Timimg marks on a 2004 hyundai sonata 2.4 dohc

I just recently experienced the same problem. The timing is 180 degrees out. Unfortunately the only way to correct it is to take the engine apart again. Set the right hand camshaft to TDC by using the marks on the timing gear for that bank. The left will follow to the degree it can although you will have to manually hold the cam in position when you put the timing gear back on. Now you can remove the timing chain. The crank TDC indicator may not be right on but it will be close. Rotate the crank CW one revolution to the point the TDC marks are lined up. Now install the timing chain according to the instructions. The timing gears on the camshafts will only go on one way as the bolt holes are slightly off the extreme diameter of the gear. If you put the chain back on making sure that all the marks are proper, she'll fire on the second cylinder up. Not a fun job I know, but when everything works right, you do get a sense of satisfaction.

the pin is a line up pin for the balancer it does not hold the 2 together if the balancer is stuck you may have to use a puller to remove it

ENGINE: ok 3.2L but there are 3 V6 engines. 2 in 3.2L size.
6VD1 (SOHC) free running,
6VD1w (DOHC) belt snap should safe here. gears, put wrong IDK.
you didnt de-mesh the 2 cam gears , right?

6VE1(DOHC) 3.5L (not free running) in last DI form. last year.



the pump seized its bearings the iT CRACKED
the engines power can do that, !
ever heard of DOHC engine before?
and interference engine and how to deal with them?
seems not.


step 8 in cam belt off says
"WARNING Align the camshaft and crankshaft sprockets with their alignment marks before removing the timing belt. Failure to align the belt and sprocket marks may result in valve damage."

the experts say, all are free running but the 3.5L direct injected engine,but the VVT may have problems too, 2004?
never turn a VVT engine backwards.
i can not speak for if the 2 cams on one head the gears are set wrong, some heads on some engines can crash intake row of valves in to adjacent exhaust valve. (wrong assemble only)
be careful,.

the timming gear that the belt runs on has a mark (V cut in gear) to rear cover at about 12 o clock and crank pulley has timming mark for top dead centre, both cams have cut outs in rear that a special tool (camshaft stopper 5-8840-2592-0) locks into to hold cams in correct position, but can do without this, if the cam belt gear is off, the keyway should be at 12 o clock. the marks in the camshaft gears (dots) is for assembly of sissor gears to solid gears on camshafts that run together and they should match up only if you had this appart.

no.1 is timming mark

this is the locking plate tool

P0340 - Cam Timing

SYMPTOMS/CONDITIONS
of a mistimed camshaft system (all must apply):

1. Camshafts have previously been removed from the engine.
2. Engine runs rough.
3. Vehicle sets P0340 (camshaft sensor code).
4. Camshaft sensor has been checked with a known, properly operating camshaft sensor.

CORRECT:
The diagram in the manuals should show the timing marks on both cam gears to be on the blue timing chain links.

timing belt marks are as follows= crank at TDC marks are at 10 oclock the both cams marks at TDC are at 12 .oclock position marks are clear if you look theoil pump gear also driven by belt marks are approx 11 oclock position also marked thebalance shaft gear/cog must also be set to 9 oclock position when the b/shaft belt is fitted to hold theoil pump sprocket in its correct position remove the small screw/blank plug on side of block then use an 8 mm posi screwdriver insert into hole it should travel approx 60 mm to engage if not rotate pump gear 360 degree till it does locate fit main belt from crank anti clockwise to cams then tension same with b/shaft tensioner make sure you torque all bolts correctly any more info req'd come back hope this helps ?

DONT MESS WITH THE DISTRIBUTOR, JUST REPLACE GEARS AND TIMING CHAIN ALINE BOTH CRANK AND CAM GEARS DOT TO DOT CRANK GEAR DOT UP AND CAM GEAR DOT DOWN.

If you look behind the cam gears you will see a little nipple or indention in the metal baking and in the cam gears there should be a little hole line the two of them up to have the cam gears lined up. On the crank gear you will have a little notch on the back edge of the gear and on the block you will see either a notch or a nipple on it at about 1 or 2 o'clock line them up. Put your belt on, sometimes you have to turn the crank counter clockwise one or two notches then put the belt on and turn it make clockwise to get all the slack out of the belt. This should get it right in time.

never done one so i dont know where they are,didnt you paint the gears before stripping??never mind just do this ,remove rocker cover first ,then no1 spark plug.use a long thin screwdriver to watch piston move to TDC then back off a bit and turn cams ,look for slots or a grove on back or front of the cam or two recesses in the camshaft retaining caps jus in case the timing marks are on the cams,then with the valves closed on no1 and the cams have the largest gaps between valves and cam lobe ,bring pisto up to TDC fiot belt and turn engine on a socket and rachet on the bottom pulley twice to ensure the vaves clear the pistons before you try to start
