Your 30 lbs oil press at an idle after engine warms up to operating temp is an indication your rod bearings donot have excessive wear. the noise your hearing in all likelyhood is just as truckernix explains. also the 292 may be a bit more prone to acquire these rackets due to the piston speeds if the engine was ever turned a little hihger than is normal. I have seen these engines run many miles with these noises....Ronnie
