Alright so in my '51 Styleline I have replaced the starter/fuel pump/lines and got some ugly but usable wheels until I free some funds for nice ones. It's now actually useable and I have been driving it every couple of days to work or out on errands but there is one small issue I haven't tackled yet... There is always a little pool of oil under the car the next morning, not a HUGE amount but enough to have me wanting to fix it. I am planning on doing an oil/filter change anyway but more concerning is the fact I popped the hood and saw oil had been getting by the valve-cover cap. I had cleaned the motor down the day before and now the rear half of the cover is slick with oil, not drowning in it but definitely has a leak. I haven't got a huge amount of experience in these motors, is this a known issue on a full pressure (1960-1961) 235? Or do I have a concern here? I've seen a little get by valve cover caps before on other cars but this seems worse, is this a symptom of something bigger? Any advice would be useful, I don't get much time to work on the car so I need to be efficient with what I can look at and fix.
