[Vwdiesel] Electric oil press gauge & wet floors

[Bryan Belman]

Travis, I have lots of experience with the electronic oil pressure gauges.  For years I thought I had some issue with TOO Much oil pressure in my  Vanagon.  So, I took the long way around instead of checking the easy basics first.  My problem sounds like what you are seeing.

No 1.6 or 1.9 IDI diesel can make more then 70lbs psi oil pressure.  That is what many people said to me when I said I was seeing 130PSI at startup and 45-50 running down the road when hot.  No I see why.

I have a 0-150PSI VDO 2-1/4" guage.  It turns out the dual (idiot light wire and oil psi sender wire) VDO sending unit in the head that I had been using all these years was 0-5 bar when, of course I was SURE is was 0-10bar.  I checked this LAST.....So I changed the oil pump ($$ and waste of a night) and pickup tube thinking the pressure releif check ball was stuck or something.  This of course made no difference in how my gauge was working because it had nothing to do with it.
Then I removed the VDO sending unit and cleaned it off.  Sure enough it was stamped "0-5 bar", that was my issue.  It was doubling the oil pressure reading to the 0-150psi guage.  I got a 0-10 bar dual VDO sender and all is fine now.

5 bar is 5x14.7=73.5  most of the VDO gauges are 0-80psi
10 bar is 10x14.7=147, the next VDO gauge is 0-150psi

check your sending unit against the gauge you are using.

Few questions for the group. Since my brothers mishap with his oil line breaking on his truck and actually being the cause of it running out of oil we are getting electronic oil pressure gauges. Question is what happens to an electric gauge the stops at 100PSI when the engine is cold can produce 130 PSI on all 3 of our engines. Will it ruin the sensor. I have heard of the mechanical gauges blowing up under pressure. I am limited to the Autometer Cobalt blue in my car as I have all the other matching gauges. 

Next question. My 04 Golf has the rear right side passenger floor wet when it rains. Is there more then the two sun roof drains. I know of the two that at the front doors and they aren't plugged. Is there any that could be filling the rear right pass with water? 

Next question is on my 81 rabbit truck. The right passenger floor under the seat is wet really bad. At the corner where the side and back meet I can see a trail of muck left from the water and at the back panel where the bottom panel above the carpet meets the one just under the rear window it is leaking on the right side as well and it starting to rust under the pain in the body panels. The trucks joints have cracks in what ever they used in almost the whole truck. The body is all there and there is almost no rust, just the cracking in the factory joint sealants. What do I do to seal it up. I doubt it is the rear window seal because a couple years ago I put a split window in and put enough sealant in where I don't think I can ever get it out thinking it would solve my wet floor problems. Then I moved to WY where it doesn't rain much but it has the last several weeks so I am again reminded of the floors. 

Both wet floors are when parked overnight in the rain. 

Last question. I asked a bit ago if anyone knew where to get the rubber plugs for a 78 camper can VW for the brakes. Nothing on ebay and I don't even know what to look for on it. 

Thanks
