Hi Peter, my name is ***** ***** only 1 peephole on the engine. What is this other hole you are referring to? Can you take a picture of it for me?

Expert:  Jason replied 5 months ago.
Ahh Gotcha. If anything it sounds like the thermostat might be stuck open on the cold engine. If you pull the engine cover off, start the engine and let it run for maybe 5 to 10 minutes, does the cylinder head get real warm to the touch? (160F or so)
Customer: replied 5 months ago.
Yes it gets warm. The thermostat is new it also has a miss on a cylinder
