I have a 2005 DPSM drive behind a LS L92. I had the engine built last year and installed a new flywheel and coupler. Recently I’ve been trying to identify a rattle type noise coming from the rear belhousing area.
I’m at a loss and would greatly appreciate some other minds here…
I ruled out deteriorated exhaust flappers, it has none because they discontinued them before 2005, to confirm I ran a bore scope though the exhaust from the engine bay and out through the bellows and it’s clean and clear, gimbal bearing is perfect new (recent), u-joints perfect (recent), engine alignment perfect and I could spin the alignment bar with two fingers, outdrive does not seem to make noise when I poke around with a stethoscope. It seems like it’s coming from the bell housing/coupler area and the stethoscope confirms that. In gear or out of gear, on the muffs or the water the sound is still there. It seems to fade out around 1700 rpm’s and higher. Could just be the engine sound drowning the rattle noise out. The coupler and studs are new from the engine build last year. I do not want to pull the motor again. =( I’m going to try and attach a video clip or two. Thanks for any help it’s much appreciated.
