Okay, from now on you don't have to call me "Toby", you can just snicker and call me "That Idiot". The story: I needed to replace my oil pressure sender because the low pressure light was coming on when the oil pressure was at 90-psi. No problem, I go to my VW parts store and get a dual post, 150-psi oil pressure sender, and install it. No problem. Then my car goes in to the shop for the ignition testing. I get her back, everything is fine, and I drive off. Hmmm, oil pressure sure is low (hot day)...damn! it's getting *real* low! Well, it could be the sender so I go back to the store and get a replacement and install it. Oil pressure still too low. This is when I write you volks about my timing since that was one of the things my mechanic did change. I also checked my valve clearances and everything was fine there. Talked to mechanic and he explained what he did -- it made sense and nothing seemed unusual, except for that damn distributor nut (pictures will be posted later so you can see what I'm talking about). I pull the new sender and compare it to my old, failing sender. The only real difference is the info on the sender nut. My old one had "0-5 bar" while my new one had "0-10 bar". Ah Ha! I find my old sender receipt and sure enough, the part numbers are different! I zip on down to the store, show the clerk the problem, he grabs the correct sender (yep, "0-5 bar") then tells me, "The one you have is the correct sender for your 150-psi gauge...this one (points to "0-5 bar") is for the 80-psi gauge." Oh. I see. For several years I've been using the WRONG SENDER!?!? That would explain why I was seeing over 150-psi readings during the winter time!! OH OOOOOH! The clerk was totally cool...I guess he could tell I felt soooo stupid. Now I have the correct sender and the apparent low pressure readings are actually normal for my baby. Which, I now know all too painfully, are too low. So now I really, really, really need to get that secondary oil cooler installed! I still need to attend to fixing the dizzy. I just need a couple more simple parts and I'll be installing the secondary cooler, soon.
