    The guys at Quality Cylinder Head Specialists are professional and had great communicators. I trusted their expertise and recommendations. The head came out great. Thank you DL

    Took my head to get done for head gasket job and they didn't even bother to take off intake gasket which was stuck on there, now I'm here trying to scrape it off. Lazy job.

    Quality Cylinder Head Specialists went above and beyond helping me bring my 2014 Toyota Tundra back to life. Head gasket blew at more than 240,000 miles and was being told I should get a new engine by multiple other shops... but thankfully Coby & team guided me in the right direction and I was able to get the gasket fixed and heads rebuilt like brand new! Tundra runs like a champ again and will be for a very long time thanks to this shop!

    Love, love, love this shop. I use this place all the time for all my cylinder head needs. Coban is very helpful and easy to work with. My parts are always ready on time and on budget. It's a good place to get your machining needs done.

    These guys are in a class of their own. I would not trust anyone else with cylinder head needs. Great customer service and world class impeccable "quality". Had them service a Toyota 2.4 head and loved the result. Workmanship was amazing now running like new. They were fast reliable and best of all sent me pictures of the progress. I can't say enough about the level of expertise and service I received. If you need work on a cylinder head they should be the only shop you call.

    Found these guys on Yelp. Took my cylinder head over for my 1970 International Scout 800 and they found out it was cracked. Chau the owner and Coban went out of their way to help me and make the experience a good one. These guys do quality work and take good care of their customers. Tell them Matt with the International Scout sent you.

    I had a really great experience at this shop and honestly can't recommend them enough. A few weeks…read moreago, my catalytic converter was stolen, and I had it replaced at another shop. After that repair, my check engine light suddenly came on--even though it wasn't on before. The first shop told me it was a problem with the mass air flow sensor and tried to charge me to fix it, which didn't feel right to me. So I decided to come here for a second opinion, and I'm really glad I did. The mechanic took the time to properly diagnose the issue and walked me through everything step by step. Within about an hour, he figured out that it wasn't the air flow sensor at all--it was just a blown fuse. That alone saved me a lot of money and potentially from being overcharged elsewhere. What really stood out was the honesty and communication. He explained clearly what went wrong, didn't try to upsell anything, and made sure I understood the situation. On top of that, he even aired up my tires for free, which was a nice touch. Fast, honest, and affordable service like this is hard to find. I'll definitely be coming back and recommending this shop to others.

I had a concern that maybe the price was so good because they were using tires that were patched or something but nothing could be further from the truth! They shared were they source their tires from and rest assured you're getting a great deal for sometimes practically new tires. These guys and girls are the real deal. They have earned a life time customer and my trust to send my friends and family in the future!

I used to have a mechanic for YEARS…read moreat another shop, but unfortunately they got bought out by new owners and hiked up prices so much. Fast forward, I had gotten work done at this shop for my first time (I forget now what it was for).. & everything was quick and easy.

Unfortunately, when I arrived, Carson was heading out for a break, so I had the displeasure of working with Langston at the front desk. Langston told me that Carson had given me the incorrect quote over the phone, which was fine; I just said I would go elsewhere for cheaper. When I told him this, he responded that his prices are the way they are because he uses quality parts. I asked him if the part would be aftermarket, and he said "it's Japanese." That didn't answer my question, so I asked him if the brand was Denso, and he said "yes, that's Japanese, right?" Aside from my interaction with him, I saw Langston being rude and giving attitude to my guy Carson after he came back from his break for no reason at all. I ended up going elsewhere to get the job done with the same Denso part for $100 less (close to the original quote that Carson gave me). Moral of the story is that I don't trust Langston, and I certainly don't like how he was treating Carson. Maybe he was having a bad day, but his attitude today was enough to make me question coming back here in the future (which is unfortunate because everyone else here is really kind and patient). Special shout-out to Skip for checking my car and sharing his knowledge with me.

    Jesse is the reason my cat is alive…read more Last weekend, during the Garden Grove toxic chemical evacuation, my tuxedo cat decided that the undercarriage of my cousin's Tesla Model Y was a great hiding spot. It was not. He was wedged in there for 12 hours with no food, no water, and zero litter box access. He was absolutely losing it. I ran through every option. Fire department? Busy with the actual chemical explosion rattling all of OC, fair. Animal control? Ghosted me. My cousin, currently out of the country, tried Tesla Roadside Assistance through the app. Tesla's answer: their technicians are not trained to rescue animals. Noted, but deeply unhelpful in the moment. Two other mechanics passed too. Jesse was my third Yelp attempt and my last real option. He showed up within two hours, no fuss, and got straight to work. He tried everything - the frunk, underneath, removing the right wheel - methodically working different angles for an hour and a half because my cat had chosen the most inconvenient possible position to be chonky in. Jesse stayed patient the entire time and got him out safely. My cat is home. He is fine. He is completely unbothered, as cats are. Jesse showed up when nobody else could. That is not something I will forget. Oh, and his prices are insanely reasonable. If you need a mechanic who will actually show up and problem-solve, Jesse is your guy.

