Q: Q: oil leak

asked by on

I have an oil leak, 99% sure it's the rear main seal. I've tried the liquid Bar's stop leak to no effect. SO - If the oil filter is bypassed or the element is removed - to NOT catch anything or get plugged up - can the powdery stop leak sold in the clear plastic tube (copper color, very fine particles), used for RADIATORS be mixed, in small amounts, to a quart of oil and then added to the engine? I'm unable to just stop and do the repair - don't have any alternative & have to use this leaking sob daily. I know it sounds a bit crazy, but if it doesn't get caught up in the filter, would it have a chance of lodging in the leak without engine problems? The powder is super fine, but I don't know the chem properties, clotting factors, etc. I'm not a formally trained mech, but have worked on every vehicle I've owned (150+) as well as friends, etc. Also, have an engineering degree (25 yrs ago) but have never used it for employment. Please give this some thought- let me know what you think
