Engine leak sealer

[offcrusin]

OK folks, I know everybody hates the pour in additive
To seal engine leaks but does anyone have any first hand
experience as to if the additives work and engine leaks
or are they just introducing more problems?
Thanks for the feedback

Don't do it and don't use an engine oil flush either, you will regret it.

No, don't.
If there are any particles/grunge in your oil passage lines any 'sealant' will tend to build up in that area too possibly blocking off or restricting your oil flow.
Not a good thing.
Quick fix's have numerous negative issues much like the fine print on drugs...may cause greasy flatulence...or death.

I by no means am an expert but three questions come to mind.

1) Where are you leaking oil from?

2) How much is leaking?

And

3) What type of oil are you using?

Naturally some oil leaks are addressed by replacing gaskets, seals, warped covers etc . . .

In my case, driving the car more frequently and changing the oil to Brad Penn (and later Shell Rotella) drastically reduced the amount of oil I would drip. Personal discussions I've had with engine rebuilders have steered me away from ever introducing those additives to my system for reasons outlined above.

Good Luck

As other said don't do it. You can use heavier oil if you are burning it till you can do a refresh. I used to run strait 50wt oil in my old vw bus to slow the consumption. If you have a old tired motor NEVER put synthetic in it. It will eventually find its way out and start new leaks.
Good luck and remember that these are very expensive motors and using cheap tricks usually don't work and could cost you more in the end.
