Re: need 2 no where timing marks are for 86 hilux 2188cc...
Hey NewK, Try looking under the Cam Pully If ya got the radiator out Its at the lowest point Fuunyist thing I ever seen but thats where it is. Heres a tip if ya radiator is still in the vehical Use a small mirror to help you see the Underside of the pully......................Tight Nutz, Donkuz.

Your timing marks should be on the belt. There are two single lines and one double line across the surface of the belt. Each of the single lines line up with the cam shaft and the balance shaft drive gears. The double line lines up with the crank gear. If I remember right, there is a small mark on the oil pump housing that the crank mark lines up with and the cam mark is straight up and there are 2 other marks on the cam gear that line up with the head.
You can find the timing mark on the end of a crank shaft by looking for an indented dot which marks top dead center.
A flywheel is balanced and does not need a mark. However if the wheel you refer to is a cam gear (one or two gears depending on how many cam shafts your engine has) look for 2 dots with a tooth grove between the two dots. A matching drive gear will have a single dot aligned with a tooth on the drive gear. When put together the single tooth marked on the drive gear must fall into the grove marked the the 2 dots on the cam gears.
If you are just trying to time an engine, the belt drive pulley mounted to the crank shaft will have a single indented line. The line can get filled with dirt so you can't see it. Wipe it clean and fill with grove with something to highlight the groove, as with a white or yellow crayon or a dob of bright paint. Associated with the belt drive pulley, there should be a metal plate with line marks spaced on it, with 0 degrees (top dead center TDC) marked on it, When the engine is running, using a strobe light connected to your number 1 spark plug you will see where the timing mark on the belt drive pulley is compared to the metal plate with the timing marks.
if you know where the timing marks are supposed to be the use the old method of cam/crank timing to check and adjust to where the marks will be. Remove no 1 injector and turn the engine over until no 1 piston is coming up on injection stop when you reach TDC. mark on flywheel of harmonic balancer. If there is valve clearance ot both rockers turn the engine another 180 degrees and bring the piston to TDC again. watch the rockers and if you turn back a few degrees or turn forward a few degrees you will see ( in the forward direction) the exhaust valve closing and at the same time the inlet valve will be opening. This is known as valve rock. As you move the piston bacvk and forward over TDC you will see the valve movement. set on TDC and check the timing marks with the positions indicated. Remove and reposition the cam shaft gear to achieve the correct mark alignment or pull the cam shaft out just enough to realign the teeth to the mark. At the most you will be about 1 tooth out. The pump timing will be out 180 degrees as you are setting the valve timing on the induction stroke and you will need to turn the engine 180 degrees to compression stroke for the pump timing marks to line up. the injection mark on the flywheel is what you are looking for and when it is at the correct number of degrees as indicated by injection / lightning flash sign then the marks for the pump should be just about lined up
if you can remove the timing cover and try to bring the engine using your hand with a tool by turning the crank shaft with the engine off and battery terminal off,to the timing marks. surely the camshaft and crank shaft sensors do have some marks. if it is diesel engine also the fuel pump has mark too. If you aligned the marks and are in a correct place then you problem is something else,If the marks are not aligned then you timing is wrong and try once more to fit it whilst in a correct place.
6 Cylinder petrol: Align crank(C) timing notch mark (1) to oil pump mark. Align cam pulley(L+R) marks(3) to cylinder head marks The cam belt has 3 marks, 2 lines and one mark that is actually a row of dots. Align the dots to the crank pulley groove mark(2) and align the other 2 lines to the cam pulley marks. Using a clothes peg to hold the belt to the cam pulleys works wonders to keep it in place while fitting. Please note the arrows on the belt and have them point in the direction of rotation - right to left side of engine W - water pump pulley I - Idler pulley T - Tensioner pulley.
If for some reason you need to realign the cams on each bank : Standing
in front of the car and starting from YOUR left , looking at the cams
you should see RE, RI, LI, LE on each of the camshafts.(R for right
bank, L for left bank, I for intake and E for exhaust) Right bank
camshafts are marked with one dot, left bank with 2 dots on the shaft
itself. To align the camshafts to each other each cam shaft gear has a
mark on it. Draw an imaginary line between the centre of the camshaft
and the centre of the pulley. The alignment mark should be between the
two along this imaginary line. The result will be that RI an RE will be
at the top of each gear. The same with the left bank.
thats why you line everything up BEFORE taking the belt off. Usually when the timing marks are "ON" the dowel pin or key for the cam will be at the 12 o clock position. Also if you have the valve cover off, both cam lobes for number one cylinder will be pointing down.and both rocker arms loose. it would be a good idea to adjust the valves also.
Hard to explain here... but I believe that car also has the balance shaft which needs to be timed as well. The camshaft has 2 lines which line up to the top of the head, and a "up" or "top" mark at the top. Crank is set to 0 degrees.
The crankshaft pulley has a hole in it, just above the key. It should be straight up and lined up with the mark on the engine.
The cam pulley also has a hole, and it should be lined up with the little v in your camshaft cover. Put the belt on, line it up, and turn the engine over with a wrench or socket, 2 complete revolutions. Everything should be exactly the same place as when you lined it up. If not, you are out one cog, and will have to do it again.
Make sure the cam is on compression stroke when you line it up. Both valves on #1 cylinder should be fully up... in the closed position.
