Rear Main seal fix
Anyone ever use rear main seal repair chemical?
I read about White Shepherd and seems like a easy fix. Is it bad for your other seals?

JUNK all it can do is soften/swell the seal a bit. its supposed to cure seeps and drips, not a real leak.if the seal is nearly gone it will help for a short time, then get worse. the softening and swelling takes what little life is left and just kills it.

If your seal leak is minor, just a weep, you might consider trying a "High Mileage" recipe crank case lube, in the brand your now using & see if it'll make a positive difference.
It might slow or stop a mild leak for a while, until your in a better financial position to put the real fix on it, by having the seal replaced.
Some folks on the Ranger forum claim to have had positive results using Valvolene's high mileage recipe.
Make sure your PCV valve isn't clogged up & causing a crankcase over pressure condition, as that can cause weeps or leaks by forcing lube past weak, or worn seals or gaskets.
I think your wise to be careful about adding aftermarket chemicals to the crankcase, as we don't know what or how much of any item is in them, nor how what is in there will affect our engine oils synergy, or effect other seals, gaskets, or metals.
Unlike the "High Mileage" recipe motor oils, these after market products don't have to meet any specs, or go through any tests, so long term effects are unknown.
More thoughts for pondering, let us know how it goes.
