valves/cyclinder head long term reports
When I bought my Yaris it was for a long term vehicle (hoping 20+ years). The one weakness I identified was the cylinder head design. I was very surprised with the shimmed mechanical valves. Adjusting valves on this car is almost out of the question for a DIYer unless you invest in a bunch of shims.
My car is at 30K, I notice a little ticking. But I am wondering if anyone has had a valve wear out of adjustment and what milage it takes for that to occur? Just looking for feild reports/discussion. |

Yeah, most cars get hydraulic valves these days!

In any case, I was always under the impression that some ticking was good. No ticking means your valves have stretched and are now too long. |

I've wondered about the valves. Mine seems pretty noisy, but I don't have anything to compare it to. I guess I need to visit a few Yaris owners and listen to their engines idle.
