I don't have any clear cut answers, but here are some off-hand ideas for you to consider. Did you use your timing light to verify that the mech advance was working? Have you compared the Bentley manual with the cooling tin you have to make sure that it is ALL there? Spark plug air seals in place? Did you look at the injector spray patterns to see if they were okay? [This is a long shot, but it seems like you were running lean for some reason.] Were you using good quality exhaust valves (very important) with chrome plated exhaust valve stems, & bronze valve guides? > Everthing BUT the oil cooler.(Damn again) I almost never replace the oil coolers, but I DO clean out the air passages, just to make sure that the air can get thru there and do its job. The exception would be if the engine had destroyed internal parts that could have led to bits and pieces lodged in the cooler. In that case I would be tempted to replace it. > 5 or 6 mile run at 85.Toasted #3 piston.New unauthorised port created. This seems awfully quick. There must have been something dramatically wrong. > Plastic locknut insert laying i valve cover.melted "Plastic locknut insert"? Melted? Something was wrong here. Was the thermostat opening the flaps? Were the flaps frozen in place, or the thermostat not adjusted right? Thermostat dead? -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
