looking for valve opening angles for a stock cam on a 3.8ltr v6 vp engine. I'm trying to work out if the cam is corectly timed with the crank before pulling the motor apart.
The VPV6 camshaft/valve opening and closing angles.
The inlet valve opens at 31 degrees BTDC (Before Top Dead Centre).
The inlet valve closes at 122 degrees ABDC (After Bottom Dead Centre).
The exhaust valve opens at 73 degrees BBDC (Before Bottom Dead Centre).
The exhaust valve closes at 80 degrees ATDC (After Top Dead Centre).
