SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its timing mark îOî of the No.1 timing belt cover.

|
(b) Check that the timing marks of the camshaft pulleys and timing belt rear plates are aligned. If not, turn the crankshaft one revolution (360 ∞)and align the mark as above.

INSPECT VALVE CLEARANCE (a) Check only those valves indicated in the
∑ Using afeeler gauge, measure the clearance between the valve lifter and camshaft.
∑ Record outof specification valve clearance measurements. They will be used later to determine the required replacement adjusting shim.
Valve clearance (Cold): Intake 0.15ñ0.25 mm (0.006ñ0.010 in.) Exhaust 0.25ñ0.35 mm (0.010ñ0.014 in.)
(b) Turn the crankshaft one revolution (360 ∞),and align the mark as above. (See procedure step 5 (a)) (c) Check only the valves indicated in the Measure the valve clearance.

ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
∑ Turn thecrankshaft to position the cam lobe of the camshaft on the adjusting valve upward.
∑ Press downthe valve lifter with SST (A), and place SST (B) between the camshaft and valve lifter flange. Remove SST (A). SST 09248ñ55011
∑ Usingcompressed air and magnetic finger, remove the adjusting shim by blowing air into the shim (b) Determine the replacement adjusting shim following the Formula or Charts:
∑ Using amicrometer, measure the thickness of the removed shim.
∑ Calculatethe thickness of a new shim so that the valve clearance comes within specified value. T ………. Thickness of used shim A ………. Measured valve clearance N ………. Thickness of new shim
Intake N = T + (Añ0.20 mm (0.008 in.)) Exhaust N = T + (Añ0.30 mm (0.012 in.))
Select a new shim possible to the calculated values. HINT: Shims are available in seventeen sizes of (0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 (c) Install a new adjusting shim.
∑ Press down remove SST (B). SST 09248ñ55011 (d) Recheck the valve clearance.

UPDATE: A limited supply of the original best-selling Lextreme 1UZFE EGR Delete Kit remains. If you own a 1UZ from 1990-1997, you really need to get this kit! Email me at [email protected] for help with ordering or questions. This will probably be the last kits I have made.
All other parts are SOLD OUT and won't return, including the LS400 and SC400 turbo kit, rebuild kits, supercharger and performace torque converter. We're not an auto parts supplier and I can't respond to inquries for random Lexus and Toyota auto parts.
