General Motors Engine Center Screw Valve 055562224 Generic

The owner of the repair shop recommended this set, it is cost effective and is as good as OEM. It has been installed and in use for a month now and no problems so far.

The parts are well made, no trouble with installing the holes in the wrong places, and the vehicle doesn't have that intermittent shudder anymore.

Before the engine light on and off, the garage said the camshaft problem offer high. I bought this kit with the mindset of trying it out, and after looking for a familiar master to replace it, the most obvious feeling is that in the morning when starting cold, that kind of ‘click-click-click-click’ scary sound is gone, and now it fires up very crisply.

After installation, oil pass-through was significantly improved and the dashboard no longer flashes the ECO light.

The workmanship on the new rocker arms is noticeably more subtle compared to the stock wear parts, and the ‘clicking’ sound on cold starts completely disappeared after installation.
