White shepherd oilstop leak in my BMW

[Russell]

White shepherd oilstop 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 in my 95 BMW. Apparently a common problem.

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

Likely is, but if you go in with an open mind that it may buy you time before putting $ into a repair, while not my style, then so be it...

Let us know how it works.

You may be creating other/new problems, so just beware that there always is risk.

I understand, doubt if it will though. All reviews I read on BMWs, land rovers and similar etc. show no issues.
Actually my leak may be the lower end of the vanos hose. If this slows or stops the leak, it is not the vanos hose as it seals with wave washers not rubber or rubber like seals. Correct me if i am wrong.

This is exactly what the ATP AT-205 reseal fluid is like.

I wonder if they contain some of the same ester compounds??

what is ATP AT-205 reseal fluid. Sounds interesting

A guy on an e34 BMW forum stated the following:

"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"

Any truth that statement? If so, I would there would be problems with high mileage oils like Valvoline Maxlife which promotes seal swelling additives.

Could be. The additive is likely a more unbalanced dose than what would be found in an HM oil.

Thanks, I think i will drive it with the additive for about 200-300 miles and then change the oil. That way it should have completed all it's work.

It is either on the shelf of, or can be ordered by most NAPAs (or other comprehensively stocked, indie parts stores).

It is an ester solution which swells seals (engine, power steering, trans) in a controlled (as long as the dosage is correct

), which is used by many shop mechanics/techs, as are most of the other ATP branded products.

Wasting your money, first it is for seals, does nothing for gaskets

I tried it on two vehicles, wasted my money, leaks never changed. You have to keep the bottle and the receipt if you want your money back from them and I think it has to be in 60 days

I used the term gasket. Not really correct. The "seal" in question is a complex looking rubber like material. Hope it works. Only 110 miles on additive at this point.

I checked the oil drips for the past 3 days over paper towels. They are getting smaller every day. However I have only driven about 115 miles and about 90 minutes drive time. No impact on engine sounds or drivability. We shall see.

I have driven over 700 miles with White Shepherd in my crankcase. Looks like leakage is about 1/2 of what I had. It did help.

I now have about 2-4 small drops clustered in about a 6 inch circular area if the car is let set overnight Each drop is about 3/4 to 1 inch in diameter on paper towels I spread under the car. IMO, the leak is not reduced enough. I will need to fix it.

I used it to stop a leaky rear main seal in my 99 Sidekick when I had it. It worked very well for it. I have no complaints. Have to add it to a fresh oil change and it usually kicks in around 800- 1000 miles into it. No complaints here.

Interesting, then perhaps I can expect additional positive results as my mileage increases.

 

[Russell]

Today, I noticed only 2 small drops of less than 1/2 diameter. looks like the drops are becoming less over time. Perhaps this stuff does work given enough time/mileage.

Thanks for the review, i have a couple of vehicles i work on with leaky rear mains that are just not worth pulling the FWD transmission to get at.
I will give this a try.

Normally i wouldn't bother but in one of these the leak albeit small drips right into the start and wipes the brushes out at least once a year.
Nothing on the ground and no noticeable difference in the oil level on the stick.
