Alright, I'm fed up with trying to find a 31mm freeze plug for the waterpump driveshaft seal area of the timing cover and I went to use stainless steel washers to plug it, but I got carried away with the dremel and accidentally grinded too much off the inside of the cover. I need to know if ANY other vehicle out there shares the same bolt pattern and same size crank and cam holes on the timing cover. I have the OBD I conversion and therefore don't need the CPS anymore and also have the CSI pump, so I don't need that hole anymore. Perhaps someone on this board will know if maybe and older chevy or such has a timing cover I could order to put on my LT1. I'm sick of the stupid issue! It's keeping me from fininshing the mods in my sig!! -frustrated....

 

Why not just put an expanding rubber plug in it and be done with it? (one of those things that has rubber sandwiched by flat washers and a bolt through the middle)

 

You can use 95-97 LT1 cover from f-body.

You can use 95-96 imp SS cover too if you are going junkyarding.

Arent the LT1 covers really cheap though, 30 bucks or something new.

 

Dude instead of getting a 31mm plug what I did was found a plug that fit in the SMALL hole itself.. I don't remember the size But dude just pull the cover or measure it with a dial caliper and go to your local autoparts store, tell them to bust out their clevite catalog, then someone in there is a section that lists all the freeze plug sizes clevite makes.. Just match one that fits your size and BOOM good to go.

The one that I found fit PERFECTLY inside that tiny round hole, but it wasn't like a press fit so what i did was just put copper sealant ALL OVER the FRONT & BACK of the seal, gooped that $hit on everywhere Then just let it cure.. NO MORE waterpump seal to deal with ever & no more leaks Been like that for about a year and a 1/2 now

 

Epoxy works well, as does liquid steel or JB weld.

 

Uhhh that's a big NO NO... Epoxy and JB weld DO NOT mix well with oils... Put that stuff in and say BYE BYE bearings

 

I meant to patch up his timing cover, not to use inside the motor.

 

WERD but if he usues it to patch up the inside of the timing cover then that is in the engine Either way, copper silicone works just fine, that $hit will harden plenty

 

Ahh, just skip it.
