I think after all that work, and finally thinking it was all together, I'd just find a quiet corner to cry in. In fact, now that I think about it, something similar did happen to me when I rebuilt my Mk1 Capri a good few years ago now. It was not a happy day.

Serves me right though! Must have done something wrong maybe the gap on the piston rings wasn't right or something

Gonna have to plastiguage the big ends again to triple check them and find out why they'res a slight nock on start up

And no idea what's causing the backwards grinding

I hope that's something silly but when I get the box off I can then check for any scoring maybe it's catching a bolt

But it's fine going forwards? Odd

Heads off and found some scoring on the calendar walls, I must have done something wrong when the cylinders went in

Found the intakes and exhaust valves full of oil

Also found one of the journals of the crank is scratched

So that's the knocking on start up sound

Either need to rebore and oversized pistons or see if I can hone any scoring out ImageImageImageImage

Bit annoying to say the least, but think positive, you got it in and running, so braver man than me. I've never had luxury of car I can risk major tinkering with, so keep going, it is progressing!

Haha cheers mate

Yeah I know she runs and the wiring has all be done so it gives me a chance to also do the brake calipers while I wait for parts

Downside is having things professionally machined is expensive especially as I'll then need oversized pistons too

I'm gonna try and polish the crank with some wet and dry and I've honed out the cylinders but now there's a bit of play in the piston so need to find out how much I can get away with without causing piston slap

Don’t take the risk order a new crank and journals, also a new set of piston rings

+1

Any unevenness or marking on the crank bearings will quicker become catastrophic.

A piston getting stuck in the bore doesn't bear thinking about...
