I am changing the timing belt on a 92 Plymouth Voyager, 3.0 liter Mitsubishi engine.
I have been unable to break loose the 22mm bolt attaching the damper to the crankshaft. Have tried breaker bar and 4 lb. hammer, breaker bar and 2 ton hydraulic jack, air impact wrench (230 ft. lbs. torque only), staring at it while scratching.
I am open to suggestions.
Have tried turning both directions and KR Oil soak as well.

If you can secure the engine from rotating, try putting a cheater pipe on the breaker bar for extra leverage. I use an old handle from a retired floor jack. Excersize caution though.

BE ADVISED: Make certain the socket is fully engaged with the bolt to prevent slipping/stripping the crank bolt.

I'm not being sarcastic, but if that doesn't work and the van still runs, I'd trade quickly.

Have used a cheater bar, no joy. The timing belt is broken, so little van runs no more.
I am searching the neighborhood for a beefier impact wrench. If that doesn't work, I'll flip a coin between a rebuild and a part out, I reckon.
It's been a good van, 30 mpg on the open road, plenty of pep, only 160K miles.

OK, I'll give a suggestion. You can attach a socket and a breaker bar to the nut and kick the starter briefly.

Am considering that. Have seen this done before and witnessed much injury and destruction result. Many precautions to take.

True. Those crankshaft bolt can be really difficult. It's not markred a left hand thread, is it?

Use a floor jack on the business end of the cheater bar and tell everyone to stand back.

Remember to use a 6 point socket, preferably impact.
