Appreciate all the input and suggestions. Thing is, it sealed before not sure why it wouldn't again if I can get it done right. I've reinstalled the oem one and used Indian head shellac. We'll see. I do wonder how long I should let it dry?
Did you check to make sure it was flat or did you just ignore that suggestion?
They do warp over time and you can tighten the bolts all you want, if it's cupped it will not seal.
Why did it seal before ?? thicker gasket, more sealer that was allowed to fully cure before coolant being added again ?
