start the Truck sitting for long time ???

Become a company driver and just let the shop deal with it.

 

Get on Youtube and watch 10 or 20 of the old 'revival' videos where they start up old trucks, tractors and construction equipment that's been sitting for 30 years or more. There are a ton on Youtube. They fire em up and go down the road. It's amazing.

I'd fire the mechanic and fire up the truck.

 

Gravity pulls everything down. Including oil on the cylinder walls. Metal to metal don't go good.

That's why it's recommended to pour oil in cylinders if going to sit awhile.

I don't know about diesel motors. But I see a lot of low mileage motorcycles with serious Blowby. Weak compression.

And that's probably what your mechanic is thinking. Dry cylinder walls.

I've seen broken rings and scratched walls.

Again. I don't know about diesel motors given their longevity compared to cars and motorcycles.

It's taught in automotive class that the worst wear and tear occurs from startup and the few seconds it takes to get oil pumping again. When sat for awhile. It's also taught to fill oil filter before installation to minimize the time for pressure to build back up.

Guess I just got fired.

 

What do you think of the start/stop technology in new cars? How that will affect the engine in the long run?

 

Personally I think you're doing much, MUCH more damage when you cold start an engine when its below freezing vs from sitting for a year.

 

Yeah. I'm not too hip on the 2000 rpm cold start imports seem to be doing that I've seen so far.

I don't know. The earlier motors are breaking pistons. But don't know if it's because of that. Mine has a module that disables the start stop. I installedit myself. I see some are coming with buttons now to turn it off. Chevrolet wise anyways.

 

Well one reason why my beater pickup has a preoiler is because of this issue. I learned a long time ago that bring up the oil pressure before the engine is started, even if it drops, is best for the engine.

my roving mechanic I use has a system for trucks sitting a while in some fleets, he made an pressurized oiler that he somehow hooks up to the engine and let’s a half gallon of oil at 60 psi into the galleries to spray oil in the areas that needs to be sprays, like the cylinders. He claims it helps the engine start with minimal wear.

 

First of all if @AModelCat tells you anything believe him 100%. He's a full-time mechanic that knows exactly what he's saying.

You're fine. You have nothing to worry about.

What happens is when you shut your engine down oil drains back down to the crankcase but there still is a film over your internal parts.

Starting it after it has been setting a year-and-a-half is no problem.

The problem is if the engine was taken apart and everything was cleaned, then if you do not prime it you will have metal on metal which causes rapid wear.

I have a friend that is a Cummins mechanic and I asked him about this specifically because I have 2 backhoes that sometimes sit for a year at a time and he said the same thing, no problem.

So relax everything will be fine.
