Topic: Tech question? really it is!

The leak appears to be coming from the thread area, so how do I seal that?

[eldar]

Well mike said to use teflon tape. Make sure it is able to handle high heat. You could also use a high temp rubber washer or 2 probably.

[Jim Shea]

Ta, teflon tape sounds good, and easy to apply. As I said earler, it is only a tiny oil leak so not a serious prob!

[dusterdude]

jim,use teflon something so k8 guy will hush up

[eldar]

Hey we K8 guys hate being right and having to correct everyone all the time!

[dusterdude]

hahahahahahaha

Oil pressure sensor.  Base of unit will not be flush with engine case when full seated.
It should be snug but not overtightened.  Oil pressure sensors can leak through the sensor itself and and not necessarily at the threads.
Take out your sensor and take it to your local friendly autoparts guy. Smile and shrug and say you don't have a part number. Just ask him to find one that looks like it and check the treads to be sure they are the same.
Honda parts guy wanted about $30+ for one for my CB550, and he would have to special order it.
Local Bond Auto Parts store found one for me in less than 5 minutes and cost about $10.

External dimensions and fit are easy for the parts counterman to match up.  I'm sure he's glad to take your money and move merchandise through his store.  However, the pressure calibration for when the switch activates can't be verified by simple visual comparisons.

Does your new switch activate at 2 PSI, 5 PSI, 10 PSI, or 20 PSI?

Were it me, I'd stick to the Honda switch so the system will work as intended.  I think the extra $20 is worth it.

Good luck!

TT,
As a novice I think it is a good idea to stick to stock parts!?

[Bob Wessner]

Were it me, I'd stick to the Honda switch

I'd be inclined to agree. What would it change though as to how the system works? The oil pump gens the pressure and that's not going to change. What will change is what pressure you think you have at the low end right? Might see more lights or flickering of light at idle if the switch is set to 10 lbs min. and the pump is only generating 7 lbs at idle for example.

As long as you equal tghe specs of the old outdated honda unit, you can use a new one. A sensor is a sensor as long as they meet the same requirements.

[dusterdude]

wow eldar!!!that was a very astute observation,the bad thing is i happen to agree

[eldar]

Ahh man not again! Ok as long as our sensors look different ok.

[dusterdude]

Ahh man not again! Ok as long as our sensors look different ok.

ok,cool with me

OEM vs aftermarket oil pressure sensor:
The difference in pressure at which a OEM and an aftermarket switch open is probably insignificant.
Most of these oil pressure sensors switch at very low pressures, meaning that the oil warning light doesn't come on until you have very low (or no) oil pressure.  So the oil light comes on when you don't have enough oil in the sump for the pump to pick it up or the pump is simply non-functional.

Thats about it. How it looks and who makes it does not matter if it meets what you require.
