Engine repair service near Potrero, CA

I to took my car here and got screwed to .I had a tension pulley installed there in Dec 2012 ,cost me 260 and had a year warranty ,brought it back after taking it to a real mec that told me that the tension pulley was making this rattling noise .I took it back Econo lube and tune and told them that the pulley was bad,and left it there for the weekend. They called me and told me it was not the pulley ,but was my timing chain and would cost me 800.00 to fix it. I'm not having any more work done there and don't think anyone should.Bad customer service and bad mechanics. I also had my credit card numbers used at a store in mexico after visiting there in Dec to have my car fixed. They said they did an internal Investigation an could not pin point the person who used the card numbers. WoW, thats never happend to me before and it just so happened to happen 30 mins after leaving there place.Very unhappy with this place and don't recommend this place to anyone.

this guy wanted 80$ for leak checking some heads i brought in for an engine im building that needed work. i ended up just keeping the heads and using some rebuilt heads that i got an awsome deal on through some friends. 80$ is a JOKE! THATS ABSOLUTELY REDICULOUS!! ive found many machine shops that will look over your heads with a straight edge and a vaccum check them for FREE. they do not answer thier phones nor do they treat thier customers with any level of professionalism despite how polite you are in return. I have no intention of ever going back there again and I HIGHLY recommend staying away from these guys, thier way, WAY over priced. and are no where near being on the same level as some of the other machine shops around here i have deffinetely found better.
