Hi,
Cause of rear end seal leakage of Engine, I added a full bottle ( about 1/2 ltr) of Engine Seal Liquidat first time during this Summer , it stopped right away. On next oil change before November, I added this Engine seal same size bottle but did not stop leaking. All the time I use Synthetic Oil- Pl. note.
Now Can I add another extra Bottle of Engine Seal to my Engine Oil or not.?? Also Is it neccessary to drain the oil ( about same quantity- I add) or leave it in the Engine if it will not effect any thing..

Pl. let me know these TWO things,

Thnaks in advance

i agree... the thing to do is just do it right and replace it. there's been many a time that i didn't want to put the cash out for something like that but it's sometimes unavoidable.

 

just like pt Barnum said there is a sucker born every minute ! plus if their is going to be a leak synthetic oil will find it ! especially on a old engine . i am afraid the only way is to replace the seal .

 

I have heard of 'rings in a bottle' but 'seals in a bottle'? Come on, thats just silly.

 

Engine Oil Stop leak.....In My Opinion......is great stuff if used on the proper type of leak, and if the leak isn't too far gone. Engine mains are a great candidate for engine stop leak. Usually what happens in an older engine, is the seal will become rigid and won't seal around the crankshaft. Oil stop leak will soften the seal up, aiding in its ability to stop the oil from leaking.
I usually tell people to first use a bottle from a well known company. I recomend using Wynn's Xtend. Plan on spending around $15-$20 for the stuff. If you are going to use synthetic, make sure it is compatible with it. Change the oil, and add the bottle to the new oil. This ensures you get the maximum usage out of it.
Now the oil won't instantly stop leaking, they usually take around 500km to start working as it relies on the oil leaking passed the gasket to accually get on the gasket.

ALKA...to answer your 2 questions, I wouldn't add a 2nd bottle to the oil you already have in the crankcase. You should change the oil, and add the bottle at when you are putting fresh oil into the engine. And if the leak does not stop after the 3rd try, then the leak is too far gone and you need to replace the seal

 

I have seen some seals stop leaking after the first try, and have never seen them back, I have also seen some take up to 3 bottle to work and you see them back in a year or so. You never know if the stuff will work or not untill you try it, and there is really no adverse effects from trying it.

I agree that it will eventually have to be done, and that it is far better to just replace the seal, but think of the family of 6.....come in for an oil change, find out the rear main is leaking, they don't have $600-$700 to fix their older vehicle right away. But they do have $15 to try a bottle of stop leak that might fix it permanantly, or buy them a year or two so they can save some dough.

I worked in a small shop for a while, and we weren't about selling the big job unless they really had to be done. We looked out for the interest of the customer, and that involved trying oil stop leak on a lot of vehicles. They didn't work on all the vehicles we tried them on, but you'd be surprised at how many it did work on.
