Engine was smoking so badly I had to use spark plug extenders on each cylinder to prevent plugs from fouling. Oil ran down outside of engine from the block/intake manifold interface.
Ran compression test with engine cold. All cylinders have 140 psi compression. Removed head. No scratches on any cylinder walls. Walls clean. No ridge around top of any cylinder.
Had head rebuilt. New valve guides, valves, springs, valves ground.
Reinstalled head. Ran engine. Retorqued head bolts. It smokes as badly as before and oil still runs down side of block.
Looking for ideas on where to look next? Could it be a broken or stuck oil ring? Or ???????????
