RMS Machine Shop in
San Antonio (TX)

This place gets the job done ! Shout out to the team at RMS. They got me taken card of. Turn around time was incredible. They did my block,head, and crankshaft. They showed a level of care I was not expecting. They did not have to go above and beyond but they did. These guys actually care. Turn around time, quality, and great prices saved my project. Found a place I can trust. These are my guys now.

I came in just to get my air mass flow sensor cleaned and I thought I was just checking something off my to-do list and I would be in and out… after I left the shop my car broke down on the middle of the road and when someone came to help me the brakes locked up and I almost crashed… my car has never given me any troubles before I came here. Furthermore, I was told it would take about 20 minutes and I was there for over an hour and I had to miss work…. I wasn’t told anything about the price or payment (I assumed just a cleaning wouldn’t cost too much) but the price ended up being $150 and then they told me they only accepted cash so I had to go to the bank with one of their employees in my car to watch me. He was very nice though but the shop as a whole was very sketchy and unprofessional and now I don’t have a car.

Took my Toyota Supra cylinder head to RMS MACHINE SHOP and they completed it in two days when other shops wanted 3-4 weeks. Keep up the great work fellas!!!!

Ric and the team at RMS built me this 4.3 engine for my Blazer and it came out great. Thank and keep up with the killer work.

BEWARE! Read my experience. Warning: Avoid RMS Machine Shop 1830 Alametos, San Antonio I brought my car to RMS Machine Shop for engine repairs head gaskets. Ricardo Luna, the owner, quoted me \$600 for a water pump and timing belt kit, which I paid via Zelle while bedridden. He said the job would be done the next day, but after receiving my payment, he asked for another \$1,000, claiming the total cost was \$3,000 and needed half up front. I agreed but later tried to send the money, only for Zelle to block the payment with a scam warning. After looking up reviews, I saw numerous complaints about him taking money upfront and not completing the work. I decided to cancel and just pick up my car, but Ricardo claimed he hadn’t installed the water pump and kept the \$600. He also charged me for unapproved head work, changing his story multiple times. When I went to pick up the car, he demanded \$1,600 for release, refused to give an itemized receipt, and insisted on cash at the bank. I called the police, but he still wouldn’t release the car without payment. Next Steps: Got it!

Heys guys I’m Marco and I recently just had my cylinder heads both resurfaced as well as my Engine block and also had it bored out on each cylinder and had 2 sleeves replaced. I drove all the way from Laredo and man I’m glad I did. Everything came out phenomenal and I’d recommend this to anyone looking to also have anything of theirs resurfaced or worked on! Great customer service and worth the money! The pictures speak for themselves….

I brought in my 2006 Ram 5.9 Cummins to RMS Machine Shop and the didn’t disappoint. I was having terrible blow by on my engine and they bored it .020 over and put brand new pistons, rings, bearings and gaskets. My truck is ready for another 600,000 miles!!!! ??

Built me a 383 Stroker motor and man let me tell you it came out bad ass!!!! These guys are skilled and I can trust them 100%

Ricardo and the guys at RMS Machine Shop did a great job on my Chevy 383 Stroker engine. Got more work coming for these guys!!

Took my 2010 F350 6.4 Diesel truck to get engine overhaul, let me tell you these are some bad dudes, showed me the engine before and after. My truck came out sweet. It’s ready for another half a million miles. Ric and his pops are some good people. They got my business for the rest of my life $$$

Me being a girl not wanting to get taken advantage I went to 5 repair shops to get quotes and advice about my fuel leak. Land Rover dealer quoted me $7500 to repair and other shops quoted me for items that didn't even need fixing. RMS fixed the issue for under $2500. Honest and very transparent in explaining what actually was wrong with my car. Highly recommend!!! Ric was great and communicated everything during the process and even showed me the issue. Don't go anywhere else! Even for your high end car makes these guys can do it all and are quick!!!

RMS has superior customer service! The best of any business I've encountered in a very long time! My 2020 Mercedes SUV needed an engine replacement and they were able to service it quickly, efficiently and at a much lower price than other competitors charged to change it. Their waiting room was extremely comfortable and I appreciated the Christian music they had playing. I will definitely be using this business for any future mechanic needs and let my friends and family members about it.

To everyone’s different opinion on this business, My experience with RMS was incredible! I got stranded in San Antonio because I’m from the valley, my car overheated on the road and I called all around and nobody could get to my car until 2 weeks, so I called RMS and they got me back on the road in a couple days. I would highly recommend this establishment!

I brought my Honda Pilot to RMS machine shop for a engine overhaul and let me tell you guys this shop is A1 they told me 2-3 weeks and they knocked it out in 1 week. Now I am back to work with my car thanks to Ric the owner and the team at RMS!!!

