Awesome job! Great video!! I'm considering replacing my spark plugs very soon. Now I'm thinking of doing the valve cover gasket because they have never been done before. 1777,800 miles on my 007 IS350. I'm a big believer in doing maintenance before it needs to be done only because it gives me pice of mind knowing that it's been done!! Thank you. Jeff Grant Mooresville NC USA

[@HelpingHandAutoRepair]

Lol yes V6 FWD or RWD setups are just irritating on these Toyotas. Simply because you have to take the intake manifold off. If the intake manifolds were designed like some other car manufacturers (like Mercedes for instance) then you don’t need to take the manifold off at all. They are very easy to do.

[@nathangoodman603]

@@HelpingHandAutoRepair exactly! My 5vz is easy for the passenger side because you dont have to take off the intake but the driver side requires both upper and lower intake plenums and the throttle body and all vacuum lines and you still fight the wiring harness like the 2gr.

[@MrUnknown747]

My cylinder 6 started misfiring ( same engine) and pulled the plug out and it was covered with oil. Is the spark plug tube seal leaking??

[@HelpingHandAutoRepair]

Ponyboy Yes. Unfortunately you need to pull off the valve cover to replace that seal. Might as well get the valve cover set and just replace both sides as I show you in this video.

[@MrUnknown747]

Thank you for the quick response!!! I figured that’d be the issue but wanted to make sure 100% thats what it is. Im uploading a video soon showing the plugs. Do check it out and confirm kzbin.info/www/bejne/kJvKgJV-i5iaers The Gasket kit I'm getting is below. Please confirm that aswell www.thewrenchmonkey.ca/products/auto-parts/fel-pro/vs50690r/

[@HelpingHandAutoRepair]

Ponyboy by your video I am not convinced that you have bad tube seals. The coil actually looks pretty dry. The oil on the threads of the spark plug appears to be ok. As you see the tip of the plug appears to be in ok shape. The coil looks dry and just dirty. It would be wise to read the codes (if you have a CEL on) and then you can try and pull just those coil packs and inspect them for lots of oil on the outside of the coil pack boot as well as oil in the inside of the boot. The valve cover set you have selected looks fine.

[@HelpingHandAutoRepair]

Ponyboy I would first clean off the threads of the plug with brake cleaner real good and then reinstall the plug and make sure you torque it down completely and make sure that it is completely seated. Then inspect the bottom of the coil boot (the spring inside should be dry) for excessive WET oil. If it is ok reinstall the coil pack. If the problem still persists on cylinder 6 then take that coil and swap it to the other side of the motor (ie the other head) and install it and see if the misfire follows that coil. If it does then you have a bad coilpack. If it doesn’t follow and stays on #6 then get back to Me.

[@MrUnknown747]

Thank you again. I will follow your steps and re-torque the plugs. The oil on the coil was minimal so it didn't show on the video properly. However, if you see the ends of boot between 0:30 - 0:35 you can see the ends of coil shiny. But there was oil on the coil 100%. Thanks again! I'll get back to you after performing your suggestions.

Chain is a big job. Everything needs to come off the front of the motor. Valve covers need to come off too.

[@KG-fx6nz]

How did you take the valve cover off if it’s after taking all the bolts off? What did you use to get it to come up and off the cylinder head ?

Great video man, nice and clean video. Would you mind sharing the list of Tools especially the one you used at the back near the high pressure fuel pump. thanks

[@HelpingHandAutoRepair]

sunny ponappa badalera Hello, honestly I couldn’t remember every single tool I used in the video. I will say that you need a set of metric 3/8” sockets with a 3 and 6 inch wobble extension. The high pressure pump is held on by two 12mm nuts that can be accessed very easy from the top. As well as the metal pipe that heads towards the back of the motor. It is held on by two 10mm bolts that should be able to be accessed pretty easilyz

[@johnalan6067]

Any idea what the torque spec is for the two nuts holding fuel pump?

Since somebody today might be wondering according to the Factory Service Manual it's 18 ft-lbs for the fuel pump and 7 ft-lbs for the flange holding that fuel line in.

[@irishuwould5185]

Can you tell me where the camshaft position sensor circuit A bank 1 is please

[@HelpingHandAutoRepair]

Bank 1 will be passenger side if you have the 3gr engine. Circuit A is Intake sensor. So if you are looking at the engine, in the front of the engine on the top of the valve cover on the passenger side cylinder head. There should be two sensors. One is for the exhaust cam, one is for the Intake cam. The sensor closest to the center of the engine will be the one.

[@irishuwould5185]

JustJay 0312 well you need to replace the crank sensor as well. I believe that is near the ac compressor on the driver side of the engine on the bottom or near the bottom of the engine. I don’t remember if you need to remove the ac compressor or not to get to it.

Marshall Kendo I can only assume the IS engine bay is slightly smaller than the GS I am working on in this video. If there is a way to detach the coolant lines via a bracket that would be able to give you more wiggle room, that would be the best way. You do need to loosen and remove the 10mm fasteners I mentioned in the video on the back of the motor and that little rubber hose I also mentioned. Worse case is you will need to disconnect the coolant lines that run on top of the it. I couldn’t imagine Lexus making it this difficult for IS owners but you never know.

