You'd think they'd make something to last.....

I bought a 49,000 mile 78 power wagon off the original owner, the valve covers leaked so bad the engine was a total grease ball.
I pressure washed the powertrain for like 4 hrs to get the grease build up off the engine, trans and transfer case.
When done a soft-plug on the head stated leaking, the grease kept if from leaking.
It was an untouched engine, still had the orange 1978 date code plug wires on it.
