white shepherd oil stop leak

White shepherd oil stop leak is used to stop oil leaks. Web review indicates it seems to work. About $16 at advance. It esssentially swells seals. I think the gasket where the oil fliter canister housing meets the block leaks. Apparently a common problem.

Just thought I would give it a try before I replace the gasket. It is odd stuff as it is clear water like. Money back if it des not work. May be just snake oil.

I'm not implying you are a kid, but you are someone's "kid". Or child, offspring, son, daughter, etc.

They do work by clogging up your whole engine with nasty deposits. I assume you never opened cooling system or engines up after using 'stop leaks' in a can?

You may be right. We shall see.
Do a little research to see if there are bad reports on "this" product. Ii did not find any bad reports. A few said it did not work for them but no mechanical problems.

This is why I decided to try it for giggles. If you find something let us know.

I just did some research, this is basically a brake fluid solution that expands rubber (would not work for flat non rubber gaskets).

The only thing that bothers me is the lifetime of gasket after it's dissolved in brake fluid which nobody seems to address.

Edit: I would advise flushing the system out with a high mileage oil now to remove improper oil balance from your system.

Thanks. I saw somewhere that it used something similar to brake fluid. Are brake fluid seals different material than most engine seals.

I currently use Pennzoil HM oil and have used Maxlife HM oil. I will watch closely and go from there.

BTW, i see you are an engineer. My son is a civil and by nature he proceeds carefully in all he does.

The brake fluid is a 'trick' that mechanics use to fix gaskets for a long time, basically they put dab of brake fluid on rubber gasket it gaskets rubber will 'bloat/expand' so in theory it will seal better.

The addictive you added is 'basically' a brake fluid that goes into your oil and makes any rubber parts inside your engine (seals?) expand. It's a proven method to make seals expand but again I don't know how it affects rubbers life time or heat or friction resistance/etc.

I recommend changing oil because you are now running oil mixed with this addictive which removes lubrication additives and thins your oil. If you used it for a bit it should already did it job with gaskets (expanding them) no need to run this mixture in your engine now, flush it out and put fresh oil in.

Could you just live with the leak a little longer until you get the correct part and can afford to do a proper repair either doing it yourself or taking it to a shop? I can't imagine it's pouring all over the place.

The problem with a "fix-in-can" is the company can give you money back sure, but they won't give you your engine back. A global approach like that affects the entire lube system and can't guarantee it won't have negative consequence a few years down the road elsewhere in the motor. Just thinking prudence here.

appreciate the concern. i can afford to fix most anything on this car as per my wife, "it has an open checkbook" and she does not. .

Thanks, It has been in the engine for about 30 miles. I will wait a few days before I change oil etc. to ensure full effect on gaskets.

Hey man I just want to tell you nicely since it is your car, the cheap way is generally never the good way. BMW's teach you this time after time. That crap you dont want in your engine man. Have you ever seen the inside of a tire after someone puts "Fix a flat" in it? Same principle applies here. Just dont want you to have to replace an engine for stuff like this. I mean $16 and your engine could go. Idk man just my opinion.

I understand. As I have said, I have done my research, this is nothing like" fix a flat". The material is a thin clear liquid designed to swell seals. Similar to Valvoline Maxlife High mileage oils.

IMO, the worst that can happen is nothing. If there is any negative change, even on my way home from work today, the stuff will come out.

Alright just makin sure. Hope it works. Idk why BMWs straight 6's leak oil so often. I changed every oil gasket on my E34 525i except the canister gasket, and it leaked. I replaced it with an E39 and it needs a pan gasket and other things. My E34 540i has had no such problem, at all. Idk but good luck man.

The worst will be is that good seals in your engine will expand and become weaker and you will have to replace them in a year or two along with seal that was leaking. :P

Interesting concept. Do you have info or a link to proof? Think I will ask this on bobistheoilguy forum. If correct, it seems as if Maxlife HM oil would create long term damage as it promotes seal swelling. Just sayin.

I don't think high mileage oil has brake fluid like addictive in it AFAIK. I don't have proof and nobody seems to touch this subject but brake fluid does damage integrity of rubber that's not a question.

The question is how much does this damage impact life time span of said rubber, since you can't really perform this test with perfect mixing of engine oil/brake fluid at exact specifications your motor can and see how much exposure the seals are getting it's just a guessing game now unless engine is torn apart before and after.

So true, a guessing game

Personally, I try to stay away from quick fixes like that if I can avoid it. But I have used rat-poop pellets in many a cooling system until I had been able to replace what was wrong

The only time I would tell some one specifically to stay away from a given product is if it had a proven track record of failure or I had a bad experience with it. IE, Steel-Seal... Stay far away LOL...
