Big problem after Updated Fuel Spring Regulator

[LegitLogan]

I recently installed the blue spring upgrade, and right after the install i took the truck on a test drive. After about 10 min of driving down the road, an Extremely loud POP came from the engine and the rpms went from 2300 to 500. Me and my friends thought we hit something in the road at first but there was nothing. Then we drove home and you could definately feel the low power...now the turbo shows no boost and i can see no leaks in the piping leading to it. So i think the turbo is shot.

I will go look at it more thoroughly later today. any help would be appreciated

Check the silicone boots on the tubes to the intercooler and the turbo. One popped off.
If you don't find any problems with those, and you have the plastic tube on the drivers side, check that tube over from end to end for a crack or hole.

By the way, if those boots are a greyish/brown color due to grime, it is time to replace the boots anyway. That grime you see is actually oil that is present in the intake air stream that has been pushed through the silicone boots and dirt has stuck to that oil. The oil comes from the crankcase vent installed just previous to the turbo. One thing to keep in mind is that silicone (which the boots are made of) breaks down in the presence of oil.

If the boots look good, use a solvent such as acetone to clean the area of the tube you will cover with the boot, and clean the interior of the boot with the acetone as well. You want to remove the oily film, so do not scrub the acetone hard into the boot. Just a wipe and let it dry. Connect the boot to the tube, reinstall the clamp and tighten to spec, DO NOT overtighten. You will screw the tube and it will no longer hold the boot on. If it pops off again, reclean the same as before and raid the medicine cabinet. Steal your girlfriends or wifes hairspray (unless YOU have some left over from the 80's ) and spray the hairspray on the tube and inside the boot. Let it dry a minute or two and put it together.

Thanks a bunch for the info, i know the boots are all really dirty and they probably do need to be replaced. any idea how much they cost from ford?

I don't recall what I dropped for those, It has been awhile. Guessing right in the $100 neighborhood.

NYC hit the nail on the head. If you have a plastic intercooler tube, and you removed it to do the spring, I'd bet it cracked-they are prone to doing so.

Thanks guys found out I blew the intercooler hose under the intake. It looked fine, I cleaned it and clamped it back on. But now the Turbo seems quiter lol. And has about 3psi more than before the line blew
