Ive been attempting to finally get my mechanical oil temp gauge fitted to my mpi with out any success.

Is there a 100% fool proof solution using a particular gauge and adapter and NOT having to fit the sender in place of the sump plug?? The magnetic sump plug does play an important role..

So far with the current mechanical smiths gauge its just not working out. I have the oil pickup adapter plate wich fits at the back of the gearbox however the gauge sensor is very long so i also needed the sump plug adapter so that it doesn’t block oil flow. Next problem as a result is that the downpipe cant be fitted with it in place as there is no clearance ?

All help will be much appreciated and I look forward to finally having a working and accurate oil temperature gauge.

I would have got a fitting with the correct thread so you don’t need an adaptor.

 

so either have that fitting machined. Needs engine splitting to remove it.

 

block it off and fit it somewhere else.

 

get a different temp gauge.

You can get one of these Mishimoto sandwich plates:

Couldn’t you have used the existing oil temp sensor location - that’s what I have done on my MPI (but it’s electric)?

Even with backing plate with the correct thread I would still need some kind of extension as the capillary is very long and would limit oil flow.

Ah nice, will investigate this route! However I do have limited space as I already have an oil cooler with the Mocal sandwich plate fitted and a large alu radiator for water cooling.

The threads here are different, and I would like to keep the original temperature gauge.

After scouring the internet for a solution to fitting a mechanical oil temperature gauge I have decided to give up on it and go with an electric gauge. I didn't realise until checking the owners manual that the temperature gauge in the speedo cluster is actually the water temp and not the oil temp. So I will hook into the original temp sender and fit an electric gauge. I would have preferred a mechanical one, but oh well, i've wasted to much time on this and theres no way I can easily fit a capillary anywhere to the engine.

I can't believe however how little information there is on this subject as it is a pretty common thing to do. What is also frustrating is how all mechanical gauges advertised online do not list any specifications on the capillary about size, thread, etc.
