Hi all, I'm in s. Florida and due to various circumstances, only have put about 500 miles on my 70 gs 455 in the last year or so. the motor is stock, and I have no paperwork indicating what work was done when. This weekend found oil pooling on the top of my timing chain cover where the screw tunnel is. Have not pinpointed exact location of leak. not certain if its the cover gasket or the manifold gasket or something else. but assuming it the cover gasket, I will need to remove the timing cover and all that is involved with that. If this in fact happens, seems to makes sense to be prepared and take care of some other maintenance and install new parts to avoid future problems. I am thinking I should buy an new timing chain just in case. Also thinking should replace water pump. Is there anything else I should be considering renewing since this work will be done? Let me know your thoughts and where relevant, please recommend the preferred manufacturer, ie. Flowkooler vs. Edelbrock or AC Delco.
