The Big Brown Truck showed up today








It'll be back

 

Getting serious, are you now, Steve?

Mostly reliability upgrades, but as long as it's gonna be studded I figure there's no harm in looking for a little more.

 

Got a mod thread going steve? What are your goals?

 

No thread, not really doing anything groundbreaking. Just trying to keep the heads from flying off while I'm going down the track, and addressing the known weaknesses in the HPO system on the 05+ 6.0. Probably going to get a little faster but not too much.

 

Just 'cause I don't keep up with the Six-Oh's, but Bro Bob does, what ARE the HPO known weaknesses? He's got that crew-cab '06 (I think) with one.

I gave him a coolant filter, and he's got that installed.

What else should he be addressing until an injector gives up, or the EGR cooler or oil cooler clogs?

There's an updated 1 piece fitting for where the branch tubes connect to the HPOP. There have been a lot of failures of the original snap-to-connect (STC) fitting. there's also an updated standpipe.

Here's some pics: This is the original STC fitting shown:



This pic is of an '03, which uses a different pump and oil rails, but the flow path is the same and it shows the standpipe:

 

Sweet! A go fast turbo! Good thing the brown truck guy did not toss it over your fence!

Funny you guys bring that up. I just checked my truck into Grody tonight for what I think is going to be that exact issue. I should know tomorrow if that's what it needs.

Congrats on the new parts, Steve. Is that the newer Garrett Powermax turbo?

 

It's the GT3788VA. Been around for a while, other than the compressor wheel being a little larger it's pretty much the same as the stock turbo.

Hard hot start/long crank on yours?

 

Best to keep this in context.

Sorry it's Friday.

 

The inherent danger of posting incomplete sentences has been noted

 

Thanks for noticing!

The crank is longer again. I think I mentioned that this has been coming and going for a year or so. Doesn't matter if the engine is hot or cold. I watch the ICP while cranking, and it takes longer than it should for the pressure to build, and then once it comes up to 500 the engine bursts to life. So I think air is entering the system when the engine is off, and the pump has to reprime.

Could be the IPR, but I think it will be the STC fitting. If you have an '05 or an early '06 with that fitting it is probably just a matter of time before it fails.

Any guesses on what the dealer will charge me?

 

If it's the STC fitting I'd guess no less than 15 hundred. Just a swag though. 60 dollar part, lots of diagnosis to pinpoint and lots of labor to get at it. Hopefully it's the IPR.
