Update on my rig

[IHPowerstroke7.3]

There are only two per cylinder

Lmao... You funny guy.

There are only 2 rockers per cylinder.. 1 rocker actuates both intake valves, the other both exhaust valves. Its the same setup as the 6.0, the 6.7 however has 4 rocker arms per cylinder, 4 pushrods but only 2 lifters per cylinder.

Where are the rocker arms breaking? Are the balls breaking off the ends or are the clips failing?

That was sarcasm.... They use bridges, just like almost all of the other engines out there.

the cryo was more for reducing wear imo than strength. In any case keep me updated Eric and let me know if you need anything.

Thanks man, I will but no info yet......

Any word yet?

Should know mon. Cab is off, they are closed for the rest of the week

Keep us updated.

I know it won't be much stronger and it may have been done or at least said before but what about cryo treating a set of stock rocker?

gotta remember that cryo treating doesnt add strenght. it takes all the grains in the metal and makes them equal so that there is less deformation in each piece and making it less likely to fail do to a flaw in the granular composition...

Cryo way mainly done to help parts not wear out as fast as they normally would

yes sir! that goes along with what i said too...

Well #7 is melted, #5 is burnt, one bent valve on 7. Sending heads out to go through and fix the valve. Sending injectors out to see if one hung.

Damn, that's too bad. Sorry to hear that.

 

[Bustedknuckles]

Wow that would make me sick. I would put a cummins in it honestly.

GTFO of here with that sh1t.





That sucks buddy, did an injector hang open or something?



On edit - ***king lo***kingL on putting a cummins in it.... the most notorious motor for melting pistons lol totally help you with your melted piston issue.

Or you can make the same or close power he is making now daily driven for over 30,000 miles and never have the head off......

Lol you just described my stock motor.

If the piston had cracked, I'd be less inclined to argue with you, but pistons don't just up and melt because they want to. Almost always an outside effect that melts a piston. Something like injectors, valve issues, nozzle problem, etc. Which is why I find it funny that you suggested a cummins; the commonrails have more injector and piston issues than fords by a huge ratio.

Thats true.... the piston issue is way worse on 6.4's than cummins imo, the amount of 6.4s that have made it over 200,000 miles on the stock engine is VERY low compared to cummins....

 

[Mike@MPD]

Get the hell out of here with that Cummins nonsense

I agree, but the piston flaws seem to attribute to cracking; which is a casting issue from Mahle. Like I said, if this one had cracked, I'd be less inclined to argue...

similar to the number of Dodge/Cummins trucks that have made it over 200,000 on the stock transmission, dash board, driver seat, ball joints, ECM, TIPM, HVAC blend door assembly, AC compressor, etc, etc, etc
