Thanks fpr the replies. Dave, I am at +80 as well (Silk pistons)unfortunately. I have now removed the engine. One big end has worn through on both bushes so is shot. The other has blued the rollers and the outer bush is turning in the rod. Both little ends are gone. Both inner bushes ,which I believe should be very tight, slipped straight of the crank pins. 3 years and 6000 miles ago it was all perfect. At least the mains seem tight!
Thank you Roger. I am planning to go to Mallory though sadly not Scott-mounted. Yes please bring an aerosol of laquer. See you there.
