    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.

    A very common problem is the distributor O-Ring is leaking. Very easy to do & only the cost of an O-Ring.

    Look around the distributor as well but watch the fan in the DARK!!

    A one ounce bottle from any motor parts store (about $7.00-8.00) and I bought an LED blacklight flashlight (nice unit) off ebay for about $6.00. You can use it in anything oil based and there's also a water based compound for radiator etc. leaks. WORKS INSTANTANEOUSLY ! Add material, start car, and turn off lights. Let engine run and go over everything. Works on trans leaks as well as power steering, and I believe there's also a pressure can for A.C. systems as well. You'll be amazed at what you do or don't see!

    The valve cover pic above is off course the entrance for the dye and a FULL FLOW area for oil. I thought I also had an oil pump leak and a rear main leak, but alas, a little experience will show you how to read a leaker versus a weeper. The bottom pic is the oil pan/torque converter cover area with a very slight migration of the dye through really old oil (probably valve cover residue!). Parts have since been removed, cleaned and painted with no further indication of loss. GENERIC link below. ws
