    Ok i have just done a search and read every thread mentioning oil gauges and still have some questions. I want oil temp and oil pressure gauges that match and pref in degrees C rather than F. i dont want a dip-stick sender, call me picky but id rather weld a sender into the sump plate so there are minimum wires in the engine bay. im thinking VDO as they make good quality, simple looking gauges but i cant find an australian website. before i buy anything though i have a few questions;

    a) what range of pressure do i need?
    b) what range temp do i need? i was thinking 0-150
    c) can i just put the pressure sender where the original one was or will this mean the idiot light stays on all the time?
    d) does anyone know where i can get gauges in Australia?

    has anyone bought gauges recently? where did you get them and what did they cost? any help much appreciated.

    since you are looking for standard units you should be able to get gauges from your local spare parts/auto shop along with the sender units

    just the wiring to the sump plate would be exposed and would need to be high temp cable

    Mine is only a temp. gauge, but works prefect and is wired to the sump plate with the sender welded in. The gauge is C made by VDO 0 - 150, placed in the spare hole in the dash console. Works Great. Installed by local VW mech.

    Do a search for VDO Kienzle (?sp) dealers in your state and pick up a 50-150 deg C guage and sender to match - there is some conjecture about the sender being in the sump plate as it sits out in the breeze and may be cooled by passing air - and also a bit vulnerable for lower clearance

    my mech recommended to put it in the oil pressure relief valve 'screw' (the one nearest the rear of the vehicle in my 1600DP) - before if was filled with oil the 'screw' was taken out, drilled and tapped and a new sender screwed in - once installed it sits up a bit out of the way - just need to sort out a good way of routing the wire

    Good to see you have found that you can get the dual sender for pressure guage and light - fits in the same hole as the standard sender

    just a quick update, i rang around today and spoke to 4 reputable vw parts dealers about vdo temp gauges and senders and surprise surprise got 4 different prices:wtf: . had quotes from $92.50 + postage (Mick Motors) to $130. i stopped in at repco just to check what they could do them for and they have ordered in a sender and gauge (be there tomorrow) for $84. moral of the story.... ask around and you can save $$. one of the mechanics (german specialist) i spoke to today also told me not to bother with a pressure gauge. apparently not worth it as he said the "idiot light" is all you need, any comments?

  13. 50-150 VDO gauge with matching sender. Put it in the plate on the sump at the rear(fanhousing) of the motor. My van is low and have never even looked like hitting it. A lot of other things hang a lot lower and will hit first. For oil pressure buy a brass T piece and put the idiot light on the side branch and run the gauge off the top branch of the tee. Idiot light only tells you when you have no oil pressure at all and by then it could be all too late(especially on the freeway). Rather have a gauge to monitor oil pressure as you can see it dropping and turn engine off before damage is done. Idiot light will only come on once no oil pressure is detected.

    steer clear of dip stick temp senders. the give false readings especially when cornering as oil surges away from the dip stick and gives you incorrect readings. they don't stay in the oil all the time.

    Sprint Auto has an excellent oil temp gauge with sender-$65.00- had to buy the thread insert -$6.00-which I fitted (braised) in the small sump plate and then ran a single wire to the gauge which I fitted in the spare hole where the clocks sometimes are fitted -temps range from 90-115

    Why an oil temp gauge Matt.
    Wouldn't a CHT gauge be a better option?

    I used to have a sump plug oil temp sender on the '69 but was never very happy with it.
    It might have been because of its exposure as jb4845 has pointed out, but it didn't seem to accurately reflect what was happening in the engine.
    I'm not a fan of dipstick senders either. My bus "felt" like she was running hot yesterday but the dipstick didn't seem too hot when I pulled it.

    I'm going for a CHT gauge when funds allow.

    I just took my girl to Conti's at Bribie Island vw specialist and he advised me to get neither as it just freaks people out:eek:
    He said listen to your engine and you will smell her when she gets hot. I also should mention I know nothing about any cars and have only had my Kombi for a month but just thought I would feel special because I could add something in in this section as this was something I discussed when I took her for a service
    :lol:

    My old mechanic would say much the same thing however ........he would be able to hear very subtle changes in the engine, never drives above 80 (no never), wouldn't drive it if it was too hot outside (why would you bother) and never no never would listen to the radio .......because he likes to listen to the sound of a well tuned and well maintained engine.
    Us mere mortals on the other hand need all the help we can
    As a doctor I can give an anaesthetic to a patient and keep the patient alive by watching the chest go up and down and looking at their colour .......... but wouldn't you want me to check with my monitoring that they have the correct amount of oxygen, they are not having a heart attack and the patient is actually asleep?

    I have heard the same thing about not fitting a guage as it will freak you out. I have oil temp guages in both kombis. The sender located near the bottom of the cylinder in a specially tapped hole. After driving a while you get used to where the temp normally indicates. If the indication is not what you would expect for the conditions at the time I would stop regardless of the actual reading. For example I would think things abnormal if the guage was showing 120 in mid winter at -4C in Canberra. 120 mid summer at 40C would be OK. Generally 100 in winter and 120 in summer are what I have found to be indicated. Must not be too bad as I have 200,000 ks on the engine. I make sure that it is maintained at the normal periods for service. The engine is a 2l air cooled and still going strong.

    sorry Ray i missed this. cht would be better but its the cost. im just a poor student and the sc was meant to be a quick on the road job (aren't they all). i think as long as you understand that the gauges are not perfect they still serve a purpose. i dont need to know the exact temp, i just need to know when the temp goes up. so an oil temp gauge should be fine.

    I installed my sender and gauge the other day and have to say im very happy with it all. the gauge was wired up when the auto electrician fixed up a few things for me so i just cut the hole in the blank-out plate and then painted it to make it look cleaner.

    here is the gauge in the dash
    [​IMG]

    it looks really good in the dash, obviously sticks out a little being a bit more modern but i found some glass from u-pull-it to cover the face and it makes it look much tidier.
    [​IMG]

    getting the sender unit in the oil sump plate was the hardest part of the whole process. the thread on the unit is a special plumbing thread so i called in a favor and the guy who makes all the tools for my dads plastic factory made and tapped a fitting for me. i forgot to take a pic of the fitting but it was quite simple. i had to grind it down to fit in the bottom of the engine and had to trial fit it 5-6 times before i was happy with the shape of it. then i driled a hole in the sump plate and then dremmeled (sp) it out to the correct size. then i after many trial fits i braise welded it to the inside of the plate.

    [​IMG]
    you can see in this pic that i got a little carried away with the rod. its been 5 years since i did any oxy welding but after ten minutes i was very happy with the result. once the welding was finished i hit it with the wire wheel to expose any holes and clean off any crap from the welding process.

    now in regards to the argument that sump sensors are exposed and can be ripped off if you bottom out i took this picture.
    [​IMG]
    the only part of the sensor that is not higher than the lip of the sump plate is the push-on tab and even this was bent slightly to raise it once installed.
