yea as you look at the front of the case, just to the right hand side of the pully wheel, big allen bolt plug that plugs the oil gallery....

Sorry to hijack this thread but anyone know the purpose of this access hole ? Often wondered..

as far as i know its just where the oil gallery is machined (drilled from the front of the case during production, the ones on early cases ar plugged with a solid bung and later seem to be a threaded allen bolt type, i think it would be quite a good place for my oil temp sender as oil is always flowing past that point, also considered drilling and tapping the bung on the top of the case (the one behind the distributer on the left) anyone have any opinions on the best place to mount?? i recon the bet place would be the plug on the left half of the case in the middle of the bottom oil gallery as i think this would measure the temp of the oil as it flows to the crank...??
i was just worryed that the sender might foul the cylinder heads (ive yet to see)! :hangloose

I think it is the earlier engines that have the threaded bung, which was eventually replaced by a plug. I also think it is larger than M12 with a fine thread. I am fairly sure that it access' an open area near the cam shaft gear and would only receive 'splash' oil, so not a good place to put the sensor.

Ummm...thought about in my type 3 filler blank plate as well!?

Don't think it really matters where it is as long as watch it and notice any change fomr normal...I guess before the coller, after the bearings would be best option but don't know if it is possible without looking at a flow diagram.

after the bearings... where does the oil go after the bearings?? does it just trickle down back into the sump?? or is there a return gallery ?? anyone got a flow diagram of how the oil sys works??
