Is there a plug at the end of the tensioners shaft that's suppose to in? Mine has developed an oil leak there and the lock down nut.

Yes. It is shown in the video being removed at the beginning and installed at the end of the other repair video referenced.

Why did you have to replace just the upper chain?

@bryanwelsh1773 4 ай бұрын

I didn't replace the upper chain. It stayed in the engine. If you are asking why I changed just the upper chain tensioner it was because it was worn out, cracked, and leaving black plastic bits in the oil pan so clearly needed replacing, and I figured I could do it without removing the engine. If you needed to replace the other (cam A) tensioner, then you need to disassemble the engine, which of course would be quite a chore.

@@yashsamant6090 Welcome. For what it's worth, the lower tensioner didn't look bad from the angle I could see it. It doesn't have the same form factor as the upper, which has quite a bend to it. So maybe not under as much wear and stress.
