Hi.
Just purchased a 2006 r53 here in Sweden.
I took the car for a test drive before I bought it and heard a noise but it’s sounded like an exhaust leak in the headers which I though wouldn’t be an issue to fix being a steel fabricator. But now I am suspecting it’s not a leak but a noise coming from the engine.
Could anyone help diagnose this?

symtoms.
-Normal operating noise on cold start up.
-starts to be more apparent as the car warms up.

-Sound like a exhaust leak (couldn’t find one)
-found some traces of oil around the rocker cover gasket

I just bought a new timing chain tensioner for it which I’ll replace this week as I’ve read everywhere this could be the problem.

When I rev the car and hold it at 2000rpm it goes away.
