Dude! Thank god there are people like you that dont take 35 minutes to show you this job. Excellent!

[@Kingcustomz]

hahaha youre very welcome, Im glad this helped

[@billstratman4230]

Appreciate the hard work that went into this extremely well-done video. Succinct and right-on with the info. I have done this job before, but needed a reminder and was happy to have found this. Thanks for the links as well. Great video.

[@Kingcustomz]

You’re very welcome

Thank you for watching and I appreciate the awesome comment

Dude.....this has to be the greatest how to video i think ive seen in a long time. No bs chit chat. No you can also do it this way bs. Just straight here ya go. And heres how. You are the man!!! And i will be using this vid to do exactly this to my highlander soon

[@Kingcustomz]

Thank you brother. I appreciate that. It took a while to film this 😂😂😂

[@cyeszin2818]

@@Kingcustomz oh dude I bet it did. But from one guy to another you have made my mechanical day with this find 😂

[@Kingcustomz]

@cyeszin2818 I am happy I made your day with this video. 😁😁😁

[@mountainbiker4450]

Nice video. My front gasket is leaking but my rear doesn't appear to be leaking. Since I have to remove everything to change the spark plugs, which also need to be done, should I also change the rear gasket or leave well enough alone?

[@Kingcustomz]

yes definitely replace the rear as well. you're already in there so do it. because how bad would it be if you reinstalled everything and then two weeks later the rear goes bad/.

[@mountainbiker4450]

@@Kingcustomz Thanks! I carefully watched your video again and had several questions that might help others too. (1) I need to buy some tools. You mentioned a e-torx for the coil pack and intake manifold studs. What size is that? Or perhaps I know the size, I can just buy a set depending on cost (2) For the throttle body, once off, I assume I should spray BOTH sides of it with throttle body cleaner? (3) Where can I find the torque values for the intake manifold fasteners and throttle body? (4) Also, it seems the rear valve cover gasket is very slanted. How did you access the rear bolts for removal and reinstall? (5) have you ever tried the OEM gaskets and spark plug tube gaskets? How do they compare with the Felpro kit you used?

Amazing video. Same on the 3.3 06 highlander?

[@Kingcustomz]

Yes sir

[@Kingcustomz]

And thank you 😊

[@TotalTechAutomotive]

How much do y’all charge for this repair parts and labor? Just curious from mechanic to mechanic

[@Kingcustomz]

I have to double check the exact figure but I want to say around 7 something

[@MrSupertim996]

You flew through the back bolt passenger side of rear valve cover and sliding the valve cover under the harness.. that’s what’s a pain in the a$$ for me

[@Kingcustomz]

Sorry man lol. It’s harder to film those angle

[@barcarfleites5289]

My 2003 highlander is disappearing about 1qt by day!! It does seem to be very wet around the valve cover, i will do this job tomorrow!! Any other parts that i might look into that could be making this car disappear so much oil? It does have white smoke so im guessing is burning some and leaking the rest

[@Kingcustomz]

Fix the obvious leaks and see how it runs from there. Make sure to also replace the pcv too. If it’s still consuming oil, check to see if your pistons have good compression

[@barcarfleites5289]

@@Kingcustomz hey! I fixed the oil leak by changing the valve cover gasket and pcv valve….now the car has trouble going over 55m-60mph while flooring it 🥲i put everything back the right way idk what i did wrong…any advice?

[@gdbox2123]

Can someone tell me what sensor is on the vacuum rail at 1:29. I tried taking it off and it completely shattered into pieces . …. 😂

[@Kingcustomz]

oh jeez 😂 one of the sensor is a vaccum switching valve

[@brenttownsend2554]

I miss my 81' Prelude.......😫

[@Kingcustomz]

get it back lol

[@jamesfarmer2748]

great video without taking forever. only thing different i would do is use a large impact socket to drive in those tube seals into the valve cover. i used a large one to drive them in on my 3.4 tacoma engine. very similar to this 3.3

[@Kingcustomz]

thank you, and okay good to know for next time

[@garynair5143]

Great job, well put together video. Rear valve covers are generally a pain, due to rear bolt access and clearances getting to them I change the rear coils and plugs w/o removing the valve cover. Removing PCV hose to get easier access to Cyl #1 on the left and once the center cruise control bracket is set out of the way, the central open cavity allows access to the middle Cyl #3 (hardest one). Test coil packs with a cheap < $20 inline coil pack tester with a clear tester window to view the spark.

[@Kingcustomz]

thank you for the positive comment as well as the information. i should get one of those

[@carlosamorin7989]

Hi, @1:35 you use a female e-torx socket to remove the wire harness that fastens to the front valve cover. Mine is broken. Do you happen to know the Part No. please?

[@Kingcustomz]

I do not know the part number, sorry

[@Christinme03]

Dude what a great video. Well done! Straight to the point and no bs. 👍 can you explain the what silicone you used and how much? What is the purpose of the red silicone?

[@Kingcustomz]

The red silicone is a high temp gasket silicone. The reason I used this was because the valve cover gasket would fall off and misalign itself. The gasket was tacky and helped me keep the gasket in place while I locked it down. Very little was used and it cost like 8 buxks

[@johnmcdonald2210]

Great video. Thank you. Where do you put the silicone on the rear valve cover.

[@Kingcustomz]

yeah i put it to basically hold the valve cover gasket in place from falling off

[@prtmeister9680]

Thank you. This is an excellent video...straight to the point and no steps left out... well, just top off the coolant, but let's not nitpick. Plus you provide all the part numbers. The Nut that works on Toyota's couldn't do it better. Time-wise, is this a 4-6 hour job? My '06 Highlander is leak city due to 355K miles and is long overdue for a valve cover gasket replacement.

[@Kingcustomz]

Hahah honestly barely any coolant spilled. But yes top off. And hm I’d say 4 hour job. The back cover is a pain

[@Dkftw23]

@@Kingcustomz Thanks for the brief and to the point video! I'm curious to get your opinion on a couple things. I'm looking to do this due to a P0420 code. Others are suggesting changing timing/accessory belt(s), water pump, flushing/replacing radiator fluid and thermostat +gasket. Curious to hear your thoughts on needing to do all that or waiting. Driving an 05 with 176k on it, bought it with ~174k and there's spotty maintenance records that seem to indicate nothing more than oil and tire changes have been done. I want to clear the code then also tune/maintain it for its age/mileage. Any comments are appreciated. Thanks again

[@richardhaen]

Very good video, I sure do thank u for the information on doing this. So many videos I have watched never tell u want the torque settings r the the valve cover, I just started to replace mine on my 2006 Toyota Highlander got 433250 on it now the gasket was broke in 2 places. Thank u

[@H-sgracesavedme1711]

[@Kingcustomz]

about three hours if you take your time

[@Joel4JC]

What type of silicone did you use?My auto parts store didn’t have a red silicone. Just curious. Great video by the way, thanks.

[@Kingcustomz]

i used high temp gasket maker silicone. regular silicone is fine
