anybody know what the drain pan plug thread size is on chrysler lm 225 in a 1978 f-32 might be? saw some drain plugs with a on/off valve and hose attached that would make oil changes very easy. seems like it would be better to suction the oil out from the bottom rather than the dipstick.

Don't know size, but I have the drain hose on my Chaparral 454 I/O ... works great - just put the boat on the trailer, run the hose out the dran hole and unscrews the plug!

I don't have this on my Cummins diesels - still sucking ...
