is leaking coolant from the area underneath the throttle body, onto the trans and onto the ground. Everyday there is a fresh puddle, so i thought it time to fix it before it got worse. Oil looks good so im pretty sure it'* not getting sucked in.

3 questions:

1. I bought gaskets, TB, plenum, LIM, and thermostat, and fuel injector o-rings. ARE these all the gaskets ill need?



2. I asked the guy at napa which thread lock i need to use (shop manual says to use it). He didnt seem to know, he pointed and recommended either the red strength(high) or green (medium). Is this what i should be using? And if i use threadlock do i have to apply more than the recommended torque?



3. The LIM gasket set came with a stick of RTV. Will this be enough to complete the task? will i use it only on the LIM gasket, or should i use it elsewhere as well?



Any input is welcome Thank you.

All this advice comes from a Series 2 standpoint, so pardon if any of it does not apply to Series 1...

You only need a few dabs of RTV, so you'll be OK with what'* provided.

The red threadlocker should be OK for UIM bolts and such...but I prefer blue "medium" strength for TB and fuel rail nuts, just because you may have to remove them again someday (for cleaning, etc.), and blue'* mush easier to "break" than red.

I'd also advise some white PTFE thread sealant for things like the ECT sensor.

I'd say you might as well get a new thermostat and a thermostat seal (rubber ring that goes on T-stat), also.

And, do be prepared to change your oil shortly after doing this job.

Plus, do you have a good torque wrench?

hello agrazela, thanks for the info on the threadlock and rtv. A new thermostat sounds like a good idea. Yes i do have a decent torque wrench that ive used many times befrore which i believe to be accurate.

I was lucky enough to attend a threadlock seminar,my last semester of college(october 2007), that was from a loctite representative. He said that he didnt recomend the use of the high strength thread lock on manifold jobs, because the preferred method for removing bolts with the high strength threadlock is to first heat the bolt to around 500 degrees for five minutes then to break loose. He also specifically recommended changing manifold bolts when replacing gaskets, because after a bolt is tourqued it is streched/weakened and the threads are stretched. one more little tid bit is that he said regardless of the type of threadlock being used, to use the cleaner/primer on the threads first(basically an aresol acetone), this helps to clean the threads and it also helps the anerobic reaction to take place which hardens the loctite. and I dont know if this helps, but there is a different tourque spec when using thread lock, its called the wet tourque spec. Hope this helps in some way

Check the manual... Thread LOCK or thread SEALER? I have never used a thread locker on LIM bolts, but thread sealer for sure, so fluids don't wick up the bolts.
And if you go to autozone or the like, and ask for "thread sealer" you will either get the deer in the headlights look, or you get steered to the thread locker again.
I've never had a LIM bolt get loose, but I've had them leak... so check to see exactly what the manual says to use.
