5.0 short block replacement
#21
FYI - The F150 has a factory oil cooler that keeps the oil around the correct temp, so it doesn't "thin out" under use, even in hot weather.

Mileage on original block
OP, how many miles did you have on the original block, and is your new short block the updated 5.0 block? It's my understanding that Ford made changes to the 5.0 block in 2014 to fix the cylinder distortion issues. Hope that the replacement short and long blocks are now the updated blocks. Thanks and good luck with the new engine.

Oil coolers help, but the oil still heats up. It still gets hotter when towing and it still gets hotter during warm weather. I promise.

When I got my 2013 f150 supercrew 4x4 5.0 I change the oil at 1000 miles 2000 miles then at 4000 miles. Then at every 3000 miles. Have 13000 miles. Quiet as a mouse. Strong as a Bull. I know I can go longer but I'm fine with every 3000 miles. I will change my transmission oil at 45000 not at 100000 miles. Fluids are the life blood of all vehicles.

Rnlcomp - Take my word for it or not, your truck engine is not the same 5.0 from a few years ago. I am Ford factory trained on engine repair and it IS due to the closer tolerances between the bearing surfaces of the crank, as well as all 4 cams in the engine etc...
All of the below specs are straight out of the 2013 Ford shop manual.
Camshaft journal to bearing clearance 0.001-0.002 in 0.001 - 0.003*
Crankshaft journal to bearing clearance .0009-0.0018 in 0.0001 - 0.0015*
Connecting rod to crankshaft journal clearance 0.0011-0.0027 in 0.0006 - 0.0032*

Go ahead and shorten the life span of your engine if you wish but don't say no one warned you.

Updated block?
Some have asked if it is different. I could not tell with a naked eye but here is my new OEM short block that replaced my knocking 2012. They took the cab off nice and neat, and put it back together the same way, nice neat and clean.

RNLcomp I respect your dedication and knowledge and value your advice on this forum. That said I firmly believe that CAFE is dictating thinner oils for maximum gains in mpg for each fleet. I've also noted the 2017 6.2L in the SuperDuty is now specified 5w30 after being 5w20 for several years....and that in part is why there is speculation about using thicker oils in our F150s. Based on the following post I believe that opinion is backed up:

gDMJoe, thank you for that; I'm in agreement that since the Mustang's 5.0 can go to 5w50, and mechanically the oiling systems are the same, that there's no harm in using a 30 grade (or maybe even heavier) in our F150s.
I'm currently in the early stages of testing thick vs thin oils in my 5.0 and will be posting the results once I'm finished....it will be a couple years but I'll try to remember to post here. I'll be running 0w20, 5w20, 5w30 and 0w40 oils. They'll all be Amsoil, to take away any differences between oil manufacturers and will be run similar distances.

I know I am late for the party but in regards to the brake in on a new short block it's very simple. Drive it normally with no heavy towing or drag racing for the first 1000 miles or so. A good precaution would be to change the oil maybe at the half way interval just for good measure. Other then that just use what ever oil you prefer and drive it like you normally would. Nothing else is needed.
also 5W-20 is perfectly fine for the 5.0. 0W-20, and 0W-40 along with any other full synthetic is a waste of money unless you live in insanely harsh environments. North Alaska or Arizona.

I am taking this new block on a trip that will put about another 800 miles on it. I now have about 500 on the new block and running perfect. I was planning on changing my oil out afterwards or so too, and put the same MC 5w20 semi-syn back in. I was thinking after a good breaking in of a couple of oil change intervals of going to a full synthetic like the castrol extended performance. I will still chagne my oil every4-5000 miles as i do a lot of short trip start and go which is harder on it than just hwy miles. Keeping this truck till it drops!
