Nice guy, Fast Work, Sloppy shop…read more I had some head work done here earlier this year for a Nissan SR20DE-T and after receiving my head back there was enough issues with it that I wouldn't recommend going back. I came to have my head resurfaced, cleaned & finally for installation of new valve seals with BC springs & retainers. Mike was friendly & upon inspection of my head he recommended new guides, so I brought him some the next week no problem as I did with the other parts to help streamline the process. However after I received my head back from the shop & inspected it at home I noticed a few problems with it & I'm disappointed. I'll start with the more minor issues and end with the bigger ones. 1st issue being paint over-spray, personally I don't want my head to be spray painted at all but that's my fault & I should have clarified. The paint work is done fine & it does look bright like aluminum but there was built up over-spray and residue on the head surface that had to be cleaned off with a plastic razor blade thoroughly. 2nd Issue is one of the valve keepers wasn't installed fully & a separate valve keeper had a piece of metal wire stuck in it (Like from a wire wheel). Annoying, but not that big of a deal to me as I have the tools to fix the two messed up keepers. 3rd issue, & the biggest issue of all is that the head kept dropping metal shavings out of it, as It was not cleaned properly after being resurfaced. At this point I had to have the head disassembled completely to clean it all out & be rebuilt.. If someone wasn't as mechanically inclined & somehow managed to install this head it would have ended in complete engine failure. Overall, staff seems fine. Fast work, maybe a little too fast as this shop needs better quality control.

At the time he came, I had not driven it in awhile and had some issues with squirrels. But I had it fixed and drove regularly since and confirmed with a local shop. I called wondering if I could have him come out to fix it (I thought labor was covered under warranty). He said it wasn't and started saying that he has never had issues in 10 years and he wouldn't come out because gas was too expensive. I am willing to pay someone (including him) to fix it, but opted not to go with him because he was speaking unkindly and accusing the other mechanic of being wrong. I am disappointed in the service and follow up. I would suggest going to a local shop instead of someone who travels.

I am not sure if it cost more than my regular mechanic, but I was glad that I didn't have to make an appointment and was just able to wait. The reason why I am only rating them 4 stars is because when they changed the cabin air filter, they moved everything that was neatly organized in my passenger seat to get to the glove box. They ended up just throwing everything everywhere in my van. If they had just told me to move everything, I would have. I just wanted an oil change, but they told me there were other things that my van needed, and I said yes to everything they suggested. I did not know they would need to get into my glove box. I wish they had just asked me to move my things instead of making a mess. Other than that, my van drives wonderfully.

They started off amazing, but over the last 8 months have been sliding down hill, and are basically at rock bottom. This last time, I checked their website and Google listings. They both said SMOG services are offered, and specifically said, no appointments, head over (which I have been told MANY times by this place). So I show up, park in line, and a (very nice and polite) employee tells me that the person who does SMOG is off Monday and so they can't help me. I asked why the website doesnt list times or they don't set appointments and was told "we do not do anything with the website," and as he wasn't going to do anything for me, and I was clearly upset and he didn't want to actually handle a customer service situation, he decided to say have a nice day and walk away while I was in mid sentence and going to ask for a manager. My advice, it is no longer a reliable place to take your car. Go anywhere else pretty much! I know if I can find another CarMaxx certified station quickly, I will NEVER use this place again.

I have been going to Jan and Deily for the past year and a half, for various company projects, as…read morewell as my side-projects for my house and cars. So it has been due time for me to write a review for him. Before I do, I have to say it is funny to read other reviews on Yelp, like the one about pressing car bushings (which truly not even specialized car shops would do). I have to go back to Jan for that, because I did not know he did such things. I had given up on replacing bushings on my car, after being turned down by so many local auto shops and mechanics. Now for that reviewer that rated them badly for a four week lead time... what sort of expectation was that? A poorly-run machine shop has downtime to let anyone cut in. By all means go to those shops instead or pay an arm and a leg, if that is the expectation... however, Optima Precision operates like all properly run, established machine shops do... schedule your work into their operation or work an expedite out with Jan and Deily... We are even lucky they are open to our side-projects. Bottom line, talk it out with them. They are very open to making things happen! Anyways, just to give a little background, I formerly worked as a design engineer for Zodiac Aerospace's oxygen system division, that made a lot of pneumatic components such as valves and manifolds. I can certainly attest that Jan and Optima Precision has the expertise and capabilities to machine top-notch quality parts. Whether you are dealing with extruded, cold-pressed, tempered aluminum, steel or etc., or softer brittle plastics like plexiglass or acrylic, up to something like 6 feet by 4 feet (double check with him), he and his crew can take care of that. I originally went to Optima Precision because Jan and Deily were the more responsive, local machine shop. They are very approachable and easy to communicate with (their English is solid). Most importantly, their pricing and lead times were very competitive, compared to the other shops in the area. Easiest way to describe them is that they are flexible and understanding like the old machinists but they operate with the newer CNC mills (even though they have Bridgeports off to the side). In other words, they are not like other new machinists that refuse small orders and cannot think other than what their CNC machine tells them they can or cannot do. What do I mean by an old machinist? Jan did not just go off my engineering drawings, but he verified my design intent to make sure my parts would fit and functioned well in my application. He was more concerned with what I wanted my part to turn out as, rather than what his machines could or could not do. To affirm other reviews, Jan and Deily are truly open to make small quantities (even one or two pieces like other reviews stated) and, of course, scaling to large production quantities. If you have worked with machine shops enough, you would understand that Optima Precision is a no brainer to have your parts, at least, quoted there each time. Long review, but hope that helps you all when considering!

I dropped the part off at another machine shop and had it back minutes later machined perfectly to specification.
