the spit test
thank you for looking at an old thread.
Question #1) When doing the spit test is it on the glow plug or on the top of the head/fin?
Question #2(bonus) When using a raytek temp gun it shows real time and max temp. I sweep it over the plug and over the head bolts. I usually see the real time temps at 230 or so but then the max sometimes grabs a 290 degree. Would you say the engine is running at 290 then?
Please spare the anti-temp gun speech. almost to that point but not quite. Thanks!
