It's time again for a traditional tune-up -- as we know, this is vital to keeping the engine running at its most efficient.
- Air Filter
- Spark Plugs
- Plug Wires
- Seafoam Treatment (or similar solvent)
- Oil / Filter Change
I could have waited until warmer weather, but the valve cover gasket/seals are oozing and stinking up the place, so I have some time and here we are
Problem: Auto parts store gave me the wrong valve cover sealing set -- of course I had everything apart before I realized this.
Solution: I'm fairly new to wrenching, but common sense tells me that I should have checked the part at the store first! (if you can). Now I'm waiting around for my Wife and the other car to return and head out again to get the right part.
The SeaFoam (AutoRx or similar) was added directly to the oil galleys with the valve cover off, and into nooks and crannies that appear to get gunked-up readily. After everything is sealed up, a quick drive around the block should cycle the solvent and oil through the bottom end and back through the valvetrain. Then the traditional oil/filter change will occur.
Question: An analysis of the spark plugs show them to be in good shape. I assume it's normal to have a slight layer of a white, powdery coating on the electrode? No damage or oil buildup is noted.
With this info, the ultimate question is what "Temperature Range" do I choose when purchasing plugs?
The engine is running hotter than stock, with a 190-deg F thermostat, grille block, and warm-air intake. I haven't had any detonation/pinging problems.
Any ideas?
