Bad timing chain symptoms4/10/2023 ![]() I had an issue with a car once that according to a mechanic "friend" needed a "valve job". Thats all I got.ĭon't want to be all negative nancy, but I would start preparing for the worst. Find a reputable shop (ask your instructor maybe?) and take it in, ask your folks/friends for help in the meantime. I ended up with a brand new lease (that I paid way too much for never owning anything), not enough miles to cover, that resulted in my not driving "my" car for the last year before I turned it. Turned into a motor replacement that went bad, that I "couldn't be without because it was my daily", that ended in me trading it in for what I owed on it which wasn't much, and eating the cost of the motor replacement on my credit card. Been there, done that, been in your situation before. I'm not saying its going to be cheap, easy, or quick, but I know what won't be cheap, easy and quick and that's if something major breaks before you can get it looked at. ![]() To me that sounds like something hitting something it shouldn't in the valve train. ![]() I'm not good enough to diagnose what that sound is, but that is NOT what I thought it might have been. Seriously, daily driver or not, I wouldn't be driving that again until I was driving it to a repair shop. But now I am thinking of looking into this "memory saver" thing before I work on the t-stat.Īnyways, that was off topic. In ours the battery was replaced maybe a year ago, and I don't recall anything happening as a result. I don't get the battery thing, but just recently I've been seeing posts about how disconnecting it can mess things up. Lots of swearing and cut up hands later, we got it done, but there must of been a much easier way. If you think its the water pump and you decide you want to do it yourself, look up the proper way to do it, which I think involves removing a bunch of stuff from the front end or the radiator or something. Of course it could be another pulley bearing or something else. Replaced the pump, nasty noise went away. A simple up down tug, and it was pretty evident. She couldn't remember the something else, but deduction led us to the fan clutch, which is attached to the water pump. Of course we had the dealer replace the fan clutch way back when, and they told my wife that something else was going to be a problem, but she could wait and fix it later. It was a while ago, but I believe this is how we diagnosed it in ours. If it does, the bearings are probably going, hence your noise. With everything off, and the battery disconnected for safety's sake, I would try and wiggle the fan up/down. That is a ridiculous job and well beyond my mechanical abilities. I am really not about to replace this timing chain and tensioner. ![]() I would really appreciate some expert advice from you guys. I really do not want this to happen because I love my trailblazer and it's my first car. My instructor told me that my engine is a ticking time bomb and the chain will break at any time and destroy my engine. I go to school for automotive mechanics and my instructor at school informed me he thinks it is my timing chain tensioner that has failed and I agreed with him because that is what I thought it was for the past year or so. But after you get it up to speeds like after 25 mph you can't even hear the noise, like I said it runs great. Months or so you would only hear the noise randomly at idle, nothing else but now the noise is prevalent at all times until higher rpms. Here's the other weird part, it has been doing it the past 5 years or so but until the last 6. The funny thing is I am not throwing any check engine light codes, it runs great, it just makes this weird noise. Until about 2,000 Rpms the noise gets louder but after 2000 it stops. My engine makes a really hard noise to describe and I'll try to describe it as best as possible. My parents bought the vehicle new back in 03 and my parents gave me the car 2 years ago when i got my license. Hey guys I would appreciate some advice for my 2003 Chevy trailblazer 4.2 with 158,000 miles.
