Zero Turbo Boost
We were cruising about 5 miles from QZ when my dash buzzer went off. The
coach had a lack of acceleration. No grinding noises, oil leaks etc. All gauges OK, except zero turbo boost. I took the air filter off and peered down the intake, the turbine can be seen spinning and the filter is clean. I noticed there is a blue small diameter hose that appears to come off the rear area of the turbo...is this the line that goes to the turbo boost gauge? I'm thinking that is malfunctioning, or one of the large diameter air pipes may have "slipped" from it's mate. We have twin beds, how do I gain access to the front of the engine, from the bedroom? Suggestions? Steve Harrie '86 PT38 8v92 [Non-text portions of this message have been removed] |

Steve,
Here is what I know about our Bird. Our's is the queen island bed. To gain access to the front of the engine, the mattress has to be lifted, boards removed, and then a double plate about 18" square, has to be removed. Lots of screws and sealant. Heavy too, but all comes out as one unit when the screws and sealant are out of the way. The hex bolts through the plate are to hold the double plates together. Do not remove them. Use a hack saw blade to cut through the sealant. Use sealant when reassembling. I'm not familiar with the twin bed arrangement. But I checked a '86 PT38 on BirdConnection. Looks like that center drawer between the beds comes out. The access hole/plate might be under the drawer on top of the base that the center drawer sits on. That is the position of the access hole/plate in our Bird. Good luck.

Hi Steve,
Not sure what dash buzzer you refer to, but it could be the heat sensor in the engine compartment. Ensure neither the super-hot, nor the after-cooled hot air is funneled near anything combustible. We have lost/burned-up coaches to this issue when the only first clue was reduced boost and loss of "zip." Typically, cracks in the intake side of the cast manifold was the culprit, but anything that dumps exhaust into the engine area could be devastating.

I believe that if you lost all your boost, you would leave a trail of
black smoke a long way, not just a lack of acceleration. I would bet you lost your gauge connection or a gasket on the turbo. R.E.
