Default Plugging hole in timing cover left by E-wp.

Alright the car is coming back together but before I can put the water pump on I need to know how everyone plugged the hole that's in the timing cover left by removing the waterpump drive. I bought a 50 cent 5/8 freeze plug and it was too small, I don't know it they have an 11/16 there or not. Anyone else run into this?

Ok I measured it and it looked like either a 5/8 or an 11/16, I'll try the 11/16.

Wow, I didn't think JB would hold up with the heat and vibration.

i've been told by multiple people they have had it for years and no problems one guy said he JB'd in a quarter and its been like that for 5 years.... If it looks like it's starting to crack at all i'll pull it and find somewhere to get it welded..

Hmmm I might just gather up some JB weld and a quarter then. Gotta get the car done pretty much tomorrow or Sat so something is better than nothing.

Use a 50cent, it will last twice as long.
Or a silver dollar

You can also use the old seal. Just cut a piece of thin sheet metal and use the seal to hold it in place. Otherwise, the half doller trick works well. I use "The Right Stuff" to hold it in place.
