Excellent video once again y’all!! An entire hour showing literally everything you would need to know-see to do this job! Nobody is doing it like this! I don’t even have this engine, or most, but I still love to learn about Toyota -Lexus engines and other issues. It all can help me with my 21’ 4Runner TRD ORP if ever needed to do anything other than maintenance. Appreciate all the content. If you haven’t already, I’m sure we’d ALL love to see some tour videos of your older 4Runners and what you’ve done to them! Love seeing them in the background!! Great stuff brother appreciate all the time/effort to put these well informed detailed videos out there for us to use! God bless~

[@TimmyTheToolman]

Thanks for the compliment. You are right that nobody else is going to show this level of detail performing this job.. I truly believe it's what sets us apart from almost any other DIY Automotive Channel. We have a video walk-around of my 85 4runner. Check it out: kzbin.info/www/bejne/iXvCZ3xsoJuhmtEsi=RcUQ1LlWc-HPyvtD I haven't done a walk-around of my 98 4runner yet.

[@richardsauer599]

Another great video! I love to hear of Toyotas with an obscene amount of miles on them. Really, the maintenance you performed here was pretty routine. Especially for the high mileage. Happy holidays to you and Sean.

[@TimmyTheToolman]

Yeah, definitely routine maintenance for sure. I think doing a valve lash adjustments gets overlooked a lot though. A decent percentage of shops don't even want to do them because of how time intensive and tedious they are to do. It took me a long time to adjust 11 out of the 16 valves. But, keeping the valves in adjustment can prevent expensive repairs like having to pull the head off to replace valves that got a hole burnt into them.

[@benaldredge2671]

Great video guys. Tim, as always I appreciate your humor. Had me cracking up. Big difference in the way it sounded and idled before and after. Quieter and smooth idle.

[@fireyourrocketts]

Whoa! this is a great video; now my post will be long, probably the longest; I have a 2000 Toyota Tacoma, standard, 2RZ engine 4.2L; after a fuel pump replacement from a street mechanic he let me drive it with old fluids, I blew the head gasket, only drove like 25 miles but enough to blew it because the truck was parked for 5 years prior. after that its been parked for last 3 years but now I need it all the sudden ASAP because I have no vehicles; have a 2015 Chrysler Van which is half way engine swap due to hydro lock from my daughter but had to stop working on it after a work injury, then the only vehicle i had was my company van but they asked for it just yesterday as I am on indefinitely leave, so since yesterday no way to move. For the Tacoma I was going to do the whole engine, including pistons but that was a plan before I was hurt, now I need to act on it and start taking that head off to send it to the shop; i have mostly everything except few things I will replace while in there; I was going to do the clutch but decided will only do the head gasket; your video takes me half way there and you give lots of detail and info which is awesome. I have seen other youtuber one had to almost lose the whole engine to get to the head and I am hoping that is not the case with mine or i would be in trouble; I will remove/ probably replace the radiator, which I have, may replace the water pump. oil pump and maybe timing gear while I am there or leave it for the whole overhaul later on, don't know. this Tacoma has 209K miles and I own it from zero miles; will be 24 years with me this December so I may not even need to replace many of the parts I have for replacements. When the truck did not started again after the head gasket blown, the same mechanic came by and we did a compression test giving zero on cyl 1 and 3 and 180 on cyl 2 and 4. That was the least time it ran then have been for 3 years on the side of my house. It is a shame I am not done with the Chrysler because I do have a Max Jax Lift in my garage installed to work on the Chrysler but since I had to stop, car is on the lift and cant use it. I was planning to fix the Chrysler then the Tacoma but now in my condition makes sense to get the Tacoma going as the labor is way less intensive than to getting the whole engine out of it; may be running in couple weeks if I start today and I will right after this post. If you have ANY recommendations for me they will be very welcome. I have fixed a 2004 Toyota Corolla brought it from dead to almost factory condition after 2 failed street mechanics stunts; had no choice but become my own. Between you tube, the Haynes manual and sometimes me bugging the hell out of Toyota Techs, I am confident I can do it carefully. Cant leave my house until that car is running so it is critical. I subbed.

