Engine repair service near Costa Mesa, CA

1 year ago my brother-in-law referred me to Midas Diamond Bar after I told him I felt the Toyota dealer I had been going for 3 years up-sold some unnecessary services to me. Since then this place has been my go-to shop for all my car maintenance and repair. The staff (Nitin) was really nice and very honest. Doesn't try to push some unnecessary services to you. They make sure that they take care of you nice and fairly and that you feel comfortable with them so you will come back. And I will def come back. -Jared Wu

These fellas here are extremely helpful and know their biz. Highly recommended. Matthew Marusak

OET had my problem diagnosed within two hours and had my car back to me within the same day. I was shocked when I was told that the problem was minor. My repair cost substantially less than I expected. I knew then, that I had finally found an honest mechanic.

Went here on a referral with a coupon to have AC service. Mechanic did a good job , didn't try to up charge me. Honesty and integrity very much appreciated don't find that with a lot of mechanics these days!

What I love about this place is that they are courteous and helpful. I called and spoke w/ Bill the manager told him my issue, brought my car in and because it was just a minor issue I was in and out in about 30 mins or less!!! I will definitely take my car back there!

Incredible. It’s too early to give Hi-Tec two thumbs up but if it runs as good as it looks I’m going to be happy. Aaron say’s the team should be done this week and he is going to call me.

The engine was out of my car and Aaron said the parts came in on Tuesday and they were going to start the rebuild. My car has been in the shop for seven working days now. More to Follow. Read the beginning of my story below. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> My 1997 Camry shot a rod through the block the other night. The car is in great shape otherwise, straight body no dents clean interior. So, I look at all the options and decide that having the engine rebuilt “COULD” be the best option. I called a few shops and looked into the best place to have the work done. Then I called Hi-Tech engine in Gardena. I spoke with Aaron and he seemed very confident that they could take care of me. I mean the guy knew everything about my engine and reassured me that Hi-Tech specialized in engine rebuilding. So, the next day I had my car towed in and Aaron gave me a tour of the shop. Well, this is not a simple repair shop. Hi-Tech is better described as an engine-rebuilding factory. They have a full-blown specialty machine shop that appears to be well staffed. They have a large inventory of replacement parts and I noted the presence multiple engines in various stages of rebuild. They have a special area for engine install, in short everything looked good. Aaron told me that the job should take between five and ten working days and would include a 1year/12,000 mile warranty. I decide to trust him and at th
