[charlie-2]

i will be removing the cab to do my full egr delete and i was wondering when the cab is off what should i check look at or see while i have the motor exposed? i am doing this mod and a tuner, intercooler pipe, cfm+, and a air intake i am aiming for reliability on this motor because it will be pulling alot since its our 550, what else should i look at or see when the cab is off?

Are you going to do head studs?

[charlie-2]

i was thinking about it but thats more time/money. i thought the stock head studs were actually decent?

Head studs are cheap insurance in my opinion. It's your truck though.

how many miles on the the truck?

from what i hear, 6.4s rarely blow headgaskets but studs are good insurance.... if you're gonna run a really hot tune it might be a good idea

if you're going for studs since your already there i'd put in a high pressure pump gasket and reseal the injectors too. otherwise i wouldn't dig too deep looking for problems. depending on the mileage i'd give the rocker arms a good look too

also if you've never worked on a 6.4 you're in for a real treat

I wouldnt bother with studs unless your gonna be running race tunes which i doubt since its an F550. I highly recommend the Spartan 210 tow tune also..

On a 550, I would pop off the water pump while in there and check for cavitation.

wow! thanks for all the replys and yes this is the first time on a 6.4l always been with 7.3ls haha. but the truck has 69,000 some miles almost 70 i think, but yeah biggest tune is 250 and that comes on the spartin, i will be running the 210 tow!

good advice there! i completely forgot the 450s and 550s are much more prone to cavitating the front covers. it is very easy to pull the water pump. definitely have a look behind there and post a pic too so we can see what it's looking like
