Blocking coolant passages in blower case

[DanJ]

So i picked up a Ron V ported case from Ilikebmx and it had the coolant holes blocked with some sort of clear RTV looking stuff. It looked a little old so I'm looking to replace whatever goop was used to seal them in the first place. What should i use peanut butter, clear RTV, some other stuff i am not thinking of?

Mine have regular black RTV, weather that is OK or not is up for debate..... just make sure to clearance the passage in the LIM to get the coolant to the back head that you are blocking w/ the blocked blower passages

I was seriously asking regardless of the peanut butter comment.

Clearance? do you mean with the gasket material? I don't even know if it is that beneficial to block them in the first place. Looking for some advice.

Ohhh ok, so that's behind that cap on the end, shouldn't be a problem. So what do i use to block the coolant passages?

 

[Bob Kazamakis]

i had it blocked cause i was going to be running an ls1 TB and i hate when the coolant fucks up the gaskets. you can tap the holes in the LIM with pipe fittings. thats what i did on the other LIM that i left on the car.

 

[DanJ]

Hmmm that's a good idea. But is it beneficial to have them blocked in the first place on a stock tb setup?

 

[Bob Kazamakis]

eh i dont know...i plan on leaving it for the wrx. people say it helps and it seems like a popular thing regardless of the type of car you have. i know James says that the TB passage does feed coolant to the back head which is why he suggests cutting the divider a touch like the picture above. if your not pulling the TB or supercharger anytime soon then i'd personally just leave it. if you plan on having it off then i'd block it.

 

[DanJ]

I think ill give the pipe fitting plugs a shot and notch that seperator. They have a tap for pipe fittings?

 

[Bob Kazamakis]

yep NPT tap. they're taper fit. i'd bring the LIM to ace and find an NPT plug that fits and the corresponding tap for it. careful on the depth of your tap though as the holes arent very thick and if you go to far they will fall through (if that makes sense?)

 

[DanJ]

I looked at the LIM and it makes sense. If those are plugged i really don't have to worry about those o rings then do i...

 

[Bob Kazamakis]

nope. i just threw a little black rtv on them just to be safe oh and also on the threads.

Dan - I started blocking the coolant passages on an intake today. I bought (2) 1/4" NPT flush plugs at TruValue. To thread them you need open up the holes with a 7/16" drill bit and then use a 1/4"-18 NPT tap. Unfortunately my set did not have a 1/4-18 tap. I need to go get one tomorrow, but I can tell that they will fit. HTH.

Mine:

And a Pick of my blower(back when it was clean).... see the blocked coolant passage??

 

[DanJ]

Weird, your coolant passage looks quite different than mine did even stock...

My coolant passage now looks a lot like the one Tommy posted and the holes to the blower look like GTPMikes. GTPMike's looks like set screws and that worries me a bit. Are you not concerned with them coming loose and ending up lodged in a coolant passage somewhere?

It was most likely tapped, sealant on the screws, then physicaly screwed in.

 

[DanJ]

I just talked to him. They are the npt plugs tommy is talking about.

 

[TommyGloves]

I put red loc-tite on those NPT plugs. They ain't going no where.

 

[DanJ]

What dept were those in?

What dept were those in?

Just look for the various brass fittings in the plumbing dept. They should be somewhere in that vicinity.

Finally got this thing done. Had to go to a plumbing supply company to find the plugs though.
