The others certainly have a good suggestion with using an electric pump and wire it so if the oil pressure goes down it won't provide fuel. Hotrod and other can show you how.

Thanks very much. Might be just the solution I need. Question for me if whether I am getting fuel past the rings that is causing my problem. If the engine runs great, is that likely to be an issue?
I love the idea of a dummy fuel pump, assuming this is the problem to begin with.

The plugs were two steps hotter than factory and burned a hole in one of the pistons. Created a slight miss, hardly noticeable, but gained liquid in the crankcase every time it was run.
Good luck,

It's worth a try.

Pull the pump apart and look.
Joe | | | | | Joined: Dec 2011 Posts: 402 Shop Shark | | Shop Shark Joined: Dec 2011 Posts: 402 | I did have some blow-by coming from the draft tube recently. After a long drive (from Homecoming), I stopped at a gas station and filled up. Another driver saw a puddle under my truck and when I looked, it was under the right side of the engine, near the draft tube. But, by that time, I did not see anything dripping. So, I could not say 100% positive it was my truck, but it seemed logical.
I checked the puddle and it did smell just like the solvent oil I have in my engine. When I got home and parked (out in the gravel near my shed), I put a slab of cardboard underneath to see if anything was leaking. Next morning, there was a small puddle underneath the road draft tube.
Other the other hand, last time SWEET and I checked compression, it seemed to us that we had good compression on all cylinders (100-ish range). Might need to recheck that.
Do you have a procedure for a leak-down test? Would you recommend that?
As for the earlier questions on the fuel pump brands:
2 x Advance Auto (unknown maker)
1 x AutoZone (unknown make)
1 x NAPA (unknown make)
1 x Glass bowl type from Classic Chevy Truck Parts
Will absolutely do the electric fuel pump fix, but would like to examine the possibility that it's related to the rings.
Thanks for the help guys.

How does the exhaust smell? lean (really hot ), rich ( burn your eyes )?
Has the oil been changed each time the pump went bad? or did it correct it self though evaporation?
How about coolant, is it using any?
I can't figure why fuel will cause a draft tube drip, it should evaporate before getting that far. I understand the high oil level. but what exactly is dripping out? oil or water vapor?
Keep us posted, Joe. | | |
