They suck. My engine is less than one year old and needs replacing already. These guys are hacks. Tijuana top tier mechanics.not USA grade work. read more

Blew my motor on a 2003 Toyota Tacoma and they rebuilt it for me. Vincent was very helpful

Castillo did it again. Went to take my car in for an inspection of the new engine they put in and get the oil filters changed and oil replaced. They immediately attended to my car, and it was done in no time. Very professional, great service, and my car has never run better. These guys are all you need for car repairs. read more

A great experience, I will definitely recommend this place to any of my family or friends who need engine repairs. read more

STAY AWAY!!! This place is terrible. I took my truck to have an engine rebuild...Two months later I got my truck back after tons of excuses why it took so long... Within a few months I had a minor oil leak. Texted Efren no response. Exactly 11 months go by and I had only driven the truck to and from work during cover and the engine is draining coolant and white smoke is coming from muffler and oil leak is horrendous. The engine was so bad I asked to bring it in because its under 18 month warranty. Major excuses were given and not to bring it in right now. I took it to my regular mechanic and he said the engine was completely ruined. Now I am stuck with a broken truck on a job that should have easily lasted 4 years. WASTED THOUSANDS...if you look at most of the good reviews they are from fake profiles. Efren is an ok guy to talk to in person but I think he is a chronic liar. He said that he served in the army so if that is true I thank him heavily for his service. It could be that this shop is just slammed and not enough workers however, my engine was not given any love at all. It came back taped together and with wrong fittings. read more

Castillo's engine rebuilding kicks mother fucking ass! When my ex-GF's ford expedition's engine died, the shop she went to wanted $4800 for a complete engine rebuild, this sounded extremely high. I went on yelp and searched for engine specialists. This place popped up with the best reviews so I recommended this to her, and they were able to get her a completely new engine for under $3000!! Apparently the engine got fucked up by engine oil of the wrong viscosity. Since she has been using pretty much just Jiffy Lube for oil change, it was most probably Jiffy Lube's fault the car. Fuck you! Jiffy Lube!! You are the reason I went to the Cal June from hell and despoiled my pristine and pure ASS!! (See my previous epic review of the Huntington Park Carl's Junior for more juicy details). Though the work took an extra week to complete than was promised, the workmanship was stellar, I will not hesitate to recommend others to come here if they need engine work done, these guys are da BOMB! read more

My dad got his 1993 Nissan motor done here a few years back so I tried them out. I've had my 1990 454 ss Silverado engine rebuild stock here may 2012 year and just did a 1990 mustang 5.0 performance build here month ago. I spoke to Vince and he is extremely knowledgeable. This guy knows his stuff. Trust! We build a 302 making 400+. Port, polishing, fabrication, budget or all out, Vince is your man! Even the turn around time was unbelievable. 2-4 days tops! I highly recommend Castillos. I plan on taking a 1970 302 boss engine to get rebuilt as soon as I stack up some money! read more

I need help I called David. He told me to call this the shop he will help you with everything you need Yes I called and Vince helped me and went Above and beyond customer service to help me Thank you and to all the members of #Beach Cities Mustang Club read more

Be very cautious when doing business with Castillo's Engine Rebuilding. They are crooked thieves and they will smile about it once they have your money. I'm a local and decided to take my vehicle for a minor issue and they recommended to have the engine rebuild because of the mileage. I had no major issues at all with my vehicle. The son "seemed" very knowledgable--you will find out that it's not him who does the rebuild, it's actually some Hispanic guys they hire and work on the car on the west side of the business--and threw many mechanical terms to sound credible. He probably has no hands on experience and just regurgitates what he reads or hears the actual mechanics say. I was convinced. They "rebuild it," it took it home and oil was leaking from the blowback. I took it back, "they fixed it," took it home and oil continued to leak. They said it was a small censor and needed it replaced but I need to buy the sensor at the dealer, I did so and same problem. They refused to fix it. Three independent mechanics stated that the overhaul was not done correctly and that Castillo most likely had the overhaul done somewhere else and they just assembled it at their shop but since their warranty expired with the shop they contracted, they acted like fools and kept blaming it on other "sensor issues." To summit up, I had to get my engine rebuilt at another shop. Yes, the shop did confirm that the overhaul was done incorrectly at Castillo's, thus, the reason for the blowback. I would recommend that if you are going to get work done at "Castillo's Thieves Rebuilding, " you are better off going somewhere else or donating the money you are about to waste to a charity. My guess is that they are in business because they take advantage of the Hispanic community that are unaware of the rights they have, such as referring them to the Better Business Bureau. read more

