Re: Hairline Crack in LM7 5.3 Block
Glad for the progress....
I use these tablets in both of my LS powered rides and have had zero issues. I believe they were originally formulated to seal small cracks in the alloy heads, but they work on cast iron very well... I add new tablets about every six months to ensure the continuing protection. ![]() ![]() ![]()
