How do muckers 
With all this down time I've been enjoying sorting my mega list of things to do around the house, absolutely loving it, skint as a church mouse , but loving it.
Any roadup it came to pass that the Black Pearl was needing an engine rebuild again
Last year after less than a 1000 miles the old lump literally spat it's oil out big time. Oil blow by was horrendous.
I did a comp test and true enough the wet test was double the dry. Suspected piston ring failure.
Sooo, here I am again with the engine completely stripped down.
On strip down everything seemed ok till I looked carefully at the bores. They looked quite marked like from the rings but the biggest thing was the ring gaps that should be 25thou, are now 4.26mm
Here's a view or two of the bores.
All the pistons seem ok but here's a pic for your delectaton :thumbs
It's been suggested the hone I had done was rather course and had no cross hatching, combined with suspect quality rings :nenau
I'm off to an engine specialist tomorrow to check the bore sizes for tolerance etc.
Wish me luck :lol
