Hello to anyone reading. Not sure how active this forum is but I'll post my build on here. I don't have Facebook or anywhere else to post it (Let me know if there is somewhere better).

The Story Begins

I've been looking for a camping vehicle. I'm sick of working on all my Chevy trucks/SUVs so I started looking elsewhere. That's when I came across the Sequoia. After looking at 9 different ones, I found her. 2 owner, not rusted out and in my price range (think cheap LOL). It's as plain as they come. 2006 Sequoia SR5 with no extra anything and 233,000 miles. Everything works with the exception of the rear wiper and window. I'll get to that eventually.

What I've done so far

Over the past 2 weeks I've been replacing/flushing/updating things. It started with the Front and Rear Diff fluid. Neither had been replaced by the second owner according to service records. Both got fresh new Amsoil fluid. The front was fairly easy, the rear on the other hand was not. I had a heck of a time getting the drain bolt out. With those completed I jumped up into the engine bay. That took some time but was finally acceptable after many hours and much elbow grease.

151103


Next up was the leaking Valve Cover Gaskets. I usually go with OEM everything but I was able to source FelPro Gaskets locally. After watching several YouTube videos I really thought it was going to be easy. Boy was I wrong.

The passenger side came off first. The bolts felt really loose, like almost finger tight. Once they were off I could look at everything...after I got the valve cover untangled. As soon as I tried to lift it off what is the first thing that happens??? Sand falls right on the cam face. :oops:

Guess I didn't get everything when I detailed the engine bay. I rinsed it off with oil and sucked up everything I could from the head. The passenger side cover had some old dark oil burned onto it, but nothing too crazy. Most of it wiped away with Brake Parts cleaner. I don't know that that's the proper thing to use, but it's what I had.

Onto the Driver side Valve Cover. This side was crazy dirty. I haven't figured out the oiling on these or if one side may have been worked on before. Are the Driver side more prone to gunk? Further from the oil pump maybe? This is my first Toyota so I'm still learning.

Once I had both covers on the bench I started in on the spark plug gaskets/seals. HOLY SH*T!!! Not a single one of them would budge. That was after bending all the small tabs up. At first I was being nice and trying to gently pry at them. Once the middle of each seal broke I started getting frustrated. Then out came the BFH 馃敤 and screwdriver. Once I figured out the original seals had a metal lip around the outside edge, I gave them a whack with the screwdriver/hammer combo. Once I had a small lip to pry on, they came right out.

Then came the reinstall. Trying to get them back in with RTV on the corners was a PITA. It was like a very bad game of Operation Once I got them back on I put the new washers/seals on the bolts and finger tightened them. After letting them sit for an hour I torqued them down to what I thought was 54in/lbs. All in all this process ended up taking me 6.5hrs and 4 beers. New plugs were also installed at this time. I used Denso SK20R11 Iridium plugs.

Tomorrow morning when I get out of work I'm picking up a little torque wrench to verify them.

Next on the list
The timing belt and water pump haven't been done since 90k miles. The dealer wants $1200 just for the parts and 4 hrs labor at $110 per hour. From what I can tell you can get the OEM parts on several different sites for around $400. I'm still double checking all the part numbers as I'll be doing the pulleys and cam seals also(if they can be done with the cams in). Anyone know where the parts list can be found for the updated engine type?

I'll also be doing the center diff and trans fluid. The PO had no idea you could change the trans fluid so that has never been touched. I'll be using the 3.2 quart at a time flush with OEM Toyota fluid. After that I may as well do the Power Steering fluid the same way.

When all that is done I'll start under the truck (do we call these trucks???) The frame looks great for being from Michigan. I figure I'll coat it all with some RP-342 Black Cosmoline to keep it nice. Once everything mechanical is done, I can start on the fun stuff. Looking at an OME or Dobinson mild lift kit, New UCA and LCA, some wheels and tires, upgraded stereo with GPS/XM/Bluetooth and recovery supplies. If I get any interest on here I'll keep posting my build. If not, I'll try to find somewhere active to post it.

Thanks for checking out my build so far. It's going to be a slow one, but should be ready for camping in the spring. Any advice is greatly appreciated!!!

You made a great choice! For the money, these trucks (yes, trucks!) are a much better value than anything GM. Build quality is solid and in general they are simple to work on. They do have a few quirks and as with anything, projects can easily become more complicated. The timing belt/water pump is not too bad. Lots of great resources and step-by-step instructions on here and on YouTube. Toyota put these 4.7s in 5 or 6 vehicles and the directions are all the same for the timing belt, so you can look at resources for Tundras, etc.

There are a lot of options for mild lifts. Check out firstgenoffroad. I think they sell some of the lift items and accessories but if you search them on YouTube you'll find a bunch of great videos about Sequoias.

post away. i'm trying to get motivated to do something similar with my 02 which is now retired from being the family truckster so I can do whatever I want to it. but mine is all rusted out so it's risky to invest much money.

Good luck on your build up! I just got back from a 700 mile trip over the holidays, and with 300k on the odo, it just proves that if you take care of these trucks, they take care of you.

