“Sounds like a set up.”
It’s generally expected that a mechanic will do whatever repairs you need, provided they have the tools, time, and capability. But once in a while, your friendly auto tech might refuse a job.
A Toyota Camry owner pulled into a Florida repair shop asking for a new timing chain, a new oil pump, new water pump, and the engine resealed from top to bottom. The mechanic scanned the car, test drove it, and turned the work down.
Plant City, Florida-based Mozalez Auto Repair (@mozalez_autorepair), whose channel documents jobs and situations at the shop, explained what happened in a recent post. “This is a new one for me,” he says.
The car is a 2004 Camry. He asked whether there was something specific the owner was chasing, and the customer replied, “It needs it, it’s at the mileage.”
He was not sold. He points at an odometer reading of 111,000 miles, then reports what the diagnostic scan returned. “I scanned it, not one code,” he says. He drove the car as well. “It drives phenomenally.”
“Why are you gonna open up a perfectly good system?” he says. “It doesn’t make any sense. Do people just change timing chains just because?”
So he passed on it. “I’m gonna have to pass on this one,” he says. “I mean, it’s good money, but why?”
What Toyota Says About Timing Chains
Toyota’s own guidance suggests his assessment was correct. “If your vehicle is equipped with a timing chain rather than a timing belt, there is no prescribed replacement interval,” the company tells owners.
Belt-driven engines are a different matter, and Toyota points those owners to the Warranty and Maintenance Guide for inspection and replacement intervals, warning that “should the timing belt break while you are driving the vehicle, severe engine damage could result.”
A belt has a service interval and a chain does not, which is why “it’s at the mileage” is an argument that only works on one of them. One commenter compressed the whole point into four words: “Chains no, belts yes,” wrote paxtoncamaro91.
The One Reason To Open This Engine
There actually is a documented reason to go inside a 2004 Camry engine, but it’s not the chain. Toyota issued a service bulletin, covering 2002 to 2006 Camrys. “Some vehicles equipped with the 2AZ-FE engine may exhibit damaged cylinder head bolts,” it reads, directing technicians to “install Time Sert thread repair inserts into the cylinder block.”
Gluppybubble made this exact point, and used it as a reason to leave the timing alone. “Don’t fix what’s not broken, especially an engine that is known for head bolts pulling out of the threads in the engine block,” they wrote. “At that rate I would do the time certs.”
The Shop Floor Is Split
Mechanics in the comments did not all agree, and the creator even hit like on several replies that argued with him. “Just do what they ask. Use OEM parts and Toyota sealant,” wrote n8ivepatriot. “I do all my own work, but if I took my truck in for this work and the mechanic questioned me, the work would leave.”
Ag_autotech951 also made the customer-retention case. “Hey, I’d do it. Change the phaser and timing kit with OEM, seal it with Renzosil and it’s good to go,” they wrote. “I have customers who are very picky with their vehicles and take very good care of them. Take care of them and you’ll have loyal customers for life.” Diagguy.llc was blunter: “I’m doing it and we charging double.”
Others were down with his refusal. “I would pass on it too. You did the right thing,” wrote ike5156, who suggested playing for time: “I would tell them we will talk about it after the next oil change, and the next oil change after that.” Mingomacc, a mechanic, was suspicious of the request itself: “Only a mechanic that’s thirsty and wants the money would do that job, but it sounds like a set up.”
Others made the case that prevention is better than cure. “It’s known as preventative maintenance, staying ahead of breakdowns before they happen, instead of being stuck on the side of the road somewhere and adding a tow bill on top of it,” wrote francisco.isaac01. “Which is also the reason that ’04 is still running strong.” Westcoasttori answered in a line: “Timing chain is not a maintenance item on this car.”
The Baseline He Was Measured Against
The thread filled with people calling him honest, which says something about what drivers expect. AAA found in a 2016 survey that “two out of three US drivers do not trust auto repair shops in general.” The most common reason, given by 76% of them, was shops “recommending unnecessary services.”
In this case the unnecessary service came in with the customer, and the shop sent it out the door again.
