1FZ-FE - Cylinder Head Replacement

[Fj80oregon]

So it's a year later and I am finally getting around to this build.

I am using a new head, valves & springs. Reusing cams, buckets, shims, retainers &keepers.

Lapped the valves and checked for leaks. All good.

With regard to measuring valve clearance, does it make more sense to do this on my bench or with the head mounted to the block (on an engine stand)? I understand I can do it either way, but wondering what the rest of you all would do. Seems to me it would be less work to wait until the head is mounted to the block.

Do it on the bench

Does the new OEM head come with the valve seats and valve guides installled?

Valve clearance check on the bench makes sense if you want to get everything dialed in before install, but honestly I've always done it after mounting to the block on a stand — you're getting a more realistic measurement that way since the head is under its own weight and you've got it torqued down. Either works as long as you're patient with the shim selection.

One thing worth mentioning: if you're reusing the original buckets and shims, label absolutely everything before you start. I made the mistake once of mixing up shims across cylinders thinking I'd remember the order, and then spent twice as long sorting them back out. Little zip-lock bags with a Sharpie on each one. Takes five minutes and saves a lot of grief later.

Yes

I've got a few shims out of spec that I am going to swap out. I see some generic iterations of the Valve Tool SST (09248-55040) on ebay, etc. Anyone have experience with these cheapo tools? Any reason to track down the official Toyota SST instead?

Why put a generic link to ebay in your post when you're asking about a specific tool? How are we supposed to know what you're asking about?

The link was auto generated when I mentioned the site. I didn't link to the product to avoid promoting a fly by night ebay seller. Plus their links expire.

Here is a picture of the tool set. There are many identical sets for sale.

Why do you need a sst tool to replace the shims? Just pull the cam and swap in the correct shim. I have the Toyota tool and it works good takes some patience. I only purchased because I use it often on rebuilds but I would not buy one for a one time use. OTC also sells the tool.

I have 2 more 1FZs that I will be cracking open after this one. I was trying to avoid removing the cams and OTRAMM used a similar tool in his valve adjustment video.

Good deal, I would avoid generic brands just because of the precision involved, Toyota or OTC.

i bought one of those generic tools in the past but struggled with it.
I have found it much more precise and easier to remove the camshafts after measuring clearances 1st and then doing the calculation / shim swap etc.

I have used one of those tools and found that it didn't depress the bucket enough to get the shim out. I tack welded a few tacks and filed them smooth to get the extra distance needed.
