batmmannn is on a distinguished road
Default Tapping

Not sure yet, it could be a timing issue or it could be a broken valve spring. Not sure. I have it to some degree on both my cars. One fella told me he put a washer in between the distributor tightening adjustment bolt and the head to make the distributer pull slightly away from his head and this took it away from his. Others have mentioned it could be arcing plug wires or spark knock from incorrect timing. I have been working on the Red Supra. my Black 87 is the one with the loud noise. Once I finish getting the Red one road worthy I will try to find time to work on my black one. Doing the exhaust and tires now.