Hi, Thanks for the vblog. To replace the valve gasket ,it's a must using RTV silicon gasket maker together with the oem valve gasket?

[@HelpingHandAutoRepair]

It’s not necessarily needed unless you feel like making a judgment call. I didn’t use any and there isn’t a single leak.

Hammer and a flat head or chisel will crack the seal and then you can pick it out. This happens all the time and they can suck to get out.

@@HelpingHandAutoRepair Thanks! Thats what I ended up doing. Was worried Id damage the valve cover. but it was fine.

In the middle of doing my 06 is350 right now. I unbolted everything on the driver's side valve cover but it's still stuck. Any advice on lifting it or loosening the gasket?

[@HelpingHandAutoRepair]

double and triple check there isn't a bolt still holding it down. Also if you followed the video completely, maybe you missed a bolt or bracket by chance. Sometimes they are stuck pretty good and you can get a small flat head screw driver to persuade the valve cover to come up and off. You have to be careful you don't gouge the aluminum head sealing surface.

Helping Hand Auto Repair do you know if they break or crack after time? since it’s right on top of the engine which emits a lot of heat I’d imagine they would heed to be repacked after a while

[@HelpingHandAutoRepair]

Raftika Maybe after a very long time. I have personally never seen one of these break. I have seen other plastic manifolds crack after over 200k mileage.

[@raftika1]

Helping Hand Auto Repair okay thank you for the quick response! I really want to get one of these in the near future but want to make sure I make the best choice

[@HelpingHandAutoRepair]

Raftika as far as the car? These are great cars! I do run a car dealership and these are cars I am always looking to purchase. Any of the Lexus IS cars are fairly reliable. I’d watch out for the 2005-06 models. They aren’t 100% bad at all but with higher mileage (200k plus) the transmissions can have a higher chance to fail. This is mostly due to neglect from the previous owners by not changing the transmission fluid in a timely manner. It still wouldn’t stop me from buying one but just check it carefully or have a pre purchase inspection done before buying one used.

[@marcomelo8576]

Could anyone please tell me how to put back the driver side banjo bolt back in the hole with that stupid A/C line in the way taking all the room? Do I need to remove that A/C line so I can have more room to get that banjo bolt back in place? ANYONE???

Your videos are a great help and they are very easy to follow along. It's awesome that you are wiling to help people like this! I also have a question regarding this procedure. Along with replacing the spark plug tube seals do you recommend replacing any other seals while having the covers off? Reading the forums, where I actually found your video, I ran across people saying that there is o rings in the valve cover for oil passages to the camshaft. Could you clear that up for me please? I looked at the parts diagrams on the dealer sites and such but I only found CAMSHAFT BEARING CAP OIL HOLE GASKET, could this be what it is meant? I also ran across CAM TIMING OIL CONTROL VALVE, but again it does not point it out on the diagram? My car is approaching 120k and it seems like something else comes up as soon as I fix one thing so I am just trying to get ahead if I can and prevent re-doing the same task twice lol. Thank you for all your help!

[@HelpingHandAutoRepair]

Goran Lulic Yes there are small o-rings on the underside of the valve cover. I don’t recall these coming with the valve cover gasket kit. Then again this was a while ago. It very well may have come with my gasket set. They should be able to be found pretty easily at any local parts store or the dealership. Thanks for the kind words!

[@nimpster100]

I have valve covers off and everything looks good compression good and all 6 cylinders I just don't know why cylinder one has a misfire

[@HelpingHandAutoRepair]

dontavious moore well the valve covers need to be replaced like you’re doing. Clean the oil out of the spark plug tubes (just take the new plugs out and let the oil run into the cylinder) clean the plugs and put them back in. After this if the car is still misfiring on cylinder one then you need to make sure that the new coil pack you got isn’t defective. Maybe exchange it for another. Or go with a different brand. If it is still misfiring then you need to swap the injectors from 1 to 3 or 1 to 5 and see if it follows. Injectors can also cause misfires.

[@HelpingHandAutoRepair]

There is a plenum gasket/intake manifold gasket. They usually are one in the same. However most V6 engines will have an upper and lower intake manifold/plenum gasket. Shouldn’t need the lower gasket since you don’t even have to take that off. The upper gasket should be all that’s needed. Unless he or you want to replace the lower one.

[@HelpingHandAutoRepair]

You don’t need to change the lower one. Normally when you buy a valve cover gasket set, it will come with tube seals in the kit. If not, you need to buy them. That is considered “apart of” a valve cover gasket replacement. The car in this video was a customer’s car. I honestly can’t remember what they gave me in regards to parts since it was so long ago. I am quite confident that I would have told them to replace the tube seals.

If you didn’t replace the cats with new units, you will have the code and the smell until you replace the cats. The cats are most likely clogged causing it to run rough.
