Some key terms; “It’s not a tickler”, “hit it like you mean it”, “wipe your nozzle”. Words to live by from the master.

Glad someone is picking up what I'm putting down. Cheers

[@murraycottle7049]

And a "finish by hand" is highly recommended 👍

Thank you so much for making this video. I will be doing this job this weekend and this video is helpful

[@CartuneNZ]

Glad to help. Cheers Kelvin

[@wyzmaro9774]

At this point should I just do the Timing Belt, Water Pump and pulley's? Should I put in Cams now or wait to port the heads? I have a 1999 LS400 1UZFE VVTI.

Hello Kelvin could you please comment the OEM part number to the genuine pcv valve grommet from Lexus Toyota, Regards

[@gang6009]

Thanks mate

[@chiwi9887]

Thanks for this mate, was gonna do this over lockdown but wasn't sure if I needed silicone. Getting fly with the editing aswell👌

[@CartuneNZ]

Hopefully this cleared that up. Thannsk , sometimes my editing work well. Cheers Kelvin

[@mrt4995]

Could you please tell me what size socket you used for the spark plug tube seals

[@Yash-jo8hv]

Boss you have the link to the product you bought.

[@MrShanilicious]

Best technique I've ever seen on removing the spark plug well gaskets. 'Use it like you mean it!'

[@CartuneNZ]

Absolutely. No point hitting it a million times with a little hammer. Cheers Kelvin

[@Parkertip]

What do you clean these with? What is is safe to use?

[@1uzsurfnz670]

Hi Kelvin great Vid. With regards to the Pcv valve, on my forced induction, what I did is I’ve drilled out the pcv valve and pulled out the spring and ball bearing and now free flows into a catch can and wrks great.

[@CartuneNZ]

I'm glad you understand how a valve works. Ive had cars come in that are professional prepared with catch cans the the PCV valve is still in place. Pretty simple stuff to get right. Cheers Kelvin

[@1uzsurfnz670]

CartuneNZ oh by the way received the TPS plug. Thank you.

[@Maplecook]

Just did the right side today. Couldn't stop hearing in my head, "uppy bits...that's the technical term." LOL

[@CartuneNZ]

Haha. Awesome. Cheers Kelvin

[@Maplecook]

@@CartuneNZ On Friday night, I did the valve cover gasket on my 97 Celica. As I laid the rtv down, I (quite unexpectedly and CLEARLY) heard your voice in my head again: "Uppy bits..." haha

[@sixcentsmedia]

"This is a bit like a cooking show...heeeres one I prepaired earlier"

[@CartuneNZ]

Absolutely. I used to be forced to watch those cooking shows growing up. Haha. Cheers Kelvin

[@Yash-jo8hv]

Where did u get the gasket from

[@Yash-jo8hv]

What year engine is the car

[@Thatotherschmuck]

great video, what kind of silicon are u using by the way

[@CartuneNZ]

Thanks for the compliment. Im using Wurth Grey silicone. Any quality automotive silicone is normally fine. Cheers Kelvin

[@baddestburrito]

Great video, Kelvin! Could you please clarify 2 things, please? 1) Why did you separate the washers from the tappet cover bolts? What is the consequence of just putting them back in, the way they came out? 2) Is it correct to assume that -- because the head is aluminium -- that when screwing the bolts back in, said bolts should be only very lightly hand-snugged? I mean, "baby-fart," gently snugged. Thanks in advance.

[@CartuneNZ]

The washers go hard as rocks as they are old. They are designed to be squishy when installed to allow for expansion and contraction as the covers warm and cool. Done incorrectly they either leak or much worse snap off the corner bolts of the covers. Who would reuse 25-30 year old rubber washers?

[@baddestburrito]

@@CartuneNZ Thank you, Kelvin! I thought that they were metal washers. This makes much more sense now. Cheers!

[@docfischer7291]

“Lubricate it before you stick it in the hole.” How true in life. My old shop teacher was a genius. LoL

[@CartuneNZ]

Never go in dry. Haha. Cheese Kelvin

[@jaspertheron5822]

Hi can you please explain the deference between the 2 valve cover outlets on a 1uz-fe/Ls400 engine. I know that the one with the oil filler cap is where the PCV valve sits. But what is the one for under the throttle body, the big 90° elbow fitting witch ties in before the throttle body inlet. Want to find out if it will do anything by installing a oil catch can on it as well or leave it as is. Problem is that the 90° elbow fitting is facing forward making pipe routing difficult and one will need to remove elbow, tap hole to fit a 3/8'' BSP brass 90° male elbow barb hose fitting so it can face the firewall. The 90° elbow on the throttle body will then also need to be reduced so 3/8"

