VALVE ADJUST?Mefarri said:so.... I don't understand. Why on earth would a hole being filled cause more noise. I have the same noise whenever the motors warm, and would like for it to go away. Any solutions?
before you cleaned the ocv, did it make a clattering/rattling noise when accelerating also? would brake cleaner work?GSBoek said:Of course this thread would not be complete without adding the infamous VVT-i related noise. Excuse the poor quality vid I put on Putfile. Watch how the tractor noise goes away when I pull the VVT-i OCV plug.

very nice detail, i have this problem its shooting out the p1693 code, and my lift isnt working, BUT it works sometimes, sometimes i try it and it goes tatatata, like its misfiring, or fuel cut off, u know? and the dealer wants to charge me 405 for the fix, 140 for cars parts, 300 for labor, now i have nothing close to 400, im in debt actually, cuz ive borrowed some money here and there, so i cant fix this problem at the dealer. so i was thinking of maybe checking the ocv screen, since it works off and on... but, im scared that i might not be able to put tires back the stuff together...HELP?
Nice photos and guides. Your post is useful information about cleaning the VVT-i & VVTL-i OCV Screen. I apply it in mine. Mine are very neat now. :gap:I have a day of today (Flagday here) so I decided to make this thread about the Oil Control Valves=OCV.
Most of you know already but for those who don't:
The 1ZZ-FE engine in the GT has variable valve timing only, or VVT-i.
The 2ZZ-GE engine in the GT-S has variable valve timing AND lift, or VVTL-i.
Consequently GT has one OCV, GT-S has two OCVs.
First the Timing OCV:
This is its location on the head of a 2ZZ, more or less the same location on a 1ZZ.
This is how it looks like.
To help keep particles out, the OCV has a metal mesh strainer to filter the oil going to it. This is its location:Behind that bolt in this pic.
If you remove that bolt the strainer is located in that hole, but this one doesn't have it as I used it in my engine and the old one fell and got lost.
As part of regular maintenance I would recommend cleaning the strainer every 30k. It is a pain to get to if you don't remove the alternator so plan it to do so when you change your drivebelt.
