rags Posted November 26, 2002 Share Posted November 26, 2002 Fuel pump ruptured would be my first guess. Joe Quote Link to comment Share on other sites More sharing options...
Guest soulfly454 Posted November 26, 2002 Share Posted November 26, 2002 well i kida figured it my have something to do with my fule pump and oh yeah its electric if that matters Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 27, 2002 Share Posted November 27, 2002 I would suspect raw gas is seeping into your crank case from the carburator since your fuel pump is not mechanical. Carburator and it's float(s) may need adjusting. Could be excessive fuel pressure too from that electric pump.. Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted November 27, 2002 Share Posted November 27, 2002 If starting the car is an every day routine, how long do you let it run? I assume you are not driving it. If it is just a short time, like 5 minutes, that is not enough time to let the car warm up and build heat in the oil and cylinders. The carb is probably staying in choke a long time dumping a very rich mixture in the motor and causing lots of raw gas to blow by the rings, right into the oil. You are better off just letting it sit until you can drive it. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted November 27, 2002 Share Posted November 27, 2002 Does the engine have high milage on it? If so, then I would agree with Greimann on this one. The rings are probably shot and its leaking past them when its cold. That's my $.02 Quote Link to comment Share on other sites More sharing options...
Guest gbvol54 Posted November 27, 2002 Share Posted November 27, 2002 Had a similar problem on a older boat. Left over the winter, bow up (fuel tank in bow), without the Coast Guard required checkvalve in the fuel line. Result was fuel pressure to the carb (thought slight) sufficient to allow fuel to flow through carb and rings into crankcase. A good flushing and proper check valve got the old girl running just fine. Moral of story is that it could be a relatively simple fuel issue such as those suggested above.

Guest Anonymous Posted November 27, 2002 Share Posted November 27, 2002 I gotta agree with Gary on this one.It sounds like a lot of fuel is in there,to turn 5+ quarts of oil into brown fuel.When you did your conversion,did you do something with the tank vent or return line that would prohibit the tank from breathing?My 75 280 has 3 lines coming from the tank to the nose.The one that goes to the charcoal canister is the vent.Maybe the line got kinked in the wreck.Remember that change in temp can create pressure.Try loosening the gas cap during the warmest time of the day.If you release pressure,the tank is not venting.If the nose is lower than the tank,it will be gravity fed into the carb.Good luck Quote Link to comment Share on other sites More sharing options...
Guest Slvrhase Posted November 28, 2002 Share Posted November 28, 2002 I think berZerker is correct. I did a V-8 conversion on a GM I once had: capped all the "extra" lines coming from the tank, everthing hooked up and running, let the car set for about a week, there was so much gas in the crankcase I had to change main seals. Learned that lesson the hard way, the tank has to release pressure some how. This is something I am concerned about on my conversion also, the "search" has many answers!

Heh, I left a line open to "vent" and the damned gas evaporated! Sealing it up the tank ballooned up Not sure how best to set it up now...

Guest Slvrhase Posted November 28, 2002 Share Posted November 28, 2002 It makes you almost want to run all those crazy hoses back and forth, in and out of the vent/expansion tank and know for a fact that it will work. To me, there really seems to be no other correct fix. Quote Link to comment Share on other sites More sharing options...