[@xavieuhr]

just did my valve covers today, thanks for the advice. and to everyone out there, take his word about snugging the cover bolts on the edges only just hand tight. he was 100% correct about cracking on the edges. i found out the hard way and cracked my corner off which caused a massive leaked. hand tightened it this time and no leaks

[@4funner66]

Kelvin, do you ever drill off the rocker cover internal baffles to better clean underneath them? Or is that a bad idea.. just wanted to ask before I stuff a rocker cover by drilling it

[@CartuneNZ]

Yes, its on my video list but its a long list. We generally acid dip the bad covers which gets 95% of the crap out so drilling covers isnt required

[@REAPER3fitty]

Just spent my Corona money on parts for the SC400. All OEM. Plugs, wires, caps, rotors, timing belt, timing belt tensioner, valve cover gaskets, power steering pump, water pump. Also got a steel braided high pressure power steering line from Driftmotion. I'm going to buy spark plug gaskets tomorrow. Also going to add some serious horsepower by painting the valve covers. Blue to match the car so that'll be double what you usually gain. Any other suggestions Kelvin while I'm doing my mini overhaul?

[@CartuneNZ]

Hello. Looks like yo have the main stuff. Some seals for the front and maybe the bearings on the front accessory belt. Painting the tappet covers is worth at least 10hp at the rear wheels. Cheers Kelvin

[@billygreenhorn9275]

Lucky guy...working on 1UZ's all day ;) Did you re use the PCV valve Kelvin? Is this the car you just got recently? Have a great day and stay healthy.

[@CartuneNZ]

This is a customers car. My one is VVti unless you count the 3 soarers I recently acquired. Im staying well hidden in my workshop at the moment and happy to be doing so. Cheers Kelvin

[@hammuffins2645]

Have you designed or mentally designed a way to fabricate a Ute LS400 for the farm?

[@CartuneNZ]

Thanks to that crazy suggestion I have however after trying it in the paddock it tends to grade all the bumps and goes no where when traction control is turned off. Diff definately requires both wheels to operate on soft ground.

[@josephlewis8839]

Can you do a video on the best way/"easiest" way to replace the egr pipe on a 1996 ls400?

[@CartuneNZ]

If I get an ls400 which needs egr removed I'll do a video however most cars I see are jdm which don't have egr. Cheers Kelvin

[@myyoutubechannel3161]

Hi Calvin. I have a 1995 lexus sc400 1uzfe. i have light smoke coming from the rear of the engine not sure where it is coming from. Also im having a low rpm ilde at around 500 rpm car idles high at start up for about 10 minutes then idles low.. Car has been sitting for a year. And had to replace the battery a couple times. Are you familiar with any of these issues ??

[@myyoutubechannel3161]

Pretty sure my valve cover gaskets are shot and are leaking on the exhaust down below .. On right side.

[@CartuneNZ]

Tappet cover gaskets are common thanks to age, idle speed controls I service and clean TB. Basic maintenance and servicing also helps. Confirming no parasitic voltage draw and alternator function for battery issue. Cheers

[@TaylorMadejdm1975]

Hello Kelvin can you remove the valve covers without taking off the intake manifold...? 👍

[@CartuneNZ]

Absolutely can be done without removing the intake. Remove the throttle body is required on non vvti.

[@codenameFourtySeven]

This is not a tickling device..Use it like you mean it! Cracked me up haha. Great job! Toyota 2GRFE engines develop a lot of grease in their tappet/rocker covers causing the car to blow blue smoke.

[@CartuneNZ]

glad you enjoyed it. While the 2GR are a great engine Im going to stick with my UZ stuff. 8 cylinders for me. Cheers Kelvin

Which type of silicone is best or that you would recommend?

Threebond is the factory option and awesome stuff. Any high grade silicone is fine, personally I use wurth grey.

The silicone guy must have owned my car last too! Found two different types of silicone on the inside of my valve cover gasket haha

I replace lots of PCV however this one tested out fine. Cheers Kelvin

[@5lugfury352]

You forgot to paint them yellow or blue first lol

[@CartuneNZ]

I really like the clean alloy look with a bit of clear coat over them. Maybe I need an engine with red tappet covers . As we all know red is faster. Cheers Kelvin

[@5lugfury352]

@@CartuneNZ I agree I love the stock coloring. When working on mine I ended up making them yellow because after seeing old yellow over and over again, it grew on me. Then again figured blue truck with yellow engine isn't too bad.

what brand valve cover gasket set is that? Can i use a cheap set or get genuine parts

These are non genuine set however not a really cheap set. Look for set with all the components in it and a brand you know the name of and they are generally ok.

Use a new grommet, They are a soft rubber and should slip in easily. Cheers Kelvin
