With these new shells you are adding a unknown variable and if it goes bust it will be very difficult to prove that it was because of the shells. But if they are of better quality while being cheaper than OEM its certainly a tough choice to make. |
Hi Julian. Fair enough point regarding oem std shells. This motor had already spun a shell some 20or 30 k ago , new shells oem were fitted by a bmw tec. Good lad to,””no names””. as he did it at his home ,, it ran reasonably well up to 100k ,, though they was some of the old shell left on the crank.as crank was never taken out and any kind of polish,,,Later shells didn’t look to bad to be honest, so don’t think pickup on crank was from new shells, original shells were down to copper colour,, I’ve now polished up crank myself old style bootlace job 1000 grade wet dry and metal polish,, all still measured up ok bmw spec, looks prity good. From what I’ve vied So called professionaly polishing isn’t exactly high tech machining “Unless bmw factory done imo”. To be fair can’t really fault oem shells. But they can be suspect and fail to
Hence request for feedback king shells or other ,
