RE: Check the head exhaust surface
By Courtney Bolze - 10/23/2002 11:08:25 PM; IP 207.68.54.40
The can says Alvin's Lab Metal and it can be found at any place that sells welding gasses, it's not cheap, I think $14 a pint paint can. Check the shelf life on the bottom of the can, it does not last long after it has been opened (5 months) it turns hard in the can. The stuff is great, can drill, machine it etc when it cures. It has metal in it. It was reccomended to me by a metallurgist who I get to do any of my aluminum welding. I plugged the exhaust ports with rags, built up the exhaust surfaces with lab metal and worked a flat file between 2 ports for hours until they were flat. Drove the car to work today and still no leaks. (just love those tri-y's in the tunnel!) I had the original 390 GT exhaust manifold surfaced years ago (1988) and put them on w/o gaskets, but did not have the head exhaust surfaced, it leaked from day 1 on #4. When I took it down in 2000, all of them had been leaking to some extent. If you can't find lab metal I can shoot down to the garage and get the info off the can, CNB.
This thread, so far...
