Westlotorn, I'm just thinking aloud as a DIY'er...do valve stem seals last the life of the engine? If not, why target only the leaking seals (valve cover gaskets etc) when that task covers a significant portion of valve stem seals replacement? The AGA tool is cheap to rent nowadays (approx. $200 for 2 weeks) … and if valve stem seals will eventually leak, I'd rather target them as well while doing the other seals, no?
