I gotta question. Me Suby has this rattle kind of sound. Kinda hard to explain. It appears to be comming from the drivers side. It dissapears on acceleration and shows up on decelleration and at idle. It's not lifter tick, that's on the other side where I'm trying to figure out which lifter is being stubborn. I did the ol' breaker bar to the ear trick and found that it's the noisiest in the area of the ditsy.
The cams are 180 apart, and lined up with the marks on the flywheel. I checked the timing and it's bouncing around 10 deg btdc. Vac guage is solid at 16" at 800 RPM.
Here's an MP3 of me Suby running. There'a lifter tick, an exhaust leak and a little breeze amongst the rest of the sound of the engine. Don't know if you can hear it or not.
