Intercooler Couplings Going Bad?

Been noticing when I clean the engine bay that these couplings on the intercooler piping are consistently more greasy and grimy than the rest of the engine bay.

Is this an indication they could be going bad?

If they aren’t blowing off when you romp it just swap the boots for Motorcraft or RiffRaff boots and you can reuse the clamps just don’t over tighten and make sure the parts are absolutely squeaky clean when you put them back on. Make sure you keep the groove in the tubes and ridge in the boot lined up. Dawn and hot water will clean them up nicely and degrease them. I use hair spray on mine to get them to slip on and stay put under boost.

I have had the full kit for over 25k and love them. Very heavy duty, made in USA and a site sponsor.

+2 on the riff raff kit. Do yourself a favor, learn from me and get them replaced BEFORE they blow off while pulling a camper on labor day 200+ miles from home...

When I replaced my turbo, intercooler, intake, boots and had my intake and pipes off to clean and powdercoat I did the CCV reroute and have not had a nasty oil soaked boot blow off since. Look how pretty and clean everything is after 25k without sucking a bunch of oil vapor in the intake...and never had a turbo bearing failure. The turbo doesn’t need oil from the intake!

Plug the intake hose inlet with a 1” PVC plug

Pull the CCV tube off the intake and twist and pull fitting out of valve cover then cut the center section of hose off fittings and replace with 1” heater hose and clamps so you can turn it the other way towards driver side battery.

Run heater hose down to frame and terminate by transfer case or about halfway down the frame on 2wd. Leave it open ended, never drips at all.

thank you. I was interested in how you laid the hose. It goes up in front of the degas bottle. directly from the elbow downwards is very narrow.

i'd like to run the hose right down from the elbow. i'm gonna look...

Is that oil filter a little tall of am I just seeing things?

When it comes to the boots. You see the lines on then? They are there to help you align then on the pipes.
Clean the inside of the boots well if you have to remove then. If you run into an issue with them not staying
on you can use a bit of hairspray to help get you home. When torquing the clamps be sure to use a torque wrench.
You may find that what you think is tight is in fact very loose. Last thing to keep in mind is the way the clamp
bolts are pointing on the turbo end of things. If you get a blow-off the end of the bolt can dent the hood. The
other thing to watch out for is the lower clamp bolt. Make sure that it's not rubbing on the A/C line or you will
end up with a leak in the A/C and that is not fun.

Two questions...

1.) Any idea what the recommended torque rating is on the clamp bolts
2.) If those two boots are going bad what are the odds that the other two are still fine (basically should I replace them all)?

From the PDF I just uploaded.
Tighten to 12 Nm (9 lb-ft).

You have hot side and cold side with the hot side going bad most times first.
I take it you have the metal driver side pipe.

Received the Riff Raff boots today and noticed that they don't have any indexing markings on them like the OEM boots...is that normal?
