I thought that both the heads had blown on my 1977 triked GL1000 K2 type.

When I looked at the water it had a gray oil grunge floating on the top,the radiator, expanssion tank; however when I drained thewater it looked really clean with the anti-freeze been the only evident chemical mixed with it!

When I drained the oil it also looked clean and free of water! I carried on stripping the engine down, first the radiator, radiator fan and the i started on the carbs as soon as I opened and removed the Air filter, I saw that the whole of the air box was full of il the carb were swimming with oil!

Has any off you any ideas on what could have caused it?

Sounds like you have some blowby due to weak rings if you are getting oil in the airbox. Might be time for a rebuild.

What's the bike's mileage? Also, are the breather hoses connected to the airfilter box, especially the crankcase breather hose? Perhaps you have excessive oil spewing from the crankcase and collecting in the box? Otherwise, it has to be leaking past the rings from the engine side and getting in the carbs. On my bike, the crankcase breather hose got blocked and actually backed oil up through the fuel pump weep hole, it was spewing out. Those vapour have to vent somewhere.

I think it's more likely related to either a head gasket leak or a shot water pump that's allowing the water and oil to mix. A leaking head gasket could pressurize the crankcase enough to force oil out the breather, ditto a leaking head gasket. I doubt it's rings, a quick compression check should ease your mind about that.

Was the oil thick like crancase oil or watery.

It is possible that the airbox drain tube isn't functioning and that you have an oily water mixture in the airbox. Locate the drain tube and make sure it works.

As far as oil in the water, if it returns, it's definately a sign of another mechanical issue as has been mentioned.

Engine mileage s 56000. The breather hose is conected to the back of the air box.

I don't think it's getting past the rings! Because when I pulled the hose and let it hang free loads of oil ran out of it. When I lifted the carbs, all for inlet valve chambers were free of oil!

Thanks for getting back to me

Oil was a dark rich colour and seemed to have plenty of body (not watery or burnt out)

There was no water/oil mix in the air box!

There as been oil showing in the top of the water expanssion tank for a while;I've actually bought a new water pump and a full set of water pump seals; which I was going to fit when replacing the head gaskets!

Thaks for getting back to me!

So! do you all think that I should press ahaed with the cylinder heads gasket change?

I tried to crank the engine yesterday, just to see if any oil was gonna spout from the breather, or spark plug holes. She wouldn't turn? I just got a clicking noise for the selonide; so attached jump leads from the cars battery and got just the same again click-click and nothing else?

Could this oil build up affect the starter region of my engine? I'm going to check for continuity today (battery to starter)



Thanks again everyone for your advice

RebuiltYorkie, it sounds like you have two different possible problems there.

A slight oil residue on top of the coolant in the overflow bottle is usually caused by a slightly leaking (seeping) cylinder head gasket, or possibly a water pump oil seal seeping as the engine cools off & the pressure in the cooling system goes negative. It could alsohave beencaused by using a filling container that had oil residue in itwhen filling the radiator..-- Try flushing the radiator & over-flow tank then re-filling with fresh (clean) coolant, then watching it for a while to see if the oily residue on top of the coolant comes back.

On the oil in the air cleaner box? That most likely came from the crankcase breather hose. It could indicate an engine problem like piston ring leakage or more than likely an over-filled oil level or diluted engine oil. Oil in the air cleaner can also come through the vent line if the engine is operated at very high RPM's under a high load for a while.

Try removing the crankcase vent line from the air cleaner then plugging the air cleaner box hole off.. Then take a small plastic bottle with a screw on cap & drill a series of holes in the cap (to allow the bottle to vent through the cap),, Then drill a larger hole in the center of the cap to allow the vent hose tobe inserted intothe bottle.. Tie strap that plastic bottle to the bike some place then just keep an eye on the bottle as you ride the bike. If you keep getting a bottle full of oil you have a problem like overfilling the engine or internal engine problems. You might try going to a different type of engine oil or even trying 20W50 oil to see if that helps. DON'T over-fill the crankcase & check the accuracy of your oil dip stick against a new (proper) fill of oil.
