Where do your temperature and oil pressure gauge needles usually sit?

[nickolai]

I have both the stock and Autometer (oil pressure, water termperature and RPM). I wanted the most reliable info on what the 2F was up to. Turns out the stock gauge was showing overheating when actually things were humming along at 190F.

My take on it is that we're talking about old trucks here - and old electrical systems too. If they work - sweet as, but chances are that the senders, wiring or the gauges themselves are beginning to succum to old age.

I'm one that isn't fond of the stock gauges Tom for 2 reasons, 1/ because when your subjecting the truck to steep angles eg: the pic's below you want to know exactly how much oil pressure you still have before the engine starts starving of oil and you cant get that sort of accuracy and reading from a stock gauge compared to a good quality mechanical gauge and the same goes for the engine temp when your radiators filling up with mud and the trucks getting hotter and hotter you want to know exactly how hot the engines getting rather than relying on a stock gauge that's probably got a big flat spot through the centre of the range and 2/ because the stock gauges are too small and hard to read when your competing or doing some hard 4WDing you cant afford to take your eyes off where your going to try and read the gauges properly and I probably couldn't do it anymore without some reading glasses anyway so I've got 2 Autometer 2 5/8 mechanical gauges sitting right up at eye level in the windshield where they are always clearly in my vision. The stock gauges are fine for everyday stuff but when you start pushing things a bit further you need some more accurate readings to try and minimise engine damage and/or failure

LOL. These arguments will be with us forever Marty... And I admit that if I was subjecting my cruiser to competition events I'd probably look at a few things differently.

BTW - I'm sure I spotted you in Karori Rd a few weeks ago headling towards town while I was trundling out to Karori Park in one of those trolley buses taking the city workers home. There can't be many soft-top shorty's with burbling V8s left that are road-legal. ... I was admiring the very nicely balanced stance/appearance etc.

Next time I see you on the road perhaps I'll have enough time to flash my lights, honk my horn or swerve into your path (to grab your attention and maybe even wave a greeting)...

....hey Tom that would be great if you compiled a list of gauges to owners manuals

Quite true. 30 years is enough time even for quality products to develop faults..

Don't rely on your 40 year old gauge to be correct. That being said your taking more of a crap shoot using a mechanical oil pressure gauge with the small poly hose. Do yourself a favor and spend the $10 and use a copper line. Especially the 76 and older motor crowd. Those poly lines will fail and spew a death trail leading you to a seized motor. I've rebuilt two customers motors in the last two years because of this.

What I now do on all my motor rebuilds is install a dummy light that comes on at anything lower than 20psi. You will actually see that. I can assure you when you lose oil pressure you won't be looking at the gauge. And it only takes a few seconds of no oil pressure to be to late.

Yeah that was probably me Tom its not driven on the road very often but I've had it up in Karori a bit lately doing a bit of data logging on the ECU to re-tune the fuel maps its a bit easier to do it up there the roads are straighter and I can drive more constant to get better data logs rather than the skinny windy road down here. My red FJ75's more likely to be seen on the road but that truck isn't as unique looking as the FJ40 so it tends to blend in with the traffic an bit more and go un-noticed. Will have to have a catch up some time and talk and compare cruisers
