My Trooper's leaking oil all over the place.

I'm trying out this stuff by White Shepherd. I hope it works.

I have always gotten good results from their Red Angel A/C system sealer, so if I was to try some oil stop leak, I would use their stuff.

Please tell me how well it works a few weeks from now.
 
Funny, I'm about to do the same exact thing..Just purchased a bottle of White Sheppard last night. going to put it in Friday night before I go out as you have to drive at least 1 hour straight for it to take affect. I'll report back as well about how it works.
 
I will report back. I'm VERY sceptical about this stuff stopping my oil pan leak like it claims it will do "permanently". I'll just be happy if it at least slows it a little. At first I didn't want to use it because from what I've know it the past, the stop leak products are very thick, but White Sheppard pours in and has the consistancy of water, so it's not like you are dumping a cup of peanut butter inside your crank case. I found this out when I opened the bottle and some of it spilled out on my finger.

I put some of that in with my last oil change to see if it would help my valve seals. It's been in there for 1300 miles so far and the smoke has descreased. It hasn't stopped completely though.
 
From my experience it works well on oil seals like front, rear engine seals, axle seals, gear box oil seals but will not work well on gaskets. It is a seal sweller as opposed to an oil thickener.

I have two bottles of the No Leak additive in my crankcase right now. Claims 2-3x the amount of additives that cheap brands have. We'll see if it stops my rear main seal leak.

The No Leak additive, and the Bar's Leak additives I've used were both fairly thin. I think the No Leak was probably thinner at room temperature than the 0W-40 I mixed it with.

Hey Mark. How well did the White Sheppard work for you?
