valve adjustment spec

advance · 03-16-2003, 10:40 PM

my car is a 2000 impreza 2.2l and it is in major need of a valve adj. I can't find any manuals for my year without selling out $300 bucks so I was hoping you guys would know how far to adjust the valves to. I work at hondu so i should be able to do this i just need the specs.
thanks
brian

My 01 has them printed on a sticker under the hood. It's actually on the hood underneath.

i don't have my hood no more

kturner · 03-17-2003, 11:40 PM

My hood says:

Intake 0.10 - 0.25 mm
Exhaust 0.15 - 0.30 mm all cold.

Shop that did an adjust to factory specs calls for

Intake 0.008 inches
Exhaust 0.010 inches per factory spec. Also cold.

Cobb wants 0.007 and 0.009, respectively.

Somewhere in there. There was a good write up at www.nothingserious.net/valves.html but that url seems bad.

From the horse's mouth, I swear. I was having a hell of a time getting my lash right after my cams were installed and Josh said to do it warm... sure enough the best I've gotten it was when set warm... go figure.

and also more then triples the risk you run of burning a valve

Jeremy, I was scratching my head too. I've always done valves after the car has cooled overnight (at least on all the inline 4's and the first few times I did the suby).
