I'm finishing up my CSI install and have a couple questions:
1.) Do you need to plug the hole in the block from where the WP drive shaft was?

2.) I'm having a heck of a time finding a freeze plug for my timing cover--1 1/4 is too big, 1 1/8 is too small. I think it is a 31mm but Autozone and other places go from 30mm to 32mm. One place recommended JB Welding a 50 cent piece there?? What have you guys done?

Thanks

 

1.) You only need to plug it if you have removed the waterpump driveshaft. I'm going to assume that you have. You can leave it open, if you like big oil leaks!

2.) If you can't find a freeze plug, JB Weld and a quarter will work fine. That's how I did mine! Here's a quick picture:

Hope this helps.

 

I took my cover to a local parts supply house and found the correct size freeze plug.

I just did the same thing as Ken Lowrance in his CSI pump install guide. 2 washers, a bolt, nut, lock washer, & rtv. Worked great, it's been that way for 2 years and no leaks.

Just to be clear, in my first question, I'm talking about the hole in the front of the block leading into the lifter valley--not the hole in the timing cover.

As far as the timing cover, I'll probably go the washer method--just kind of affraid it might lossen up over time....

 

I left the hole in the block open. For the washer 'method' on the cover, I used the lock washer and some thread lock just to be safe.

 

Ahh my apologies...

I too left mine open. I didn't see a problem with it, and sifting through dozens of old posts, I wasn't the only one. No one seems to have a problem with it, so I left it open as well.

 

Do all years have to plug the hole in the timing cover or is this '95 and up specific? I just did what the CSI install sheet said. Will I be ok?

 

You only need to plug it if you remove the water pump driveshaft.

 

The water pump driveshaft is what goes through the timing cover and into the hole in the front of the block, correct? Would it still spin if I left it in there.

And the all important questions, would I lose any HP by leaving it in?

 

I left the shaft in there in case i ever have to put a stock waterpump back in.

 

Take the shaft out. It's what causes 80% of water pump leaks anyway
