I decided to give Engine Supply a try after my previous engine developed a major oil consumption…read moreafter a rebuild. I have yet to disassemble and determine the cause on that engine. I needed some cylinder head refresh work done on a replacement engine and took my head here. It's for a bmw s54 engine. I understand Engine supply does a lot of domestic work but will also do European and Japanese engines. After speaking with one of the guys, I found out that it's a family owned and operated company. The guys are definitely knowledgeable. The cylinder was picked up and was in great clean condition as expected by a good machine shop. What impressed me was they took me to the back to show my cylinder head during assembly when I dropped off my valve seals. The shop is well organized and clean. When I picked up the cylinder head, the Machinist who worked on my cylinder head also mentioned that the valves were returned in the exact order it was removed, which makes putting the shims I removed back it the same order easier to adjust the valve clearance on assembly. The cylinder head was assembled back into the used block. And is now running in the car without any oil consumption. It has done multiple track days without issue. I'm very happy with their work and can vouch that you are getting top notch quality work. Thank you Engine Supply Team! -Clarence

Precision Tooling

I recently brought a small job to Precision Tooling (bolt broken off inside one end of a large…read moreshaft). I left it to have the broken piece removed. The original bolt was sealed with Loktite by the manufacturer, so it wasn't easy to remove the broken piece (and the end of the bolt was deep inside the shaft, not accessible). When it was ready, I came to pick it up -- I asked how much I owed... answer: "no charge." (!!!) I said, "Really? Come on, you have to charge something." -- "No," he said, "it only took a few minutes." This is the kind of business philosophy everyone should have... charge a fair price (or nothing if it's quick and easy)... success will come, your reputation will grow, you generate a loyal customer base, and make your profit on the large jobs that justify higher fees. I hope everyone who needs a good machine shop will support Precision Tooling in Fountain Valley! Good work, by Quality people.

My request went through the Yelp Project page first and Jose was very fast with his response. He told me I could come in on a Friday morning as a walk in. Gino who took care of my intake was very friendly and made me feel welcome. They also had a comfy waiting area stocked with complimentary coffee and snacks, but I didn't need to wait long because I was out of there within an hour, oil changed and tires rotated. Their prices are fair and they accept both credit card and cash/Zelle (if you want to avoid the 3% credit card surcharge). During the oil change they also noted some things that will need repair, but weren't pushy with their recommendations. For that I am very appreciative, and will most definitely come back for their continued services.

Their prices are the most fair in the area, but the quality, the skill, the knowledge that were provided was TOP NOTCH. Very honest and knows alot about cars.

If you need a pre-purchase inspection or any auto repair, whether it be european, american, japanese made, etc, and EVs, take your car here and don't think twice. We reached out to Arnold for a pre-purchase inspection. While six other places quoted us $250-$350 for a "comprehensive" inspection, we paid Arnold $100, which was a STEAL for what he did, even more than what the others promised. He spent at least two hours thoroughly checking the vehicle, test driving it and walking us through every detail so we truly understood its condition. We were looking at buying an Audi Q4 e-tron that had a damage report. A reputable dealership told us it was "minor" and offered to take it to the mechanic for our peace of mind. After browsing Yelp and reading the amazing reviews, we decided to come here instead and I'm so glad we did. I had already done my due diligence and familiarized myself with the vehicle and potential issues. I asked Arnold very specific, technical questions that I already knew the answers to. He answered every single one with clarity and confidence and everything I was expecting to hear. My husband stayed the entire time, and Arnold patiently explained everything while inspecting the car. You can tell he was that kid that made the auto shop his playground growing up. He's passionate, meticulous, and GENUINELY cares. What impressed me most is that Arnold will never pressure you. He won't tell you "don't buy it," but he will clearly explain what could go wrong and what it might cost to fix. When I pressed him for his honest opinion, he said he personally wouldn't buy it at the listed price but if we negotiated it lower, then it might be worth considering. That level of honesty is RARE. They are your small local auto shop but I would choose them over any flashy, grandiose service center any day. Their integrity and transparency make them stand out. Thank you so much, Arnold and your dad, for the amazing service. We ended up just buying a Tesla!

Fast forward to this instance where I have a batch of rotors that I needed to be turned down 1mm each side. Call him, describe what I'm needing and ask if he has a rough estimate on price. He asks me to text pictures, I jot down his number and then send him pictures shortly after. Gave him an hr or so and called him back to see if he received the pictures. Doesnt reallt acknowledge it and is pushy to have me bring them in and that he can do it. I'm about 25ish mins away, but he insists that he'll be late at the shop and that it's no problem. I bring in 1 rotor to see if he can still give me an estimate and he suggests he can help me bring in the rest of the rotors, about 10 in total. As we're bringing them in, I ask him again how much he's thinking it's going to be and he mentions $50 each. At this point, it's beyond the threshold in which the supplier was going to reimburse me for so I ask if I can just machine 2 rotors for now and figure out what can be done with the supplier. The next week rolls around and days go where I dont hear anything. I text him and no response for a day or 2. I call later the following week and he gives me a response like the rotors have been done and that he's been waiting on me. I ask him texting is the best method of communication since he originally asked me to text and he said text is good. I ask him if he's been receiving my texts in which he responds with affirmation. I go to pick up the rotors and come to find out that he only did a single rotor in which I ask when the other side would be done and he says in about 1-2 business days. I say that's fine and then mention that I'll leave that single rotor behind and grab the rest. He then mentions that if I in doing just 2 rotors, that the price would be $100 each. At this point, I'm no longer feeling like this is about money and get the impression that he's just a shady crook now trying to take advantage of people. I'm a little shocked at the pricing at this point and ended up just taking all the rotors back and paid him his $100 to machine a single rotor. Ended up having another shop do the for $20 each