By far the most effective and helpful body shop I've ever worked with. Effren was absolutely amazing and went over and beyond to help fix my vehicle. Two other shops were not able to figure out the issue and Effren was the champ. He worked with me in every aspect of it all. I'm truly appreciative of everything that this shop did for me. It was a nightmare but they made it all better. I highly recommend this shop to everyone! Thank you again Effren you were a life saver! read more

I paid for a full engine rebuild on my 240sx at this place and a week after I had the engine "rebuilt" the oil plug comes off while I was driving in the freeway and all the oil spilled out on the freeway and endend up killing the engine. Towed the car back and they denied that they did a bad job and paid an additional 200 for a crankshaft on top of the 2300 I paid for the rebuild....after a year of driving the car I found out that they reused all my gaskets and seals when I paid to have everything replace... I will never come back to this place after this awful experience... read more

I had a horrible experience with this "so-called" machine shop. The owners, Vince and the dad, lack real automotive expertise. All they know is to collect your money and cannot complete the job. Call BAR or your attorney the minute they try to swindle you. Do not pay them until your car has been completed. Keep all of the documentation. Stay away! Stay away! They will beat around the bush because they don't know what they're saying. To the people who run this pathetic shop, quit pretending to be experts! read more

Soooo.... I took my truck, they gave me a receipt saying "CHECK AND CALL"... Two days, no calls, I had to go my self to see what was going on ....the owner son had a bitchy attitude to a female ... WTF they started working in my truck with no authorization..... They fix a small easy problem... But they didn't find out about the main problem, the noisy problem, the owner said... I didn't want to go deeper in to engine because I had no idea what could that be... JESUS ... Somebody talk to me what kind of ducking service is this ... GOOD LUCK !!!!! 32 YEARS OF PROFESSIONAL BS...THEY DON'T deserve a single star.... The owner's son has a problem dealing with customers ... read more

There are many machine shops to choose from, but Castillo's provides fast service and quality work. Efrain and Vicente are very helpful in getting the best results out of your engine. I appreciate that they are willing to find parts and answer any questions. My father and I have been coming here for over 10 years for our engine needs. Thank you again for your quality work!!! read more

I blew up my engine because I didn't check the oil. I couldn't afford to hire a mechanic to take the engine out, so I had to take it out myself. I called some other engine rebuilders but Castillo was the best price.They came to my house and picked the engine up. A couple weeks later they brought it back looking brand new. Efran was very helpful answering questions I had about putting it back in as I have never done this kind of work before. After I finishing installing the engine, I couldn't get it started, I had it towed to a mechanic, and he couldn't figure it out either, he called his friend to do some tests and the guy said it had low compression. I started freaking out, I called Efran, and he said send the car to him and he will figure it out. The next day he had it running, it turns out I had installed the distributor backwards. The low compression readings were because it was a brand new engine with perfectly smooth cylinder walls. Efran even had his guys tighten up some hoses I never did right. I would recommend them to anyone. read more

This guy knows his stuff. Helped a friend out. And I must say. I dont know anyone else who knows more about engines than Vince Jr. Good with prices, especially if you want it done right. You wont go wrong with visiting this place. read more

I had my classic car engine rebuilt just a little over a year ago and a rocker arm had already broke with just over 4k on the motor. I found a legit mechanic who also told me they reused my springs and other parts that Efran said were supposed to be all new parts? They also lost a bunch of original parts that I have to replace now. Basically they are a volume shop that lure you in with low prices and BS. I learned my lesson of you get what you pay for. read more
