it seems like you spent more money on this project than you would have spent just buying the vvt solenoid and replacing it?

I did this for my sienna, after a year of pre-lubing the rattle is gone

I did what someone else considered a vvt rattle fix on KZbin and worked. Just replace both valve cover gaskets and double o-rings.my 2013 Highlander has 195k km. All valve cover gaskets were hard and drying up. Althought no leaks the double orings seems to be the culprit. I think the quick rattle on startup is shorter than before

Please SHOW US HOW THE PARTS R LAID OUT! Your video is not helpful unless we càn see more. Im sure many poeple would love to see your setup. It sounds very smart! Very cool by the way! 😊😊 Id b doing it forsure i just need to see were you conect3d things and more of a complete discription. Thanks in advance! There r literally tons of these engines out here.

Absolutely brilliant!

Hey David. I was curious if you ever got around to making a detailed video on how to build and install this prelube system? Thanks for the video.

I got the same vehicle and same problem. Thx.

Did he use a pump motor to pump the oil into the motor

I have 2008 highlander with 178k miles no rattle but I also run 5w30 instead 5w20 that Toyota recommends for fuel efficiency. Do my oil changes every 5-6k miles and make sure to aways put 6.5 qrts. Keeping oil at recommended levels helps VVT gears from overheating and eventually rattling. Definitely one of the best v6 engines in the last 20 years.

Is this the rattle upon startup? Mine has done it forever but 220k miles still runs perfectly

Awesome vid, I just picked up an rx and I was unaware of the vvti issues. What kind of fitting did you use on the propane tank to add the oil and how did you position it onto the front end? What kind of Tee did you use?

So 2 years later you still haven't deemed it fit to show us how you did it

Brilliant. Id love a detailed video also

“This is a very bad video.” - and very bad advice with the most ghetto fuckin shit ever. Change the oil on time you gump

Run a flush. Use sone restlone nano pirme in the subsequent oil change. Fixes the issues

Can u make a video step by step. Thanks

…or just use 5/40 full synthetic engine oil , that got rid of my 2008 Highlander/Kluger start up rattle

Would adding a oil pump between the oil drain plug and oil pressure sending unit work as well? Making the pump work only while cranking the engine

Hey David, I have watched this several times and conceptually makes sense but I am having hard time finding the parts. Would you be willing to put together the same parts and sell to me? I have 2 cars I want to do this to and it would help greatly.

Interested, is it possible to demonstrate in a separate video how did you install it? I have the same issue on my both highlanders 2008 and 2010

Very dangerous at A Toyota tech and owner of a highlander I implore not to do so. Easier or just as easy to replace phaser. You will be glad in the longer run. Best wishes

This is not the right fix. The correct fix is to get the VVTI gears replaced. While the startup chatter is rare, it is fatal when it gets really bad.

Good video BUT also LAME!!! Video summary... This is what I did (a good idea), I want to see if there is interest in this video and TALK in the comments about making a more in depth DIY one, but then I won't... and I will continue to ignore MANY, MANY, requests for a DIY video on this subject as I am not going to put any more actual effort into showing you HOW I did this (other than randomly commenting). THANK GOD 99% of KZbin does not use this same philosophy.

Would be life saving if you made the build video, this rattle is driving me crazy. Thanks !

I want to do this for my 2010 Rav4. Would be so grateful if you could add a parts list to the notes.

Come On Dave you have to lead us to the promised land please make a video thank you

Do you think of it wasn't fixed it would be a serious problem? Say I'm planning to drive the car into the ground and don't mind the rattle start

As basic as this is this would be a great video to actually tell us all how to do this as well. An ABC with parts list and even links to stuff to build it. I’m so sick of the rattle lol

Its what a crappie chain timing suppose to do it takes up to a minute for the motor to lube up n quiet down.

How did you do it ? Can you show us the part and how do install it? please!

We knew you could do it. *Pride*

So how did you fix it? please do a better video.

What kind of reservoir did you use and what kind of solenoid did you use my Lexus has the same problem

David, can you link a parts list and general instructions pdf link in your Video Description box? A detailed video would really be nice, but the instructions are fine if that's quicker. Even faster would be to reply to my comment below where I tried to put together a parts list. You could copy and paste what I wrote, and then correct it and add explanatory comments. When you do an updated video, you could title it, "How to Dramatically Extend the Life of Your Vehicle's Engine for about $100". This type of system could be standard on all vehicles to optimize engine life, not just on vehicles with engines that rattle at start up.

Seafoam treatment to clean passages in the pin not closing in the vvt sprocket then synthetic 0-40 to lower viscosity @ startup or 0-30 for colder climates is another option.

Hi David, this is a very common problem on Highlanders, and if you could make a video showing how it is done it would help a lot of people out including me. Looking forward to it!

Hey David would really appreciate a detailed video and the parts you used , because certain Lexus models have the same cam shaft rattle on cold start up including mine, due to the oil draining out, thanks ✌🏽

William Whitlock Hi David thanks for the video. do you remember what type solenoid valve you have been using.

I did the video showing my solution for the rattle problem just to see if anyone is interested. If I got enough attention I was going to make a better video showing how it is done . I now have this on a few other vehicles and it seems to work quite well.

Thanks for posting. This is a very creative application, but the explanation assumes a fair amount of specific knowledge, which people new to this game, like me, don't have yet. Even so, I know what is possible down the road, and thanks for that. I have a 2001 Camry with a 2AZ-FE that knocks on start up, and I'm curious if something like this could resolve the issue. BTW, do you add in a little extra oil on oil changes to account for the oil that sits in the reservoir? If so, how much seems to be working best? 1. Proper sized propane tank reservoir (~1.5 qts of oil) 2. Oil pressure out (where sending unit would normally be) is directed into tank using hoses. 3. Solenoid valve releases pressurized oil when ignition is turned on. 4. Has switch to allow 60 lbs. of oil pressure worth of oil to be stored in reservoir on lower dash board. 5. Fitting (1/8 in. imperial to 1/8 in. pipe thread). 6. 1/4 in. dia. hose x 3 ft. hydraulic line (at tractor supply shop, no doubt down the street in every big city. ;-) 7. Hydraulic line goes up to a valve (connected to the propane tank???). 8. Propane tank had fitting (???) welded to it.
