Engine/Transmission (1994 - 1998) Oil pressure gage

[J.R. Adkins]

Where can i tap in to easily to run a line for a mechanical gage?

I have Isspro gages now, do they make a gage for this application? Anyone have a setup like this?



TIA

There is a plugged 1/8" pipe thread port on top of the oil filter that is excellent for taking oil pressure or temp.

Don't know about your other question.

Thanks illflem,



For some reason I knew that you would be the first to reply. Seems like you are always lending a helpin hand! Thanks!

Ditto on Bill's post, great location. Here's another idea, tap into the 1/8" port, using a 1/8" NPT T fitting. Cap one port, use the other for your pressure gauge. When/if you want to use another gauge for oil temp. , remove the cap, screw in a bored out male to female 1/8" NPT adapter ( needed to set the sender back from the inside of the T fitting), place your temp sender in that port and you are all set for a oil temp. gauge.

Here's my $. 04 worth...



I would NEVER run a mechanical gauge with that lame plastic tubing... that stuff is too unreliable for a VERY vital fluid in your engine. Run an electric gauge with the sender right at the source... . you'll never have hot engine oil in your cab or anywhere it's not supposed to be.



I've fixed those crappy lines on other cars/trucks too many times to EVER have on one anything I drive.



It'll cost more, but it's worth it. . IMHO.

Matt, I don't know, I've run mechanical gauges for 40 years and have only had one leak, plastic or copper. I've had several electric senders leak though. The only tubing that leaked was on a dump truck that had been parked for five years, rats got it. You do have to use some common sense, don't run plastic tubing over sharp edges or hot manifolds. All in all mechanical gauges are more reliable and acurate.



Here's a good one- a couple of years ago someone posted here about an oil leak under his dash. Turned out the sender was leaking and the oil was traveling into the cab in-between the wire and insulation of the sender wire.

I've heard of the oil coming through the wire quite a few times..... I can't remember for the life of me what the application was, though... . These cases were a lot more rare than mechanical gauges, though... .



It's a tough situation... . I'd like to know what's going on... but I don't have enough faith in compression fittings and nylon tube to be running a vital fluid through it. Granted, I could stop and fix it if/when it breaks but that's one more thing to fuss with.



It's the old good luck/bad luck situation. Some love them, some love to hate them.....

Well, I'll argue the reliability and accuracy issue with you. Yes, you're right for the cheapo two dollar crap sensors they put on most automobiles, but "real" pressure transducers are, in general, far more accurate and reliable than mechanical guages. They also don't have the leak problems with the cables, etc.



But, you've gotta pay for 'em. For example, here's some "cheap" ones, only 1% accuracy and a mere $225 http://www.omega.com/ppt/pptsc.asp?ref=PX178&Nav=preb03

And that's just the sensor. Now, for more accurate versions, you can look at some of Omega's other sensors up in the $1k range...

... . those are nice, but pricey.



I'm on a need to know basis with my engine. I do what I think it should need as far as maintenance and operation parameters and it only tells me it requires things when the dung really hits the fan.
