OCV Strainer Cleaning Guide (vvt-i & vvtl-i)
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.
