03 Ltz 400, on the shifter side there is an oil line that comes to the bottom of the crank case near the shifter, is there an O-ring of seal of some sort that goes in there? Also I filled the crank case with one quart, and put almost 2 quarts of oil in the tank up front, but it does not register on the dipstick. Shouldn't it circulate through there some how, is there some kind of one way valve inside this line? Thanks in advance

there is a small metal sleeve that you put into the hole in the oil line, than a small o-ring slips over it. Then bolt that into the engine case.

The motor with an oil change should take 2.2 quarts. You need to let the quad idle for 3 mins, shut it off and leave it for 3 mins, then check it. Check it just setting the dipstick on top, not screwing it in

So an O-ring goes over the little nozzle like pipe sticking out of the case, than the oil line fits over that and a 5mm allen wrench to tighten it down?

I put oil directly into the top of the case, and than some in the tank, should all this oil circulate through and start registering on the dipstick. Also the engine was rebuilt would it take more oil?

Exactly. Locating pin (the short metal sleeve), o-ring around it, and mount the fitting to the engine case. No o-ring = massive oil leak.

• 2.1 quarts for an oil change (no filter change)
• 2.2 quarts for an oil and filter change
• 2.3 quarts for a full engine teardown

You add it all to the oil tank, not into the engine case.
