He said his chemical tank wouldn't touch it. But it is all cleaned out and now put back together.
Let me add to what rocky has said, IH as well as others used glyptal to coat the inside of engines and transmissions to keep oil from "soaking" into the metal and to aid in oil dripping back dowm to the oil pan, or as in the trans case let oil travel down channels to bearing. The coating is pretty healthy, and will stand up to oils, but paint and primer will bubble and peel in these situations, if applied thick enough, which aint good!! A pice of that comes off, gets in a bearings, and it could very well be catastrophic!!raymonddurban said:Sorry for jumping in on the conversation late, but what was the issue with the coating on the inside of the block and why did it need to be removed?
