Guys,
I am working on my TR4 engine. The engine had blow by (#4 cyl) and a major leak at the front where the galley and front motor plate join. I built this motor in 1985. Had new piston/liners (86 mm), 20 under mains and 10 under pins, original cam and lifters, re-bushed rockers and new rocker shaft, new timing gears and chain. Maybe 10k miles since. I replaced the head gasket (leaking) in 1998 using Permatex Indian Head instead of the Permatex spray head gasket dressing I had used in 1985. The damage had already been done to #4 liner. This car sits a lot. Bottom line: I need to repair #4 liner and this leak on the engine front.
It appears that the oil galley plug that was installed in 1985 (block boiled) leaks. I immediately had a VERY significant leak in that area. Can the front motor plate gasket overcome this plug leaking? Did I simply fail to make a good seal on the front motor plate? Take a look at the pictures before and after cleaning. Where can these plugs be found? Google didn't really help me. I would like to start with this seal being rather leak free.
to me it looks like the top of the plug was leaking. The bottom (clean) picture shows a gap. What would you guys do?
Thanks,
Tim
