Engine repair service near Brea, CA

Jesse and his team are top notch! I have been bringing my nissan altima to M&J for the past year and very happy with the work and attention to detail. 5 stars!

Not happy with this place or the work, took my M3 there one time, and that was all it took. First off I had plenty of work done, header install, carbon intake installed, water pump, coolant hoses, O2 sensors, thermostat, crankshaft seal, and instructed him to repair the oil leaks. Ed says he repaired my oil leaks, yet my car continues to leak oil, he damaged a $400 wheel, which he said, if the shop he knew, could not fix it, he would buy me a new one. When his shop failed to do so, I asked about a new wheel, of course he then said, he had no money to get me a new one, so I paid out of my pocket for a new wheel. I had him install my carbon air box, and he removed my OEM clamps, threw them away and replaced them with some junk hose clamps, stating he did not have the tool to replace the clamps, not sure what that has to do with me. So I took my car to check on the oil leaks and was told and shown by the shop, how the oil pan was not only missing bolts, but some were sheared off from over torquing, I was also missing header and sway bar bolts from his header install, my power steering hose was not secure, causing it to rub on part of the motor, damaging it, there were a few other things he failed to do, now costing me over a $1000 to repair after paying him over $2000 for less than subpar work. Do yourself a favor, and stay away.

Brought my vehicle in to have it diagnosed because it didn't pass the smog test. In short, dropped my vehicle off at 9:30 am, he didn't have it ready for me until after 4 pm. Billed me over $100 for 1.2 hours of work. When I picked my vehicle up, the drivers side window was stuck half way down. Couldn't roll it all the way up or all the way down. When I asked the mechanic if he could take a look at he told me he couldn't look at it because he had "other" customers and I would have to either leave it or bring it back in the morning. Told him I needed my vehicle for work. That didn't matter to him. Ended up taking my vehicle to a friends who was able to remove the door panel and fix the problem in about 30 minutes. In summary, they had my vehicle for 7 hours for a diagnostics check that took a little over an hour, was charged over $100 for that diagnostic check and then wouldn't take 30 minutes of their precious time to take a look at a problem that happened while they had the vehicle.
