Cobra timing cover leaking - 2003-04 Mach 1 Registry Owners Club

Toastr · 06-17-2014, 10:27 PM

It's leaking from the unused bolt hole by the waterpump! I had everything done and when I started the car it started dropping bad.. Anyways took off balancer and waterpump pulley and I found that to be the source of the leak..

Is there any way to plug it up properly without removing the whole cover again??

Should have used more rtv

You'll have to pull the cover and RTV around that hole. That happened to me and made a big mess.

Really want to avoid pulling off the cover if possible.

I was thinking a tap thread and a small bolt with Teflon tape to seal it up?

It'll leak between the cover and block. At least that's where it was coming from on mine.

I simply plugged mines with ultra black RTV and it seal it just fine. And, that was last August.

use the gear oil resistant RTV. It stands up to all oils great.

Took the timing cover off and used a shitload of black rtv this time lol even filled the entire hole

(I didn't leave the rtv like the pic, I smoothed/evened it out and filled the hole)
Hopefully no leaks this time! I installed everything but I'm going to wait till tomorrow to start up the car, open headers and 3am I'm sure id wake up my whole block

Next time, use this stuff:
http://www.amazonsupply.com/permatex.../dp/B001REYVJE

Right Stuff Gasket maker.

You could have used that without pulling the cover.

I should have mentioned, that I merely filled the hole with RTV(oil resistant).
