How can I stop a rear oil seal leak without having to have it replaced. I was told to put brake fluid in it.?

I was told to put a bottle of brake fluid in with the oil, it would cause the seals to swell and slow down the leak.How can I stop a rear oil seal leak without having to have it replaced. I was told to put brake fluid in it.?
Engine rear main oil seals have very little if any oil pressure to them and they are high up in the crank case. And have a drain hole between the rear main bearing and the seal letting oil drain back into the crankcase. So if it's an excessive oil leak my experience is that you either have main bearing wear or excessive pressure in the crank case. Check the engine pcv system and crank case vent too. If all is good replace the seal but don't put brake fluid in it. And don't ask the dealer. they will laugh you right out of the shop. Also be sure that's where the oil is coming from. I have seen many times where an engine had an upper engine oil leak and running down the inside of the bell housing making it appear that the rear main was leaking.How can I stop a rear oil seal leak without having to have it replaced.

The only real fix, is to repair it!





Anything else is throwing $$ away!
Not sure how well that would work,usually theres a rubber gasket which in that case brake fluid would not effect it at all, since thiers many rubber components in the brake system.Personally i would take it to a mechanic before you consider putting brake fluid into it , since its not the recommended fluid you would put in could be doing more harm than good. Stop Leak its a expoxy puddy brand just take a piece off and press form it into the leaking area and it should cover up or atleast help.
Sure, put brake fluid in your engine....it will fix your seal seeing as your entire engine will have to be rebuilt making it very easy to replace your seal in the process. Forget thos additives that say they can fix leaks like that, if they can swell a seal, they weaken it, and if it is already damaged, that will likely be enough to make it go out all together. There is no such thing as a ';Mechanic in a Can';.
Replacing the seal is the only effective solution. Yes it cost a few bucks but as the present one deteriorates from wear you will be pumping the oil right out the engine.





CAUTION - brake fluid in the engine is not a good idea. It has some solvent characteristics and it is flammable. You will only cause more damage to you engine.
That might be a short term { very short } Because the brake fluid makes it swell because it is breaking down the rubber and once it gets to a certain point it will fall apart and run , not leak out. Fix it right or if its a slow leak ignore it for a couple more months until the weather is better . But then get it fixed. By the way you will notice that a brake system is sealed ,, it keeps moisture out of the brake fluid because brake fluid attracts water.Not good in an engine.
I can not believe an auto tech student has suggested using a stop leak product!!!!!!!!!!





As a mechanic I have seen heaps of rear seal leaks and heaps of attempts to fix, one has proven the most effective and all others have failed.





Get it replaced, if stop leak products were so good they would be incorporated into all engine oils at the refinery stage.
