I have ran my 89 240 in ITA for 2 seasons with very few problems that I call "serious".
During my winter teardown, I noticed that #1 piston was actually starting to burn. I rebuilt the engine, checked everything that I could think of and started this season off.
At VIR in may I burned #1 completely through. I was having some fuel pressure problems so I changed the pump and had my injectors cleaned and blueprinted to be safe. After installing a spare engine, I went to another race last weekend and now have the same problem. The spark plugs show that the engine in NOT lean and I watched the fuel pressure very carefully - that was not the problem. Does anyone know of a distributor or ecu timing problem that exists here. ANY HELP AND INPUT WOULD BE APPRECIATED.

thanks
