GOT a strong flashlight with a good wide beam?
When dark out, open hood, start truck and then shine flashlight beam across top of engine and look for any misting etc.
Then go to high idle and repeat.
Don't look at light but look thru light beam ---do same down along side of engine
Any misting/smoking etc should show up in flashlight beam
Is it time for your medication or mine?
