I start my truck up every morning before work, let it idle for ten minutes. Is this good for it? Do I need a high idle solenoid? I notice when i first take off there is a decent puff of blue smoke. Thanks!
You do more harm than good letting it idle when the engine is cold.
Low cylinder temps = unburnt fuel which washes the lubricating oil off the cylinder walls and rings.
Eventually fuel gets past the rings and dilutes your oil.
Not a good situation, do as Joe says, start it and drive.
yup, fire it up, give it a second to get oil pressure and work its way through everything, then sputter on down the road.
The only time mine sits and idels is at a high idle 1200rpm+. In the winter time i will fire it up, idle it around 1000rpm for a minute, then up to 1500 and a few more minutes and she is starting to warm up!
