Question about Opel Astra
How can i check valve clearance?
They are automatic if you have a lot of tapping with engine running cold then they have warn out. there is a spring and ball on the underside of the tappet when the spring goes weak or snaps this is the problem. easy just to replace the set ( hard to get the centre part out that hold it in place). inlet and out let. you will need to redo the timing as the belt needs to come off, usually best to change the belt at this time.

well, I can see ur message has been here for quite some time. Most probably you got the answer to ur request.
I just did the valve clearance on the engine of my SJ413 that has the 1000cc engine of an SJ410 :
When cold: 0.13mm Intake and 0.18mm Exhaust
Engine sounded well and worked fine after that.

0.10 - 0.15mm inlet
0.18 - 0.23mm exhaust
but you must be carefull because the top of the valve seat becomes concave from wear, a feeler guage will not give the most accurate reading, hope i have been of some hel

tiburon uses hydrolic lash adjusters there are no valve lash adjusting If you hearing a pecking sound on the top of the mtr try some oil additive or replace the hydrolic lash adjusters
