Engine Lube Question - fresh rebuild

I think the knock pins on the MKII are actually around the front outer studs. I thought there were oil outlets behind them too, but looking back at pictures I don't see them:huh: I'll check the manual to make sure but I don't think the 1000's have the orings there. I'd just like to check the head for oil when the engine is cranking but I'm not sure where to check.
I wanna fire this baby up but I don't want to burn up the cams.:blink:
I don't see any oil paths on the outside either. There would be a hole in the gasket where the o-ring cut out is milled. The oil must be going up the center or someplace else, because it has to get up there somehow.
The knock pins on mine are also around the front studs just like yours.

1) The top of the crankcase does not seem to show any oil passage in the area at the base of the cylinder, but the cylinder base gasket has a hole for one over on the right side only.
2) The head gaskets show holes for oil passages on both left and right.

i thought the oil went up the outside studs...dont you have brass washers on the outside for this reason?

I do have the copper washers but I'm not sure if the studs are the only place that feeds the head or maybe they are returns?? Either way, the studs don't go up as high as the cams, so there has to be a passage from the studs up to the cams. That was the original question waaaay back when - does the oil come into the cylinder head anywhere other than the cam journals?
That redline lube looks great. I'm sure it's very similar to what web cam supplies. I put that sticky red stuff all over! I just don't want things to burn up after that wears off. It's only supposed to help until the oil gets pumped up there.

since you have the valve cover off, and you have lube on the cams, add some oil on top and fire it up, you should see some oil working its way from the bottom.
You might shoot a PM to Jay, bet he knows the right answer

comes up through outside studs and returns through cam chain area,unless youve got really loose valve guides .77KZ650 wrote:

It didn't really answer my original question though which is "does oil come into the head anywhere other than the cam journals?".
I'd like to try starting it with no cam cover but I've never known anyone to do that. Won't it throw oil everywhere? Anyone ever done it?

Wonder if it could be started with half moon cam end plugs removed ???
Must be some way find if the oil passage is clear. Could you put a clear tube over the passage and suck oil up with something like a turkey baster or pour oil down ????? or blow compressed air down???
I'm just rambling. Dont pay to much attention.
Good luck
