Question type: Maintenance & Repair

I don’t want to waste any more money, so need to find the root cause, so open
for suggestions….
Fix the seals to stop the smoke or is it something else the cause?

do a compression test and leak down test to see what's worn in the cylinder , there is no magic gunk that you can add to fix internal engine problems it has to be torn down
