4age 16v large port valvetrain question

Postby Nick94tt » Mon Apr 06, 2020 6:01 pm

Went to reassemble the head and realized I'm 7 valve spring seat / locators short. Normally I'd expect to lose springs, lol. :lol:

Could only track down the 20v variant.

13734-16020

Doubt I'm lucky enough that they interchange between the 16v large port and the 20v motors, but there were a ton of domestic shim on bucket toyotas.

Anyone know?

13734-16010 is what you are after... 20V and 16V not interchangeable. I have some spares...

And....

My 7 disc out of place ass half crawled under the deck to fish around with magnets. I found 3 screws and a bottle cap. :evil:

After figuring out a jig to wire brush my valves and knocking that out, tossed the head on the table.

Turns out I'm not missing any valve spring seats. They were buried in varnish locked into the head.

FML :lol:

OST - Thanks again and so much for the fast response and offer. Owe you a beer should the world not end and you see the east coast.

Hopefully my idiot shenanigans help someone else remember to keep the damned bits attached to the parts. :mrgreen:

At least there are part numbers... :lol:
