To adjust tappets on a 3-cylinder engine, first ensure the engine is cool and remove any necessary components to access the valve cover. Rotate the crankshaft to align the timing marks, then check the clearance of each tappet using a feeler gauge. Adjust the tappet screws or shims as needed to achieve the manufacturer's specified clearance, ensuring to tighten lock nuts after adjustments. Repeat this process for all cylinders, following the firing order to maintain proper timing.
With No1 cylinder at TDC adjust the following valve clearances, No. 1, inlet and exhaust No. 2, inlet No. 3, exhaust No. 4, inlet No. 5, exhaust Then turn the crankshaft 1 full turn so that No 6 cylinder is at TDC and adjust the following valve clearances, No2. , exhaust No. 3, inlet No. 4, exhaust No. 5, inlet No. 6 inlet and exhaust. Both inlet and exhaust clearances ar 0.4 mm with engine cold. This info is from the original service manual
A 3 cylinder engine : Compact in size, cheaper to built, light in weight, Less fuel consumption. 4 cylinder engine: bigger in size, smoother sounding than 3 Cylinder engine.
There are now not many cars in the United States that are made with a 3 cylinder engine. A couple of the vehicles that were once made with a 3 cylinder engine is a Geo Metro and Dihatsu Charade.
#3 is third cylinder from the pulley end of engine.
An engine cylinder misfire has been detected in the # 3 engine cylinder
There are cars that have engines with only ( 3 ) engine cylinders such as : The Chevrolet Metro with the 1.0 liter , 61 cubic inch , 3 cylinder engine ( 1999 )
Cylinder # 3 is on the passenger side of the engine , back cylinder (on your 4.2 L V6 engine the cylinders are numbered 1 , 2 , 3 from front to rear on the passenger side of the engine and 4 , 5 , 6 from front to rear on the drivers side of the engine)
It depends upon cylinder in car. 3 ignition coils - 3 cylinder engine. 4 ignition coils- 4 cylinder engine.
B. 127
One car was the 1999 Chevrolet Metro , you could get a 1.0 liter / 61 cubic inch , 3 cylinder engine
With the engine at operating temperature remove the valve covers. With the engine idling back off on the rocker arm nut until the rocker starts tapping. Tighten the rocker arm slowly until the noise stops. Then tighten it 3/4 of a turn more. Do each one the same and reinstall the valve covers.
On a 4-cylinder engine with a firing order of 1342, if number 1 cylinder is on the exhaust stroke, the number 3 cylinder will be on the induction stroke.
