Reply to "CMC Speedster running hot follow up"

John; you do have the last tin on the photos that Wolfgang posted; it's in place. I believe you are doing the right thing by getting OEM tins; they fit better and in some instances have parts (like the deflectors in the cylinder head tins or the internal vanes in the fan housing) that the repops don't have. The type of oil you run can also be a factor. A friend of mine here in the Ft. Lauderdale/Miami area was using Shell Rotella 40W; then switched to another oil brand and viscosity and under the same conditions the car's oil temperature dipstick lit up the oil pressure light. He switched back and it was fine. Oil weight is also another balancing act; I've heard the two versions that using heavier weight oil makes the car run cooler and the opposite. Also; make sure the valves are adjusted correctly; especially exhausts. The factory spec for stock aluminum pushrods is .006"; when using chromoly pushrods it's zero loose lash. Some people prefer their cars to be a little noisier but cooler running with looser valves  rather than tighter.
