Hi Guys,
I'm somewhat at a loss.
I've had my 64 falcon 170 engine redone by a machine shop,
basically, new pistons, new timing, head and block mating surfaces were flattend. (This was nescessary because there was some warping and the previous owner somehow ended up with a big scratch in the block mating surface.) The machine shop put it all together.
When I installed the engine and ran it for the first time I noticed coolant loss. Apparently there was an internal leak, the coolant ended up in the oil pan. About 1 a 1,5 litres (1 a 1,5 quart i guess) in one week.
After contact with the machine shop and some tests I pulled the head again.
The machine shop pressure tested the head and couldnt find any leaks.
With a new gasket, the leakage is less, but still there.
I figure it cant be the block, since the only thing that has changed is the gasket and the leakage has decreased.
I installed the head with guide pins in 2 of the outer bolts as described in the falcon shop manual.
Sunday I ran the engine again end afterwards I retorked the headbolts.
Today there was water in the oil pan.
In both cases the leakage occured before and after the engine had run.
What can be the cause.
- not wel fitting gasket?
- mating surfaces not flat enough?
- bolts bottoming out due to too much material removed when repairing scratch?
Help!