Thanks for the replies!!! I've been looking at the 1stgenoffroad website and have watched all his videos @LookingUp. @jbarnett2501 do you have a thread on here? I'd be interested to follow along. @SilverSasquatch I'm really digging the name. :D We do some camping off the beaten path and always got an eye out for the squatch. I'll have to get some pics when my stickers show up. Should put a smile on some faces.

I got a small torque wrench today but didn't get a chance to finish up torquing the valve covers. Probably get to it in the morning. I'm still trying to get back on my 3rd shift schedule after the holidays. Have any of you done the stock airbox mod? Is it worth doing? I've already got the box off and have enough random stuff laying around to complete it.

I don't have a build thread as I'm 100% stock at the moment. All my posts have been related to just keeping mine on the road. Need to replace my entire rusted exhaust ($) including cats and leaking manifolds and a lift ($) would make me want to get new wheels and tires ($$). So for the moment I'm just trying to decide if it's worth the risk to upgrade a bunch of parts only to have something come along in 6 months that makes me scrap the vehicle. Reading about other people's projects makes me think I can pull it off too though so keep posting.

I need to change exhaust system and valve cover gaskets. check out the steering, feels loose. but yeah, people ask, 'you still driving that truck?' and I just smile, been a great truck. looking at sequoias now. like to get a 14 with 1794 package.

i went with the aisin kit which i always read was the maker of the oem parts. was much less expensive at like ~160 for everything including the water pump, tensioner, idler,etc. lots of recommendations for the aisin kit around on the forum. worked fine for me but i did have the belt jump a tooth and cause all kinds of timing problems. even when i paid a shop to do it (don't know what parts they used), it jumped a tooth in 30k miles. had to get the crank holder tool to remove the crank bolt as my compressor or impact wrench wasn't up to the job.

I'll have to have all Toyota OEM stuff. I'm in the middle of Chevy country and most Mechanics in my area won't even look at it. So I'm taking it to the dealership for them to do. They quoted me $1200 for parts and 4hrs labor at $110/hr. I figured if I could find OEM parts for half that cost, it would be worth it.

How did you know it jumped a tooth @jbarnett2501 ? Was any internal damage done?

I don't want to hijack your build thread with my old story. i put up a thread somewhere describing my flashing cel which after checking everything else turned out to be a timing problem caused by the crank jumping a tooth on the belt. To check the timing, you put the crank at the 0 mark and pry the upper timing covers back far enough to see the marks on the cams. They should line up with the marks on the heads but my cams were both off by a tooth. Truck will run but misfires like hell. No damage as far as I know.

A present came in the mail today. All my new parts are here!!! Full OEM Water Pump Kit. I've been doing some poking around and found that this truck has never had the timing belt done. I thought I saw it was done at 90k, but I can't find anything to back that up. Doesn't show up on CarFax or any receipts he kept (he saved every receipt).

Now for the hard part. Do I take it to the dealership or do it myself? I don't really need the truck until spring so time isn't a concern. Guess we'll find out shortly. Time for some Parts Porn!

Watch some youtube videos. It is not extremely complicated. There are a few tricky spots, though. It might be worth peace of mind to get someone to do it!

I'm glad I did mine myself. You get to know your vehicle when you take it apart. My belt change only cost me the $160 for the kit and <$30 for generic pink coolant. My local major Honda-Toyota dealer f-ed up a diagnosis/repair of a bad wheel bearing in my wife's CR-V a while back and I ended up on the hook for $800 worth of differential parts that weren't bad. Since then I don't trust them and would rather f-up the repair myself than pay someone pro-money to f it up for me. My vehicles are at the very bottom end of their valuation so if I blew it up it's not a catastrophic financial loss though. The only special tool I had to buy was the $60 harmonic balancer holder to remove the crank bolt. I can borrow everything else from the local auto parts store like a puller etc. I already had a long breaker bar and a 3 foot cheater to bust the crank bolt loose. The youtube videos and diys on this site help for sure.

I also DIY'd with the Aisin kit. Only issue I had was routing the wire for the cam sensor. Didn't route the wire correctly and it got destroyed by the belt. That won't happen again!

I do think that there are some differences for OP since he has a VVTi engine in his 06. Does he have to remove the cams? Or perhaps that is only if he's replacing the cam seals?

I took mine to the dealer to have the timing belt done, and the tech forgot to check this exact issue. Left me stranded on a road trip. Cutting the cam sensor will kill the engine. So tuck it back where it belongs to avoid a headache!

Mine started for a second then immediately stalled out and threw a bunch of codes. I guess I had left the wire directly on the timing belt. I thought I had messed up the timing or something more serious. It was a tough few hours until I found the bad wire. Luckily, I hadn't torn it all the way back down yet...only about halfway. Advanced Auto had one in stock at one of their larger stores nearby, so I really only lost an afternoon of time.

Thanks for the heads up on the Cam Sensor you guys! I'm still on the fence about doing it myself. Not that it would be difficult, it's cold here in MI and my time has been limited lately. Trying to sell 2 houses and buy another. I'm also not sure I trust the dealership to do it. Wish I could find a mechanic around here that worked on something other than Chevy's. My old mechanic told me to never bring him another one of my Subarus. LOL. Anyone know of a good Toyota mechanic in Michigan??? I know it's a long shot but I figured why not.