    I paid Jesse $120 toward motorcycle service, and apparently accepting payment was the only part of…read morethe job he was interested in completing. I had ordered a part and was waiting for it to arrive, so about a month passed. During that entire time, Jesse never contacted me to ask whether the part had arrived or to follow up on the work I had already paid him to do. I eventually had to reach out to him myself. Over the following three weeks, I sent multiple text messages and called several times, all of which were ignored. After getting nowhere, I called from a different number--and suddenly Jesse answered. His excuse was that he had been "busy." I asked him to send me my money back and he hung up and blocked my number. In total, nearly two months passed after he took my money with no communication, no follow-up, and no attempt to complete the service. Being busy may explain a delayed response. It does not explain ignoring a paying customer for over two months while continuing to keep their money. That is not poor time management; it is poor business practice. There was an $80 diagnostic fee, so technically I am only out $40. Financially, it is not a huge loss. Professionally, however, it says everything I need to know about this business. A reputable business does not take payment, fail to complete the agreed-upon service, ignore every attempt at communication, and then offer excuses only after being reached from a number it does not recognize. The motorcycle needed a diagnosis, but the bigger problem turned out to be the business itself: unreliable, unresponsive, and completely lacking in accountability. I would not trust Jesse with my motorcycle again, and I certainly would not recommend paying him anything upfront.

    I got a few quotes before deciding to bring my 2014 Prius Plug-in here, and I'm really glad I did…read more They weren't the cheapest and they weren't the most expensive, but I felt like they charged what they needed to in order to get the job done I had no idea they even worked on hybrids because I never saw that mentioned anywhere, and I think more people should know. They took the time to explain the repair, confirmed the diagnostic code, and even pointed out a few things I should do to help my Prius last longer. They noticed my hybrid battery cooling fan was missing after I told them I just had it "replaced" at another shop. That's the kind of information you don't usually get from a repair shop. They ended up not needing to drop the subframe, so they adjusted the labor instead of charging me for work they didn't have to do. It still took the amount of time they said it was going to take, but still discounted me a little bit which I thought was cool. I also had them do an oil change while it was there, and even that was less expensive than what I normally pay at places like Jiffy Lube or Valvoline. If you own a Prius or any hybrid, I'd definitely recommend checking them out. More than anything, I left feeling like they genuinely know these cars and took the time to educate me, not just fix it. I'll definitely be bringing my Prius back if I ever need anything else.

If you want to read more reviews on Nick's service however, you can read the reviews posted there as well but call the number listed here to reach Nick* Nick totally came to my rescue on Sunday (2-10-2013). Within 45 minutes of contacting him he showed up to where my car was in Anaheim and did all 4 of my brakes for literally an eighth (yes, really an eighth) of what other places would charge. My car was completely disabled and the brakes were grinding metal to metal and in less than 1 hour I was up and running again! I figured I'd have to pay more for the convenience of having him come to me and for the speedy service but it was the opposite. What a pleasant surprise! I will never use another mechanic again.

    Too bad I can't give Nick more stars than five... that's the maximum!…read more Nick unbelievably helped me with my problem without charging me a dime. He was super patient with me (I am not automobile inclined) as we tried to diagnose my issue over the phone so that he could give me an accurate quote. I truly believe that any mechanic I have ever met, including my own brother, would have found a way to shake some coin off of me before helping me solve a problem, but Nick was up front about the prices (more than reasonable) and knowledgeable, giving me some troubleshooting ideas and a few options to best accomodate me. I won't bore you with the details (I have a small leak in my hydraulics), but I appreciate that he didn't insist that I make repairs, like a doctor or a dad would do. And he wanted to know how my troubleshooting worked out, calling him back either way, like a date dropping you off at your house and waiting for you to turn on your porch light to make sure you're safe. Anyway, this might sound weird, but I am actually looking forward to my next automobile issue because I want to give Nick my business. I trust him completely, and you don't hear many people say that nowadays. :) Thanks, Nick!!

I found Francis through an online search because of the many positive reviews, and during our first interaction he was friendly, professional, and seemed very knowledgeable. He ordered the part directly from Acura and quoted me a fair price. My car was ready the following day, but when I arrived to pick it up, Francis informed me that my vehicle had been involved in an accident while in his care. He explained that another driver had been speeding through the parking lot and crashed into him. He gave me the other driver's information, and I contacted him immediately. The other driver gave a very different version of events. He stated that he was backing out of a parking space and did not see Francis. He also told me that Francis provided his driver's license information but refused to share insurance information. Now, more than a month later, I still have a damaged vehicle and have not received insurance information from Francis despite multiple phone calls, text messages, and outreach from Mercury Insurance. I trusted this shop to take care of my car, not return it to me in worse condition and leave me responsible for a $500 deductible. What has been most disappointing is the lack of accountability and urgency. Francis acted as though this situation was not a major concern and repeatedly assured me that the other driver would "take care of it," which has not happened. According to the other driver, Francis even asked him to change the story about what happened. I chose this business because of its strong reviews and the image Francis presents, but my experience has been extremely stressful and disappointing. I believe customers deserve honesty, transparency, and responsibility when their vehicle is in someone else's care.
