I'm replacing the exhaust manifold gasket on a Nissan Altima and cannot figure out how to interpret the service manual diagram for the torque specs. From Google research, the bolt (the green arrow is pointing to) requires 29-32 lbs. but I'd like to understand this diagram before proceeding.

So - the bolt very top left in your diagram should be tightened to 51 inch pounds (i.e, 4.25 ft-lbs - not very tight!). The nut on the left immediately below that bolt should be tightened to 11 ft-lbs - over twice as tight, but if you just look at the numbers, 11 versus 51, you'd think that the top left bolt was put on tighter.

From the diagram, I would think the cylindrical thing is a separate part, which is screwed into the cylinder head with a torque of 14.7 to make sure it is fully inserted into the head, and then the short bolt screws into the end of the cylinder with a torque of 41.7.

I'm not sure if we should do the timing belt once more, however, we will be using the sentra service manual, and getting our torque values from there. I can't even find a haynes book for this thing, they were only published in the UK, I believe. But I really only need it for the cam cap bolts, as the head bolt values are in the owners manual (I guess nissan figured that it was all a person would need to replace their headgasket, if they chose to do it on their own).

I finally got the FSM, did the headgasket swap, and the 4th cylinder piston ring is pooched, so it's leaking still. But the valve seals are replaced and they are not leaking anymore (they literally slid off).

When taking the head off, we noticed that the timing was advanced on the crank by 1 tooth. So I reset it back to factory spec and it didn't hold an idle well. So I just put it back to what I saw it at when we took it apart, and it worked like it did before.

K9K engine repair manual. This is a manual on the engine mechanics of this Nissan model. Contains instructions and data on repair procedures. Includes exploded views of engine components, engine block, and cylinder head.

The Nissan K9K engine is a 1461cc engine that uses a timing belt and has 2 valves for each of the 4 cylinders. The firing order of this engine is 1-3-4-2. This engine uses high pressure direct injection diesel fuel. It is used in Nissan Amera, Cube and others such as Dacia Duster, Dacia Sandero, Renault Megane Renault Clio.

The mechanical manuals of the Nissan group show all the data on adjustment and repair of engines belonging to this group. In some cases, the manual provides diagnostic assistance using a troubleshooting chart.

This diagnostic table is compiled based on the symptoms that can be found in a car engine. The Troubleshooting Chart walks an auto mechanic through the inspection process of each stepper motor system, providing the data and specifications that must be followed to resolve a motor's mechanical problem.

This operation is labor-intensive and expensive. It is necessary to remove the camshaft and, accordingly, the timing belt. In addition, you will have to spend money on pushers (cups) of a certain height. But sometimes you can save money: some services modify parts to the required size by grinding.
