Slightly low is different to sunk, sunk is caused by soft block, low is production tolerances. Lots of engines came out the factory low, but it was accepted because its not such a problem with elastomer gasket which was being fitted. Reason they failed was because the elastomer separated rather than low liners. MLS was introduced as a more reliable fix towards end of production and liner heights were more critical
Why didnt they just do it by using a surfacing machine or killing machine... Would of produced better result and taken half the time probably.
