Immediately after hooking up the leak down tester, I could hear air coming out of the exhaust. And the leak down gauge said 100% leak. This is with the rockers taken off, so valves should definitely have been closed. I tried rotating the valves to see if it would ever seal up better, but it won't.
So I assume I have something like a bent valve or a cracked head. Does that sound right? Would it be anything else?
At this point, I think my options are:
- Bring the head to a local diesel shop to be rebuilt
- Buy a rebuilt or new head off ebay
