serious timing chain issue/safeguard suggestion
Well this is really bad news, I was getting timing chain codes, except for a hard start the engine was running fine.
I thought I would try the tensioner before I did the entire chain, when I opened her up, man what a surprise.
There is a metal guard on the top of the timing chain, for some unknown reason this broke in two, one piece snapped off, the engine pulverized it, it entered the engine, scored lifters, smashed timing chain guides and who knows what else underneath, like possibly the crank.
I have 85,000 relatively mild miles, the only thing out of the ordinary, I am a salesperson and starts are 30 times more then normal
My mechanic has no idea what caused this guide to fail, he thinks a failing tensioner might drain when the engine is stopped, and maybe the timing chain jumps around on start striking the guide.
don't know
anyway, when up in mileage, and you have occasion to get under the valve cover, do look to see if this guide has strike marks, if so, might as well replace that metal guide.
This is bad guys, I am not messing with bandaids, rebuilding doesn't make sense as a new engine is about the same price
I hope this is a unicorn, if not, I sure hope I can prevent this from happening to others
