Head Upgrades on 1.6 Valvematic

[AndyBeast]

So my little Auris is quite poorly, it's loosing pressure on cylinder 2 and needs some serious TLC. The garage doing the work are doing a wet pressure test first but believe (from the noise and feel of the car) it's a knackered exhaust valve therefore the head will need looking at. On the basis it's gonna cost a shed load of money to fix anyway is there any performance upgrades I can do on the head while it's off?

Port and polish ... That's about it ... And a damn good clean

Any ideas what caused it?

Nope, started getting check engine light and after getting codes read, parts changed (plugs, coil packs) and injectors cleaned it left only a mechanical problem. Dry pressure test has shown a massive pressure drop on cylinder 2 and, as previously mentioned, mechanics believe it to be an exhaust valve problem but can't diagnose for sure till after the wet pressure test.

It's been a long time since I had an exhaust valve burn out (or, to be precise, two), and it wasn't on a Toyota, but TBH it wasn't such a terrible disaster. A couple of valves, springs,  cam followers, and in my case a lightly shaved head. Nothing that a good old-fashioned motor factor couldn't have taken care of.

Just hope you get it sorted. 

Be taking mine out for a "Battery charge run" later.

Even the mechanic was surprised when I said it was a Toyota. Apparently I'm just that unlucky 😡
