Engines R Us Pros

I received a great price on my first engine rebuild. However, soon after the motor began running, a lifter wore out and caused a misfire. The shop agreed to perform a second rebuild at no charge to fix the issue. Before they started the second rebuild, I informed them that the rocker arms were installed incorrectly; they were not aligned point-to-point and were failing to hit the center of the valve spring tops. The shop acknowledged this error and claimed it was fixed during the second rebuild. Upon bringing the vehicle home, I decided to double-check their work. After removing the valve covers, I discovered the rocker arms were still installed incorrectly in the exact same manner. I have since removed them from both sides and corrected the alignment myself to prevent further damage.

Shop owner will do anything you can to not honor the warranty. Continues to advertise the six years, unlimited mileage warranty, but does not honor it three years out. Do yourself a favor and find another shop. These guys don’t deserve your business and will not honor the warranty they promise shame on you Jesse. shame on you, Ignacio! I have recommended your shop at least 50 times to vintage Toyota owners and I will no longer do so! Absolutely despicable

Don’t come here they will scam you! They said to fix the car it would be $7,000 to fix EVERYTHING. We paid & left the car there for a month, yes a whole month. No updates or any calls on what was getting fixed. Once we got it back within a day it started having problems again. We called them & told them about the problem & they told us to take it back. Once we got back they said something else was now messed up even though they had just “fixed it” & now wanted to charge us another $1000. Again we agreed to fixing it & it’s been yet another month. Now that the car is supposedly fixed they want us to pay another $600 for labor even though they told us they wouldn’t charge us again because of the first problem. It’s been around 2-3months of no car & no signs of getting it back. They are scamm

Ok it’s been 4 years and only 30,000 miles since I had my 2009 gmc sierra 1500 engine overhauled from the ground up, I can’t say enough to explain how happy I am with the service provided I was given a Diablo trinity 2 programmer and I disabled the AFM system I’m still going 22 miles per gallon at 80 plus mph, no leaks oil pressure is still descent oil and filter haves every 3,000 miles frank and his team are the best in the west this is coming from a 40 year automotive service consultant, I will write another review in another 4 years or so

Gave Frank over $18,000 to rebuild the motor in my motorhome. I drove 200 mi and The motor died. I had to pay an additional $3,000 to get it back to Pomona to his shop. Now he's trying to make every excuse in the world not to follow through and finish with it. Instead he says I'll get back to you. I went down there with another mechanic who called them on their padded bill and believe me this bill is really padded and I would love to give them a good review but they need to follow through with their warranty because there's no way I'm paying more money. I already paid $18,000 to get this motor rebuilt in my motorhome and now I'm getting the runaround and additional fees I had to pay. So I spent over $21,000 on rebuild and tows and my RV still doesn't run. I want to give you a better review
