Meownapua Registered User (3/23/01 5:30:58 pm) Reply | clearance Are you serious? Valve clearance is one of the most basic tune ups possible. If you install aftermarket cams you HAVE to adjust it. It's a big deal! What kind of engine builder are you? Anyway,the exhaust is probably the same and exhaust is usually more than intake so it's probably the same as a 16V. I'm just guessing though. Here's the specs on the 16 valve. For the 16V, shims come in increments of 0.050mm(0.0020in)from 2.500mm(0.0984in) to 3.300mm(0.1299in)
cold
INTAKE 0.15-0.25mm(0.006-0.010in)
EXHAUST 0.20-0.30mm(0.008-0.012in)
Hot(Reference)
INTAKE 0.20-0.30mm(0.008-0.012in)
EXHAUST 0.26-0.36mm(0.010-0.014in)
Oh and toyota suggests that you use SST 09248-70011 but you can just take the cam off.

 | Re: valve clearances You do it the same way that's been done for the last near-century, ie, measure the clearances and then the shims, then work out what you need from there.
You'd best not try it though, given your previous trouble with tape measure technology, as it involves using complex measuring equipment. (feeler gauges)

 | Re: valve clearances "whats a feeler guage?" = "I don't know basic engine tools, please explain."
I have no intention of spending hours and hours explaining such basic things to you. All it shows me is that once again you don't know what you're talking about.
