Vacuum + AMC V8 = Enough Suction for quick oil-plug WASHER swap?

[Caver Dave]

Oil had 50 miles on it in Nov. and found the plug dripping... have a large variety of nylon/annealed copper washers, BUT... don't want to the whole drain/pour back.

Have seen folks use a vac on various tanks (diesel, hydraulic) to repair/replace drains... given the AMC fill tube fits the nozzle and the crankcase should be fairly tight minus the fixed orifice PCV...

This will only work IF you livestream it.

But seriously, theoretically yes. And you’ll know pretty quick if it’s holding as you loosen the plug.

To play devil’s advocate, what will you be sucking into the engine? Are there any soft hoses that you will collapse with the vacuum?

Just flip it over and change the drain plug. This is NC4x4.

Just hit the existing one with a 1/2" impact. That should get it to quit leaking

I would do the whole drain/pour back thing personally

I have changed 2" fittings in hydraulic tanks with a shop vac. You won't have an issue.

My wife has a car that is difficult to drain the oil from without making a mess. I tried the shop vac trick several times and it works perfect. I just wrap a rag around the hose so its not a "perfect" seal, stick it in the oil fill, turn the vac on, remove drain plug, turn the vac off while holding a shield to deflect the oil. It doesn't leak a drip as long as the vac's on.

I got the idea from this guy. His stuff pops up in my feed all the time.

I saw this on YouTube, it'll work.

If nothing else, be ready with that fat thumb of yours.
