I have just finished a complete overhaul of the fuel injected 1.8 liter engine from my 1974 914. I reused the pistons, honed the cylinders, and installed all new rings, bearings, gaskets, and seals. All fits and clearances are within factory limits. The engine is reinstalled and I have set the dwell, timing, and valve clearances. It is running very well except for one thing.
I now have clatter (or a slight mechanical rattle) that ONLY occurs between 2000 and 3000 R.P.M. during deceleration. If I apply any amount of throttle the noise goes away. I have combed the entire engine compartment and undercarriage for sources. Other than the torsion bars for the engine lid and rear trunk lid, which now have rubber hose insulators installed, I can not find anything else moving or hitting other parts.
If anyone has a suggestion I would be very grateful.
