Quinlin Automotive

"Quinlin has been my choice for several years. Always prompt service and excellent machine work."

"Took a clean performance cylinder head in for some fresh guides . I supplied the guides . Valves were loose in the guides when I handed them off . This came off a running engine . They said a couple weeks . I called in about 10 days later to make sure they put a fine finish when they faced the head . They said the guides were out - but not done yet . I called back a week later to ask if done and they said it was done 2 days after I dropped it off ? Valves were in a box when I picked it up . Got home to find a bent exhaust valve- WTH. Also had a guide that I couldn’t get a valve in ? How does this not get noticed? I also noticed they only changed 6 of the 12 guides- charged me for 12 ? Where are my guides ? They apologized but had no reason for the bent valve - NLA from Manley . Never offered to pay for valve but said they would do it over again and install the other six valve guides . They did offer to meet me to save travel time but I’d rather have had it done right the first time . When I started to install valves I found eyebrow marks in the combustion chamber by the exhaust valve that was replaced . Again- no explanation . I’ll never use them again . Oh- and it seems all my valve heights are different . I guess they weren’t checked"

"I’ve always had great experiences with this shop! They’ve fixed alot of bad work from other shops in the past and would highly recommend using them!"

"Great prices! Honest work! They assembled my block along with other request!"

"Took Fooooorrrrever to get my block done (13 months), gave me back rusty/dirty parts and forgot to shot blast the block like i requested before they did the machine work. Crankshaft grind is sub par, the fillet area of the crank wasn't even fully ground leaving a ledge in the center of the fillet and then not oiled and left to rust, Never again. Schmidt racing engines and warrior racing engines are the only shops that will get my money from now on. Pictures showing examples of the work, condition of parts, and how i received the parts back Update after i got my block back. basically every dimension they machined was incorrect. asked for the pistons .008" down and got .011 and .014, asked for .003" rod clearance and i got .0015", asked for .005" cylinder wall clearance and got .0035-.0037. after an hour of me bringing my tools to the shop and showing him what was wrong dan "agreed" to "fix" the issues after i told them exactly how much material to take off of each surface and still couldnt get it right! cylinder number 3 has .0062" clearance where the rest are at .005 like i asked. dan reground the rod journals another .010 under (making them .020 under) and only had .002 clearance. deck was within acceptable tolerance but only after i had to tell him exactly how much material to remove. told me after he was finished dont come back to the shop. Dan Quinlin is a hack, avoid at all costs."
