Hi all,
Whelp, things aren't as done as I want them to be. I got the engine sewn back together, including an unexpected fuel filter change. While changing it, I filled it up with Seafoam for the hell of it, bled everything and started the engine.
It started OK, chugged some white smoke, but started knocking almost immediately. I let it run for a minute, reading that sometimes running Seafoam through the engine can have that effect, but it keeps happening.
At first, it would struggle to idle, intermittently dying out.
Now, symptoms are like this:
- Starts right up, sometimes idles beautifully. Sometimes idles with varying degrees of power/slight RPM changes, but no knocking.
- In idle, it throttles up just fine, hits expected RPMs, and can rev back down without issue.
- In gear, it doesn't knock immediately after shifting but starts knocking as it throttles up. The knocking then persists to idle, which is inconsistent/hard idling while in gear. Occasionally dies when RPMs are reduced to idle.
- Grey exhaust and unburnt fuel on the water throughout all of the above.
- Temperatures are good and expected (at least on the gauge)
- Oil levels are good
- I just changed the trans fluid to spec
Troubleshooting steps:
- Tried bleeding the fuel lines again, both at the knurled knob and also by loosening the fuel injector heads until fuel spurted, a la Christian Williams' previous post.
I think I'm at the point of calling in the pros to take a look, but curious if anything seems obvious or overseen here.
