Oil Leak

[AMR33]

I was driving and started smelling burning oil, opened the bonnet and there was oil leaking onto the exhaust manifold. Took rocker covers off and the gaskets were certainly leaking and I'm in the process of replacing them. Was wondering if this leak could be caused by something else, any ideas? Motor is rb20

Pretty common issue, can't think of anywhere else it would leak from, apart from perished crankcase breather hoses. When I did my rocker gaskets, I also had to put a dab of sealant on the leftmost passenger side bolt nearest the sill as it is also tapped through the head (oil passage). When re-installing covers, torque in sequence and to 4NM - Don't over tighten! Don't forget red Permatex for the half-moon seals too!
