Hi! Just a tip that may enlighten you on this one. Used to work on one myself, 3 bolts may refer to the top aircleaner case. 8 bolts for the valve cover itself. You will need a size 12 socket to remove this. Hope this helps and good luck!

    I see, Its gonna be the nuts you have to deal with. There are nuts hidden below the intake manifold. Try to touch it first with your fingers so you'll know where to access it. Please make sure that the engine is cold before touching it to prevent injuries.

I NEED TIMING CHAIN DIAGRAM FOR VQ20 NISSAN SERFIRO 1999


Instructions
  1. Remove Your Timing Chain
    • 1 Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Altima is 60,000 miles.
    • 2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.
    • 3 Drain the cooling system and disengage the negative battery cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.
    • 4 Disconnect the engine undercover, vacuum and fuel hoses, harness and connectors, drive belts, power steering reservoir, alternator and bracket, upper radiator hose, air duct, front exhaust tube, intake manifold collector supports, collector and exhaust manifold and the distributor.
    • 5 Prop up the oil pan and take out the front engine mounting, the valve cover, camshaft sprockets, cam bearing caps, camshafts, cylinder head bolts (reverse the installation order), cam sprocket cover, upper chain tensioner, chain guides and chain, idler sprocket bolt, cylinder head, intake manifold and cylinder head gasket and the steel oil pan.
    • 6 Place a steel cutter between the steel and aluminum oil pans. Slip the cutter around the oil pan's edge. Disengage the steel oil pan, baffle plate, oil strainer and the front tube.
    • 7 Secure the car on jack stands and place a seal cutter in between the oil pan and cylinder block. Slip the cutter around the oil pan's edge.
    Install Your Timing Chain
    • 8 Reconnect the crankshaft sprocket, oil pump drive spacer, idler sprocket and lower timing chain. Position the lower timing chain on the sprockets and line up the mating marks.
    • 9 Rub on an unbroken bead of liquid gasket and put in a new front cover and oil seal. Secure the bolt at 105 to 112 foot pounds (142 to 152 Nm).
    • 10 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.
    • 11 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.
    • 12 Refill the cooling system and add clean oil in the engine.
    • 13 Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.
Tips & Warnings
  • Procedures for replacing timing chains in Nissan Altimas vary slightly depending on engine size.
  • Make sure the new timing chain matches the chain you are removing.

How do i change the thermostat on a '02 rodeo V6?


Hi, you have to start by removing the fuel pump fuse and start car, when it dies try to start again, no more spluttering just cranking, the fuel system is now depressurised. You can now disconnect both of the quick disconnect fuel lines at rear lower section of inlet manifold this is hard to get to some access this by removing the EGR valve so you can get your arms down there watch out for sharp edges of manifold. You dont need to take the top section of the inlet manifold off but will need new lower inlet manifold gaskets to head. Once manifold is off block all intake ports with rag or put tape over ports to stop dirt and stuff falling into ports while continuing to work on the coolant pipes below to get to thermostat. Undo only 4 long centre bolts and the 4 nuts, one in each corner(no.3 in picture).

Head gasket is cracked


there is no connection betwen the doughnut gasket on the outlet of the exhaust manifold and the head gasket. The head gasket is under the cylinder head and does not crack. It may blow due to compression pressure leaking between the head and the block.
Are you sure you don't have a brkoen stud on the exhaust manifold where it mounts to the blcok? Known Nissan isue. The bolts don't stretch when hot and eentaully they all break off. Newer studs do stretch.
