Gas in Oil, Lots of gas in the oil Options

[sbruzek]

I've been trying to get a 1973 2.0 L to run. Its still got the original FI. I've replaced a bunch of parts. New plugs, points, wires, cap, rotor, coil, FI seals, the fuel pump, fuel filter, rebuild the relay board, swapped out the in line fuel pressure regulator (today) tested and now have 28 psi of fuel, and replaced all the vacum lines. I've tested the manifold pressure sensor and it holds a vacum and the resistance across the connector test out OK.

Like before most this work she will start right up cold, but run very rough and blow smoke, it will not idle, and stall after 3-4 minutes and then not restart. Looking into the throttle body its loaded with gas. I got it to run today for 10 minutes or so and it dumped about a quart of gas into the oil. I know how much because I had to drain the oil aftre seeing an oil leak from a valve cover. Leaking oil was very thin and full of gas. Amount drained out was 1 qt higher than I put in. This also happened last time I tied to get her started, gas in oil. It started better this time with repalce FPR but still large amounts of gas in the oil. It happens each time I try to get the 2.0 running. All the work and replaced parts so far have not solved the issue, mainly gas in oil, and running way to rich/stalling. The excess gas has to be the cause of everthing I would think.

I've already pulled the injectors and the cold start valve to see if any where stuck open and none were. It would seem that the extra gas can only be coming from the injectors or the cold start. I continue to suspect the cold start based on all the gas up in the throttle body under the air cleaner. Could the gas be shooting way up there from one or all the injectors??? Could something be telling the injectors to add that much gas?? It like its getting way to much gas ALL the time. Now it will rev high right away when you get air into the throtle body. It also did that when the cold start was off and open to let extra air in.

Any ideas??

Could a bad heat temp sensor cause this much gas to get injected?? It tests out OK and it happens with or without it conncted. How about the CU or throttle switch??

Any help would be appreciated.

make sure you pull all 5 injectors to run that test.
I would suspect the cold start injector, or the thermocouple that signals the cold start injector....

I assume the signal is a ground, it could even be a damaged wire from the thermocouple that is grounding on the case sending the signal.

I pulled all 5 and cranked it for 10 sec with coil disconnected. The cold start did not squirt any fuel ever. ( Temp in my garage is 65 F or so) The injectors all squirted the same amount into small glass jars. I did this 4 times to be sure and each time the volume in all 4 glasses looked the same, I did notice that 2 of the injectors "leaked" just abit when the fuel pump first ran, when the ignition was first turned on, but before I cranked the engine. None leaked after cranking was done.

I don't mind spending the $$ to have all the injectors refurbished if that fixes the gas in oil/rich running problem. I have already run this test once before after cleaning up the injectors myself with starting fluid and compressed air and that didn't fix the issue. I got the same results again this time so it seems the injectors are working OK duirng the test but not when the car is running??? What else could be the issue??

Trigger points or CPU giving injectors bad info??? Any sugestions on who to send the injectors to for refurbishng/testing??
