REFLECTOR: Exhaust pipes heating the oil pan

[Al Gietzen]

Wrapping carbon steel pipes will significantly reduce life; mostly via
stress corrosion.  Perhaps a better solution is a baffle between the exhaust
and the oil pan - if it fits.

He wanted to know why I didn't

wrap my exhaust pipes since they ran under the oil pan (I have a custom

semi-tuned, 4 into one exhaust system).   When I reinstalled the engine

I bought the wrap kit and installed on all exhaust pipes.   Oil temp has

dropped 30 degrees and has yet to break 220 even on long taxis this

summer.   I probably picked up a few horsepower to boot.   It's a simple

fix I wish I would have done seven years ago.
