    Default Need help sourcing 2TG/3TG engine parts

    I recently bought a 2T-GEU long block. Engine appears to be in pretty good shape -- however, one of the valve/retainer locks (keepers we call them here) was broken when I removed it. Hoping someone here can help find a source to purchase new valve keepers/locks. 8.5mm valve stem and 7 degree angle, single groove. Haven't been able to find an internet source yet. Pictures below.... Thanks -- Michael

    Planning on putting the DOHC cam head on the 3TC block that's in my TE21....

    Mike "try these" They may or may not be exact but they work for me. We have spoken before and your car still looks great...

    eBay item number:
    353302287179
    Seller assumes all responsibility for this listing.


    Note: 13741A P/N 90913-03010 is the listed item from the parts manual.

    Contact the folks here because if they sell valves and retainers, they should know or have a source for the valve locks for these items:

    Thanks for the reply!!!! How's life?

    Ebay says "not any exact matches" -- nothing comes up with that eBay item number......

    Edit --- oops --- got one number on the Toyota part number search incorrect; lemme try again.

    You sure about the eBay item number? BTW, I saw the other thread where you posted this info; same result with the eBay link.

    Titled under this search:
    8xPr.ITM/Repco#051-126,Toyota#90913-03005 Valve Keeper Sets 3KC,2TC,3RC,8RC,18RC

    Note: This is for the standard models listed within his title listing, however I based my choice on the fact that my 18rc and 18rg valves to me seem to fit together when I tried to match them, I would caution you that these are not to same exact part number as the correct valve lock for the 2TG and 18RG....

    Copy as written and you will find them!

    Also you can search this link as I do, daily:

    https://auctions.yahoo.co.jp/search/...lg=1&b=1&n=100

    Valve spring retainers are available at this site:

    http://www.kameariengineworks.co.jp/CONTENTS-2.html

    pages 41 - 46 cover the 2TG and 18RG... Some pages have an English sector on the far right of the catalog!

    Thanks for being patient with me. It's interesting - if I put that eBay item number in eBay's search bar I get nothing. If I search "eBay 353302287179" using my search engine (bing or google) it pulls up the item you're referring to. In the listing picture - the inside looks just like the inside of mine. Dimensions are the key. I haven't come across another Toyota engine that uses a valve stem that is that large a diameter (8.5mm) - within .01" of the same size as a big block Chevy. I'll do some more research and see what I find. Thanks again - M

    First pass, I don't think the eBay parts will work -- the description lists them as fitting 2TB, 2TC among others. If you go here - https://www.toymods.org.au/forums/th...s-amp-Diagrams - and scroll down to post number 4, you'll see the 2TC valve stem diameter is 7.96-7.98mm. The 2TG stem dia is 8.46-8.48mm. FYI

    You are almost correct: stem size is 8.40mm.
    I just measured a set of Used valves from a 2TG both the intake and exhaust valve stems measured the same.
    Intake:


    Exhaust:


    And the valve spring retainer opening is 13.50mm top of keeper and 10.40mm at the bottom opening...



    I also checked the specifications for the 2TC specs and you are correct on the stated valve stem diameter for that valve, sorry that I had not taken the time to check the Green book prior to suggesting a possible fix for your situation.

    I also have another suggestion, for what it is worth. These are Yamaha Heads used for this engine, could that be a source for the correct valve lock provided for this application?

    May want to check the calibration on your digital caliper --- mine reads 1.000" on a machinists 1.000" test piece that goes with my vernier calipers.

    Mine is correct for valves from a 1973 2TG not 2T-GEU Single valve spring, not the duel valve springs. I would rather not disassemble a 2T_GEU head to remeasure or disassemble a 3TG just to prove a point..

    Good luck with your search, You have got time or could also order some custom replacements as an assembly..

    Ah - so the stem size changes also - between 2TG and 2T-GEU it appears....
