G5 Oil Leak
« on: November 11, 2010, 10:57:28 PM »
I just completed the first oil and filter change on my 2010 G5 Deluxe after 350 trouble-free miles. (I used Amsoil 20W50 full synthetic.) I then rode the bike for approximately 50 miles. The next morning, I noticed a small puddle of oil on the garage floor under the engine. When I looked under the engine, I discovered that oil droplets were forming on one of the two retaining bolts for the cover over the filter screen (i.e., the rear-most bolt only ..... the other bolt was clean and dry). Has anyone had a similar experience after an oil change? Any idea what might be causing this oil leak?

The lack of thread sealant on the bolts?

Could be a pinched O ring.

Mine leaks a few drops, just like yours, keeps the rust away.  I just put a pan with kitty litter under it and call it good.

You like me are using full synthetic which is fairly more thin than all them dead dinosaurs.  Perhaps a little bit of sealant is in order.

I'm using Mobil 1 full synth 10w40, no leaks.  Full synth is more prone to leaking from small gaps than dino oil but first I'd suspect a pinched o-ring, loose bolt, or tiny piece of grit somewhere on the sealing surface.

Of course to check this you'd need to remove the cover which would drain all the oil. :(  If you don't want to buy new oil just get a clean aluminum disposable baking pan at the grocery store.  Then you can collect the oil and put it back into the engine if you want, without the contamination of whatever gunk live in your normal drain pan.

Scotty, are you sure that ALL the oil would drain out of the oil filter cover?  Isn't most of the oil lower down in the motor?  If the bike is on the side stand I would think that removing the oil filter cap would not cause an exodus of oil.

But, please correct me if I'm incorrect here.  Thanks.

Not sure, but if you used a small pan, then yes, I'm sure ALL the oil would drain out.  If you used a large pan I'm sure it would only be some. ;)

Remember that before the oil change there was no leak. It relates to something you did or didnt do. My guess is an O-Ring pinch as well. Use some grease to hold them in place while you replace them.

My AVL engine with 3 drain plugs and a British design oil filter, don't leak a drop.

Problem solved ..... however, I'm still not sure what caused the oil leak. Maybe the original O-ring did get pinched, as several of you suggested, but there was no evidence of that.  Nevertheless, I replaced the O-ring and slapped everything back together.  I'm happy to report that, after 60 miles of riding, the bottom of my engine is clean and dry. Thanks very much to everyone who responded to my post with suggestions. The US RE Community is fantastic.
