I started working on these in a Toyota dealership in 1977 always do them running I adjusted 1000s and I found a big difference between stationary and running usually too tight.The lifters rotate as the engine runs a little loose no dramas a bit noisy too tight they will burn valves drop the idle speed down when adjusting it makes it easier.Check the back manifold bolts they come loose and fall out sucking air and burning valves.I did a lot of valve grinds on these "Burnt Valves".
I was doing this adjustment on my 79 fj40 and realized that the previous owner damaged two of the adjustment screws and I'm really struggling to find the reference for this. do you by any chance know what the diameter and thread pitch is for this screws? or if a screw for a different engine works on this or maybe they are standard? great video, thanks for the information!
To answer your questions: 1) I do not know the diameter and thread pitch, but you can measure these with two simple tools. Use a dial caliper for the diameter and a (metric) thread pitch gauge. I wouldn't be surprised if these are non-standard. 2) I don't know how different the heads are across the various F engines. Someone on IH8MUD.com likely knows the answer. I think a better idea is to find exact replacements. There's a good chance you can buy new replacements from online shops like toyotapartsdeal.com. A salvage yard that specializes in Land Cruisers like classiccruisers.com will be able to sell you used replacements. Someone on IH8MUD.com may have extras they can sell or donate to you. Because V8 swaps are common, there are lots of used F engines out there.
Hi form Australia Nice video on doing the valves Just a quick question im trying to tune a 350 holley on a 3f engine what size jets and power valve did you use?
Thanks. I hear there are lots of FJs down under. I don't have the jet information handy and I don't know that it would help you much because it was re-jetted (leaner) for altitude. I'm not a carb expert by any means, but if your 3f is more or less stock and you're at sea level, stock jets should work pretty well.
@@mikerestoresanfj4069 thanks for the reply Its a bit of an odd one its a fj75 ute with 130 litre lpg gas tanks plus the 80 litre fuel tank. but at the moment i got 61 jets and a 6.5 power valve at sea level it revs great at idle but not in gear i think the fuel pump might going bad does your factory one supply enough pressure
There isn't a clearance spec for a cold engine because it's actually not very important. As the engine heats up, metal expands and clearances get smaller. While larger clearances in a cold engine result in reduced performance, it doesn't last long. You want best performance when the engine is up to temp. It's pretty much normal for a spark plug to turn brown in a few days. You can learn more about how to read spark plugs here: www.championautoparts.com/Parts-Matter/automotive-repair-and-maintenance/how-to-read-spark-plugs.html Is your engine running badly when it's cold?
Timing marks can be found on the flywheel. These can be seen through an inspection window on the clutch housing (near the starter). There is a small ball at 7 degrees before TDC and a line at TDC. It's a good idea to mark these with some paint to make the easier to see. Here's a link to a CZcams video: czcams.com/video/dfUNxDfxam8/video.html
@@mikerestoresanfj4069 thanks for the reply. Is this port present on fj60 models? I don't plainly see mine. Perhaps it's buried under 35 years for oil and grime
@@lastfirst5790 I don't know much about the FJ60, but I think it used the same 2F engine as the FJ40. If so, there should be a port under the grime. There might be a cover on newer engines.

Good tips, thanks
Thanks Mike working my FJ40 1976 atm so appreciate your journey
Thanks for the kind words. Hope you get yours up and running soon. Would love to see some pictures.
Love this! Thanks... I have the same issue and Im going to try to adjust my valves tomorrow!
Good luck!
awesome video👍
Thanks 🙏
Should the engine be warm at these clearance specs? Great video!
Yes get engine to operating temperature and adjust
Yes, it should be at normal temp
Good video.
Thanks!
So you bump engine over for each set of valves to their high point then set gap and tighten?
Ive been hearing a ticking in my head so I believe the valves need adjusting on my 67 fj40
It's the low point. You need the rocker arm to be at it's loosest point. You should be able to rock it back and forth and feel a little slack.
A little ticking is normal, especially when the engine is cold. The adjustments should be done on a hot engine.

Also do you have any gas pedal parts or linkages for a 67 fj40? Mine has been rigged and I need these parts.
I don't have any gas pedal parts. If you can find a salvage yard that specializes in Toyotas or FJ40's, they'll probably find something for you.
Wats the recommended crearance for 2f when cold, I have a problem with plugs, everytime I replace they brow within days.

Is your engine running badly when it's cold?
what is the valve clearance for fj62 intake nd exhaust
I don't know offhand, but I'm sure the guys on ih8mud.com will.
Is that a Weber carb?
Sharp eyes, it is. Swapping for a Weber was a popular upgrade back in the day.
How do you find TDC?
Timing marks can be found on the flywheel. These can be seen through an inspection window on the clutch housing (near the starter). There is a small ball at 7 degrees before TDC and a line at TDC. It's a good idea to mark these with some paint to make the easier to see.
