I've got a small drip started and it is collecting right at the lower edge of the timing case cover where it meets the valve cover. Based on the "oil trail" it looks to be creeping along the lower edge of the timing case cover. The valve cover gasket was changed just a few years ago so I'm pretty sure it's not coming from there. Also the oil pump was redone a couple of years ago and it's not a drip that comes from the oil pump (I'm familiar with that one!).
I'm thinking I may have to pop off the timing case cover and re-seat it. I notice it has not gasket so I assume usual metal-on-metal sealants to be used. Is that correct? Also I notice that there is a shaft seal for the shaft coming into the space - while the cover is off should I go ahead and replace that seal? Is that a realtively straightforward job or does it get complicated?
Any advice is appreciated!!
