if you have no clearance then you need to order a thinner shim for the shimbucket from toyota...if you have the trsm for the supra it will explains how to replace shims and how to remove shims...it's a pain but the head doesn't need to come off to do this and neither do the cams...so once you use your feeler guages and see that some of the clearances are not right you need to write it down in order per valve per cylinder...once you are done and wrote everything down you need to remove the valve shims that are out of spec (KEEP THEM IN ORDER)...then mic the removed ones and add the difference that you found with the feeler guages..then subtract the toyota clearance then go to toyota and order the proper thickness shim per valve.
Did I make sense?
ok guyes i got the cygnusx1 online tsrm, but cant find the valves clearance and shim part... ne 1 can help?
what is the clearance spec? i got a .006 inch filler gauge,(smallest i got) and in the 6th cylinder it wont fit in... others looks ok...

i thik i found them...

so its .006- .010 for the intake side? (between camshaft and lifters at TDC)??

kk so shims are bad? the .006 gauge wont fit between cam and lifter... so whats next (woot ij ur there 
)
)Time for a new set of feelers that go smaller
You need to find out exactly what the current clearence is then measure the current shim and subtract what's needed to get you into the right 6>10 range.
It's NOT rocket surgery but you do need accurate measurements
I'd still pull the cams and redo the Leakdowns just to be sure it's not a BHG.

kk ima do thiss... so i need low feelers and a micrometer? or just a sliding gauge will do the job?
and ehm what if theres NO clearance between cam//lifters :O? oh i thik i will take the thinnest shims i got, put it on the cylinder then check with it...
anyway how much cost these shims?

Frenchman......if you go to a machine shop they may sell you some shim material of any thickness you need....infact I could mail you some Percision shim material that can be used as feeler guages.
Bob: Digi Verniers are cheap now and good enough for this job.
Yep if you can't get a feeler in at all swap in a thin shim.
If you go through all the valves and record each on then figure out just which shims sizes you need someone here may just have the correct ones.
Thinner is always more common than thick shims.
Failing that there are Yamaha bike shims that fit that I believe are cheaper than Toyota shims, either way you might only need a couple so it's not a big expense.

ok ima try it, i havnt tried to remove one yet, is it really easy ? like u remove cam and just pull them with hands? some 1 told me they are just inserter here and are free... camshafts hold them...
its the kind of job u must be alone without nothing distracting you, and touching anything...
for the pressure test i think its a succes for the 6th too, i got the compressor to 105 lbs, NOTHING in radiator, nothing in both manifolds,just some in oil passages (i can hear it on the oil passage for the camshafts too).. but theres no water in rad, but no sound at all on all cylinders...
i think the shims problem may be swapped ones, since when i got my head the camshafts were loose... they must remove them to face the head? maybe some slipped off and they didnt told me...i checked them quickly and all seems ok (i said quickly) only the 6th and 4th intake side the .006 gauge wont pass, ima re-check everything and write the thing on a sheet of paper...

That's why I said check them all and record the results on paper.
You might find a couple of loose ones that should have been in #6 <fingers crossed>
Whenever I do head work I label a bunch of baggies and keep all the parts in order right up until I'm ready for final assembly.

ok for the shims part im good, not too complicated...
for the head gasket, since i dont hear anything in rad its ok? (i mean i can put the exhaust manifold,turbo etc... back in?) cuz its a pain if i must remove it again... and since i may be waiting for the shims, ill do that until it arrives...

Ok try this as a final check
Block off the Rad overflow hose to the recovery tank.
Get a balloon and stretch it over the Rad neck
Plug the compressor into #6 and observe the balloon.
The noise you're hearing in the crankcase will be blowby from the rings as is normal at this stage.

kk ima do it before installing the turbo etc... if its not growing and the compressor get 105-110 psi in cylinder then im 100% sure theres no head gasket problem?
LMAO olitician mode on: You can never be 100% sure
If the balloon doesn't blow up you can be sure it's sealed to the water jacket!
Keep in mind it really needs 5+ heat cycles and a retorque to be buttoned down.

I just re-read this thread.
Still no valve clearance measurements? No proper compression test yet?
C'mon Bobpogoman, you gotta follow directions (in order), or no-one can help you.
Frankly, I'm surprised IJ has been this patient. I gave up when you never responded to my post (#40), and have had to be retold the same shit over and over.
Maybe it's a language thing, but I'm done.

He is but he is kinda confused...that and it's hard to understand him. He's takeing measurements but he's new to this...IJ see's that so he's being patient...we just gotta be patient with the frenchy LOL.
ehm...okk.... bah as i know i followed every ij things asked me, sorry for long times but im working ...
for the comp ratio i re-did it its posted somewhere, with wot with the same result, for the measurments of the clearance i just did it...
for exhaust side everything is find but one, on cylinder 5, 1 of the valves got 0.011 clearance and the other got 0,007, -1 from spec.. but the 0.008 gauge can enter but with some pressure, so i think its like 0,0075 so i dont think i must remove exhaust cam right?
for the intake side, ill tell them (clearances) from timing cover to firewall order, the 12 valves.

so, i got 4 shims to replace... i got a spare 7m in the garage, actually ima remove the shims from it and see what i can do... also ima remove my intake cam and start fixing it... i bought an electronic caliper.
for the pressure test with the baloon its a succes, wont move a little.
