    You needed to adjust nearly all your clearances. so juggling them should give you some back in check.

    I wonder if the Co. HotShims makes a asst. for us?

    HotCams.

    No sorry, just motorcycles. (I just looked) I don't know why they never got into the auto. side.

    Many Toyota models use the same OD if you can find a machine shop that does a lot of head work and keep a pile.

    Remember. Switch as many as you can around to get proper clearance as these things are sooo expensive from the dealer.

    You could ad in the Wanted/for Sale pages the sizes needed. I know there's a few guys on here with quite a few.

    Good advice crux of the bisquet! For those that I’ll need to buy manuals can’t do it all I guess and I’ve only checked one Toyota website... There are 17 shims available according to manual with their designated number and thickness. I’ve bought stuff from www.OEMgenuineparts.com and have been happy with my purchases. Went there today and found the Shims but no 1-17 manual numbers or even thicknesses to go by. They do have a part number though which so far means little to me. Any idea how to decipher part number for these 17 little gems? Needing 5,7, 8 and 9’s. Maybe I’m using website wrong but looking to find a wormhole through time and space to a successful conclusion.

    Thank you Sirs!! I’m gonna roll the dice and go to my semi-local (twenty miles away) dealer for them. I’d prefer to have them by tomorrow but I’m sure they can get them in by Friday. I’m off Fridays because of the Virus effecting our company. They applied for Grant to keep us around for 8 more weeks. After that I’ll be without a job. Need to get truck running I may have to go contracting in order to keep food on table. That’s about 6 weeks from now. Anyway thanks for scoring me some Part Numbers that mean something! I’m just changing out exhaust valves because they are bad. The intake are within tolerance. But should I take some of my shims and try to get intakes in a better position? By that I mean it’s better to have a .007 or .008 than .006 or .009 Or am I wrong on my which is better thinking? Here is what I’ve taken measurement wise cam to shim, shim thickness and calculated from manual chart required shim!!! Intakes are good but could I, should I improve them? If anybody has time is my chart indicated shim correct?

    Thanks for all the help... just a little paranoid! I like having a second set of eyes confirming things.

    Ohh. Someone that enjoys math should check it.

    I think they're about 10 bux a piece or more. Looser is better. Noisy is ok.

    They almost always get tight because of head heat. Those shims don't wear unless starved of oil. Cam wearing will do worse than a loose tolerance. It's the valve seat getting smashed into the hot soft aluminum head.

    Someone once pointed out that in the factory Toyota could choose shims to the nearest 0.01mm but from the dealer you can only get 0.05mm between sizes, so the best you can do is shoot for the middle of the acceptable range.

    Ideally the average of the 2 intakes on each cylinder would be about the same so each cylinder is sucking in the same amount of air, but it probably doesn't matter once the valve is fully open. I mean I have no reason to think a slight variation in valve clearance between intake cylinders actually makes any difference in the amount of air sucked in. I kind of take the specs to mean anything within range is good enough. If Toyota thought it made a difference there'd be a smaller spec range.

    It's easy to go nuts thinking this out. That happened to me. In the end you just get them within spec and live with a slight variation between clearances. It shouldn't effect how the engine runs if they are all within spec.

    I agree, I just didn’t want to miss any opportunities to improve it. Thought I’d ask and kind of wondered if improved intake performance would reduce exhaust wear... because that cools cylinder to some degree.
    Oh and Avoid the math use the manuals chart. I bounced the math off of one of them and chart was correct. Just afraid that I might of looked at the number wrong or lost my place when doing them. I did get number blind a couple of times.

    Toyota went to a one piece bucket instead of bucket and shim. If you need to "reshim" you replace the whole bucket with the appropriate size. I'm not really too familiar with this. It's just from reading about it before.

    I'm not sure about the valve seats, or if what you read about was the bucket and shims.

    Me either... no better than my memory is I probably shouldn’t have mentioned it. I think that what you said is what they changed in 03.

    Yes, when you pull shims out of old heads you can get many more sizes. It's why we need a travelling kit of used shims.

    Every motorcycle forum has them. It's one of the big reasons for being on the forums, to have access to specialty tools.

    I’m going for the record of longest time it took to repair a Toyota... factor in I hate winter in (my) garage, finding useful information prior to doing job, gathering parts at bargain prices and additional tasks that come along that add to repair time. Ordered my valve shims 3 weeks ago because of price savings from ToyotaPartsDeal.com..... And just received them on Friday. Measure twice cut once updated into check math/chart three times and then order should’ve been my motto. Missed one of the ten shims by one number. I needed an 8 but ordered a 9 from next line down on chart. Anyway gonna get it on Tuesday locally.
    Not getting lazy but have a couple of questions.

    1) Do I really need to change those cam plugs or just RTV up where needed and if needed.

    2) Same question for half moons.

    3) Toyota RTV vs store bought RTV which should I use? Don’t currently have Toyota brand but could get some.

    4) Bigger question is that I would like to clean up throttle body and put some stuff on it but it made it look almost as bad in my opinion. How would you clean yours up? Was cleaning stuff up while waiting on shims.

    Sonics tray. Ha, we the same age bruddah.

    I reuse moons. they don't wear out. Black or grey RTV whichever is your flavor. Not to say Toyo's is bad but c'mon, they have no patent.

    This is the biggest reason to make a big kit. So no has a vehicle sitting around waiting on shims. I have a couple handfuls. A few of those and we could get one started.

    I got the toyota fipg. Its good stuff and feel like it sets harder than regular rtv.

    I only cleaned and re-glued stuff that I had to move. Other than I just left it if it wasn't leaking.

    I have no solutions for cleaning the aluminum other than polishing it and putting some sort of coating on it. Waaaay too much work for me.

    Helped Son and Daughter-in-law move into their first house on Friday... worked on various things including truck on Saturday. Truly thought I would finally get done on Sunday. Ran into a snag when it came time to torque Harmonic Balancer. My big torque wrench only went to 150’ lbs. So I went to Oreillys to rent one came home and that piece of junk was broke and wouldn’t lock. Went back down and got another one and it would rotate up but would lock. Their Torque wrenches make Harbor Freights look like Snap-On. Anyway got to find torque wrench that’ll do 217’ lbs. hopefully a friend will have one at work. I doubt I’d use one that big very often. Very close to being done and got exhaust shims all installed on Saturday. Cleaned valve covers and painted them prior and changed gaskets. New water pump, timing belt, and cam/crank seals. Various other new parts and painted some of the old ones. Thought I’d finally get done but didn’t make it.
