[W126 Coupe] FW: Engine Leak Stop

It sounded from Doc's thread that he said that he was burning oil, not
leaking oil. A puff of smoke on cold startup and smoking from the tailpipe
at stoplights, IMHO, is most likely valve stem/guide seals. These seals get
hard as stone after several years and no longer do their job, allowing oil
to wick down the valve stem or be drawn In during the intake stroke.

In 40 years of playing with cars I have yet to have an oil leak from a head
gasket...
I would go by a oe valve cover gasket and redo the valve cover. Its a 10
minute job and cheap.
I'd put a small wager that your oil leak problem started about a year ago!

No valve covers were redone about a year back..I see you r point on the head
gaskets as the location would not be conducive to the burn off I am getting.
The rear main may be leaking as well.

Anyway anything to slow it would be better than nothing

Any suggestions on a good engine stop leak additive?
Engine is very strong and I would rather not rebuild at this time. No need
she runs great.

Heads gasket leaks are causing some smoking when sitting at lights etc. due
to dripping to the pipes.
Would like to try to slow it down a little if anyone has some ideas.

Thank you,
Doc
