Most garages that say they do engine work send the machining out to somebody else. Millet's does not. Blocks get bored here, cylinder heads get machined here, and then the same people put the engine back together. Forty years of it, two generations of Millets, ASE certified, and every job carries a twelve month warranty.
One half is ordinary auto repair, the brakes and the check engine light and the things that go wrong on a Tuesday. The other half is an actual automotive machine shop, which is specialty work people will drive an hour to reach because the shop that used to do it near them closed. Both halves run out of the same building on South Main, with the same people.
A rebuild done properly means the machine work and the assembly happen under one roof, by people who will answer for both. That is the whole argument for this shop. Nothing gets shipped across the state and back with nobody quite responsible for how it goes together.
Head work is precision work and it is the part most shops farm out. Customers have brought in everything from LS heads for a performance build to the head off a Saab 900, which tells you the range better than a list would. Bring the head or bring the car.
Blocks bored and cleaned up on site. If you are building something and you need the machining done to a number rather than close enough, this is the part of the business that is genuinely hard to find within an hour of Piqua now. Call and describe the job.
Old iron and built engines are regular work here, not a novelty. One customer brought in a 383 block for a 1970 Roadrunner. Another had LS heads machined and assembled and came back with the block. If you are putting something together, you can talk to someone who has done it before.
The everyday half. Oil and fluids, belts and hoses, heating and air conditioning, electrical faults, general maintenance and the things that turn up without warning. Cars and trucks, foreign and domestic, with the same twelve month warranty on the work.
Check engine lights and the faults that do not announce themselves. A customer review puts it about as well as it can be put, they figured out a problem another shop could not. Having a machine shop in the same building tends to sharpen the diagnosis on anything engine related.
Brakes, suspension, batteries, starters and alternators, and the scheduled maintenance that keeps the bigger repairs from arriving early. Ordinary work, done by people who are ASE certified and have been on this street for forty years.
Search for an engine machine shop anywhere in the Miami Valley and Millet's will not come up, because every listing that exists files them under generic auto repair. Eighty reviews averaging 4.6 stars, reviews that specifically describe block boring and head machining, and there is not one page on the internet that actually says this shop bores blocks. That is a lot of capability sitting invisible.
For anything machine shop related this is the right first move, because the answer genuinely depends on the part. Describe what you have and what you want done to it and you will get a straight answer about whether it is work they take.
A block for a street build and a head off a daily driver are different conversations. Engine, year, what has already been done to it and what you are aiming at. The more specific you are, the more useful the answer.
Machine work can come in on its own, you do not need to tow the whole vehicle for a head or a block. For repair work bring the car to 1004 S Main Street and leave time to talk it through rather than dropping keys and running.
Work carries a twelve month or twelve thousand mile warranty. Ask for the detail on your specific job when you book it in, so you know exactly what is covered before the work starts rather than after.
Millet's has been on South Main Street in Piqua since 1985. Cory and Art Millet run it, the mechanics are ASE certified, the BBB rates them A plus, and eighty reviews average 4.6 stars. None of that is the problem. The problem is that their Instagram bio, their BBB listing, their Birdeye profile and their Dun and Bradstreet record all link to milletsautomotive.com, and that domain does not resolve. Every single person who clicks through gets a browser error page. On top of that, Yellow Pages and Superpages both publish the shop's hours as one in the afternoon to six, which would send somebody here five hours after the doors actually opened, and nearly every listing they have is sitting unclaimed. Forty years of reputation is pointing at a dead link. This page is what it could point at instead.
These are the hours carried by the Google fed listings, and they are the ones most sources agree on. Worth knowing that the internet does not actually agree with itself here. A couple of directories say nine to six, and Yellow Pages and Superpages both say one in the afternoon to six, which would have you arriving five hours after the doors opened. If you are making a special trip, please ring (937) 773-8909 first.
The shop is at 1004 S Main Street in Piqua, down near Meteor Street. Machine work can be brought in on its own, a head or a block does not need the whole vehicle towed along with it. For anything you are not sure about, ring (937) 773-8909 and describe the job first.
Whether it is a check engine light on a daily driver or a block you want bored for a build, describe it and you will get a real answer. Calling (937) 773-8909 is still the fastest route, particularly for machine shop work where the answer depends on the part, and this form works too.
Machine shop work is quoted on the specific part and what needs doing to it, so there is no price list to post honestly. Say the engine, the year and what you are aiming at and you will get a real number rather than a range.
$49 one time setup, then $79/month, no contract. Hosting, lead capture, traffic tracking, and your own dashboard are all included.
