not dizzy, not pre-ignition....(present in all extremes of timing)
what in the world could this be? did i snap a piston ring or something, is it piston slap, engine ticking until it goes KABLOOM or what? sounds like someone put a nut in the fan and its goign clak clak somewhere...under moderate acceleration.. seems vibration related really, as when i first let out on the clutch i hear it for a second. |

this may seem whacked, but check the brake lines at the firewall where the perportioning valve is. I had one line that vibrated against the firewall at certain RPMS and load conditions and made a sound like you are describing.

I removed my wife from the trunk & the strange noise stopped. (IMG:http://www.914world.com/bbs2/html/emoticons/spank.gif) |

maybe you are running too lean from feeding your engine through a fucking straw... (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
is there a "pinging" sound? loose valves? when was your last valve adjust? did your VW mecahinc friend do it? (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) i HIGHLY DOUBT you sontaneously dropped a piston ring or a wrist pin... but with you, who knows? did you do a compression check? do you know HOW to do a compression check? help us out here... we can't heard it over the net through your post... or take it to a real mechanic that KNOWS type 4s... not just type 1s |

check you engine and tranny mounts, and while under there take a small rubber hammer and hit the tins, HE, every thing that can move or viberate. does the sound come from the middle of the car, back ???. i wonder if your throw out bearing is going bad ie, the sound when you let off the clutch
