Additional Oil Temp Gauge Questions???

[Antonn3]

FYI-
the 2 side plugs are M20-1.5 threads (certain years of Subaru engine plugs are the same) and the one facing forward, behind the exhaust pipes, is M16-1.5 thread.
The one plug facing forward is more direct in the oil volume, as the side ones are in passage ways  involved in the oil relief valves system.
But any of the 3 plug locations should work as I  think the manuals states the side plug is used to check pressure.
How do I know this...my forward plug broke at the threads and trying to find one that would fit locally was not easy.

Tony, I am never seen a FJ with a smaller galley plug behind the header, and I have seen thousands of them. The main oil galley plugs are all the same 20x1.5mm threads, as can be seen in by Alan's photos posted showing the installation of the 20x1.5mm oil galley adapter in the front facing fitting.

The three oil galley plugs mentioned are all the same direct oil feed from the oil pump, thus they receive the same oil volume. That is the main oil lubrication galley that supplies the crankshaft and does have a pressure relief valve to prevent excessive pressure.

There is a 16mm plug located in the side of the oil pan which is the secondary oil system post used for the oil cooler.

I would be interested in seeing a photo of the smaller oil galley fitting you have int he front of your block.

The Shindy digital unit is very, very easy to mount (no drilling) and works well. I have them on 2 bikes and no problems for over 6 years. Just replace the drain bolt with the correct adapter bolt and screw in the sensor. The sensor has a quick disconnect which makes draining oil as easy as stock. Also doubles as a clock. http://shindypro.com/catalog/each_q_ptype.key23.html

I am probably going to do this project because I can, same reason as I did the bigger oil cooler mod  , and this is one of those neat threads that just makes we want to do it.

but after goodness knows how many years of the the FJ in some reasonably hot Australian summers, I have never had an over heating issue or any performance issues due to heat, the only thing that over heats is me    

so is there any "real" reason for having an oil temp gauge on a big air cooled lump like the FJ apart from the fact that it will look really cool

Always nice to know what is happening. The oil temps certainly rise with more compression and displacement. I will say that there have been several occasions when I wish I didn't have the temp gauge....both involved being stuck in stop/go traffic for about 30 minutes.

Some people just like to keep tabs on their engine's operation....................I am one of those people......even though there is little you can do about it..

It did tell me a couple times, while stuck in traffic, that I needed to get over on the shoulder and ride past the line of stopped cars.....much to their dismay.

Good evening Gentlemen,

When I upgraded my road worn oil cooler with one from RPM, I installed both an oil temperature and an oil pressure gauge. I chose units from GlowShift and have had no problems at all. They both use electrical senders and I replaced the galley plugs with adaptors I purchased from Randy as well.

They are lighted & the nice thing is that they have a 270 degree sweep. To "water proof" them I used dialectic grease on the back of the gauges to seal the connections. It has worked fine after many thousands of miles as the grease does not wash out. The grease also seals out all the road grime that collects as the wind blows up through the fairing (the gauges mount on the small bolts that hold on the clip-ons). I periodically wipe it off (as it becomes dirty) and apply another coating.

I have never seen 300 degrees, even in the hottest conditions when pushing the bike hard. However, other than the occasional traffic back up, I cannot say that I have been stuck in traffic for an extended length of time.

The oil cooler itself as well as all the fittings have remained sound (after many thousands of miles) and the nice ting is that until it gets uncomfortably cold for the rider, the cooler maintains the oil temperature at 180 degrees which does not over cool the engine.

Ride safe,

Mike Ramos.