[@TimmyTheToolman]

@fireyourrocketts Man, that was a long read. I unfortunately don't have any experience removing the head on a 2RZ or 3RZ. What I do know is that those engines are prone to burning up valves. The valve clearance gets tight, and then they end up burning a hole in them. That is my theory for your low compression in those 2 cylinders. Have you considered buying an affordable used vehicle for the time being?

[@CopperHeadRoad-o4w]

Real helpful for getting to know this engine. Planning on replacing my PCV valve on my 01 Tacoma.

[@TimmyTheToolman]

I'm glad our video helped you know your engine better. Good luck with the PCV valve replacement.

[@howabouthetruth2157]

Whoever told you that the 2.7 liter 3RZ-FE engine "has a bigger bore/piston" vs the 2.4 liter 2RZ-FE engine, is incorrect. Both engines share the same bore/piston size of 3.74". The difference is: the 2RZ-FE has a shorter stroke at 3.39".......vs the 3RZ-FE which has a longer stroke of 3.74", making the 3RZ-FE a square engine........while the 2RZ-FE has the same bore of 3.74", but with the shorter stroke of 3.39", which makes it an over-squared engine. Think of the 3RZ-FE engine as "the stroker version of the 2RZ-FE engine". Because of the longer stroke, the 3RZ-FE is the only engine of the 2 that has a pair of counter-rotating balance shafts in the block, while the 2RZ-FE does not have the balance shafts. When replacing the timing chain, gears, and related components in the 3RZ, it is highly recommended to replace the chain & gears that drive the balance shafts, as well as the front balance shaft bearings, and the new parts for the balance shafts I just mentioned are quite costly. In higher mileage 3RZ engines, if the front balance shaft bearings are not eventually replaced, the old bearings can wear completely through, which then causes the balance shafts to rub/rotate directly against the bearing bores in the front of the block, and will render the engine block totally useless. ( There is NO way to re-machine these front balance shaft bearing bores in the block. The block is now junk. ) This is why many if not most 3RZ-FE owners remove the balance shafts & all related parts. When I had my 3RZ totally rebuilt, I had the balance shafts & all related components totally removed to totally alleviate this issue. Also: the balance shafts, gears, and chain cause a fair amount of parasitic loss to the power of the engine. Once removed, the engine has better throttle response. ( There's an oil galley on the front of the block that MUST be VERY CAREFULLY drilled, tapped, and plugged when removing the balance shafts permanently. The balance shaft bearings must also be rotated 180 degrees then re-installed, in order to block off those oil galleys, or better yet, buy the $100 balance shaft removal kit from LC Engineering that includes 2 new "dummy bearings" to replace the original balance shaft bearings, plus this kit has a really trick, custom oiling jet made by LC Engineering that will spray oil only on the timing chain & gear, so you're not wasting oil pressure by spraying oil where it is no longer needed. This kit has everything ya need to remove the balance shaft system. )

[@TimmyTheToolman]

Wow! Thanks for sharing all that information. My buddy Jordan recently talked to me about deleting the balance shafts in his 3RZ.

[@howabouthetruth2157]

You know I was thinking about your friend Jordan and his 3RZ, and that's why I decided to add all of that information about the dangers ( to a fine engine ) of extensive balance shaft bearing wear. Because when it's too late, IT'S TOO LATE!!! Seems like somebody could at least come up with a way of fixing the 3RZ block if the balance shaft scrubbed it's bearing bores, but evidently not. Timing chain, gears, guides, etc are reasonably priced for this engine ( LC Engineering sells the best kit in the industry ), but man, to buy the chain, gears, bearings, etc for the balance shafts is quite pricey!!! LC Engineering's kit for deleting the balance shafts comes with literally everything you need: the dummy bearings, a nifty bearing removal & installation tool, the correct drill bit, tap, and plumbing style threaded plug for plugging off the oil galley on the front of the block, a and of course the really cool custom oil jet I mentioned earlier, and they even provide 2 new special bolts for installing this oil jet. The only thing you supply is a drill, a T-handle wrench, and some loctite. LCE has a youtube channel, and a really good instructional video on how to perform this operation using their kit. This kit is so good ( for only $100 ), that I see other Toyota specialty websites selling it. And they even state that it's the very kit produced by LCE. Be VERY careful when drilling & tapping that front oil galley. ( It's the only one that needs this procedure. ) Use vaseline on the drill bit and tap, and go slow, while backing out often to collect the metal shavings. Ya don't want to get any of those metal shavings into the oil passages of the block. When the job is done, it's SO gratifying to know that you'll never have to worry about those pesky balance shaft bearings again ( let alone the costly replacement parts. ) I haven't noticed any real "added vibration" while driving. Even the rear & side view mirrors are steady as a rock while idling at a red light. Seat of the pants throttle response is much improved as well. I hate to see anyone lose such a precious engine over these damned balance shaft bearings. ( Ya leave the rear balance shafts bearings in the block, they are designed differently and pose no threat. Nor do they require any plugging of oil galleys. This is coming straight from the engineers & techs at LC Engineering. )@@TimmyTheToolman

