Thanks..Well done!
When I made the video I assumed there was a CCV diapharm similar to gasser valve covers, and the hole was a vent hole which would be necessary for a CCV diaphram. I did notice the new valve cover and another valve cover on a customers car didn't have the hole but I assumed it had been updated.Who the hell drilled that hole in the vacuum reservoir (which in this engine is incorporated into the valve cover)??
thanks.I guess I'll use smaller words next time................
Top notch video Richard. Even though I have a good idea on how the boost is controlled, your video really ties the the problem, component locations and diagnostic methodology all together.
Translation: When your turbo ain't boosting right, your movie really helps a feller get Er done.
I couldn't see any port to let vacuum out of the reservoir into any CCV area. I poured water into the reservoir and it stayed at a consistant level.That reservoir isn't connected with crankcase in any way, right?
In hindsight that was probably a good option. Or a separate vacuum reservoir, like maybe one from a ALH.The cover is the vacuum reservoir? Sheesh, I would've been tempted to try plugging the hole first. A small truss head bolt with a nut and washer and a dab of sealant.
