Anyone Check Their Valve Clearances?

My finacees Echo has some sludge (bought it used at 287,000km) so I'm not too sure what type of clearance I'll end up finding.

Sounds good and thanks again for the info.

I'd be suprised if the clearance is out of spec high and expect it will be slightly out of spec low. But it might be OK. Many must be.

It's funny there used to be a recommended mileage interval to check valve clearance and then Toyota did away with that recommendation all together. I have heard of people putting a ton of miles on their Yarises and never checking the valve clearances one time. I imagine there is the occational engine that will have valve issues but it appears that is rare with these motors.

After dismantling the head I'm working on, I was surprised that the valve had no visible makes from their seats. It's like they were all new still. I think the head oly had about 60k KM though so relatively low milage but still, I thought I'd see something. I think they have a coating of some kind on them.
