Zinola’s Machine Shop

These guys need to be put in prison! They rebuilt my Subaru Motor and they screwed it up so bad that it needs to be rebuilt again. I got the motor rebuilt in October of last year and it has been in the shop since December (yes you heard right, over 6.5 months)! The bearings were toast and the motor didn’t have barely any oil pressure, the cams had huge scratches in them from probably metal shavings in the oil, they JB welded my timing covers on, and the list goes on! So now my mechanic has to eat the bill and rebuild my Motor for free because these D-​bags scammed use both! I hope karma catches you and your family in the worst way JEFF! kick rocks you POS! I am going to call the better business Bureau on you and I will bad mouth your business all over social media and make sure that where ever you open a business people know that the work you do is crap!

Great shop and grate attention to detail. They bared with me as I had parts imported to build my motor. Would go back anytime!

Great and affordable work on a piece for my motorcycle

If I could give zero stars I would. Jeff does not stand by his word or work. Had some issues with my head job and had a third party machine shop evaluate and fix his work since the auto shop (a well respected Audi tuning shop) already called out Jeff’s sloppy work. Jeff returned our heads with nicks and uneven valve guides along with an uneven head resurface which seemed like it was done on a belt sander. Overall very poor head job.
Before starting the job I made sure he had worked on Audi’s due to the specs needed. He assured me it was no problem and he has worked on Audi’s before. I should have trusted my gut and walked away, but I did not and now I will be in court with Jeff and his shop.
Please use extreme caution when dealing with this shop. If your heads are spec’d down to the millimeter use someone else.
I am not an expert and I would recommend getting second opinions when dealing with this shop.

Been working with Zinola’s (Jeff and Jake) for about 6 months and have gotten the kind of service and value that you hope to find with every project. They are smart, reliable, thoughtful and really nice guys, take it here and you will get great value!

I dropped off a pile of parts and these guys turned that pile into a long block, and along the way saved my tail by catching some stuff I would have missed. Their customer service (months after my picking up the motor) was above and beyond what I could have hoped for, and you just don’t see such support in any industry as they provided.
If you don’t choose this shop for your auto machine work, you and your wallet will just be going in circles like a one-​legged duck.

Jeff is an expert in his craft and does great work. My cylinder heads always come out great and I’m always very happy with his work. He’s a very nice guy and always helpful to talk to about projects too.

I’ve been going to them for years and will continue to go to them for years to come. Not only do they go above and beyond but they give you an update status on what you’re getting done. I’ve had numerous blocks, heads, flywheels, high speed balancing and more done by them perfectly. Cheap, fast, local and extremely friendly. Performance to simple maintenance machine work I would recommend them to anyone. A++ service!

I’ve been working with Jeff for a little over a year now on several occasions and he always delivered a premium service. Honest, fair, reasonable. These are the terms I would use to describe my impression in the best possible way.
His work has always been flawless and I will continue using his services in the future for sure. Jeff is very experienced and has a ton of knowledge, you can immediately tell. He gained my trust pretty much with the first job that I had for him.
The turnaround is quick (usually 24 hours or less), his prices are very fair and he does great work. Nothing else I can ask for!

Whenever I need a head freshened up, from resurface to a valve job, Blocks that need bore and Hone, ZInola is the place to go. With reasonable rates and fast turnaround time, I cant complain. I havent had any issues with all the work he performs on my stuff. Its a bit far from where I live but its worth the drive. Great job Zinola.

Smart Fast and Reliable Machine Shop!
I have been selling rebuild engines for over 22 years and by far, Jeff has come thru for my shop every time. I have sent cylinder heads, short blocks and long block engines to Zinola with no problems… ever. Anytime I need a technical expert to help me with a project, Jeff has always been more than happy to help out. Just a good guy who has always been fair to me.
Thanks Jeff and family!

update:
the last item he serviced for me (the 2^nd head) turned out also have bad valves. He either took off too much material when he did the 3 angle valve job, or they were just too old to hold up to such a treatment. In both cases, he did not use his better judgement, and caused me more time and money to fix his mistakes.

Jeff is the man! Finished a valve job on my race motor in one day, priced right, and done perfectly. Very friendly guy, and does things right.

There is no better machinist then Jeff. Definately a talented good guy ! His work is clean, professional, and resonable!@
