lead gas additive causing sediment??

[cj71z]

I'm having a suspicion that my lead additive I was using from redline is reacting with the gas causing insoluble sediment. Recently I drained and cleaned the tank because of sediment that I thought was rust, found no rust. I put it back together, clean gas, filter etc. ran for a couple tanks with no additive, then I put it in for about 4 tanks. I checked my filter last week and it was full of this same sediment(brownish/red chunks that when you rub turn to powder) so I changed it, haven't run lead additive for 2 tanks and the filter is still nearly clean. Anybody ever had this problem before?

No, I haven't heard of this before.

Question: Why are you using lead additive, anyway? Do you still have the soft intake seats in your head?

My father has a Model A Ford. We recently had to flush the tank because a lead additive had be added in the past. Evidently some additives settle/separate if left standing for a time. Was a real clogger.

Arne-I'm using lead additive because I still have the original head and I don't believe it's ever had the guides/ seats replaced. I don't really have the time or money right now for a machine shop.:disappoin Zthing- Did the sediment turn to powder when rubbed?
