Default No boost after walnut blast, 30ff. - 07-13-2019, 03:43 PM

So I recently performed a walnut blast along with replacing diverters, pcv, check valve and charge pipe. I now have no boost, I can make about 2 psi max at full throttle. I have rechecked everything to make sure I didn't forget to tighten something or that any of the seals didn't get damaged during reinstall, including the intake manifold seals. All vacuum lines are attached and in good shape. My wastegate adaption was at 150 so I adjusted that down to 90 but did not make a difference. It does sound like I have started to get a little bit of wastegate rattle, as far as I know, these are original turbos with 98k. I will try and get some logs uploaded once I get a chance.

Ftp charge pipe stock diverters. I keep thinking leak but I can't find anything that would cause a major leak.

Also, I did not use the crappie clamps that came with the pipe. I got quality constant torque clamps.

Had the intake off today just to make sure nothing was damaged. I replaced the throttle body oring as well as the intake orings when I did the valve cleaning. All that was still in good shape. One thing I just thought about is the possibility of walnut shells stuck in the pcv and keeping it open. I did have some shells transfer into other intake ports while I was blasting. They had to have gone through the small ports. I had all cylinders taped off except for the one I was working on.

I doubt it. Possible, but I doubt it. Double check the coupler to charge pipe ?

Just to give a little background, I'm not your average diy'er, I wrench for a living, been doing it for almost 20 years. Only thing is, I normally work on trucks, not cars. I have a smoke machine at work that I plan on using just to be sure I don't have any leaks but I'm pretty positive I don't. All ***** are attached, orings all look good, coupler is on properly and tight.

Hard to say then. How well did the tmap go into the charge pipe ? I know you said you are mechanically inclined but sometimes the simple things are over looked or forgotten.

It went in ok, but I had low boost before installed the pipe

I had low boost out of nowhere to find one of my solenoid valves decided to start leaking from which supposed to be the breather port that under the square plastic cap filter next to the vac and line ports.

tapping that solenoid off and looping the vacuum line to 1 solenoid car boosting again 21-22 psi. so I got a used working solenoid from friend and replace it and all now back to normal

I I think I found my problem. One of the nipples on the front wastegate solenoid broke off. I was only getting 5 inches of vacuum to the wastegates. Tee'd them both to the back solenoid and now I have 25 inches vacuum. New solenoids are on there way from fcp.
