:seeya I've just been hanging out in Off Topic for the last couple years. :lol: C6? As in Vette? Maybe but not right away, going to enjoy the Goat for a while. If Cruise In 6 then I don't think so, unfortunately it is at a time that makes traveling very difficult for me. :nonod: Would definitely love to though. :yesnod:

those tabs, veg-all as i like to call them , have been required in many gm products for a long time. started when the use of aluminum for blocks really got going... i have no problem with and as a matter of fact have used the product for years... alumi-seal is another outstanding product....

your problem was very minor, the front plug, as you found out... easy fix..... remember that the other side head has the same deal only in the rear of the engine...

to bad you dont trust your dealer .... you should find one that you do....

Lots of vehicles come from the factory with stop-leak and Bars Leak is one of the most common, domestic and foreign. I use it and have for decades in iron and aluminum engines with zero problems.

BUT, GM should fix the problem you have--plain and simple. Research has shown we pay thousands per vehicle for our warrantees, used or not. You have a reason. USE IT, you already paid for it! :yesnod:

Hopefully they(GM) will not void your warranty for unauthorized repair by owner.Good luck hope no future issues.Just noticed this is old thread.
