Hello, Following the recent discussions about turbo after-run, dino/synth oil, and such, I was reminded about the image I had of an exhaust manifold. The picture was taken during some engine-oil tests. The entire (4-cyl, non-VW) ex. manifold is glowing red, as is about 8" of the pipe. If anyone would like to see it, I'm happy to send it on. The jpg is 182k. The gif is 636k. cu James
