Advanced Auto carries it, I carry a bottle in my glove compartment.

 

Is the Lucas stuff comparable or does the white sheapard stand out from the crowd like seafoam?

 

Lucas works differently as far as I can tell all the Lucas stop leak products rely on thick oils to "block leaks". Stuff like White Shepards and Auto RX cleans up gunk around seals and conditions the seals. Also none of these products are miracle cures. Things like gaskets and RTV seals that are fairly easy to get to should just be replaced. But if you have a leaky rear engine seal or a bad power steering pump it can't hurt to spend $50 bucks and experiment a bit before you bow big money and or time on fixing the issue the old fashion way.

On a side note Seafoam is decent stuff for an induction cleaning (many say plain distilled water works even better, I will pass on that though). As far as cleaning your fuel injectors and and engine flushes goes there are much more effective products (Techron (FI), Auto RX (flush) seem to be the best). The one thing that bothers me about Seafoam is the price, $10 a bottle is too much for what you are buying. There are forums dedicated to this stuff and people have their favorites. I used seafoam for an induction cleaning and I got good results, you need to trickle is in real slow though or you are just blowing it through your system.

 

Ok great, thanks for that info that helps a lot. Ya i have a small leak that I believe is coming from the back of the engine because I can see some build up on the top of the catalatic converter.

 

Can't hurt to try it, it's not cheap though, $17 for 12 ounces. But if it works then it is worth the price.

 

Ya that was my thinking

 

Seriously?? White Shepard??? No issues?

 

Seriously! I have a 78 f250 monster that had a real bad transmission leak from the torque converter seal and it was ruining the whole street in front of my house. I bought some Lucas stuff as a last resort and it didn't do anything. The guy at the parts store said try the blue devil and I did and it haven't leaked a drop since. That was 6 months ago. I also used it on a rear main seal leak on my wifes old 03 Discovery. It worked within a day and never leaked again. Then she totaled it . When it was upside down in a trench I got a good look and it still wasn't leaking.
This is the only "fix in a bottle" I would ever buy or put in my car.

 

You should have them do the torque converter seal and put a gasket set and o rings on the transfer case. I would.

 

He may have, and he might not even own the truck any more...
