Savage X Engine Help

[Alex-818]

Hey guys, the other day i was trying to run my truck in the cold around 10F, and it was hard to turn on with the roto start, so eventually i got it running and then i noticed to of my engine cap head screw had vanished in the snow, so is it still ok to drive with two cap head screws, and any tips for an easier start in the cold?

10F is too cold for the engine, really. Start the engine immediately after having it in the house, at room temperature - or warm the engine with a hair dryer on low.

Using a piece of sock zip-tied around the head should help keep it warm while running. No idea on the screw, but if it's just holding the plastic trim to the top of the motor, you should be fine. If it's a heat sink to engine block screw it needs to be there.

Your fuel will start to gel at those temps as well. Bad news for the engine.

You need those screws! Very important, don't run in those temps. When it warms up next spring, you engine will have zero compression. You are wearing it out running it cold.

Awww man i was waiting this whole time for snow and i can't run it...well thanks guys for the tips, ill have to wait for temps to go up a bit

Kind of makes sense..... the heat sink and cylinder are contracting due to the cold ambient temperatures, yet the piston inside is still expanding at it's usual rate, being away from the outside temps - yet still subjected to combustion.

That's how I see it, anyway. Plus reduced voltages to the servos and radio.

Overall, not a good scenario.

Dead on Spikes!
