The exhaust is stainless steel. Heat causes stainless steel to turn blue.
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
From the cylinders, 4 individual exhaust passages converge into 2 passages and finally collect into 1.
'01 Infinity I30's have 4 O2 sensors. Two in Bank one and two in Bank two. They are located on the exhaust system. On the front of your engine you will see four harnesses, blue, red, white and black. All but the blue wire runs under the engine to the exhaust system. Bank 1 is the rear of the exhaust and Bank 2 is the front of the exhaust (by the manifold). Black and white go to Bank 1 and blue and white go to Bank 2. Go to infinitihelp/Ownership/common.com and there is a diagram of the exhaust system. Your most likely looking for the black harness/wire.
270 degrees is 3/4 of a turn
4 colours = 1 divided by 4 = 1 quarter per colourred + blue = 1/4 +1/4 = 1/2
A 1/4 of a turn in geometry is 90 degrees
90º=1/4 turn 360°= 1 Full Turn 180°= 1/2 Turn 270°= 3/4 turn
It is: 1/4 of a 360 degree turn
4/1
It is: 1 to 4
Its a small exhaust probably 2 1/4" single with glasspacks. But I think they dub the sound in.
you turn all of them, th red 2 times, the green 3 times, and the blue 1 times
