Rotate engine until #2 cylinder is on the intake /exhaust valve overlap then adjust #5 valves. In this part, we are going to learn how to check valve clearance, check intake system, add grease, check fuel pump coupling, check fuel injector and so on. With the #1 cylinder on compression stroke adjust #1 #2 #3 #6 #7 #10 valves to .025 in. On hydraulic lifters, there is no gap, and it is the oil within the lifter that provides the cooling time (lash), even though constant contact remains between the rocker arm and valve stem. This article was written somewhat backwards, and there is a very good reason for doing so. This process is mandatory with Hydraulic or Solid tappet camshafts. Repeat the above steps, starting at #3 through #10, but use the next cylinder in the sequence. Torque Value: 24 Nm [18 ft-lb] Mark the pulley/vibration damper and rotate the crank-shaft 360 degrees. (7) Tighten the oil dipstick to a proper degree. endobj The valve adjustment of multi-cylinder engines is generally adjusted in two adjustments. I have the same engine and this was the proceedure i followed with a perfect outcome:-. Every time a piston reaches TDC the stroke will either be compression stroke or and exhaust stroke.Follow The Firing OrderThe firing order on an in-line 6 cylinder engine is 1-5-3-6-2-4 I always start at #1 cylinder. If the engine runs rough or poorly, or is making excessive valvetrain noise, repeating the procedure on at least the troublesome valve(s) will be requiredsomething went wrong. And check the turbocharger shaft for not being free spinning. In case that any of the above problems occur, the damper should be replaced. Working hours: Be certain to check the oil level in the engine to ensure proper capacity. First, warm the engine to operating temperature (about 15-minutes) and then quickly remove both valve covers. . When working on older high mileage engines or those that use poor quality lifters you may experience a condition where the lifters bleed off pressure (drain the oil out of the lifter body), causing inaccurate valve adjustment. All injectors will first buzz (audible feedback of the injector solenoids energizing the injector, Read More KOEO Injector Electrical Self Test (Injector Buzz Test)Continue, Very informative. Cold adjustments should only be used on new engines as a preliminary adjustment on the engine stand. Just remember, the more valve lash, the louder the valvetrain will beand damage may occur if not careful. Line up the notch on the belt pulley and check to see if the the #1 valves are loose. With the harness removed the ECU is next (10 mm socket) followed by the mounting plate (4 valve cover stud nuts and one fastener on the block). 2. Unbelievable as to how far they have come.
