it's a bit like buying a Crate motor. would you still pull it down & check everything? this engine came to me as a fresh build wrapped in cling wrap plastic. it was meerly a case of pull the pan, check the bearings were new & the parts were what it was advertised as. unfortunately for us now we've found there was dirt inside the galleries as all the bearings show contamination. but when all the holes are plugged i kinda expected the engine to have been built to some degree of expertise. live & learn i guess, trust nobody, no matter how highly they're regarded. looks like i'm the best engine builder i know & thats' scarey!
