Hi,

About a year ago i rebuild my m20b25 with an ireland engineering 2.9 stroker kit and camshaft and.. full build with a megasquirt ecu at first it was going strong without any problems
but there is now coming a grinding noise from the engine after searching for a while what it could be i finally found the problem
my vibration damper is grinding against my waterpump pullie
the crankshaft is one from a m52b28 i believe, so its a 2.8 with racing pistons so it becomes a 2.9

does anybody know what the problem could be or is there someone who had the same problem and knows what happened or how to fix this?

my e30 is a weekend car so its only done about 2000 miles sinds rebuild

Have you inspected the waterpump? They move about if the bearings are worn

its a new waterpump since 2000miles could it get worn that fast?
I already checked it yesterday with further stripping down and there was a little bit of play on it

genuine pump or aftermarket junk?
