So I replaced a bad con-rod bearing on my performance A14 (which had rotated in it's housing, blocked the oil galley and proceeded to wear itself out). The crank was okay thank god.

I started her up yesterday and apart from being out of tune she ran really well.

So I come back in today and started her and there is the knocking noise again. Off with the sump, oil pump etc.

I remove the spark plugs and crank her free to hear where the knocking is coming from. I am not convinced but it appears to be another con-rod bearing, it has some clearance either side (laterally) so when you give it a wiggle you can hear a knock.

I took that bearing off and it's looking rather worn. Not drastic but enough to raise the eyebrows.

Now I'm going to step back a bit and look at the bigger picture. Is my engine oiling properly?

Does anyone have a quick-check technique?

I checked the oil galleys when I first built the engine (20psi air) and if I remember correctly the crank is oiled first and the camshaft feeds off the crank feed.

I also have great oil pressure.

Does anyone have any advice or suggestions?

Revhead?
