honestly, i wouldn't ask francisco. hes a nice dude but for business its a different story. i had my valves adjusted by him a while back but they were still ticking. i got my car looked at by other people and they said that it didn't seem to be adjusted. talked to him about it and asked if he could look at it, but he said he would charge me again. if you do go to him, make sure that you are there watching him do it. and if you can get someone who knows it well to see the process, that would be great. goodluck
