Help Needed Diagnosing Coolant and Oil Leak

[eacmen]

Oil's on the chain tensioner doesn't mean the tensioner is leaking -- leak from above can make it look dirty. I would remove the VC and if reuse the gasket if it's still soft. Clean all RTV and redo again, making sure to add some at the VANOS/head seams, and the cover corners. I don't use RTV on all gasket surface.

This.

I had what I thought was 100 percent chance of an oil leak on the tensioner. It wasn't leaking. Turned out to be the lower left VANOS-to-head bolt. It was a fresh VANOS gasket, so we took the VANOS off, put a tiny bit of FIPG on that lower left area and it was dry ever since. Only way I was able to see it was with UV dye and an inspection mirror.

This guy? From what I can tell from above, it seems dry and I can't spin it .

Not the left side - I said the right side.

Not on the haft moons but at the moon corners, and the vanos/head seam lines.

What’s the oil dye that people use to diagnose these leaks?
