Timing Chain Guides
My suggestion, if you believe in the slightest way that you have metal-to-metal contact from time chain guide failure then get them replaced...immediately. If they are failed then you are putting your engine at risk.
I had mine fail at 198K miles in catastrophic fashion. The shop that does my work did a comprehensive diagnostic to ensure that nothing was damaged. If your timing chain cannot keep the engine in time then you risk having a valve contact something it is not suppose to. There was no contact in my case but inspection proved there was visible metal particulate in the oil, circulating throughout the engine and putting other parts at risk. Compression was within 5% of stock thanks to oil changes every 6K miles.
I now have 246K on the engine.
Having the problem properly diagnosed is cheap insurance. I hope this helps.
