Looking at getting one of these as the dipstick sender I am using at the moment I am not convinced by and it is a mare to see the oil level on a shiny chrome dipstick so would like to go back to standard. 

Heritage site says it cant be used with deep sumps, cant really see why as the only difference is that as it will read the temperature of the oil being sent into the engine there is less turbulence in the deep section whereas in the top bit it will be getting the oil freshly returned from the hot bits so I would just expect it to read a little lower but benefit from a bit more stability.

Heritage customer service came back with
"We believe the deep sump has a different stud pattern and requires a specific sump plate where this one fits the standard case pattern with a 30 degree offset."

I am certain that I have a standard sump plate on mine and dont really see how having the bolts rotated a bit will make a difference as the mesh filter is fixed with the same bolts so any clearance moves with it.

Anyone got one of these sump plates, sender and mesh screen off the car so you can look at any potential clearance issues before I get one as I am not convinced.

Will probably contact CSP direct for an opinion
Cheers

Just found it on the CSP site

"This product is not made for deep sumps because they are fixed to the engine case with the original studs and their studs for the strainer covers are 30 degrees offset."

I see what they mean about the offset as the sump is fitted by using a long allen key through indents in the bottom hole so the bolt holes have all moved round, but only practical difference I can see is that the fins wont be exactly in line with the air flow, so should still hold the sensor where I want it as that is pretty much cosmetic and any show that stops me getting an award because the fins are 30 degrees out is too anal for me anyway 

Couldn`t you just get one of those T-Pieces and fit a temp sender next to the oil pressure switch

I have a csp sump and vdo sender..

I have never seen it move, at all, ever, apart from one time sitting in traffic on a hot summers day. Otherwise it does not register. I honestly thought the sender/gauge was broken.

I would tee it off somewhere near the cooler/pressure switch/pump area.

That's an idea but need to look for a three way. Already have oil pressure sender and light, could end up like a Christmas tree

Will have a look, probably much cheaper than the CSP plate as well

Always handy to visit a local milling firm, they can make you something fancy to hold all the senders.

machined brass, mmmmmmm

Just occurred to me that pressure is fine in a dead end T piece but for temperature the sender needs to be in the oil so cant work in a T piece stuck out in the air

That's an idea but need to look for a three way.

Or use the Golf / Audi combined pressure and oil switch unit that most of us are using - and use your existing 2 way T piece

Hear what you are saying about oil in a dead end - but should stiill be fairly effective

To be honest I cannot see the temperature gauge working unless it is immersed in the oil flow, that's what I think is part of the issue with the dipstick sender, it spends time in air and splash rather than sunk in the oil.  I might try whipping the pressure sender out and fitting a temp sender in there just to see what happens.  Might go for the combined switch anyway at some point as much neater than a T piece, it will give me an opportunity to try the temp sender there, happy to be proved wrong but cant see it working properly. 

I had an oil temperature sender coming off the sump. Like Apaman never saw it move, tried different things , including improving the earth. Now on an oil dipstick sender. Reads 180-190 when hot, probably a bit low but a least it indicates

Years ago I drilled and tapped a sump plug and fitted a sensor. Did the earth with a large ring connector it worked but was too exposed, that's why the CSP seems a decent solution

Maybe I will tap one into the edge of the extended sump. It can be a permanent fitting there and no disconnecting every oil change.

Job for when I change the oil next

Thanks for all the replies

Just another idea for you, I fitted a sandwich plate at the oil filter and put my sender in that. Had to try 3 different senders until I found one that had the correct resistances to give an accurate  reading on the gauge.

That's an idea, but again would be a Christmas tree, already have a sandwich with feed to the oil cooler, another sandwich and it would be touching the rear wheel (nearly)

Will have a look see what is available, might be able to find something to fit between the feed pipe and oil cooler sandwich

I love my little temp gun can find hot or cold spots and can be used see how close or off your gauge realy is

I've got 3 tappings on my sandwich plate so enough for 2 pipes and the sender.

A bit more information as to how I worked out which sender was most suited to my VDO temp gauge. I connected the wire that comes from the gauge to various different value resistors then grounded the other end of the resistor to earth. From this I could see what temp the gauge read for the different values. On mine  a  106 ohm resister gave a reading on the gauge of  81 deg C
                                                                             55 ohm                                                            99 deg C
                                                                             44 ohm                                                          116 deg C
                                                                             26 ohm                                                          132 deg C

Then I got 3 different spec senders (all supposed to be suitable for a VDO gauge) connected an ohm meter to them and dunked them into boiling water and at as close to 100 deg as I could estimate they gave resistances  of 125 ohm, 60 ohm and 26 ohm so I used the 60 ohm one.
