Oil leaking from R/H Timing Chain Housing on Heat Exchanger

[1976 TN Porsche]

I have an oil leak that seems to be coming from the R/H timing chain housing. Its leaking on the heat exchanger. The engine is a 3.2. I've installed RSR rocker arm shaft seals on the #4 cylinder exhaust rocker arm shaft but its still leaking. What other leaks could I be having in this area? Any help would be appreciated.

I haven't taken the cover off. But it is leaking at a steady pace out from what looks like the housing as pointed to in the picture.

If it is one of these can I take the cam gear off and the chain not slip off the crankshaft causing it to come out of time?

You are going to wind up having to re-time that camshaft. You can make your life easier by making sure that the right hand camshaft is in its timing position - TDC on #4 - prior to removing the sprocket. Lots of folks will try to tell you that you need to loosen up the rocker arms so the camshaft doesn't want to snap over out of time, but I have found I have never had to do this. In other words, you can time the camshaft with all of the rockers still in adjustment. This is not a difficult job in the least, but you do need to have an understanding of what is going on, and why. And the right tools...

proporsche identified this leak for me on my 1978SC. You need to remove the camshaft nut to get at the seals and be careful not to lose the timing. I bought the Stomski cam tool to do the job, much better than the crow's foot tool. Also good to have a dial gauge to check that timing is correct before and after cam nut removal. The job can be done with the engine in the car, at least that's what I did.

the last thing before you get to this double check you alu.seal on right side camshaft fitting here.....marked with black arrow,you might be lucky ...but generally this is a sign of camshaft cover o ring and gasket

Thanks All!

Although it's not your issue your valve covers seems to be over tightened causing the gasket to be squeezed out.

Agree.

I torqued them to 6 ft-lbs.

I just went through the cam cover gasket change. If you know what you are doing with cams that is great. If not, you should get someone who knows what they are doing. It is not a simple gasket change.
