vapor lock in oil cooler?

[coug66]

I just installed an GS1150 oil cooler on my GS1100. I connected both hoses up on either side of the oil filter cover. My question is can you have a vapor lock in the oil cooler? I Could almost see loosening the return line to let air out so the oil can travel into the oil cooler?

I just don't know if the oil will purge the air out and allow for flow in the cooler?

If you can get a vapor lock on a water cooled engine system do we know it will purge the air without manual assistance?

Any experience or advice on this would be helpfull.

cheers

To the best of my knowledge, vapor lock is usually associated with gasoline in a carburetor.

It happens because there is so much heat when the engine stops, and it will boil off the liquid gas, leaving just vapor. Although your engine thrives on vapor to burn, it requires liquid at this stage to send it through the appropriate jets so it can be vaporized.

You might also get some air bubbles in a liquid-cooled system due to excessive heat boiling out the water, but I have not seen any liquid-cooled GSs yet.

To boil off oil, the temperatures would have to be so high that you would have other problems, too.

In your system, if you have all the proper plumbing for the cooler, it will purge itself. When you installed the cooler, what adapters did you use to get your oil and return it to the engine?

Did you install an 1150 oil filter cover? You need one or oil will not properly flow into the cooler.

Vapor Lock

To the best of my knowledge, vapor lock is usually associated with gasoline in a carburetor.

It happens because there is so much heat when the engine stops, and it will boil off the liquid gas, leaving just vapor. Although your engine thrives on vapor to burn, it requires liquid at this stage to send it through the appropriate jets so it can be vaporized.

Pretty clocse but a bit of a fines point to the explaination; OK Here goes.....

Vapor lock occurs when a liquid boils in the line and a pump can't pump a vapor. Liquids boil when their vapor pressure equals the pressure in the line. If you heat a liquid and it is at low pressure it will boil. If you keep it under pressure it will not boil.

Generally vapor lock is associated with older cars getting hot and the gas in the feed lines from the tank get warm from lack of flow and the gas vaporizes and the pump can not suck the vapor to the carburator . One solution is to push the gas from a pump in the gas tank keeping pressure high and virtually eliminaring vabor lock regardless of heat...... Ask me how I know 12 months of motor home hell with an 81 Dodge 440 Class B....

Before I go any further this has nothing to do with the oiling system or installing a cooler on a GS

You probably have something else wrong.

As Nessism asked, What type of filter cover did you use? Do you have a 16V GS1100E or 8V GS1100G ?
What adapter did you use to plumb your oil cooler? There is a whole thread on this one so it is somewhat of a loaded question ?

air lock

Sorry guys I should have chosen my words more carefully, yes you are coirrect what I meant was airlock.

I have the following system see pictures

Banjo bolts to the two bolt holes on either side of the filter cover.

What about the filter cover? The 1150 cover is needed when you install an oil cooler.

OK From his signature he has a GS1100EZ

That simplifies the issues with the rear adapter.

From the picture it doesn't look like the cover was touched.

Buy a new OEM filter cover for a GS1150 and or do a search for 16V 1100 oil coolers and find out why

I have a black cover but it does not have any holes or threaded holes. It is esentially the same as the one installed.

When I undid the bolts they had oil behind them. I changed the oil and installed the oil cooler at the same time.

The thing went together easily and the metal fitting all worked perfectly. The banjo bolts were compatible. It looked like it was a factory OEM assembly made for the GS1100.

This current setup if working will allow easy access to changing oil filters

I just would have to remove the cover to get to the filter.

I hope this works as installed?

I have a factory manual I just can't seem to find an oil passage channel diagram to diagnose the effectiveness of the current setup?

Has anyone seen something like this in the manual. Most other manuals give some kind of diagram?

Ian

[Nessism]

The 1150 cover diverts oil flow into those oil passages you tapped into. The below photo is pretty small but you need the one with the closed corner so to speak or there will not be a meaningful amount of oil flow into the cooler.

[coug66]

awesome!!! I have the cover and yes it does have a deep recess in it. I will install it when I get the chance. I might wait just a while as I just changed the oil yesterday.

I found this thread regarding the cover.

Thanks for helping me out!

OK Better pics

A better picture comparing teh GS110 v.s GS1150 covers is here. You need the GS1150 cover to make the cooler work.

Sounds like you might be on the way to better cooling

Just did the same on my 1981 gs1100E. I purchased the 1150 oil filter cover and bolted the lines in. I used automotive (GM I think), oil drain plug gaskets with the neoprene inserts on the banjo bolts for NO Leaks. The lines are just another gallery and the seven psi oil pump will fill the cooler immediately. NO PROBS>

Oil Cooler Description

The link below seems to have been updated and gives a nice explaination about GS or GSX (in the rest of the world) oil coolers.

The link describes 16V and 8V solutions. bear in mind there is still come controversy over "the neck" on the 8V solutions.
