Got my 22re engine back, had a tick add soon as we put it in and started it. Sent it back with our warranty, very rude about us calling ahead to take it back. Once they were finished with it, they claimed for it to have an exhaust leak which it did not have before hand, and we're also very rude about that too. I can't say I'm ever returning due to the careless attitude and work ethic.

Midwestern is a top notch facility. Incredibly talented machinists, Warren Jaggers is always knowledgeable and helpful, and Jason, the owner is as honest as they come. Highly recommend this place. They've never let me down.

I spent over $8000 with them replacing my engine. I’ve been back in twice to have the rear main seal replaced and I now need a third one. I gave them every opportunity to try and fix this but they got me so good on this I think I’m just going to have it fixed myself. It seems like John says what he needs to and he definitely make sure that warranty is out of date. I really wish I would’ve checked the reviews prior to go in there. If there was a way to sue them and get my money back I definitely would. Not a place I would ever recommend

Midwestern did a fantastic job replacing the engine in my 2003 Windstar. The new engine looked completely different than the original engine, but it ran like a thoroughbred. The work was done on time, on estimate, with no goofs, and the staff couldn't have been more professional.

Sent a customer of mine there to have the head checked and Rebuilt. Think they charged him almost $700 to have a valve job done when I called up there I explained that there was a ticking and a knock in the motor and that something was bent and it needed to be repaired and they said they could fix it so my customer paid the money picked it up I installed it and it sounds exactly the same as it did when I sent it there so when I call and talk to them they tell me that they're just a machine shop I don't get it I don't get why my customers money in my time was just wasted. Do not use this company

I spoke to them before dropping off a crank shaft that spun a bearing. They assured me they could fix it. They sat on it for two weeks, then told me it would be another two weeks to fix it. I had to call several times just to get an answer whether they could fix it after it was taking longer than expected. Warren is rude and hung the phone up on me for asking questions about what the problem was. I gave them all the factory specs and went out of my way to make their job easier. I drove two hours one way twice and ended up taking it to another machine shop who mic’d, checked for balance right

Very pleasant company to deal with. Quality craftmanship done in a timely manner. The long block removal/install had no surprises and is now running like a new one (as it should). Thank You John and team. I highly recommended this place.

Some of the best work I've seen. I cannot recommend these guys enough, they did a fantastic job. Absolutely went above and beyond to take care of me. Would highly recommend for any and all engine work. Prices are also fair, and the work is done in a timely manner. Give them a call and they'd be happy to do what they can to help.

They have built several motors and have done tons of machine work for our business. Warren has always taken good care of us.
