Right. Basically we pulled the engine apart and found that the cylinder bores were fucked and needed that it needed new shells etc...

Took it to a local engineering place and got them to rebore it to 0.5+ oversize and check the crank and polish/grind it if need be and supply shells etc (would they have noticed a bent crank while doing this?).

Picked it up, lubed everything that was needed to be lubed, in oil and put it back together (once with the main caps the wrong way round so the crank didn't even turn LOL). And this is the result so far.

Crank turned free as owt before we attched conrods pistons etc...And it even turns free until the point i have described.

Stu mate, the engine was running without much problem before the rebuild (i.e no knocks and bangs) just wasnt producing any real power. So i just thought that a bent crank wouldn't have been a possability or oval conrod caps. Thats my inexperience showing through now innit!

As for the conrods caps being mixed up...would this cause the crank to not turn at all? Like when the main caps were mixed up? Or just stop it turning where i am describing?

Are there any marking on the caps so i can wip the sump off and make sure they are on the right way?

Will still do what Sean said and see if it makes a difference.

Sick a cunt here
