Engine strip on cards

Yep already in that process . 

Valves good , barrels good , rings good , small ends good , big ends feel good . 

The hunt continues !!

Did you check the valve clearances before you stripped it ?

Leaking head gasket I reckon.. Look for carbon deposit marks on mating surfaces..

Yep clearances were the first thing after compression check . Cheers

Cannot find any fault with the gasket - but will be changing . ( wiesco metal type - faces were machined flat about 3000miles ago , and still check out flat ) 

have now however noticed - worn rear cam guide - which would I think explain the noise at temperature . And the rings on the cylinder in question look to have slid round to be in line . I set them up at opposites on the original build . 

Going to use the opportunity to replace both cam guides and give the valves and Pistons etc a bit of a shine . 

fingers crossed the decoke and ring spin will perhaps deal with the comp . 

Anyone else had ring gaps line up to do this ?
