Engine seal leak - Brake fluid cure? - [Thanks for all reply posts]
[Thanks to all for your posts on this.
No brake fluid for my motor oil!
I may have a look at the breather box after all.
Can't hurt.]
I've seen a suggestion re. a brake fluid cure for leaky engine seals. That is, add 6 oz DOT-4 brake fluid to the engine oil, change out after 300 miles - supposedly rejuvenates the seals. Improvement to be seen after about 100 miles.
Has anyone had success or failure with this treatment?
This could be useful for me, as my brick ('89 245 NA) has been leaving 4-6 inch puddles on the pavement when parked. It's the rear main seal. Flame trap system inc. brether box is verified clear.
I'd like to change to synthetic oil for the winter - With regular oil, I need a change every 3K miles or 3-4 weeks (long commute). It's no fun in the New England winter. Synthetic should get me through the season without oil changes. But I don't really want to feed a leaky seal at the price of synthetic oil.
TIA
