Do you hold the accelerator to the floor and then crank the engine? Will this NOT let the engine start but turn it over until oil pressure builds up after an oil change? Thanks for any info

 

That is correct. The engine will NOT start when cranking with the pedal to the mat. Release the pedal and it starts right up as usual...

I just did this the other day after an oil change. I let it turn over for about 7-8 seconds, then started it up.

 

Thanks 01...

 

Just crank it. Engines are designed to just fill and crank. All the other hundreds of thousands of 4.6s and 5.4s have made it all these years without being primed. But doing a manual clear flood will spin it without starting, youre just turning it at about 300rpm until oil pressure builds up instead of 8or900 rpm.

 

It' will help lengthen engine life if you can get that oil circulated before you actually turn over the engine.

 

Isn't it better to build oil pressure at the lowest rpm to help with engine longevity? Sure 100's of thousands of engines are just started after an oil change but since this function is so easy to do on our L's why not do it? It seems that it does more good than harm. Granted we might be talking about engine wear that MOST people would not be concerned about but what the heck if it helps just a little and it's easy to do why not go for it? Just my .02

 

I don't know if it helps or not, but I allways fill the filter up before I put it on.

 

I do the same thing Don. And how can it NOT help?

 

K... I have a silly question for you all. I always thought (W/EFI) it was not good to give it gas when starting up the engine? I've been told it can hurt the EFI system. Like flooding it out from to much gas. Thanks Guys & gals.

 

The ECS will detect that the throttle is at WOT and not fire the injectors at all, so there should be NO fuel going into the engine.

 

Thanks 01Lightning
Good info man. How about a little bit of thottle,can that hurt it any? Sorry for the ??'s

 

Does anyone really think a 380-450 motor will go over 100,000 miles without a total rebuild?

 

I do.

It's like any performance car. It depends on how those miles were accumulated. I don't think most L motors will last that long, but I'll bet a bunch of them will.

 

i think since the engine is turning slower if you try to prime it, it will actually take longer to build all the oil pressure than if it busted off at 8 to 900 rpm. So in my opinion, turning it slow (for a longer time) is cycling the engine the same amount as busting it right off (whick builds the pressure quicker). Im just saying that i never thought it to be negligable to engine wear.

 

Yep. Mine will. I know how I drive & maintain it. I can't speak for anyone else.

How do you think Diesel trucks with a blower, turbo, 2 strokes and 4 strokes, can go 500,000 miles with minor maintenance ?
It is dependant on how they are driven and maintained. End of story.
