Gas in the oil

I have been getting gas in my oil on my 82 GS 850L. I put a new pitcock in thinking that was the problem. Any suggestions on how to fix this problem? I've been thinking that the carbs might need rebuilt.
 
Hi,

The new petcock should have fixed this issue. The other cause could be bad float valve seals in the carbs.


Thank you for your indulgence,

As said.. petcock should have sorted it out, but it does sound like leaky float valves as well..

have you checked fuel does not flow from the tank with engine off ??

There is a small amount of fuel in the pipe, that could be working down past the float valves when not running, and although small, over time will build up in the sump.

You can change petcocks until the kaws come home. If the float needles are bad the problem will remain.

DO NOT TRY TO START THE ENGINE UNTIL THIS IS FIXED!

One or more cylinders may be filled with gas and when the piston hits the fuel it will hydrolock and potentially bend a rod.

at the risk of oversimplification, please be sure that you are setting the lever (manual petcock) in the correct place (prime, res, on, er whatever) and you are turning it off when you park. If you don't, this could be where your fuel is dripping down from. Ask me how I know :-\\\

Ok, I'll ask cause I'm very confused. :o
I thought the pitcock was a vaccuum (on demand) pitcock and when the motor is shut off the fuel is no longer flowing. Therefore the reason why theres no "off" position on the pitcock. :confused:
 
Hi,

Yes, the "PRI" (Prime) position on the petcock is the only setting that should let fuel flow (via gravity) without vacuum being applied from a running engine. The "ON" and "RES" positions should not allow fuel to flow if the engine is off - No vacuum, no fuel flow. This information should be in your manual. Here's a little more info:

Where Do These Hoses Go?


Thank you for your indulgence,

I have a related problem.

My bike has been flooding after sitting over night. This all started after I had the carbs apart for an unrelated issue. Can someone remind me what position my vacuum petcock should be in? I remember messing with it but don't remember where it was before. Someone remind me?
Thanks.

Bike is an '80 1100E
 
Mr. VP1,

Read my post above, click on the link, and read some more. :D

Normally you will have it in the "ON" position. If you run out of gas, put it in the "RES" position and go get some gas. Use the "PRI" position if you need to fill the carb bowls before starting your bike. Low fuel levels in the carb bowls can occur from evaporation (if left sitting for a long time) or if the bowls were off for service and have been emptied. If you have one of those dreaded 1980 screwdriver slot petcocks, then all bets are off.

Here's more info:

The other issue to keep in mind is that if you replace an old petcock, bits of corrosion from inside the old petcock have probably already made their way down to the needle valves in the carbs, and some of this mung may remain to prop open the needle valves.

This is almost inevitable if you move a petcock's lever for the first time in twenty years -- the crud from inside the old petcock gets loose and will cause recurring problems (even after you replace the petcock with a new one) until you also remove the carbs and flush and clean the fuel line, fuel passages, and needles and seats.

It took a while to figure that one out the first time I saw it... :mad:
 
Thanks. I found my petcock in the vertical position when it should have been horizontal. We'll see if that helps :)
 
Thanks for all the help, I was afraid that it was the carbs. I guess that I need to work on them and again thanks for all the replys.

on the stock vacuum petcock, this is correct, the fuel will only flow once there is a draw.

I was talking about a manual petcock.
