Precision Diesel - Winchester, Ontario

This shop sure knows what they are doing when it comes to anything diesel. I have been using Precision Diesel for lots of years now. Going on 9 years to be exact. I finally thought it was time to write a nice review that they respectively deserve. Way overdue. They have kept my 2014 LML Duramax running very healthy and fun to drive since I bought it. The very first visit was to install a FASS lift pump to keep the Bosch CP4 feed with lots of fuel so I could sleep better lol. Also we put a S&B intake on the truck to help it breathe cold air. My latest problem that occurred late summer was that I was getting a pressurized coolant bottle 😢. It was a classic case of a bad head gasket. This occurred regardless of meticulous maintenance over the years as well. So Richard and Matt’s mechanics in the shop knew exactly what to do. They gave me a few options for the build also. Using factory parts or to OEM + it and bulletproof it for many more years to come. I told them to bulletproof it 🤘. The heads got sent out to be inspected, the best of gaskets you can buy were used and also we went with the ARP head studs to clamp everything down. Since everything was torn down it was a great opportunity to change a few other things when in Rome. I had them do a Fleece Bosch CP3 conversion kit to not have any worries in the future about a glitter party in the fuel system. Piece of mind 100% and money well spent. At the same time a new GM water pump, thermostats X2, tensioner pulley, serpentine belt and glow plugs were installed. Last but not least was a new turbo, PPE up pipes and ceramic coated manifolds to let the new RDS 64MM Turbo whistle like no tomorrow 👌. I also had them install a Kryptonite ultimate front end kit on the truck along with their upper control arms and new FOX shocks. I am completely happy beyond my wildest dreams. It’s running absolutely fantastic and is one healthy unit that is OEM + and gonna run for many more years to come. Their knowledge and experience speaks for itself. I highly recommend these guys if you ever need some general maintenance performed or some hard engine surgery done. You will be in great hands and will have piece of mind knowing that they stand by there work. Special thanks to Nate for doing the majority of the build process on the truck and Matt for doing all the organizing. Thanks again guys 🤘🤙!!!

Brought my truck into Precision Diesel due to my truck warning me it was going to shut off and not start back up in 250-300km.

They were extremely understanding of my situation and very helpful, they made sure to get me in as quickly as possible so I could get back to work, and they did an amazing job on my truck with a whole new exhaust system (which I asked for they did not attempt to pressure me into buying anything).

Highly recommend them, and will certainly be going back to them in the future!

I must say: I collect classic cars, one of which was a Hummer H1, on my last visit to Ottawa my H1 didn’t want to start, I had to take it to precious Diesel, and these guys started to work on it right away when they knew I was only a visitor was passing by Ottawa, it took them about 5hrs to put my H1 back on the road, I met the team who worked on my H1, and truly speaking these guys are super honest and they work from a good heart, I spoke to the guy who was working on my truck and he was a sweet and explained everything, and BTW they gave me the option to put temporarily switch to start my truck and get to my own Mechanic in Montreal, or to continue to find me the solution which they did, owning a classic cars means you are in&out of many garages, these guys charged my so very little for what I thought it would be over $1k and more, I know an honest mechanic when I see one and I saw a few at this garage, btw at the hotel where I stayed I asked the taxi drivers and the towing guy and others who knew this garage and strongly recommend it,
GO NOWHERE
THIS IS THE DIESEL GARAGE YOU NEED
Thank you Matt and everyone of your team,
Cheers
