Cobra 305 fuel pump replacement

[RV Parker]

Gentlemen, I replaced the fuel pump on my 1988 cobra. Due to rusted bolts I could only remove the old pump and had to work from there. In order to keep the push rod up after trying several differant techniques that did not work I used a small amount of plumbers putty to hold it up untill I could get the new pump on. I did put a spot of grease on the rod end and pump lever end. I then started the motor and it seemed to run fine. I now worry about that small amount of putty in the system. Do you think it will affect any parts of the oiling system or just dissolve in the oil? Thanks

Really hard to say.
This is obviously not the intended use for plumbers putty. Bearings aren't intended to be lubricated with plumbers putty. No telling if plumbers putty is oil soluble.

If this were presented to me, I would seriously consider pulling the pump again, and cleaning the contents out. Then I would probably be doing a bunch of oil changes afterwards. No guarantees that what you did didn't just wreck the bearings or clog oil passages and oil pump pickup. The only thing that should be in the crank case besides the parts of the engine is oil.
