ok well I replaced the sender piece for the oil pressure guage and although its not tight enough still ( leaks a tiny drop) the motor is full of oil and running and after a few minutes the clacking went away.
But, if I press the gas pedal down quick theres a tap tap tap two or three taps, and it stops. If I press the gas pedal gradually it doesnt do it at all. I reproduced it with the quick pressing 4 or 5 times and its consistent, but doesnt seem to be rpm related but more from the quick start of accellerating.
Im hoping its something in the head but I guess it could be a slightly loose rod or wrist pin.
Does anyone have any experience with this issue?
