Engine Noise

[Aches n Pains]

Ian,

If any of my engines sounded that good I'd be thrilled.

Aches

Lol, it sounds smooth a few feet away. I guess I over-thought this whole thing. The phone I used has dual microphones, so it picks up noise my ears actually don't hear.

That slapping sound is definitely your cam chain slapping around a bit. I just installed a new cam chain tensioner gasket and after properly setting the chain tensioner my slapping sounds went away. From what I understand, its a good idea to reset that cam chain tensioner if it hasn't been done for a long time since that chain will stretch over the years (refer to the last part of "head removal and assembly" in the manual for how to do this, it normally takes taking the valve cover off). As far as the gurgling sound is concerned, have to re-tightened your exhaust flanges as of late? I know with mine I have to torque them down occasionally because vibrations/heating and cooling tend to have them work their way out (since I don't know of any lock-tite that can withstand those temperature without burning).

For the newbies...don't remove your valve cover to reset the cam chain tensioner! To clarify, YES, to check stretch you have to remove the cover, but not for setting cam chain tension.

Depends on what you're calling "Reset". I used to remove the cam chain adjuster, push the plunger in all the way and lock it, re-install the tensioner, unlock it and let it slap the chain, then tighten. It resulted in bent valves once when all the chain slack went to the bottom of the motor.

If removing the adjuster, it is a good idea to remove the valve cover and pull the chain slack up to the top of the motor by advancing the exhaust cam as you let off tension. When you re-install the tensioner, it will pull the slack and cam back into place. But if just putting the timing on "C", loosening the adjuster set screw, then re-tightening.. You are correct. No need to remove valve cover for that.
