Bet no one has seen this... Valve Cover E7 pin hole.


 Share

Recommended Posts

This morning I took off the valve covers and risers to re-seal the gaskets (clean and apply RTV) and throw it all back together. As I was cleaning the forward valve cover, I saw i had a rubbed spot from the turbo oil supply hose (which has a frayed jacket). In that rub spot is a tiny pin hole. Mack wants $210 and will have to order it (Down time :() so my question is can it be JB welded (Epoxy)? They say the temps for the epoxy can get up to 500 degrees? Is that okay or might the motor get hotter? I'm waiting for a phone call from a friend who can weld aluminum (I think that they are) and will go with that first, 2nd epoxy if you guys agree that would work, and third, spend more money on a new one. Pics are on my facebook page.  Andrew Keffer or Keffer Transport

Temps are no way ever near 500 at best 1/3 of that

Water temp only gets 200* or so.   If just a pinhole then I would just JB it.  Clean it up good, scuff it for some good gripping power, don't let any fall inside as you don't want pieces floating around the valve cover.  Make sure to get something to keep that line from rubbing on the JB.

10-4. I thought the temp would only be near 200 degrees but I had someone else trying to tell me that it would be hotter. The covers are still off so I can easily JB weld it without the worry of stuff falling. The hole is about a 1/16" hole. You think wrapping the turbo hose in pipe insulation from Home Depot?

Or use a larger sized rubber hose and clamp it on?  Or a piece of soft braided fuel line?

If you are handy, drill and tap it for a small bolt and lock tite it in?  Then you don't have to worry about it, though the bolt head will likely cut through the turbo line?

There are soldering rods available for aluminium if your after a more permanent fix. Looks easy enough to do from looking at the videos.

I You need to be very careful with the soldering rods. The rods melting point is 700 degrees and is extremely close to the pot metal / Mazak melting point.I use Muugy Weld rod it is made for pot metal repair with a melting point of 350 degrees. Strong, easy to blend in and chromes up nice. Did all the pot metal on my 1941 Chevy and a few pieces on my 1970 Hurst Chrysler 300.  Paul

Because most all consider pot metal repairs voodoo and black magic.  :)

I never knew that existed! I knew about soldering copper plumbing pipes and all, but I watched that video of them repairing the head light bezel, and I'm impressed!

I used a hobby butane pin point torch for better control and bought 1/16 and 1/8th in rods. For my trim parts seemed to work better than the plumbers torch.. Here is the before and after photos of the Flying lady hood ornament before it was plated. I finished it with diffent grit flap wheels and Scotch Brite pads before the plater took over.   Paul

Took almost 50 hours to save it, cheaper than a $1000. for a repro. I'd work on it for an hour or two in the very early mornings when everyone was asleep.
