Hi there.It's hard to come in at the tail end of a repair not knowing what was the original problem and how it was repaired. I might be able to help, but I'll need to know the background on why the chain was replaced. Also, do you have access to a scan tool that will read engine parameter indicator data?
Customer: replied 10 months ago.
The top of the tensioner broke. Engine ran fine just made the rattling sound at idle. Cams were locked while the chain and tensioner was replaced.

I have no check engine light on either.

Are you done?

I'm sorry, I had asked if you had a scan tool that could read engine data, to see if we could determine what the issue was. Do you ?
Customer: replied 10 months ago.
I have no scan tool.
