joka sold his cams.....
they are not "custom" plugs... they are just a certain size... (don't have any on me, trying to track some down for you - but you'll need to wait until after xmas it seems - i've got the guy who made them's home phone number and i'm trying to get in touch with him today to see if he's near the shop at all in the next day or so so i can pick some up...)
they are just a welch plug/freeze plug but the size is going to be important...
cool, can you post up the size when you get it, and also where they go in the head...thanks
is there any way i could get any of those plugs?
they go in the end of the main oil line on the cams.... so that oil pressure builds in the cams to lubricate the journals.
oil is pumped into one side of the cams (the gearbox side) and are stopped at the belt side by the plugs - pressure in the main line rises and oil is pushed out of tiny (and i mean TINY) holes on the journals, which lubricate the cams as they rotate...oils is then returned via one of the oil return lines in the head (you can see them when you get your cam cover off).
without the plugs, the cams wouldn't lubricate properly, you'd probably fill the whole cam cover with oil and make a big mess, as well as break things.
Joka has pm'd me regarding the plugs - it would seem that my previous 2 attempts to ship them to him have failed (i have NO IDEA why.... they are just brass plugs ffs!) - and i'm trying to get them for him. I thought they were for his build, which is slowly progressing, but it would seem the urgency is more about the fact that he's sold his cams...
I'll ship any new plugs i get to him directly as originally agreed and he can onforward them to you.
time frame....no idea...still trying to ring the cam guy (who is probably ignoring me given that its christmas eve.)
