hello, if it were me and i got a list like that i would start with the valve cover gasket. if that takes care of the leak which it might seeing how thats the highest point and those other things may look like they are leaking when its just oil running from the valve cover gasket.
if the valve cover gasket fixes it then you are good, you can consider the timing belt and water pump but honestly if the pump isnt leaking and the motor runs good i wouldnt mess with it, as a repair like that will end up costing about half of what the car is worth.
What is your opinion of the gasket sealers such as Thermagasket or K&W block sealer for fixing something like this? Is the valve cover gasket something a novice like myself could do otherwise?
Thanks.
i dont like the thought of adding those type of sealers myself, because whats to say they dont seal off an oil passage in the motor.
the valve cover gasket is a very simple job and as long as you have some hand tools you should be able to do it yourself. i look and see if i have the procedure for you.
