UPDATE: Some of you noticed I did not put a service pin in the cam, weird part is even without the service pin the cam did not spring back. (I thought this was strsnge but did not mention it in the video). So I tried swapping the cams from the other 3.4, and using the service pin (these cams did try and spring back). So now with the cams swapped and now under tension it seems to be fixed!
Ok all may not be lost. I think you should check out the cam and make sure the split cam didnt relax. It has a spring in it and can move 1 tooth. That is why toyota put a treaded hole on the gear to keep that from happening. If it does relax a tooth it wont keep the cams tensioned to each other. Which causes the diesel sounds.
I replaced the valve cover gaskets, plugs and wires on mine and it started doing the same thing. Tick on the drivers side only after it warms up. I still haven't figured out what it is, but it runs fine.
Stacey and Matt from Toyota World Runners seem like amazing people. They drove that truck from Canada all the way down to the end of the Pan-American highway. It has the 3.4 L 5-speed. I'm pulling for you. Thank you for sharing and for being a down-to-earth cool dude.
That clacking could just be the oil brand you used my 4.7L made that clacking noise when i used the o'reilly's oil noise went away when i used Valvoline and yes both were 5w-30
Stick with the 3.4 for now. TDI swaps are cool, but very time consuming since about the only off the shelf part is the bellhousing adapter, you'll have to fabricate everything else yourself to mate the engine to the vehicle. I got the TDI into my Ranger with mounts and accessory drive brackets, but still have to mess with all the plumbing and electrical.
@PowerToolFun Could be. But strange part is they didnt seperate without the bolt in, stayed aligned. and its that side that is making noise. I did not realize that was even a thing until I did the other side and they seperated 🤣
it might be worth measuring valve clearance that way you can get an idea if it's related to the noise. Measuring them isn't difficult however from what I understand adjusting them can be a pain. If valve clearance is in spec then you could rule that out. I recently did this on my 3rz tacoma while chasing a misfire issue and was able to rule it out as they were in spec.
@@DirtGarage You just need feeler gauges to stick in between the cam lobes and the valve. Then add or subtract shims to the buckets to be in spec according to the feeler gauges.
Head bolt torque on these is 25ft-lbs plus 90 deg, plus another 90 deg. I hope you just didn't show the last step and don't need to tear it all apart again to fix it
I can never find a 3.4 that nots $800+ in my area. Not even one that needs rebuilt. Salvage yard rarely gets 3.4s and thats still $500 for it. Hopefully I'll find one i can rebuild soon to get my 91 going again.

yay - good find. gotta love youtube community!

That is likely it. When I pulled the cam out I forgot the service bolt snd it did not spread.
Check the valve lash after it’s warmed up.
I second this as a snowcat mechanic this is what id check very first. Hmu if you need another 3.4 i have one in my yard north of kaslo
Dark under the valve cover isnt good..i have over 500k km on mines and its golden brown..zero issues and had it for over 20 years. Love this motor
Yay! They were able to get Sunday back. That’s awesome.
I been waiting to see if Sunday made it through customs. Looks like we will be seeing a new video soon. Seen first on Dirt Garage. Cool.
Haha hopefully I didn't spoil anything for them!
you should put one of your 3.4 heads on it. Id bet when they put the cams back on loose stuff didnt get back in the exact order on that side
Napa was able to get me a koyo throw out bearing in a few hours if you still need one, was really responsibly priced too!
The new one actually came from Napa!
Great video looks so much more enjoyable to work on than the subi!
Thanks! It really isn't a terrible motor to work on. And luckily head gaskets are not a frequent failure on these.

grasshopper on the passenger door wanted a yota ride ! 😂
buddy needs to do a tdi swap walkthrough and how to on his 4runner

@@abpsd73 I dont mind the fab stuff
@@DirtGarage Me too. Which is why it's getting Toy axles and e-lockers. 🤣
@abpsd73 Nothing wrong with Toy axles
Super cool video! Your visitors are cool, too! I enjoy content from both of your channels.
Awesome! Thank you!
Some times we win some times we lose,here’s wishing you the best!
I think it is lacking oil pressure when hot.
Check for failiure the pressure relieve valve
Could be cam gear due to not having the service bolt installed before removal?
@PowerToolFun Could be. But strange part is they didnt seperate without the bolt in, stayed aligned. and its that side that is making noise. I did not realize that was even a thing until I did the other side and they seperated 🤣
My exact thoughts exactly.

Just a quick question were you supposed to do a 90°?arc from the video? Looks like from the video you only did a 45° arc.
Valve adjustment is easy. Just watch Timmy The Tool Man.
I wouldn't say easy. I mostly just don't have the tooling to check clearances.

@devondrayton4006 I know how its done 🤣
Whoa whoa whoa! I thought you always have to replace the head bolts!….
@MonkeyBrainSushi Nope. The instructions right from Toyota only says to replace if damaged
I'd love to see you tackle a TDI swap
Me too
That's a new one for me ... reusing head bolts lol
@@briggs1337 instructions right from Toyota says to re use
Bro I'm sorry you didn't have a good engine. I only have a power steering pump and a steering wheel. Glad you keep watching the future videos though
I appreciate it
Head bolt torque on these is 25ft-lbs plus 90 deg, plus another 90 deg. I hope you just didn't show the last step and don't need to tear it all apart again to fix it
If the heads are good on the motor you pulled out then try swapping them to this motor
Hell ya brother
I was gonna suggest you meet up with twr, i was surprised lol
Haha we have been in contact for years. Glad we finally met up!
@@DirtGarage hope to see some wheeling content!
My 03 Tacoma has 300,000 miles on the 3.4, never a mechanical failure.
@@michaelsedway9703 Exactly, usually they are fantastic!
my supercharged 3.4 is just about to hit 300'000 miles!
I just hit 325,000 miles on my 02 Taco 3.4.
I can never find a 3.4 that nots $800+ in my area. Not even one that needs rebuilt. Salvage yard rarely gets 3.4s and thats still $500 for it. Hopefully I'll find one i can rebuild soon to get my 91 going again.
They can still be found for pretty reasonable prices here luckily!
@DirtGarage toyota tax down here is pretty high. Found a short block with heads though. May get it to rebuild.
Lifters ? Roller followers ?
So close, I’m surprised you didn’t look at the cylinder walls & compression rings
Said by a non-mechanic (maybe you can some other way)
@nemesis851_ I did, looked good. Obviously didnt take it far enough apart to pull crank and pistons out to thoroughly check
Stockpile your Zzzzz’s
About to be having them on Backorder
My 5vZs? Or 1uZs? Maybe 3rZs? Hahaha, just kidding.
@@DirtGarage sleeping 💤 👩🍼👶👨🍼
Well I wish you, Sam, and the incoming, a HEALTHY delivery this/next week'ish (anytime now infact)
Hope you stockpiled them ZZZzzzz's
