PSA check your turbo inlet hose:

No comment on metal hose but a word of advice on install/reinstall of the rubber/plastic hose. Be sure to push/pull/twist the airbox end all the way up until it touches the MAF sensor before tightening the clamp lest you crush the airbox lid outlet. Been there done that as has another member who will remain nameless.

Well,

I guess I am the lucky one here. I pulled the inlet hose off this time checking for other things and it still looks great!

There was oil coating the bottom of the hose at the interface of the hose and turbo inlet. The plastic looks good and I put the hose back on.

Any thoughts about a metal hose like I posted last year?

I don't think I would do a metal hose on such a short run. It's built with bellows to allow it to flex because the engine rocks quite a bit from side to side. Plus it would still need to have silicone couplers at both ends to seal to the turbo and airbox, so you'd be talking about maybe 3" of metal tube in the middle, not to mention provision for the CCV inlet.

I'd buy a Samco Sport one tomorrow if they had one.

CCV inlet???

'pa-toohey'

Mine won't have that!

Oh wait, for all those EPA monitors.... I am j/k

I have yet to call Samco Sport back about this. I caught the R&D folks at lunch on Monday and have not had a chance to call back yet.

Do the coolant hoses look right? It seems awfully wrong the way they are routed

Excuse if this hasn't been answered before, but are these inlet hoses located beneath or behind the air-filter box?
I'm still completely new to this and while I spotted where the turbo actually was(below the CCV hockey-puck) I'm sort of at a loss to spot exactly where these vital hoses are.
I've done a few long trips, but I'm holding off anything of major distance until I get most of all the prescribed preventatives out of the way.

It's the hose that connects the airfilter housing top/lid to the turbo... so "behind" would be a good description

Sweet.
I'll check this out as soon as there's more light around.
Thanks in advance.

Mine not broken and have been using a Provent for a few years.

bentstrider83 - when you are in there checking it take a look at the impeller at the front of the turbo. There should be no evidence of scraping of the impeller fins on the housing and there should be no more than a slight amount of for/aft play and no more than a bare hint of side to side play. When reinstalling the airbox to turbo hose be sure the airbox end is pulled/pushed up to where it touches the MAF sensor before tightening the clamp and don't godzilla the clamp as either can result in a crushed airbox hose outlet (I know).

If you have not already done so read thru Sam's NOOB guide.

I'll definitely be checking for that too.
I've read the n00b guide and have been following it thoroughly.
That MAP sensor clean seems to have made an absolute difference in things.
MPG prior to that was dicey, but after cleaning, I made a trip from Clovis to Lubbock and back.
A little over a 1/4 tank was used for the entire trip!!

Figure around 30-32 mpg compared to what was 24ish prior.

+1 on all that. PapaIndigo is giving you the straight skinny.

Turbo cooldown is, I suspect, a very important bit of keeping this engine running right and lack of soot load and frequent oil changes is another.

Sam just gave me a heads up on this thread (as a result of the oil I mentioned in another thread coming from my turbo), so I'll definitely be checking this asap --especially since there was such an abundance of oil on/around/below the turbo when I checked at purchase (which I thought was from the turbo oil drain line, but everyone is suggesting might be this or the CCV hoses instead).

Any leads on "better than stock" replacements yet?

I will also be sure to check the turbo fan, as papaindigo suggests, if and when I am replacing this hose.

Found mine cracked today. Have been checking it each oil change, But noticed a small amount of oil leaking from the turbo intake where it was cracked. Lasted 104k. Check them often boys.

Dealer cost $59.20 but charged me $46.15 it will be here in a the AM. The best price i could find was $40.83 + shipping from Factory OEM parts.

My MAP sensor clean changed things drastically as well. However, I have actually seen a drop in my MPG... but that's probably because it's SO MUCH more fun to step on the pedal now. :shock:

I am loving this little Jeep! :lol:

Just a quick update, I've replaced the air box to turbo hose, at almost 122k, the old hose looked very good, maybe previous owner replaced it before (got the crd at 78k).

But I'm glad I did it, less things to worry about! It seems the provent is doing its job, there was no oil in the cac hose and all the oily deposit on the replaced hose (outside) was old and dry.

104K that is how long the fresh air hose lasted on the Sport as well, only because I broke it while removing it for an engine mount replacement. It may have lasted even longer undisturbed? :POPCORN:

I saw 2 months ago a kid on the forums asking about high idle and 3 inch idle and all that stuff that the big diesel guys do. He said his had a metal Intake tube on his. I cant remember where i read this or what his username was. However, im thinking of doing a metal tube when i do my exhaust on mine. We will see, can anyone thing of a reason not to run a mandrel bent pipe? other then not taking the rattle of the engine all to well?

I see no issues with making a Metal intake other than you will still need a flexible hose to connect the metal intake to the turbo. It must have flex! As the engine moves within its engine mounts and the air box dose not.

I do however feel replacing with the OEM every 100+k is a much better idea.
