## Questions & Answers

**Q: will this mix with other stop leak ?**
A: I am not sure, but I would call Bar's Leak Tech Service at Call tech support:800-345-6572 (M-F, 8a -5p EST) You can also go to their site Bar's Leak.com and lookn at their FAQ section

**Q: Ok for ford 6.9 idi diesel ?Eng overheated-very slight combustion leak in cooling sys,no white smoke,oil clean. Is1 bottle enough for eng 8gal cap?**
A: yes also try engine restore to stop your combustion leak it works well with 6.9 idi 

my blow by was so bad it blew off the oil cap once but after engine restore 8 cylinder it actually brought the compression backup to factory only drawback is you must use it every oil change

**Q: will it plug the heater core?**
A: I have a 1995 Honda Odyssey, 4 cylinders.  Blown head gasket, puffs of steam out the tailpipe, small geyser from the radiator.  Used Blue Devil, following all instructions, and about 80% better but still some steam out the tailpipe and smaller bubbles in the coolant.  As per tech advice from Blue Devil I took out the spark plug from the offending chamber and ran for 50 minutes.  I did this aggravation twice. Still leak.  So I got this product, flushed the system using Prestone chemical flush, keep the thermostat out and then put in the Ba's Leak HG-1.  I only used bout 40% of the bottle and diluted it about 3:1 with distilled water and antifreeze.  Did this because it was so thick.  Followed instructions, initial run was difficult because it was not circulating well and was running hot.  But the second session went fine after top off.  After the fourth cycle I looked into the running radiator and there were no more bubbles and no more steam out the back.  Success!

However, my heater core is clogged.  No big deal as this is California.  Question: can I eventually restore the heater core by back flushing the cooling system?  I wouldn't do this till the Fall.  In the past K Seal had pugged up my heater core and I recoverd most of the function by back flushing (Firestone, $120).

**Q: Do I have to keep using it or is it a one and done type of deal?**
A: It worked for me. 2005 impala v6. One bottle saved it from the crusher. Mechanics want 2000$usd for the replacement of head gaskets. The car ran badly for a while and still used some water but after a few drives it works fine. The check engine light even finally turned off. It was worth the price even just to avoid towing this again, but it keeps running!
