Cat Cams 288/280 with Oil Bridge mod

[bmwfnatic]

Im at this point now where I've gotten a set of 280s with followers and the oil bridge. I cant find information on detailed specifics of how to drill the rocker arm shafts. I've tried to get a hold of CatCams via phone on their website, IG DM, but nothing so far. If anyone has some detailed information/documents please share.

EDIT: Are the holes for the rocker arms and the oil bridge just on one side, or do they go straight through? I think judging from the exh cam shaft its just one side but I have no idea.

Not knowing this kinda withheld me from buying them from the forum member, I went another route instead.
I recall there being one picture posted on Facebook somewhere by the Catcams owner's personal account, which sorta outlined how to do it, but not in very much detail, I hope they get back to you.
I believe in that same Facebook post they also stated they can do the drilling for you.
