My old pushrod tube "O" rings were very loose fitting on the head size (red) the block side were tight. Picked up a new set from the Bird and the fit the same, loose at the head end. When I tried to install them the ring would pull out and curl under the lip. Why? I have the old set, should I try the black ones on top too. '70 1.7 now 2056

yep, capn is right. The early 1.7 had 1mm smaller P/R tubes and the bores in the heads are also diferent. The case is the same however..
You can bore the heads for larger tubes and solve the issue, else you'll have to have the correct seals which are NLA as far as I know.. I'd use the old seals and seal them up with my teflon sealant.. |
