its sucks i only drove the car a week and a half since i got the swap

i go direct to the timing chain im pretty sure it has too much slack. Its too high pitch to be in the bottom end.

RADIR · Dec 29, 2009

its comes from the top for sure but when i pulled the valvecover it look fine

whats the oil pressure

RADIR · Dec 30, 2009

dont have a gauge but when i pulled the valvecover a tund the motor over whituot the plugs oil was comeing good on the rails so i think i got good oil pressure

when its at idle its hardly noticable due to slack in the chain i guess, but once you give a bit of rev and the chain tenses it sounds like something is rubbing against the chain... almost like the tensioner is out of place and hitting it, which doesnt make sense. it sounds like the wheel of fortune wheel. ive never heard a "knock" like that before and its deff not in the bottom end, good luck yo

x2 its to high pitch rubbing sound to rod knock do more inspection in the chain area
