I can't really pinpoint it excactly... I put my ear on the valvecovers; no real noise there...it's coming from deep inside...my guess is from somewhere around the crank...yes I did torque both the rod and main capbolts, both being new from arp...and several times (loosening and retorquing up to 5 times)...(they were too tight at first!!)
from your reaction I think I'm going to drop the pan again! Besides the caps and bolts there, I should probably also check the crankscraper, maybe that's the problem.(was too narrow at first, maybe it still is off by a small amount)
any ideas what I'm looking for? a loose cap or bolt?

Don: It's running quite hot, quite fast, but with 11 to 1 CR that should be expected, right? (hence the electric waterpump and new radiator) I don't have real figures on the oilpressure, other than that it flows...

PS:
ow, and there's no noise at all, when i crank the engine on the starter, it's only when it runs!
