Which through bolt holes act as oil galleries?

[elflamo]

Hi all, I tried to search for this, but I guess due to some language barrier I wasn't able to find anything useful.

Thing is: my Victor Reinz gasket set contains 19 blue o-rings for the through bolts. Wayne's book says I need 22(+). But is my observation correct that only one or two of the lower through bolts holes act as oil gallery and the other's won't need the o-ring at all? this is a 4R case.

TIA

HI elflamo
you will need a full set of 24 seals for the engine, as the top of the engine has the oil passage in, I would fit all the seal, and never fitted through bolts with non, if you are short drop me your Add and I will stick some spare in the post for you.

You have 11 cross bolts and 2 studs to seal behind the oil cooler, total 24. Usually Rienz includes 2 extra, at least that has been my count in the past. I would put all seals on all cross bolts, no need to create extra oil leaks.
The bottom row has oil galley for the intermediate shaft web.

Well, I guess that I'll be ordering some extra seals (did just that at my local shop, thanks Mike) and using seals on all through bolts then. But it still makes we wonder (just curious) if they are really needed on all bolts on the lower side, except for the intermediate shaft web indeed.
