| POR-15?
POR-15 is a Paint Over Rust convertor product. You were using it as a cleaning agent.
Huh?

Over the weekend, I pulled the manifold (huge job and not for the faint of heart) and the flaps were so coated with soot that they creeked when they were opened and closed. At a certain position close to being closed, they actually got stuck and had to be pried open. Anyway, I cleaned all with POR-15 and old toothbrush and the car is quiet and very steady. Hope I do not have to replace the manifold in the future. Sorry to be the bearer of bad news as I really like these cars!
So, what would cause such a build up of soot on one car? Bad fuel, short trips without proper warm up, running on a bad glow plug? | |
