Inlet valve guide
Inlet valve guide for the T120/T120R cylinder head, also listed as E3827.
70-3827 is the inlet valve guide listed for the T120 and T120R cylinder head. It's the pressed-in guide the inlet valve stem rides in, keeping the valve centered as it opens and closes and giving it a wear surface separate from the softer head casting. This is the same part carried in older parts books under the E3827 number.

This one shows up across catalog appearances from 1960 through 1971, always in the cylinder block and head section for the T120/T120R. When you're replacing guides, check the fit against your actual head rather than going by year alone, since head castings and guide wear vary machine to machine.
If you're doing valve work anyway, it's worth having the guide checked for bore wear and reaming clearance at the same time as the valve and seat, since a worn guide can throw off seating even with a fresh valve.
