Underbucket shims

[eight-six]

Totta - The set up you have described sounds identical to the shim/bucket set up found on the late spec 3sgte (and possibly other engines)

Its an under bucket arrangment with a small shim that sits in the spring retainer recess under the bucket - the shim is about 10mm across or there abouts from memory.

The shims can be found on 1994 onwards SW20 turbo or a ST205 GT4.

Sounds like you have confirmed what I stated a whle back that the under bucket arrangement on the late 3SGTE will also fit the 4AGE head.

Your looking at about £40 for a full set of shims for the head - Toyota can supply them in every size but you will need to get 1 first so you can work out the tolerances and what you need for the rest of the 16 valves.

I will see if I have any spares kicking around in the garage from the last gte rebuild i did.
