Thread: zzp intercooler

Zooomer was very quick to reply.

"We actually had a bit of debate about this in the shop. The small passage was approved by me, overruled by others here. We ended up building one and testing vacuum. We decided from the vac #'s that it would be ok and have been using them for over a year.You ahve to be very careful not to get RTV in the passage though."

I've had to redo Garlock installs 4 times now, they were all an oily mess. And yes, all installed used RTV... Ultra Copper on 2 and Right Stuff on the other 2. I have yet to have a stock S/C gasket have an oily mess problem with RTV used.

Stock or Felpro L67 Gaskets FTW win w/ Ultra Copper IMO.

Actully, I'm really liking the OEM L32 gaskets. On ridding my car of Garlocks I used and modified an L32 for the lower, and the upper I modifed an L67. The install went smooth and clean, i'm real happy how it turned out. I used Ultra Copper on all sides too. I wish I could of used an L32 for the top but unfortuneitly it wouldn't quite fit with a GEN 3.

Only compliment I'll give for the Garlocks is that there easy to remove, so at least uninstalling them and going back to stock isn't as painless.

If you go with the L32 gaskets and use a demel to do the trimming. Please use safety glasses and a snug mask.

Trimming the OEM L67's is fairly easy with a razor blade but would likely give a more smooth edge with an exacto knife. Try to keep the important edges smooth.

I marked my L32s but didn't trim or use them. I trimmed the L67 ones but since the edges were no longer tightly molded like designed, I felt they would soak oil. This along with the good condition of my Garlocks in the past was the reason I used them again. It may bite me this time around, and if it does I'll give my trimmed L67 a shot.

If using the GM pump, make sure it is the lowest point on your system, because it has to be primed. Bottom line, if you are mounting the pump and it's a little higher that the lower FMHE radiator hose, temporarily let the pump hang low until you've ran it and the system is flowing well, then mount it.

Good advice. A cut off wheel would make cutting the L32s simple for sure. I ended up using some utility scissors which are super sharpe and cut metal well. I used these for the L32 and L67 gaskets, although the workout was done on the L32 for sure. :-) LOL. I wish GM would release an L32 style in the L67 form, That would kick ass and beat anything currently availible, I', impressed with the L32 gasket.

Damn right! I made this mistake when doing my IC the first time around. I mounted mine low but it wasn't at the absolute lowest. Basically I had it mounted on the bottom of that shelf where the PCM/Airbox mounts on in the fenderwell. I couldn't get it to prime to save my life, so all I did was relocated it down in the fenderwell and mounted it on the splash shield which was inline with the lower most fitting on the IC radiator. After that change the pump primed quickly and has worked well ever since. So yeah, the absolute lowest, the better no doubt.

Because of the type of pump the GM one is, it really needs to the at the lowest point of the total IC system. Mine was mounted a couple of inches higher than the lowest point. The pump was running but not pumping. As soon as I took it off of it's mount and it dropped to the absolute lowest point, the fluid all disappeared from the reservior, fluid made it to the pump thus priming and started it pumping. I filled the reservior back up, and mounted the pump in the fenderwell again and all is fine now the thatsystem is full.

ohh ok thanks!
