sb collant leak at timing cover??

Here's a plan replace the timing chain and gears with a double roller chain set, also replace the water pump.

This will be the reason to pull the timing cover to inspect it for corrosion and replace it if it needs it.

Beware the outer bolts can become stuck in the cover.

While the front of the engine is clear of accessories replace the freeze plugs also.

Belts, oil & filter too. Might as well replace the plugs, rotor & cap while doing a compression test also. What the heck valve cover gaskets too.

Have fun getting to know your SB
