I have a question about idleing for long periods of time. I know that your not supposed to let these engines idle for over like 10 minutes at a time, but I had a situation come up that I thought I would ask.
We had a local hazardous waste round-up recently and the line to dump your waste was VERY long, almost like dead stop traffic. So I ended up sitting in line for literally 50 minutes of my Saturday(which I did not enjoy one minute of) to dump my waste. Well, the truck was idleing the whole time(somewhat of what I am about to explain). Since I installed my 3gsk, it idles a little higher than before, like 900 RPM. So during my waiting, I would look at the clock and about every 5-10 minutes of idleing, I would bring the engine speed up to about 1500 or so for about 30 seconds as well as giving it a few good revs once in a while. I would have turned off the engine, but the line was moving at that pace where every time I would have shut down it would have moved a couple of inches and I would be holding up the line and ******* everyone else off.
So, my question, was bringing the engine speed up every once in a while as described enough to keep combustion temps up and prevent heavy blow-by as well as extensive carbon build-up?? A friend of mine who works with me(used to work for Cummins) told me that as long as the engine oil temp is alway above 160*F then I should be fine to idle as long as I want. Well, it was somewhat hot that day and according to my water temp gauge, I thought it was reading a little higher than what it would be on the freeway, so I figured I must be around 160* oil temp. But what do you guys think??
