Question for 6 owners, Bolt sitting between head and chain tensioner housing?? Options

[Jeffs9146]

I was changing my oil and I notice a leak coming from between the valve cover and the back of the chain tensioner housing!

There are no leaks on the top of the motor and no leaks from the oil return tubes but there is a gap between the back of the housing and the head that has a bolt in it. I have read that there can be a leak from the rocker arm pivot shaft that is in the general area.

So the question is could the rocker shaft bolt have fallen out and be the bolt that is between the valve cover and the tensioner housing?

Here is a photo of the bolt and where the leak seems to be!

It is entirely possible it is the bolt out of the center of the rocker arm. But I can't tell from the picture. Best way is to take the valve cover off and take a look.

Make sure you drain the oil first. When the engine is off, the tank will drain back to the sump, and it fills up the lower end of the valve covers too.
