Will JB Weld live in this application? - 07/17/09 06:25 AM
I'm gonna try it & I believe it will be fine, but a buddy of mine insists it's gonna fail.. What do you think...

What I've done is epoxy these into my valve covers..

So I can mount baffles...

So the breather & PCV have proper baffles

Sure will make a neat noise if the JB weld does fail and that baffles falls onto the rocker arms 
Don't you think tig welding some little 'pegs' onto the valve cover would have been a more permanent fix?

On the one side I agree & I considered it, but the material is cast & fairly thin.. I wouldn't try welding it myself but my buddy who is insisting it will fail is an absolute artist with the TIG.. But I've known of racers using JB Weld in much more stressed areas with no problem.. And I felt by usiing the "T"nuts I have plenty of surface area & I roughed up the back of the "T"nuts pretty good... The cast aluminum I left raw other then cleaning throughly...

I know it will work. I have some of those Cal Custom valve covers and they didn't come with baffles. I just have some chincy sheet metal screws that barely grab into very shallow casted holes held in by JB Weld.
Been that way since about 1994. With the stout suspension and cruising at 3800 RPM for 40 hours across country they have never vibrated loose.
Now about every other nut and bolt on the car has managed to loosen itself in the meantime. But those dumb baffles have stayed in place.
My front spring eye nuts loosen all the way up about in a years time.

I would have tig welded in alumminum standoffs and used mounting bolts with saftey wire. Those little screws could do alot of damage if one comes loose. You could still safety wire and at least if something came loose it would all stay together. 
Don't all the holes in the baffle kinda of defeat the purpose.

It'd be tough to clean the valve cover thoughly if you could not get the baffle out exspecially if there was some kind of failure.
FWIW I have drilled through the valve covers to mount baffles, doesn't look as nice but at a glace I could tell all my bolts were in place and it didn't leak.

My father had a boat with an old 40hp Evinrude outboard. He stripped the threads on one of the cylinders and decided to give JB weld a try. I tried telling him to use a heli-coil instead but once the old man decided something that was it. I thought for sure that he'd have a 50mm round flying as soon as the motor started. But to my surprise it held for many hours of use. Moral of the story - I'd be real comfortable with your use.

The screw I'm actually gonna use are stainless steel allens with a nylon insert so they don't loosen unless you want them to...
I actually feel all the little holes are gonna help improve drainage.. They started live as nailer plates for reinforcing wood construction, I've had them laying around for a few years & they were close to the right size..

Another vote for JB Weld working just fine.
Planning to do some framing under there someday?
To answer your next question, I think PT would work better in that environment than plain Doug Fir...

Doug Fir would be better to support the rocker shaft though...
I wonder if Simpson Strong-Tie would have motorsport support for you?

So I should probably just scrap the one I carved out of Oak...E...
As far as Support goes, I'm more likely to get support from Homer Simpson...

I hear you, I love to use what I got laying around too.

I don't have holes in mine.
Filing it with oil is a pain.

That is exactly what I remember about trying to fill with the early stock covers & why I thought the little holes would help... The good news is we all understand the need for baffles, something the companies making most aftermarket covers seemed to forget about...

Even with baffles mine still pukes oil. Maybe that has something to do with that 16 year old re-ring job the standard bore.

Nope. Comes from too much negative camber.

Or maybe from the lack of building materials in it.
Maybe some CDX sheeting as a baffle..

Nope, got that covered. My seat brackets my dad made to fit the Toyota bucket seats are made of oak on a radial arm saw. They are contoured to the floor. After a while I thought it sat too low. Solution... some scrap 1x1's and longer bolts on the drivers side. Keep the passenger side low for tall people.
