I have a 1969 350/350 original block which leaks oil from the timing chain cover Oil pan area.
Bought the car no leaks. Hit the drain plug somehow (I think backing off the trailer) and had to have the oil pan replaced. This is when the issues started.
Had a mechanic replace the oil pan with a chrome one and kept original timing chain cover. Still leaked.
Had a mechanic Replace the original timing chain cover with Chrome and kept the Chrome oil pan. Still leaked in different areas.
Different mechanic told me I needed to replace both with genuine GM replacement Oil Pan and Timing chain cover with a 1 piece gasket. This is where I am today.
Still leaking worse than ever where the timing chain cover meets the oil pan. Someone told me to use oversized gasket. Not sure which to get. I am thinking of doing it myself this time and putting th original timing chain cover back on.
Any advice? Anyone had the same problem?
