The one I took off was sitting on the bench.  So Idk, frame in the way?

Also when serching for the banjo bolt, subaru TD04 keeps coming up as a hot word.  And one hit has some really nice over sized holes in it.

I'm going to go to Autozone and ask for it.
May need to get one for the water coolant line of a subaru TD04

Just saw this on ebay...



Looks like the sv650 banjo bolts are special, and might fit the case of the LS650.  The straight ones looks like the ones that came with the sv1000 oil cooler.

"In my opinion, the cooler should be mounted low, even with the foot pegs.  This means that when shut off the oil level isn't going to change.  And air flow to the cylinder isn't blocked either. "

If I understand correctly, the danger is that with the oil cooler fitted too high up, the moment we kill the engine all the (hot) oil will drip down into the sump, overfilling it.
We would then restart the engine with an overfilled sump (very bad for case pressure) and we don't know if the oil would even make its way back into the cooler (which is too high up, hence full of air)

By fitting the oil cooler in line with or even lower than the oil sight window, the cooler would NOT empty into the sump, nor could the sump empty into the cooler... because it's already full !  

Did I get this right ?  

I am not sure it is worth worrying about the oil draining back into the sump, as the amount of oil contained in a cooler for the Savage and the related plumbing is not going to be significant.  I bet you won't have more than an extra pint in the whole cooling system.  The only down side is that if the system does drain the oil out - until that oil is replaced......there is no oil flow to the cam. This should not be a problem as it will only take a few seconds for the refill, and the cam should have some oil in place from the last time it was run as long as you have not tipped the bike over on it's side and drained the oil out of the little recess beneath the cam lobes.  This oil drain back situation occurs whenever our engine sits a long time even without the cooler, and the oil will drain from the passages in the cylinder, engine case and head and the oil pump has to refill those passages on start up (unless there is a check valve somewhere that I don't know about).

You can get check valves for oil flow.  Triumph motorcycles have problems where the wet sump oil tank can drain completely down into the sump - so they install a check valve to prevent this from happening.  It would probably work fine in a cooler installation, as the Triumph passes all the oil through the valve by gravity when the engine is running, and the Triumph most likely pumps a lot more oil than the Savage.

It would allow you to mount the cooler wherever you want and you don't have to worry about anything flowing back down through the oil pump and into the sump.  You really don't need to worry about draining the cooler and lines during oil changes - the little bit of oil will not contaminate the new oil much.

You also need to mount the cooler so that the flow enters the cooler at the bottom, and pushes the air out the top as it is filled with oil.  If the oil enters the top - the air is not pushed out of the cooler and the oil will not flow properly, and the oil will just drip around the air bubbles and the cooler might restrict flow and it will not cool well.

I always hated the Ford truck oil filter over the right side of the K member.  There is no way to catch the oil in a pan.....as it drains into about 6 different streams off the frame!

Yep.....You need to buy one of those little blue plastic swimming/wading pools that they make for kids......if you want to catch the anti-freeze coming out that drain and splashing all over the plastic shielding and frame.

Yea, thats a great plan, but all I wanted to do was lower the radiator coolant level enough to be able to add back some 100% antifreeze. I was getting ready for a cold snap & it was only good down to 20*. This spring Ill drain it all & put new in,
