Hi all,

Looking for opinions or experience any of you have with finding high aluminum content in your 4.6L 2v UOA reports or if any of you have experienced timing chain tensioner issues at similar miles. I'm at 138k miles and am the original owner of the car. I'm not hearing any abnormal sounds from the engine while cold or at temp.

Here is my Blackstone report with concern areas circled in red. Could the aluminum be the front engine cover? I find it hard to believe it could be the rod bearings.

Thanks,
Wade

Thanks, Wicked. It's got the nylon/plastic chain guides but those can become brittle over time I believe.

Anyone else have thoughts on what is more likely? Chain issue vs. bearings vs. pistons?

I've decided to move forward with getting the timing chain done along with water pump and radiator. I figured that will put my engine in good health for the eventual supercharging.

What kind of shape is your thrust bearing in?
