@Citrus Cruiser so far yours is the only picture of the early valve train with the oil shields in tact! Not even catalogs (e.g. SOR) show them. And even though there’s been some success from folks swapping out the o-ring rubber seal with the umbrella rubber seal of later F engines (and 2Fs I think), those shields look to be essential in keeping the oil out of the valves. (To use the umbrella seals the inner spring needs to go away, so there’s a long term spring issue that might become a factor). Those rubber seals wipe the valve shafts, but there’s still oil pooling potential at the base of the valve seat. I guess the community has accepted the increased oil burn and bit of smoking from not having those oil shields in place. I can’t imagine that toyota was behind this but maybe there’s some service bulletin somewhere out there that talks this.
Looks like I’m in this boat, as I doubt there’s any of those shields floating around. I hope I can get the smoking down to something like the occasional puff.
