Default Valve lash adj before T-belt?

Hey, I have a quick question for anyone who might have the answer. Please guessers dont answer, only people who know for sure. I am planning on changing my timing belt as soon as my water pump comes in, however in the mean time would it be ok to go ahead and adjust my valve lash? Or should I wait till my new belt is in? Basically my question is, does a new belt affect the valve lash?

Nope. Do the valves anytime you like.

The easiest way to do the valves is to ignore the factory directions. Instead, turn the engine with a 19mm socket and suitable extensions, COUNTER-clockwise until all four of one cylinder's cam lobes are pointing straight up to the sky. Check those. Now turn the engine so another cylinder's lobes are pointing up. Check those. Do this two more times and you're done.

To save turning, you can also check when one cylinder's intake lobes and another cylinder's exhaust lobes are pointing straight up. You just need to remember which ones you did and which you didn't.

This method totally eliminates the possibility that you might accidentally be on the slope of a cam lobe, which is what results in excessive clearances when following the factory method. This method is also immune to any complications that might result from the old belt being off a tooth.

It doesn't matter when you do it, but while you've got the belt cover off would be aconvenient time. I'd probably do it immediately after tensioning the new belt.

Plus you got to do the adjustment while the engine is cold.
