I can't quite see what's going on with timing marks, but set the crank on TDC (remove no.1 spark plug and insert a welding rod or a long screwdriver down the bore as a guide) and remove rocker cover and watch what the valves are doing. Both intake and exhaust valve rockers have to feel loose and the dizzy rotor needs to line up with no.1 HT lead on the cap.
Once you do the above, the timing marks should be pretty much be lined up.

may be close but not close enough. thanks for the advice .

Have you had the camshaft sprocket off at any stage!

no not the top one. first time i have done a cam in this car.

make sure to slowely turn it over by hand 2 full rotations to see if its not hitting valves befor you try and start it.

id remove the plugs and if its 180 degree out then it will be top dead on marks on number 1 cilinder after 1 full rotation you poke a wire in the sparkplug hole and can then feal if it is top when markings line up.

Doh. I should have said that the top mark could be a half turn out, not the bottom mark.

bump. Took some photos to a mechanic but he wasn't much help. no point taking the plugs out. Its the top sprocket i am worried about "Not the bottom one". I just pay the top sprocket never moved when the belt came off.

well did you what i told you! once you done what i said in post 8 you fire it up and you soon know if it runs right or not.

English version. Your **Top Sprocket** is directly connected to the camshaft under the tappett cover. REMOVE THE TAPETT COVER. Observe Timingmark DOWN= T D C Firing no4 cyl both valves having clearance and rockers touching round end of camshaft lobes no 1 cyl at this point has both rockers on the pointy valve opening end of the camshaft lobes Timing mark UP= T D C Firing no1 cyl both valves having clearance and rockers touching round end of camshaft lobes no 4 cyl at this point has both rockers on the pointy valve opening end of the camshaft lobes

I checked for the timing marks on the bottom cam shaft sprocket
TDC Crankshaft can be TDC no 1 cyl or TDC no 4 cyl. Rotate one turn and ya **down** mark is an **up** mark.

Thanks for that. It looks directly opposite the timing mark. So must be first firing on number four. Ill take the rocket cover off. And see if i can figure it out.Thanks

You have the right idea but. If i use the pistons as a guide it will not help. The timing marks on the bottom sprocket are correct. Its the top sprocket i have to figure out. One tooth out can cause damage,

Put the belt on with the bottom pulley in the right place, top pulley opposite where it should be. Turn the engine over by hand 1 complete turn and everything will line up.

rocker first and last piston have to be fully open and fully closed when you turn engine over on crank with spanner 1 full rotation then the oposite valve has to be open and shot 1 and 4 . easy . nothing more easy then a 4 cilinder engine.

This what I would do. 1. Take belt off 2. Turn crank backward approx 1/4 turn. 3. Turn cam until marks line up and lock in that position. 4. Turn crank forwards until marks line up. 5 Refit belt 6 Turn engine 2 turns by hand and check everything still lines up.
Looking at your pics the can has turned (as I would have expected it to)when you removed the belt.

Correct. This means i would have to take the rocket cover off just like snoopy221 said. I can poke whatever down a spark plug hole, This makes no difference as i know the bottom sprocket is where it should be. As you know the top sprocket is confusing because the timing mark is sitting opposite to where i think it should be.I have turned the motor over by hand and it feels fine. But ill remove the rocket cover and see what should be touching is touching and what should be clear is clear. Thanks for your time. Motor is on the ground not in the car so that makes it harder to test.

Good advice here also However if you ever proceed from changing cambelts to adjusting valve clearances the understanding of piston pairs- no1 and no4 and no 2 and no3 cyls And how to set tappetts on TDC Firing-when the other pairing piston is TDC *Rocking* Well
Remove tapett cover and observe how pistons 2 and 3 are the same as 1 and 4 set valve clearances at TDC Firing

. but it shouldn't have turned 180 Degrees! IF It had moved it would have moved maybe 1/4 Of a turn!

good advice! That confused the hell out of me

Dude the REAL english version is ya. Didn't have ya camshaft on no1 TDC Firing when ya took ya covers off. IF You had aligned the top sprocket mark AND the bottom sprocket mark the top sprocket would NOT be the 180 degrees out it is. CAMSHAFT TURNS AT HALF ENGINE CRANCKSHAFT SPEED.

REFER POST #16 IN THIS THREAD. It'll make REAL sense when you have the tappet cover off. However the **Good Advice re turning bottom sprocket a quater of a turn. Is
Simply remove belt-disconnect top of engine from bottom Turn bottom so ALL pistons are halfway up and can NOT damage vlves when top is turned INDEPENDANT of bottom.

I do not know where it was, Like i said i pulled the bottom sprocket off and the belt came flying out. The white marks you see now are from me after put the belt back on thinking this mite save the hassle. But then looking at the top cam shaft i figured out that the timing might be out. If i Google it, It shows that the timing mark is at the top of the cam. So if i align that mark with the cam mark it should be bang on!. Is that what your telling me/!

I can see the bottom timing marks. Will try your trick tomorrow "POST 16
