Hello everyone! I want to tell you how to adjust the clearance in the valve 4G69. The fact that the engine 4G69 no hydraulic compensators gap, how to 8G. . Therefore, once a 60000 miles it is necessary to perform the verification and adjustment of the valves. As the gaps are not regulated automatically, this procedure should be done, if you install a turbo or supercharger. And also, if you use gas equipment. A what? "Need a wrench to 10 mm, flat-blade screwdriver, thickness gauge and service manual. I did this on my previous 9G, when installed supercharger. Therefore the images are the details of which you have no. So, let's begin.
Turbo - it is a snail, but the bitch is very fast.
Then you must remove the top cover of the belt. She sits on the 3 bolts on 12mm and one bolt at 10mm. But the bolt cover is not fastened, as it were inserted. Unfasten the two clamps that hold the cable over the top of the cover. Avert bolts and remove the metal bracket to which was attached cable. Cover is easy to get up

Measure the valve clearances. There was a need for clarity. In the service manual on page 11A-11 specified gap intake: 0.20 mm (0.008 inch), Exhaust: 0.30 mm (0.012 inch). However, this is not true. More precisely, this is true for the Engine coolant temperature: 80 − 95°C (176 − 203°F). It's very inconvenient. Therefore, open the page 11B-22. Here are written valve clearances for a cold engine. Standard value (in cold state):
<Vehicles for CALIFORNIA emission>
Intake side: 0.11 mm (0.004 inch)
Exhaust side: 0.21 mm (0.008 inch)
<Vehicles for except CALIFORNIA emission>
Intake side: 0.11 mm (0.004 inch)
Exhaust side: 0.22 mm (0.009 inch)

Adjustment begins. Set the thickness gauge between the rocker and the valve. Using a thickness gauge, adjust the clearance between the valve shaft end and the adjusting screw. Attention, this is important. Are regulated by the following valves. Intake side: 1 and 2 cylinder. The exhaust side: 1 and 3 cylinder. Next. Rotate the crankshaft one time clockwise and then align the
timing mark with the timing mark on the crankshaft sprocket.
(Place No.4 cylinder on the top dead center of compression
stroke.) Are regulated by the following valves. Intake side: 3 and 4 cylinder. The exhaust side: 2 and 4 cylinder.

The assembly is performed in the reverse order. That's all, good luck to you! P.S.. Almost forgot. Gasket for rocker cover can be used again. She silicone type of keystone.
