Turbo issue after bpd install

[stlouisgto]

I just installed the bpd oil cooler and egr cooler on my 05. I've never done anything like this ever on a vehicle. Most I've ever done before was a valve cover gasket an a GMC Sonoma I4. Took me about 20 hours to do it until I went to add coolant and had a leak. I had to undo the whole job................just to find out that I forgot to put the o ring on the egr cooler At least the second time around it only took me 10 hours to take apart and put back together. Truck pretty much started up right away and only sputtered a second then idled fine. But i was hearing a whooshing sound from the turbo. was starting to think that the y pipe wasn't on properly then all the sudden the whoosh went away for a few seconds then the truck sounded with the normal exhaust tone for a few seconds then back to whoosh. It seamed to cycle like this a few times. Any thoughts? There wasn't any boost pressure on the turbo. When I stepped on peddle for a bit my monitor started to show pressure building but nothing really. The truck does have an aftermarket exhaust and air intake. I haven't taken it out for test drive yet but will tomorrow at least to gas station, she's a wee bit low. At the moment truck turns on and off no problem

Sounds like the turbo vanes were cycling. You probably still have a leak.

Check the pigtail that goes into the front of the turbo. The wires might be exposed and touching one another- this happened to me after my BPD install.

I still need to find a spare pigtail and splice it in.

those damn exhaust clamps look great on paper( i am sure thats what the ford engineers said), but a bolt up turbo exhaust flange would be sooo much easier.

The v-band clamp is a good secure clamping system and quite typical in turbo setups. But you have to make sure everything is lined up and not depend on the clamp to draw things together. You won't make any boost just revving the motor in park or nuetral, it needs a load on it to spool the turbo. Check all your connections plus the hose to the map sensor from the passenger side of the intake. Things will sound different due to the egr delete.

I didn't do the delete. I live in California so I went with the cooler for emission laws
