remove the rocker cover and the timing marks are on the back of the cams ,on the end are two slots one on each cam ,use a flat piece of metal to lock into place with teh valves on NO1 cyl pointing upwards and outwards and no1 cylinder at the TDC find this by using a screwdriver down the plug hole ,right er indoors waiting to go to market if in any doubt please post a reply and i will answer it later today.best of british with it
There is a notch taken out of the rear of the cams, you have to remove the valve cover to see them, there is a tool you slide into the grooves to hold the cams in time, i made my own tool out of a piece of square steel rod.
On the zx2 the cam shafts over the valves have to be viseversa the nuges sould look different on both like one nuge sould be up one and directly across from it should be down make sure when you looking at the front of the engine that there is groves on the right of cam shafts, you should be able to fit a flat bar an a flat piece of metal in there to keep it aligened as you put the belt on as you look at the bottom gear behind the passanger tire there is a incrament on it that mark should be at 12 o clock using the gasket from the oil pan as the starting point sence the oil pan is at a angle make sure the incrament on the gear is at a 90 degree angle from the gasket on the oil pan put the belt on with out any thing moveing its easier to put the timeing belt on with it being on the bottom gear first and then puting it on the top two with out moving the cams or the bottom gear once on remove the metal piece holding the shafts in place and put every thing back together . Note: if you have issues with the timingbelt walking off the gears, then you may have a worn or tapered lower timinggear. The early engines had a two-piece design that was prone to this type of failure.
cam shaft timing marks on back of cams ,two slots ,use a flat piece of metal to align .remove no1 spark plug and drop long thin screwdriver down it to bring piston just below tdc,then align cams so both cams are on the rock (valves closed) with knob on back cam aligning with pick up sensor left side between lobes.then bring piston up to tdc and fit belt.turn engine over twice with socket on bottom pulley to make sure no valves clear pistons.Remember to remove flat edge from back of cams i didnt last time and bent my home made tool
Stage 1 = 15Nm Stage 2 = 40Nm Stage 3 = Plus 90 degrees or quarter of a turn. Good tip is to mark all the bolts after initial torque setting with tip-ex , i.e. all to the front of the car. When you finish they should all point towards the timing belt. This is also a good way to make sure you don't miss one or tighten one twice if you are distracted since it is not a torque setting. New bolts should be used by the way as they are stretch bolts. Timing of cams - remove cam cover and you will see a slot on the end of the cams. Opposite end from belt. You need to slip a piece of 5mm flat bar or a long 5mm allen key into then so that the bar rests on the face of the head. Engine should be a tdc. cheers John
The cams have a notch in the back of them (facing driver's side) in which fits a flat piece of steel to lock the cams in place. The notches are not exactly centered on the camshaft, meaning that it's impossible to set them 180 degrees out, because then the flat piece of steel that is supposed to be inserted to lock the cams in place simply won't fit because the top of the cylinder head will get in the way. I highly recommend getting a Hayne's or Chiltons manual if you don't already have one. It should explain this process under the Timing Belt Replacement instructions. The cam lock tool (that flat piece of steel) can be purchased at ZXturner.com: http://zxtuner.com/product.sc?categoryId=23&productId=191
