I took my truck to my mechanic last weekend because it was running very bad when the engine was not very warm. He called me back today to say that he thinks I need a valve job becase the valves on a couple of the cylinders are not seating properly when the engine is not warm. He said he would try adjusting the valves and get them to work better, but he didn't sound too confident of this working. It should be noted that my mechanic speciallizes in older land cruisers like these, so I have a decent amount of trust in his opinion.
My questions are: Is there anything specific that usually causes this problem? What is a reasonable range to pay for this kind of work? Is there anything else I should have him do while he is doing the valve job? Are there any other ways to try to fix this type of problem before taking the deep dive and doing the full job?
Please don't torch me too bad if I have any of this worded incorrectly as I don't have a whole lot of experience working on cars. I tried searching the archives, but didn't find a whole lot of answers to my questions.
It's going to be a sad day if he calls back and breaks me the bad news on the valve job. I've only owned the truck for 6 months, and since it only has 111,000 miles I thought I would have better luck avoiding major service items like this, but I guess you never know.
Thanks in advance for any advice/feedback. This board is awesome.
