Timing issue

[420aNEWB]

all the points on my timing belt mark except that the dowel pins are in opposite mark they are facing down.

So redo the timing belt install so the dowel pins are up... There's a reason why the dowel pins are facing up in that picture.

Did you time the motor with them up or down cause they need to be faced up. also what do you mean by they are down if you time it correct it takes 6 complete hand turns i think to bring it all back to were they need to be.

From what the manual says, it takes six complete turns in order to re-align the timing marks. I would definately take the time to make sure it is aligned correctly by removing the lower (timing) cover behind the pullies, to make sure all timing marks are aligned.

Since the starting position is random, the correct wording is it can take up to 6 complete rotations before all the marks line up.

With the cam dowels facing down your not at TDC cylinder 1.

If I read correctly what the original poster said, he said all the marks are lined up except the dowel pins are facing down. If the timing marks are lined up on the crankshaft sprocket/ plate, oil pump, and bs belt that would put cylinder 1 at TDC.

Yes, cylinder 1 is at TDC, but the cam position is "180 out".

OP, take the belt off and rotate the crank 90* so the pistons are all low in the cylinders. Turn the cams until the dowel pins are facing up and the marks are aligned, and bring the crank back to the timing mark.

At that point, all your marks should be properly aligned (assuming the BS and oil pump are currently correct).

Which actually makes the engine at TDC cylinder 4 since the cams move at half the crank rate and cylinder 1 and 4 are 360 degrees apart.

If the belt was put on this way, there shouldn't be any chance of interference with the valves and pistons turning the crank so there isn't any need to take the belt off yet. I don't remember all the different relationships when you consider the 3:1 ratio of the oil pump gears to be sure that the marks might not all line up correctly after additional rotations of the crank. Worst case you have to rotate the crank to get the cams and crank marks aligned and then redo the belt to get the balance shaft in correct phasing, assuming he still have balance shafts.

There's marks on the cam gears on both sides, I'm thinking the wrong marks were used when the timing was set.

hmm i shall rotate the crank today and see if the dowel pins align up and match the rest of the aligning points

It should be safe to do so but how about providing some background on how you reached this point.
