A couple weeks ago, the car started running rough all of a sudden. Found that a wire was off No 1 plug, AND the plug was loose. Last had them out for a valve adjust begining of July, right before a 360 mile round trip to the sierras, with no issue.
Anyhow, pulled the plug, and put it back in, trying to feel for cross threading evidence, but it felt fine. Car ran great again. Now, today, on a 80 mile round trip, it loosened up not once, but twice. What could be causing this? |

QUOTE(r_towle @ Jul 24 2012, 03:15 PM)  It may be time for a plug fix kit Only about 8k on rebuilt heads. Holes were welded up an retapped. That being said, I have heard the inserts are not that bad. Seem to recall hearing that 356 racers went with inserts because of all the pulling of plugs and re-installing. Who sells the kits? |
