Oil temp gauge. Help, inputs, ideas
I'm going to install a oil temp gauge this week and I started doing some reseach on best locations to install it and this is what I came up with.
1- oil drain plug adaptor from autometer: Easy to do, heard the temperature probe doesn't sit all the way inside the pan, leaks a little, and some times it reads lower temperature from oil just sitting there and not flowing threw. 2: Drilling and taping oil plug: Cheapest to do but same problems as #1 3: Sandwich plate on oil filter: 40-50 $$$, gauge reads higher due to heat soak from block. 4: Top of oil pump: I saw this on trackdog racing, looks like a good spot but it said 99 & up. Not sure if my 90 would have this threaded spot aswell, and what thread size it is. Any other ideas? Spots? Inputs? |

Amazon.com: Auto Meter 2267 Oil Pressure Metric Adapter: Automotive Just came in yesterday, will install this weekend. |
Why not just drill/tap the OEM drain plug like your #2... seems cheaper and faster than #1 and the stock plug doesn't leak.

I know I could do that but I don't want to get false readings. That's why I was going someone had any better ideas

Agreed that the drain plug isn't the best option, it just sounded like you'd decided to go with the Autometer plug which was why I asked.
Are you running an oil cooler? |
Drain plug worked fine for me. I switched to the sandwich plate when I got an oil cooler, didn't seem to change the reaction time and temperature reading much (besides it being a little bit cooler thanks to the oil cooler).
Never leaked, and now it has a plug in it that hasn't leaked either. The only down side is having to change your oil. I put an inch of wire off the sensor onto a spade connector. For oil changes I just unplugged it and it spun off. Annoying, but it worked. |
