Timing side crankcase oil drain mod

Forums

Just thought I'd ask if anyone has lowered the oil drain in the timing side crankcase to the lower left of the oil pump?

This is supposed to reduce the oil temp whilst still maintaining adequate splash for lube elsewhere.

I'm just about to put my cases back together so thought I'd see what the general opinion is!

Thanks a lot

I think anything that comes from or is promoted by Mr Comstock has merit. Knowing how much hot oil otherwise gets trapped in the timing side it has to be worth doing. On the other hand if it's not causing a problem then......I'd probably do it but all back together after a winter cam replacement. With care it can supposedly be done with the engine built up!!

Thanks, looks like I'll give it a go- Mr Comstock seems to know what he's talking about!

Hi Roger- if you trawl the web ('Commando crankcase drain hols') you'll come across this.....

There is a book of mods from the NOC Shop (INOC Tech Digest I think)- there are planty of mods you can make!
