    IT MIGHT WORK--BUT IT IS RISKY-2 HOURS SOLID RUN TIME TO HARDEN ON HOLES--OR TWO HOURS TO FIX BY REPLACING THE PAN $70
    sorry to say it did not work--it slowed down the leak from 2-3 drops per second to once maybe 2 seconds--it is a liquid plastic that makes a plastic "ball" under the pan drip.--if you buy it you must understand----YOU MUST RUN THE CAR FOR 2 OR MORE HOURS --ALL AT ONE "CONTINUED 2 HOURS" DOES--NOT MEAN 15 MINUTES,,THEN ANOTHER 30--ETC...YOU MUST LEAVE THE ENGINE RUNNING FOR TWO + HOURS--THE COST IS AROUND $20 A BOTTLE- YOU MIGHT LOSE 2 QUARTS SO THE DRIP CAN APPLY THE PLASTIC. ACTUALLY HONESTLYTHE STANDARD BRAND $8 OIL LEAK STOP--WORK JUST AS WELL-JUST SLOWED IT DOWN. FINALLY WITH ALL SPENT ON STOP LEAK,,BLUE DEVIL--QTS OF OIL---------------I WOUND UP GETTING A NEW PAN FOR $60 AND GASKET (TUBE OR SIZED CORK) $12--SO FORABOUT $75 BUCKS--THE JOB IS DONE---I AM A FAIRLY GOOD BACK YARD MECHANIC(1)-20 MIN TO PUT ON RAMPS- (2)20 TO TAKE OFF16 OR 18 BOLTS.(3)-20 FOR SCRAPE,CLEAN,APPLY GASKET--AND(4) 20 TO PUT BACK-(5) (20)OF COURSE OIL DRAIN AND (6)REPLACE ANOTHER 20-- SO YOU ARE LOOKING AT 1 HOUR IF GOOD MECH--2 1/2-3 IF TOTAL AMATEUR-----BUT THEN YOU ARE DONE WITH THAT PROBLEM ---no short cuts with this BlueDevil unless you understand that you must keep the engine running for TWO solid non-stop hours--and when the oil and plastic sealer drips as you run engine--you better pour fresh oil in to replace the 1/2 quart you might lose every 1/2 hour in the two hour drip process.
