I am putting in a CSI pump, and I JUST bought brand new GM Seals for the crank, opti, and the waterpump. I have two questions:

First, do I even NEED to install the water pump seal, because I'm removing the water pump shaft?

Second, I installed the "plug" in the back of the pump housing, but with the water pump shaft removed, will too much oil be able to get into the timing chain area and cause any problems?

I may be worrying about nothing, but I want all my ducks in a row first...

You mean the hole in the block?

I blocked mine off with a freeze plug. I bet 90% of people leave it be. Don think it matters too much either way.

I did read a book by vizard however, where he suggested pluggin those front oil returns a little so that the lifters saw more oil on them and the cam. I think that applied more to flat tappets than hydro rollers.

where did you get your freeze plug? All I got was the freeze plug for the water pump housing which came with my CSI pump.I knew it wouldn't be a goog idea to leave the hole open in the block.

any napa or machine shop will have them make sure you use some green locktite

30thannZ28

nope, just called napa, never heard of them, nor do they sell ANY block off plates/discs. Not even generic ones. So who else?

Mike383LT1

cant beleave the napa never heard off freeze out plugs is it a corner napa or is it one of the super stores these freeze out plugs are used every day in machine shops and garages try contacting a local machine shop they should be able to help you

seriously man, I'm not trying to be difficult, but I called a napa warehouse store, and they man seemed fairly knowledgeable, and he said he has only heard of a fuel pump freeze plug. oh well, time to look in the phone book for a machine shop...
by the way, should I have used green loctite when I pushed the CSI freeze plug in the waterpump housing, because it's pretty damn snug as is???? thanks.

becareful they are simpley called freeze out plugs yes you are fine with the green locktite it is designed for press fit aplications by the way what you are looking for looks just like the plug you inserted into the back of the waterpump i used a meziere wich came with the plug for the timing cover

Napa carries the freeze plus, thats were i got mine. Its not in the computer though, they will have to look it up in the books. I went to a hub store and it was still special order. Pretty sure it was 1 1/4 inch. Make sure you buy brass so it doesnt get nasty on you and corrode out.

How about sealing off the timing cover? Does the kit include a plug for that? I'm going to pick up a CSI over summer.

30thannZ28

no the CSI water pump only came with the freeze plug for the housing to stop coolant from coming out of the weephole. Man, I guess I really am going to have to work to get this thing blocked off..

keep the opinions/suggestions coming!

Well most people leave the water pump gear in place, and don't block it off.. until they the engine apart [timing cover and intake off] then it's best to remove the drive gear, and plug it.. so you can use a regular timing chaion also..
If you leave the drive gear in there, just replace the seal, and let it 'idle' there..
Also, I dont think the Mezeire comes with TWO freeze plugs? Mine had only one? [for the pump housing]

I knocked the seal out of the timing cover and plugged it with a freeze plug. I just took the cover up to Autozone and looked thru what they had till I found one that would work. I had to flare it alittle because it was slightly undersized....then I just put some RTV on it and knocked it in.

I just left the hole in the block open.
