Hi all!
I just acquired a new (1984) f4. The engine (845) is making pretty loud noise (tapping or something) under load, especially with 4th gear. Without throttle the noise disappears? Engine temperatures doesn't seem to have huge effect. Engine however pulls pretty smoothly.
Could it have something to do with ignition advance? How about a leak in the exhaust manfold? Worn valves?
Car obviously needs some work but first I should get the car home. There still some hundred kilometers left!
