plus this poxy epoxy didn't hold when I checked it this morning, it had enough curing time.

ah screw that, I'm grinding this stuff off and finding someone in Townsville with it. I only have 3 covers not bolted to blocks at the moment and I don't want to dismantle the other 2 blocks just to find out

149C is borderline for this use. The coolant wil usually be less 110C -- on average -- but could get hotter in spots. Especially when you turn off the engine.

Since all 1973-2009 timing covers are identical, why not just get another one?

I didn't think of it but if I did grab one of somebody I'd be spending the same amount of time cleaning and painting it.

I went looking for JB weld epoxy ( said that as a refence but told them what it was) and I got the run around from most places I went to which seems goes to show that:

A. some people have no idea what they're selling.
B. they don't know who I am
Anyway I picked up a two part chemical resistant multi metal epoxy rated to 149degrees celcius, is that bordering on what coolant temps would be?

That's just after I applied it. I used a grinding bur to roughen up the surface and dig out the holes a tiny bit then cleaned it with carby clean.







edit: oh, and
C. it's all a government orchestrated scam to keep me out of my Datsun

Surely someone must have a decent one lying around. I must have half a dozen - if I was closer I'd give one to you.

Get it welded up. My A12 made a pin hole due to corrosion. Luckily to the outside and not to the inside of the engine. They just welded it up and used a di-grinder to get it like it is suppose to be before corrosion.

I made a mount for the water pump belt cover on my mums TP magna with JB weld after the one cast into the alloy valve cover cracked off, even the bolt threads into it nicely after running a tap into it.

Get some two part epoxy like JB Weld and fill in the gaps, then use some emory cloth and smooth and shape as needed. Here is a list of things we fixed with two part epoxy: front tranny mount on VW Baja Bug, cracked fule tank on BSA 650 corrosion, divet on A14 deck between 1 & 2 cylinder, the radiator on my 2001 YZ125 and numerous cases on MX bikes.

Those sharp chunky bits from crap in the cooling system or the pump crapping itself. The pump crap itself on me once but at the time I don't think I looked in the housing when replaced it. I don't want more of those chunks coming loose.

What's wrong with the one that's not corroded?
