3.4 from a 98 t100

I'd give you a prize for year/model/looks like a 3.4?
Try finding it on this site... https://toyota-usa.epc-data.com/

I've got these numbers, but it's off a '96 4Runner-thinking you have something different-

Not pictured- the forward IAC coolant hose to pipe (not attached to intake manifold but to the pipe behind it)- part# 16261-62060

engine is from a 1998 t100. 3.4 automatic trans 4x4

habanero! thanks so much for that site! found the part, i think. Crankshaft breather tube. 12262-62050 is anyone is interested. PM me if u want that mattress

No worries, glad to help where I can. Thanks for the offer, it's not necessary. My bike and junk sleeps in the truck anyway, so there's no room for me- or a mattress.

Can the prize for giving the year/model be...the answer you were able to find?