Unorganized, communication is horrible. Dropped off a block with specific instructions. Gave a week time frame. Almost 2 weeks after the time it still wasn’t done and blamed me for not supplying parts when all they were asked to do was bore and align hone to my specs I gave. Once block was dropped off communication stopped, they ignored my calls and stopped replying. As well as price changed after they had the block. Was originally quoted $750 to do bore, align hone, wash & cam bearing m, to than $750 only covering the bore, wash & align hone. They also were very pushy for me to pay in advance which I’m very glad I didn’t. Drove up to see what was going on and they weren’t there. Employee gave me my block and parts after waiting an hour because they were lost. I paid for the work they did do and left. I wish I read their reviews before hand because this is apparently a normal thing for them. I will continue taking my blocks to Houston. Here’s a screenshot showing their previous suit of over 100k because of deceptive trade. “Shady business”

The absolute worst machine shop I’ve ever had the displeasure of experiencing. Ricardo Luna is the most unprofessional person I’ve ever met. Never at the shop. And when he is confronted with issues he always has an excuse. left him my engine block and heads and crank and $4000 later they gave everything back to me and the pistons did not even fit in the block. Crankshaft scuffed. Lost the main caps to my block. And gasket material still on the block. I take it to another machine shop and they measured it and said the work was not even done right. I confronted Ricardo about my issues and he said he did the work right and even showed me the equipment he used which was most definitely some outdated equipment from the 90s. If you care about your stuff don’t let anyone here touch it.

SAVE YOURSELF MONEY AND GO SOMEWHERE ELSE. They had my car for over a YEAR. Always gave me an excuse and asked for more money. Gave them $2500 before taking it to another shop. Turns out the “new” engine block they gave me was cracked and oxidized. So those $2500 were for nothing. They just spray paint the block and tell you it’s ready. Unprofessional and never pick up or return calls. Learn from my mistake and stay away from this place

I wanted to have a fresh rebuild for my 94’ Bronco restoration. Rick is a straight up guy! He quoted me 5 day turnaround and he kept his word. Price was really good (according to people that I asked on the FB Bronco restoration group). My bronco is now a daily driver and everything works good with the engine. You may see my Bronco around between Leon Valley and Helotes. I will be taking him another 5.0L that o want to have rebuild.

This place sucks! Beware don’t pay for anything up front! Paid this guy to rebuild my 98 chevy engine and he had my truck for about 6 months! Then when it was time to pick it up he was trying to tell me it won’t start it needs a starter. All it was is the truck was completely out of gas!Truck had a full tank of gas when it was dropped off! Make sure to take a picture of mileage before and after! They had put over 200 miles on my truck! I know they need to drive to test stuff but 200 miles? And then not even offer to put gas back in it. A few months later had to take truck back to a different shop but it was knocking and leaking oil among other problems. The engine was never rebuilt they just took it out painted it and put it back in.

Great service at first, but terrible performance, im really upset at the owner going to take legal action ( no lo recomiendo )$ 5600. engine rebuild ended up with low oil pressure and oil leak

My 350 sbc from an 85 Monte Carlo SS went into RMS for a gasket reseal and freeze plug replacement with repaint. It came back looking as good as it did when I had it rebuilt and honestly even better. Rick and his guys were able to identify why my “Old Gen 1,” wouldn’t stop leaking oil. Guys and gals, stay away from some of that pretty chrome aftermarket stuff. It’s not worth it! Just stay or go back OEM! It happens to a lot of us and we don’t even realize it. Thanks Again Rick and you have my loyalty!

Great workmanship, fast service, I showed up with my cylinder block and head after work and left with them both resurfaced ready to instal before dinner, thank y’all!

I share this experience as a warning for others NOT to do business with RMS machine shop. They take your hard earned money and make you believe their using new parts. When all along old rusty parts were installed. These people need to be put out of business!!!! They use new clients money to complete previous work. Rick Jr. deliberately doesn't return your call to check on the status of your vehicle. They destroy your property. SAPD has been called numerous times for the bad business conducted by this company. Even tow truck drivers are familiar with this place. I REPEAT DO NOT TAKE YOUR CLASSIC CAR, HOT ROD THERE. You will be ripped off. I firmly believe in Karma, what goes around comes around. Your company is not worth a one star review but I had to put one.

Worst machine shop ever, will not recommend this place to anyone in San Antonio. They took weeks just to put water and “clean” two heads, took them there because they had all nice pictures and reviews from before, but they disappointed me. They do not deserve to have 5 stars review, my girl is helping me clean the heads again with a tooth brush and degreaser and she’s doing it way better, she has no experience at all. And worst is that they charged $600 for that junk work. They haven’t even send me a receipt, guess they just wanted to get their Christmas presents money out of some customers. Oh well… the manager doesn’t answer texts, and have to call them 10 times so they can return the call and hour later IFFFF they do.

After a recent service visit to the BMW dealership, where I felt taken advantage of, I wanted to try somewhere different. I researched local service centers and found that RMS had overwhelming positive reviews. I had a good feeling from the start and am glad that I chose take my vehicle to them. The service, knowledge, and professionalism was above reproach. The environment and staff were friendly and family like, which I appreciate. I plan on continuing to take my vehicle here, as I know that it will always be in good hands.

PLEASE READ I'm going to keep it short, this place is an actual rip off. The service is terrible and so is the work. Ric kept on charging me for mistakes on his end. Absolute joke of a shop, never intend on going back. Better shops out there that actually work on your car. All the good review on this shop come from people he know, I've never seen that much BS in my life. Read the one star reviews as they are from actual customers.

Amazing experience! If my family or myself have any car problems this is our place !!! They’re fast, reasonably priced and they will take care of you !!! I highly recommend them . When I had recked my car , I went to other shops to get quoted and I was lied to about what needed to be repaired. RMS was honest and didn’t try to trick me into spending more money . They are the best .
