Cliffs notes:
- Got swap together last weekend. Seemingly ran well. Did a few rippers before it slightly overheated, suspected because coolant lines weren't bled. Parked it.
- Next day went to change oil, noticed oil sprayed all over the back of the engine. Drained oil and only 1.5qt came back out. Put more in, started the car, and oil overflowed from radiator a few seconds later.
- Removed head, found a hole between oil and coolant passages. Filled with epoxy, let dry for a couple days, was rock hard.
- Found the chingy oil feed line was leaking. Had a shop make a new one and the leak was fixed.
- Put it all back together the same way it was before. Vacuum lines, coolant hoses, wiring, etc is all back where it was. Mechanical timing is perfect. Ignition timing is still too advanced with distributor fully retarded.
- Have got a code 10 twice out of 20-30+ starts (IAT error IIRC)
- Starts rough, plugs eventually foul, when I pull the plugs I can see a liquid in the cylinders but not sure exactly what it is (yet).
- Idles low at start, speeds up to the proper 750rpm, still rough and usually 1 or 2 cylinders will skip occasionally, sometimes they skip more than fire. After it gets near operating temp it eventually just suddent dies. After dying it's hard to start
- Oil is in the new radiator, but oil level in engine doesnt seem to be going down. Am not sure if this is oil left from last time or new.
- Timing is correct. For sure. Definitely. See pictures above.
- Firing order is correct. Positively set properly. Without a doubt.
- I have a td68u distributor, 22t water pump, gsr oil pump, gsr timing belt, gsr plugs/wires
- Have tried a different FPR to make sure it wasn't failed.
- Put screwdriver from my ear to the injectors to make sure I could hear them open/close
- Spark plugs are black/sooty. A couple times i pulled them out they were dripping wet, thought it was gas but it wouldnt burn?
- Am running a GSR basemap on a chipped P28 with O2 disabled. It worked fine the first time I put it together and nothing has changed with it. Solid CEL when service connector is jumped, no CEL when it's not.
- First time it ran (with correct ignition timing), I had to turn the distributor all the way forward for ignition timing to line up. Now, all the way forward is not enough.
I'm not sure how it went from running great, despite a couple problems, to running like shit when the problems were fixed.
Expect a big "for sale" thread coming from me soon so I can get some money to buy a known-good block and head. Just need to get previous sold item shipped before I sell anything more...
Still open to ideas but it sounds like numerous problems...
