"I have a Crusader 502 with about 400 hrs. on it. Oil pressure is 60psi. at cruise and 55 at idle. Oil consumption is about a quart in 20 hrs. No blow by. The engine is just mechanically noisy, almost diesel sounding. Remind me of my old 392 Palmers. Anyway, I've been told by a mechanic that the "noise" is caused by Crusader's use of forged pistons instead of cast and I shouldn't be concerned. He said it will never be as quiet as an auto engine. Sound right?"
