Cold Engine Start Up Protection

[idiabuse]

who said they wont run all worn out? many IDI engines run until they run away on their own oil!
I have a 7.3 engine I tore down years ago, previous owner said it's a running engine, I tore it down anyway and the bore is STD above the ring wear to the deck surface, but the cylinder wear taper is horrendous! I measured it and it wont clean up at .060, block is junked! but remember it was a running engine!

I have one of those pre lube systems sitting in my closet. It connects to the stock drain bolt or by using an adapter that goes between the oil cooler and oil filter.

It is basically an electric pump that pulls the oil from the pan and pushes it through the motor up to around 60 psi. It has a controller that allows it to be set to run for 20 seconds all the way up to 2 minutes before starting the motor and after shutting it down. It serves two purposes, oiling the motor before startup and ensuring that the turbo has fresh oil to cool off after shutdown.

Why is it in your closet and not on your truck ???

I was planning on putting it on when I put on a turbo, but I keep selling off every turbo kit that I get.

I'm running Amsoil 15w-40 diesel and marine . THat stuff has a-44 f pour point. I have a serious feeling I'd need to plug in to get it to fire below that temp in which case still no flow restriction ( block heater would heat the oil up some). Mine fires up on one cycle of the plugs without being plugged in at -20 and colder

Lighter oils like the 0 and 5 wt usually don't fare well in mid range or heavy diesels, due to the nature of the beast they just burn off more easily.

I've been using and selling amsoil for over 25 years and I could easily try to sell folks on the more expensive lighter oils, but can't do it honestly. They just don't work as well overall in this type engine, they generally wind up with unacceptably high consumption rates . THe 15w-40 is ideally suited for the application and it's one of their cheaper oils as well.
In this country , there aren't many comparable options, in Europe where diesels grow on trees, there are more heavy diesel synthetics.
Even those high tech nice and tight low emission euro diesels mostly spec a 10w-40 synthetic and not a 5 or 0 wt

I have had great results using the thinner stuff in my IDI I had to sweat a lil but in the end it was worth the time. I went 5 years no change then finally took a sample at 40,000 miles, this is what came back

That worked great, but unfortunately it came to an end when I for no good reason took my truck up to 120 mph for a 8 mile stretch, that scored one rear cylinder and piston. 2.5 years later upon reassembly I find that the rear cylinder that failed had a clogged piston oiler, clogged solid, just one, all the rest clear and clean. I bet since I owned the truck it was clogged solid.
I had to tear it down and rebuild it from scratch.
So gone is all the N/A 7.3 stuff I had.
All new turbo spec short block, balanced, .020 cylinders, New castings ported cylinder heads. Lots of upgrades to the engine...
I will be buying a new batch of 5W30 diesel again and I should pull 25 mpg again like I did before.
I will use the 5W30 oil as break in oil and it will not get changed out either.

In the past I used the 15W40 AME and it worked good but I dumped it, that hurt! but I noticed an improvement with the 5W30 HDD
So the clock is ticking and soon I will have my truck on the road again, hopefully for more than a decade!
