97’ HDJ81 with JDM 1HDFT
I recently installed a PDI intercooler to the rig with a buddy of mine. After looking at a bunch of forums and asking PDI/chat GPT how to resolve the vacuum piping, the glow plug light is finally off but I am still having this high pitch noise/whining/whistle coming from the bay. It doesn’t happen at idle anymore but screams once under load at around 1500-2K rpm range. I haven’t done a boost leak check and she seems to have a lot more power once repiping but the whistle/whine is still intense. We initially thought it was a vacuum issue but since most of that has been plugged or routed I’m wondering if it’s a boost leak or something worse. If anyone has installed the PDI intercooler to a 95 or newer 80 id love to hear your take or see if you have had similar experiences?
