the trick is to drill the easiest hole first... then stick some masking tape round the drill to mark it so you know when you are about to break through, then you can go nice and careful at the end, and use a big drill, I think did mine 3.5mm.

Also it helps if your used to drilling holes with sub 1mm carbide drills, the little bastards are like glass!!

Anybody got any pictures from fitting the BMW jets? Like to see the drilling.

In the 13's at last!.. Just

Thank you.

At the end of the M8x1 tapped hole, is it just a small 2/3mm hole towards oil ways?

Also how deep have you gone with m8 (7.5mm to tap)?

Do you guys use a copper washer under these jets?

Yes straight into the oil way.

Jim. Mine don't have washers beneath.

I have copper washers under mine.

Cheers, I'll give it a go!

Just waiting for my end mill bit.

if you need more pics have a look at my build I think pages 2 and 3

I've drilled the two easy ones, need some longer drill bits to do the others. As they're right in the corners being a 1330, so none of my bits are long enough to reach.

I did snap a drill bit, ham fisted!

I'll have a look at your pictures.

Found your pictures, interesting you did yours next to the dizzy drive.

Looks good.

I am not going to use the drive so it should not be an issue.
