Mi16 Steel Engine

[mmt 15]

Just received a steel mi16 engine. The sensor layout/sensors location is diffrent from the alu mi16 engine I had installed before.

 

Could anyone tell me which sensor is which.

 

On the alu engine the oil pressure sender and the low oil pressure warning swich is two different sensors positioned right next to eachother on the steel engine it seems that there is only one sensor!? or am I wrong?

 

I´m all new to the steel engine any help apreciated.

 

Thanks

Yes there's only one tapped hole on the front of the block, isn't there ? I guess they used a combined switch/sender, I discovered this when I moved to the iron block. I would just get an aftermarket T-piece adapter to put in there so you can run both of your old senders/switches out of the one hole.

Correct! Only one hole.

 

Which one of the two sensors of the alu engine is the pressure sensor and wich one is the warning lihgt swich?

 

Is the "big" bell like one the warning light swich? And is the "smaller one" the pressure sensor that delivers input to the pressure gauge?

 

Thanks

I always thought it was the other way round, the small one was the switch and the big one was the sender, but you got me wondering there. So I checked on the parts CD, and it shows the switch as a smaller style sender, and the gauge sender as the larger one - whether that's accurate or not, I don't know?

I´ll look it up in my Haynes.

 

I already has a t-piece and a aftermarked warning light installed. The aftermarked warning light is installed together with the "smaller one" of the two sensors. Hoping for a shortcut!

Yeah, I'd double-check that. I'm not sure I trust the diagrams on the parts CD. I've had aftermarket warning switches before and they've come with the larger-style 'senders', so I'm wondering whether you're correct now.

 

I Haynes'd it too, it seems early models only had a pressure switch (maybe no gauge, just a warning light?) while later models do indeed have a combined sender with two connections on, one for the warning light and one for the gauge. Haynes is a little confusing though as it doesn't really cover it in that much detail.

 

I'm sure someone with 1st-hand experience of what 405's had in them can maybe comment (or ZXs, etc)

The larger-style 'sender' are for the pressure gauge and the smaller one´s for the warning light.
