Last summer I noticed some oil buildup on the top of my 85 930 engine while putting in a new fan housing. Thinking this was coming from the thermostat, I cleaned up the oil and replaced the thermostat and o-ring.
Recently I went to replace my alternator and noticed there is still some serious oil buildup on the top of the engine. So my first question is... where do you think this is coming from?
I’m hoping it is just the oil breather gasket but I can’t see under the CIS to verify. If I’m lucky and that’s all it is, how difficult is it to replace? What needs to be pulled to get access to it?
Thanks!
