Mein Auto: what ever starts
Okay slow weekend 'cause my wife is home and I have adult supervision. Waiting on the headers and going to attack to oil temp gauge issue. Since the car will only be on the track from here on oil real gauges would be nice. I looked at different methods of getting a mechanical gauge hookup up and liked the Truner set up that goes in the pan. Part of the fun of any project is seeing what you can come up with yourself. Had the gauge for @$40. Picked up the block off plate from the dealer for $15.


Here is the issue. You need to get this probe to the oil so we are drilling through the cover. I thought tapping it but you have no way to secure the probe. Normally it would be in some sort of block and the flare seals like a AN fitting.


So digging through my pile of stare crap I found an adapter that allows you to use the probe on a larger threaded opening. This is what I need.


So drill the cover just large enough to allow the threads on the blue piece to fit through the hole. Secure it from the back with the adapter using it like a lock nut and you get this.




One issue left. The thickness of the cover is slightly large enough to prevent you from getting a full seal on the sensor. Very close but off by just a touch. So you have to bring the bottom of the adapter(red) to the threads(blue). You sand down the back side of the cover or the top side of the adapter and you get a tight seal. When finally installed you use a little rtv on the flanges and good to go. Turner piece is $80 plus shipping. Save about $60 and have the satisfaction of doing something myself......and probably displaces less oil the the original sensor. Testing the gauge prior to installation will give you an idea of how accurate your gauge is. You know what temp water boils at so have at it. Gauge checked out fine.


As for the diff, no issues on the cover, one guy did not know it had been gone. So I saw a kit on ebay and then thought why can't I do this. The threads on your diff cover are M22X1.5. I thought where am I going to find that crap? No worries, it is the exact same pitch as most oil coolers so you have tones of choices for what to run for lines. I will run 6 or 8 an.


Now that that issue is settled I will try to swap the dif next weekend. I can always cap the fittings if I don't have the rest of the plumbing. It should be fun to see what the dif feels like with the current engine. Scheduling the bearings for three weeks from today. S54 power for Christmas!
