In the middle of a stock 1600 rebuild and after lapping the valves several times, I decided to check if any were leaking, so I turned the heads up-side-down and put some water in the top of the cylinder (so the water is sitting in the cylinder against the valves like a cup) and after a few minutes water starts dripping from one of the ports, usually the intake port, the exhausts seem OK right now, even though one exhaust seat has a small chunk missing.
Green lines illustrate where it is dripping from.
I am guessing that this is not normal or something that would improve once the engine is together and under correct pressures etc?
What do you guys think?
Do the Valve seats need re-cutting / replacing? If so, how much would that cost?
Weak springs? - How do I test them, just buy more and hope that solves it? (trying to rebuild the engine on a budget as it is a temporary engine).
Any ideas?
