RooDog, the rubber hose should be the ventline to the oiltank. Because you mention it: Just wondering how he turned that elbow-fitting ? Space is a bit tight there. The other one between the rear tappetblock and cylinder should be the wiring from the coil to the distributor Well I sorta agree with your take on the (possible) MIG weld job. With TIG you can dump the filler wire into the pool forcing possible existing air cavities outta the cast. Damn Thanks for being so attentive!! Ray
