Thinking about using sea foam

[Stann90]

I have a 95 es300 .  Bought it with 110k now it has 340k on it . It's burning and leaking oil from the valve covers and probably from the front or rear main seal , cuz it has spots under it when I move it . I'm gonna replace the valve cover gasket but not confident on replacing the main seals on the v6 I've done timing jobs and seals on Hondas but never on Lexus . Also I'm using full synthetic mobile 1 I forgot what I put in 10-30 or 5-30. My question is what's the outcome of using sea foam on a high mile car like mine ?

Hi and welcome to LOC!

The only thing I can say about SeaFoam is that I used to work for an automotive warehouse and I sold pallets of the stuff.   It must be good.
