Seedy Al Posted November 15, 2012 Share Posted November 15, 2012 I may have asked this before, but on my VW, there are pretty much no gauges, and so far that has casued me a problem with over heating my engine more than once. So what I'm looking for is a combination of an Oil Pressure gauge, and Oil Temp gauge. Does anyone know if I can use a water temp gauge as an Oil temp gauge? If so, this would make my life alot easier, as it seems easy to find a combination water temp, oil pressure gauge, than a oil temp specific gauge? Any help would be awesome I have just got the VW running with the second hand motor, and want it going for as long as possible hearts Allan Quote Link to comment Share on other sites More sharing options...
AllTorque Posted November 15, 2012 Share Posted November 15, 2012 How hot does the oil get. Would a water temp guage read high enough? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 15, 2012 Share Posted November 15, 2012 I assume you mean an electric gauge rather than a bulb style gauge.. I would say as long as the sender is calibrated correctly then no reason why not. edit - and of course providing the gauge goes high enough - oil temp gauges can go as high as 140 but most water temp only goes as high as 120 Quote Link to comment Share on other sites More sharing options...
phtmbl Posted November 15, 2012 Share Posted November 15, 2012 i have prob got a spare oil presure and temp gauge set up from the gto if you want one (electric type) Quote Link to comment Share on other sites More sharing options...
kiwi808 Posted November 15, 2012 Share Posted November 15, 2012 Hmm bit of topic, but I thought that for every pond of pressure you put into a radiator you raised the boiling point by 3degrees. which meant your average 13psi rad cap meant your radiator water was 139 degrees? What kind of oil temp gauge do you want. Surely you can get them from super cheap or something. My old 808 had seperate oil temp oil pressure and water temp gauges and I got those from reppco back in the day. Quote Link to comment Share on other sites More sharing options...
Ogre Posted November 15, 2012 Share Posted November 15, 2012 Used a water temp gauge as a oil temp before. Works fine.Guess you just need to make sure it goes high enough. I cant even remember how hot my oil used to get but it never went off the gauge or anything. But i do remember being surprised how hot it DIDNT get. I think placement of the sender would be important too. I had mine in the side of the head. Quote Link to comment Share on other sites More sharing options...
kiwi808 Posted November 15, 2012 Share Posted November 15, 2012 Also a water temp gauge in a VW would be quite funny. 1 Quote Link to comment Share on other sites More sharing options...

Yes it raises the boiling point but it does not raise the temp in the rad. Quote Link to comment Share on other sites More sharing options...

kiwi808 Posted November 15, 2012 Share Posted November 15, 2012 thats why hes asking if it can be used as an oil gauge.... I figured that out after I had make several posts. Because I am slow. *palmface* Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted November 15, 2012 Share Posted November 15, 2012 egt gauge? Or is that more a diesel turbo one? Quote Link to comment Share on other sites More sharing options...

Seedy Al Posted November 15, 2012 Author Share Posted November 15, 2012 I think this might be for a plane though, so not sure if it works on 12v I hate the style, but its one of the few combo gauges I have found. The reason I want to use a combo gauge is that there is already a none working temp gauge in my cluster that some one has installed at some point, but has no sender unit?? SO figured I would get a cmobo gauge so I know what the pressure is doing also, and dont want multiple gauges hanging out all over the place, its not a race car after all and certianly want electric, as running 19 foot of oil line to the front of the car is not something I'm keen on doing, even though I found a guage I actallu liked that did this, that was mechanical. It stated the fluid temp could be used in oil or water. Should the oil temp gauge be mounted in the sump as a general rule?? this would be a problem if it is.

AllTorque Posted November 15, 2012 Share Posted November 15, 2012 Sender normally goes in the sump but I have seen them in drain plugs. Quote Link to comment Share on other sites More sharing options...
0R10N Posted November 15, 2012 Share Posted November 15, 2012 Maybe this guy will relist his combination pressure/temp gauge? http://www.trademe.co.nz/motors/car-parts-accessories/performance/gauges/auction-528125324.htm warning: it's JDM though Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted November 15, 2012 Author Share Posted November 15, 2012 hmmm. guy seems a knob, but yeah, sounds maybe perfect, tho it sounds mechanical..... Quote Link to comment Share on other sites More sharing options...
oldrx Posted November 15, 2012 Share Posted November 15, 2012 0-120 degrees & 0-160 psi Smiths dual gauge - supposed to be for oil and water almost at bottom of page http://www.gaugeguys.com/Smiths/classic.htm Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted November 15, 2012 Share Posted November 15, 2012 yeah tyou want it 'swimming' in oil to get a good idea of what's happening. I'd make a way of running an extra gauge if it were me, run two gauges. the kids will love you for it. Oil gets up over 120 degrees, as KK said, that's why their scale starts with a higher base temp i suppose. Quote Link to comment Share on other sites More sharing options...
DB8-TypeR Posted November 16, 2012 Share Posted November 16, 2012 Can you get sandwich plate to go between oil filter and block? Thats where I have my oil temp and pressure senders. Have had oil temp up to 140degrees on the track so seems to be a decent place to tell you oil is getting hot Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted November 16, 2012 Share Posted November 16, 2012 ^that's a good idea. problem with putting in in the side of the block or head is, you may only get a splash of oil now and then/not constant, so essentially you're only measuring the temperature of the air in there/the block itself. oil filter always has oil going through it, so, win!
