it probably would but would it be accurate?
how do you know they all have the same resistance vs temp curve

[CJH]

True - I don't. But I only mentioned it as an option, for completeness

I like your option, and I'd be tempted to do the oil filler mod anyway, even without adopting your temp sender approach.

[CJH]

Actually, if you could devise a mod to use the oil pump mounting points I'd be even more interested. Mine's blanked off because I fitted an electric fuel pump, and from memory it would feed directly into the sump. It'd need some kind of reducer to fit the plastic filler pipe I think, but I'm sure a man of your calibre could sort something

[CJH]

Did I say oil pump? I meant fuel pump of course.

[itchyfeet]

yes that would work too^^^ but you still have the expensive to replace usually broken oil brether tower that you can't clean the mayo from problem.

I asked Mr. Baxter a while ago about the location of a temp sender unit in the sump because it's not something you'd ever see on heavy plant due to the sump dissipating heat like a radiator. I wasn't convinced by his reply (no offence meant by the way). Of all the places to record a measurement, why would you do it there?

oil temp will vary in the system for sure

yes it may be 20 degrees hotter in the main galley but who cares?

Its only comapible if we all measure in a similar way which is only practical in the sump as close to the main volume of oil as possible.

Looking good Paul.
I like your ideas here.

All the breather towers I have ever seen are long since broken, the rubber membrane has perished and it is no longer a valve just an open breather so no loss cutting it open.

That expains why I get oil spitting out into my air intake.

Too much and you have to question if you have worn or broken rings, you should only expect oil vapour.

How about taking a reading from the oil pump location using a washer type thermocouple -

I'm just informing you of other applications and reasons why they don't use this location. You could always join the even more fanatical forums frequented by Caterpillar lovers and ask for their opinions.....

measuring on the outside of the case is not measuring oil temperature, my pressure relief valve location is essentially doing this but in winter this area stays colder than the oil because it's so well cooled by cold air from the outside.

[itchyfeet]

This is the breather valve somebody ( maybe CJH?) suggested to me a couple of years ago that I never fitted, got the 19mm silicone hose today part number 06A 129 109 D I think it's the right way around.

more breather tower geekyness

you can suck on the valve and get flow but if you suck suddenly and hard it restricts flow

I have fallen out with my oil breather and now have the breather inlet on the air pancake blocked off. My breather tower now feeds into a separator / collector can and vents to atmosphere. This has made it easier to control the Lpg mixture.
