Recently swapped the head gasket on my 87 turbo. Car started up on the first try but seems to be misfiring. Checked and rechecked the cam gears and cant seem to get it close to being timed. When a timing light is hooked up the mark on the crank pulley is pretty far to the left of the numbers on the block, you can get them somewhat closer together by moving the cam sensor but they are still at least an inch or so away from the first mark. Any suggestions on setting the cams/crank correctly without tearing everything apart? The misfiring seems to lessen the closer it is moved to the timing marks so we are assuming that is the problem. The second issue is that the stock water temp gauge no longer works, checked the wiring on the plug (2 pin on housing in front of cam sensor, right?) and it seems good but nothing is goin on. Would really like to get the car up and running without having to spend more on a water temp gauge.
