do I need to empty all oil for valve adjustment?

I cant understand people putting old oil back in a 40,000 dollar minimum appreciating asset car.

Why not just do it at oil change time and avoid all this putting old oil back in your car malarkey.

well... I think the same way you are thinking. I was only about 300-500 miles on a complete oil change before having to do my valves... seems like a waste of extra time and money to change the oil on top of everything else needing to be done.

Also... if I DID change the oil at the same time of doing the valves, and the next day found a problem that required me to redo the valves, I'd hate to change the oil again in just one day!!! That's about a $100 cost.

Malarkey is in the eye of the beholder, as I consider needlessly throwing away perfectly good oil to be malarkey (same thing with silly, 3K mile oil changes). And if someone can't drain oil into a clean container and put it back in without adding dirt to it in the process, they have no business working on cars.

I've removed all valve covers without draining the oil, it's fine. no more than a few drips of oil lost. I had the same concern, asked a few friends and was advised that you don't have to worry about a large volume of oil sitting in the valve covers.

I jacked car on one side, and no oil came out.
