VR6 Engine tech / Exhaust leak on cold start

« on: November 24, 2016, 03:22:02 pm »

I noticed a horrible noise when I started my van on a recent trip.  Something like a loud rumble.  The noise always happens when the SAI pump comes on during a cold start although I believe I have heard it when running the van cold.  Pump runs ok and isn't the source.  Combi seems to be ok.

I tracked down the source and it appears to be coming from near the exhaust manifold.  I can feel the rush of air but haven' taken apart all the bits to get a good look at it and it' tucked back behind the engine.  It seems to be coming from the hole in the photo or another one near it.   It's not coming from the exhaust header.  If i cover it with my finger, the noise goes away and the engine idles normally.

At first I thought it was a bolt that fell out but this picture was taken a few years ago when I had the valve cover off.   Is there a slug that might have fallen out here?  Another orifice that may be the source of the leak?

Interior! / No backlight on cluster

« on: February 24, 2016, 10:11:21 am »

Started happening a month or so ago.  I *think* i coincided with a fast-blink on left turn indicator but can't be sure.  That problem is intermittent and comes up with temperature or moisture changes (can't tell which one yet). 

All gauges appear to work correctly.  Dials light up.  I took the cluster out to replace what I thought was a burned out bulb but found that all the back lighting is LED.  Dimmer has no effect -- no intermittent flickering or signs of life.  This leads me to suspect a voltage regulator in the cluster.  Anyone have a similar issue?

VR6 Engine tech / 24V Tensinoner Failure

I didn't record the sound this makes when the engine is running but was able to replicate it manually.  If you hear this tak-tak-tak noise, your tensioner is failing.  Change it!

Here is the difference between the failed tensioner and a new one (dry).
