Running In
Posted: 18 Jun 2008 15:51
I don't want to make anyone here feel old but I wasn't really around when morini engines were brand spanking new. I've run-in my fair share of rebuilt morini engines but the 501 i have just put in the dart has only 500 miles on it since new...
So, what's the general consensus with running in from brand new as opposed to a rebuilt oldie? the morini book says 1500km up to 6000rpm and then another 1500 up to 6800, slowly building the revs after then. That's an awful lot of miles!
I've rebuilt the engine with a stator side roller main bearing and it's a nikasil bore jobbie so that should speed things up a bit. So far I've done 700km on cheap oil and have just done the first service and put decent oil in.
I'm quite proud of the way this engine went back together and would rather keep it in one lump for a few more years! But equally I know that in a months time I will be at cadwell, so I'd like to at least give it a fighting chance with a half decent run-in...