[@lilant2219]

@ good to know I was reading the forums and a good amount of ppl broke these bolts so it had be wondering if it was a manufacture defect. Mine is the 2Rz model for a 95 2.4 Tacoma. This video should be pretty much the same thing correct ? Mine has a rubber groumet where the PCV valve goes in and guess what fell in when I took out my PCV valve last night ??? Yup the rubber groumet and I can’t fish it out so I’ll be doing yo valve cover gasket today lol 😂

[@TimmyTheToolman]

@@lilant2219 Yeah, it should be the same process for you.

[@lilant2219]

@@TimmyTheToolman APPRECIATE IT MAN Video gave me confidence to swap it out today. Would you recommend using a breaker bar or ratchet to reduce the risk of snapping those valve cover bolts ? Mine is the original valve seal and bolts

[@TimmyTheToolman]

@@lilant2219 Just use a short ratchet so you can feel how much force is needed. If you really have to apply a lot of force, then that's not good. The torque value is very light for these bolts. They should come out very easily with minimal force applied.

[@kenkaneki7273]

ChatGPT My spark plugs have been newly changed, and the valve cover gasket has also been replaced. After a long ride, there is a misfire, and the mechanic said two ignition coils are broken. However, when I tried to change them, I found a little oil in the spark plug and on the ignition coils. What should I do? Could it be that my ignition coils are not actually broken?

[@TimmyTheToolman]

That is a possibility. Just a little oil usually doesn't affect the coil packs though. It's usually when the tip is submerged in engine oil that it causes issues.

[@Mick-oi3wy]

See my other comment. Looks like the EGR has been deleted sometime in the past on this engine??? I see the 3 vacuum hose nipples on the intake plenum have been plugged off. ???????

[@TimmyTheToolman]

Maybe this engine never came with an EGR. I doubt the original owner of the truck deleted it, but maybe he did. The truck has been in California it's whole life and the smog laws here aren't exactly lenient.

[@howabouthetruth2157]

Is the owner the original owner? Also, seeing as California is the most strict about clean emissions, I would think that an EGR on any engine from this time period ( new engines with VVT don't require an EGR system ) would be the law there. ???????? @@TimmyTheToolman

I always enjoy your videos, Tim. I have a 1st gen Tundra 4X4 that needs new front axle shafts. Any chance you might be able to do that job in the future? Great video, Thanks for sharing.

[@TimmyTheToolman]

Hey Russ, it's great to know you enjoy our videos. We don't have a video for replacing CV axles on a 1st Gen Tundra, but the video we made 7 years ago replacing CV axles on a 3rd Gen 4runner would suffice. From my recent work on a 1st Gen Tundra doing a suspension upgrade to it, the steering knuckles look to be identical to the knuckles on a 3rd Gen 4runner or 1st Gen Tacoma. So you could use the video I linked to understand how to do it. Just disregard the whole rebooting and boot stretch mod part of it if you're not going to be rebooting your axles.

[@mandoky1647]

When you do coil packs and sparkplugs replace them all. Not one at a time. You're just setting yourself up for the same job multiple more times.

[@TimmyTheToolman]

Spark plugs are a wear item that should be replaced for engine maintenance. Coil packs are items that are only replaced when they fail. If you replace them "just because they are old," you're throwing money away. If the coil packs were an item that were hard to access, then your methodology would make some sense. OEM coil packs are expensive.
