1. Richards Complete Machine Shop
Website: https://richardscylinderrepair.com/
Address: 6403 W Thompson Rd, Indianapolis, IN 46221
Contact: (317) 856-9163
Hours: Monday – Friday: 8 AM – 5 PM | Saturday: 8 AM – 12 PM
Richards Complete Machine Shop excels in high-performance competition valve jobs and custom porting to maximize airflow. They handle expert cast iron and aluminum welding for severely cracked heads.
I recently dropped off a badly warped cylinder head here. Their machinist handled the complete bottom-end block process smoothly.
They perform rigorous multi-step pressure and vacuum testing on every piece. This guarantees tight valve seals before anything leaves the bench.
The main catch is that they offer zero removal or installation services. You have to pull the engine yourself and deliver the bare parts. They strictly focus on internal long block components rather than general auto repair.

Broke down near Indy with our 21 year old motorhome. Was towed to a dealership who found the problem to be a blown sparkplug. This was something new to me. I was told they would have to swap out the engine at a cost of around $10000! A friend suggested calling a machine shop. I called Richards. Within 2 hours of dropping it off there, they had it fixed! They were friendly, confident and did a great job. Cost – around $ 421! These guys know what they are doing. Thanks a million guys.

2. Grewal’s Automotive
Website: https://www.grewalsautomotive.com/
Address: 5210 Commerce Cir Suite C, Indianapolis, IN 46237
Contact: (317) 886-7501
Hours: Monday – Friday: 8:30 AM – 6 PM
Grewal’s Automotive brings over 40 years of industry experience to every engine block they touch. Their factory-trained technicians provide dealership-level expertise specifically for Ram, Chrysler, Dodge, and Jeep vehicles.
They run advanced diagnostics to pinpoint exact mechanical failures while guaranteeing the use of original equipment manufacturer (OEM) parts.
These master mechanics handle everything from minor gasket fixes to complete engine and transmission rebuilds. They provide completely transparent, itemized estimates before starting any wrenching on your vehicle.
However, their standard one-year warranty falls slightly short compared to the three-year guarantees offered by large national networks.
Also, the shop stays closed on Saturdays and Sundays, and it doesn’t help that they operate from a single south-side location, which makes them less convenient for drivers living on the far north side.

3. Thompsons Auto & Diesel Repair LLC
Website: https://thompsonsautoanddieselrepair.com/
Address: 3709 Madison Ave, Indianapolis, IN 46227
Contact: (317) 601-2483
Hours: Monday – Friday: 8 AM – 5 PM
Thompsons Auto & Diesel Repair LLC brings over a century of combined expertise to complex automotive and diesel systems. This veteran-owned shop delivers an honest approach to heavy-duty mechanical work. They focus heavily on complex diesel engines and recreational vehicle (RV) repairs requiring specialized bays.
I spoke with a local fleet manager who praised their quick same-day appointments. The crew uses high-end diagnostic tools for complicated transmission and engine overhauls.
Unfortunately, you won’t find weekend service here because they stay closed on Saturdays and Sundays. The small team size also means they process fewer massive rebuilds at once compared to large factory setups.
Customer Reviews
My friend put me onto James Thompson about a year and a half ago. I’ve had a LOT of mechanics over the years… But James & family have took care of everything I’ve brought to him… Treated me right on pricing as well as efficiency in getting my trucks/cars /equipment back to whilst keeping me up to date on diagnosis on anything he has of mine over there. Good people,Good prices,Good work.

4. Young & Sons, Inc.
Website: http://www.indianadiesel.com/
Address: 412 W McCarty St, Indianapolis, IN 46225
Contact: (317) 263-0960
Hours: Monday – Friday: 8 AM – 5 PM
Young & Sons, Inc. removes the middleman so you buy directly from the diesel mechanics building your engine. This family-owned facility brings over 75 years of specialized experience to the city. They run a full-service in-house machine shop to heat-treat and resurface blocks.
The team ships rebuilt engines and parts to customers nationally and internationally. You know exactly who takes responsibility for your heavy machinery.
On the downside, they exclusively dedicate their facility to diesel technology. You’ll have to go elsewhere if you manage a fleet containing gasoline engines.
Moreover, complete custom builds from a core sometimes require long wait times. This causes frustrating delays if your equipment breaks down mid-project.
5. ASG Automotive
Website: https://asgindy.com/
Address: 5841 Thunderbird Rd Ste.3, Indianapolis, IN 46236
Contact: (317) 826-2906
Hours: Monday – Friday: 8 AM – 6 PM
ASG Automotive runs a dedicated engine rebuilding program that breathes new life into old blocks. They address everything from piston rings to crankshafts to exceed original performance. The shop provides an industry-leading four-year or 48,000-mile warranty on their repairs.
They even offer around-the-clock towing services to get your broken vehicle off the road safely. The team loves disassembling and reconditioning classic cars until they look better than new.
That said, they maintain strict age limits on certain imported vehicles. Their Asian auto repair division focuses primarily on cars under twenty years old.
Also, the garage stays closed on the weekends. This limits your options if you need immediate weekend diagnostic help.
Customer Reviews
ASG’s diagnosis of my car’s engine issue was thorough and clearly explained. Their front-desk staff understand the technical details of cars, so you feel that you’re not getting upsold by a salesperson reading off a sheet. The work itself was performed quickly and at a reasonable price. They were responsive via phone at all points of the process.

Had a great experience with ASG. Needed major engine work and their quote was thousands below the dealer and others. Many months later I’m very happy with the performance of my car and I really appreciated how easy they were to work with. No pressure/sales tactics, they just really wanted to help.
