Hello everyone,
I'm writing about the oil pump for classics. I have a 1966 v8. About six months ago I was driving and suddenly lost oil pressure. My lifters started ticking, the whole works. I removed the distributor and sure enough, the oil pump shaft had snapped. When I removed the shaft, it was stisted through the entire length of the shaft, very uniformed. Using a longer screwdriver that accepts bits, I added a new shaft and worked the oil pump free again. This has happened maybe 7 times. In December 2007 I decided to pull the oil pan and completely replace the pump. I cleaned everything out and replaced everything. I bought a reinforced shaft thinking I'd outwitted the car. Sure engough a month later, same issue. I've replaced it another 3 times since then and it's beginning to become a problem. This is my daily driver and I keep it in good condition.
So my thoughts are that there's something that's getting lodged in the oil pump. Some debree is in the oil and gets into the pump seizing it up. When I changed the oil pump (and oil of course) I noticed that the screen that roughly filters out the oil going to the pump was covered in a film or layer of pulp-like material that I was thinking might have come from a gasket. In any case, this was cleaned. I had thought at that time that it was plausible that the oil pump was becoming starved for oil. I had considered this until last night when, once again, the shaft breaks and I try to work the pump loose and each direction, as I move the pump, (from above) becomes tighter and tighter as though something is inside the pump it's self. I'm thinking that there are some metal shavings from somewhere getting into the oil. Maybe the rings as they wear?
Is there anyone out there that has had this problem? Has found a solution? I'm to the point that I'm ready to just rebuild the engine. If you have any ideas, suggestions, or experience with this problem please let me know.
Thanks !
