Just been messing about with my engine, ready to make a start on rebuilding it. I rebuilt my new block last year, but it's cack, cos I did a few things wrong. So had the original engine stripped, found out it was 60 thou overbored, and decided to use all the (balanced) rotating bits out of current engine in the new one. Follow so far? Good.
I am the first to admit that some things confuse me, so I read up, ask advice, and read again.
I have just dropped new piston rings into bores, and the ring gap is massive. The block is a 1703 Consul, which is 3.25" plus the 60 thou. That makes 3.310. All bores are close enough.
The piston ring gap at the point of TDC is about 200 thou. I was under the impression that it should be about 3 thou per inch of bore, the manual says between 9 and 14 thou total.
My initial thoughts were the box says 60 thou over, but the rings had been changed in the box, but looking on ebay there's a set, with the same markings. RA8146+60, and the mounting card says PSL21. Hepolite rings.
Can anybody shed some light on this, or am I totally missing the bleeding obvious.
