I would never use this product.

 

Rebuilding is fun.

No Leak is cheaper.

 

80 original 12a w/about 80-thou on it. Dowel leak slight, enough to fog side of engine in a week (so not a huge amount, just enough to drive me nuts trying to keep engine clean) treated with the No Leak. Noticed almost immediate improvement (couple 100mi). Now down to a few drops/week; been 2yrs/ 10K mi

Why? What are your thoughts jeff

 

Why use it? It's a band-aid fix. It's better to rebuild and get some new dowel pin o-rings in there. You have peace of mind, and it's fun to rebuild. I thought that would have been pretty obvious to anyone. But then the popularity of this thread speaks otherwise.

 

Some of us jeff dont have super time on our hands i my self would rather rebuild but its my only transport and have 4kids so no spare time i would like to give it a go but i have bad feelings about how the stuff effects rotor controll seals

 

Yes it very well could cause problems with oil seals. How bad is your dowel pin leak anyway? Can you live with it for while?

 

im not sure how bad it it is im still figureing it out

 

Well if it needs a rebuild anyway, why would you worry about what it does to the oil control ring o-rings? I would think it has the same effect and swells the rubber and seals better.
The temporary/band-aid fix "opinion" has been addressed quite well earlier in the thread.
I have 218k mi. on an 81 with a bad dowel pin leak. I will try the no leak, and if I get 10k leak free miles I will be happy. I tried some other stuff and can't recall the name but it didn't work.
