Hi all,
I've taken apart the B20E I eventually want to put into my 122. As told in another post, it's a 8-bolt crankshaft, which I heard is stronger (really?). After a thourough inspection, it appears that one main bearing and the corresponding rod bearing (is that how you call the machined part of the crank on which the rod gets hooked?) are slightly marked. I can feel with my nail that a tiny spur has been made into the metal of the shaft: same feeling as if one single sand grain had gone halfway around each bearing. There is no stain or anything (no heating, I presume). A few persons have told me: "put everything back in, it'll work just fine". I'd like to hear your experiences with installing a non-perfect crank (with its original bearings, of course). Any short term trouble (i.e. before 100'000 miles?)
ALternatively, I have acces to another shaft which is supposed to be perfect (need to check) but it's a 6-bolt. Will the rods of the 8-bolt fit this crankshaft? Then I guess I should keep the bearings that came with the 6-bolts: will they fit as well?
THanks for your ideas and feedbacks! Séb
