Turbo Wastegates

Turbocharger wastegate and actuator assembly:
The turbocharger wastegate and actuator assembly is at least partially responsible for eighty percent of the manifold pressure related problems with today’s turbocharged aircraft engines, yet very little preventative maintenance literature can be found on the subject of wastegates. Various troubleshooting guides generally ignore the wastegate when dealing with manifold pressure abnormalities. Quite often, mechanics in the field make adjustments to the fuel injection and turbo controller components to compensate for problems that are actually partially or totally those of the wastegate.

Mouse Milk Penetrating Oil - Every 50 Hours:
RAM strongly recommends that the wastegate butterfly shaft and the wastegate actuator shaft be thoroughly lubricated with Mouse Milk penetrating oil every fifty hours, or at any time the manifold pressure seems sluggish. The Mouse Milk can be applied using a common oil squirt-can. Mouse Milk penetrating oil is available at most aviation supply houses.
