Default PLEASE check my timing before I assemble

Put in the pistons/rings/rods today. Put on the head. Torqued it down to spec. Put on new water pump. Put on new belt.

NOW:
I read around in "garage" of m.net how to align the timing belt marks. Most links were not helpful since they were not detailed enough to my liking.

So check this out:





DO I HAVE EVERYTHING SET PROPERLY?

We turned the motor with a wrench, everything seems to turn smoothly and without any hiccups. According to what I've seen on M.net garage the two "I" and "E" should correspond to what's on the cover, and the crank mark/dip should correspond to the arrow on the block.

So can you guys please confirm if this is correct or tell me if It looks off before I throw the motor in? Just super paranoid about this and wanna make sure its set up right before I throw on the covers and re-install the motor.

TIA

It's really hard to tell from the angle of the pics.

Damn it, I was afraid of that. I'll take some more from a dead on angle.

Those marks on the gears though: should they line up with the "y" on the cover or point straight at the "e" and "I"?

I've always lined them up with the mark on the plate. You also need to count the teeth on the belt between the gears. IIRC there should be 19 but you might wanna double check that.

I was thinking that too BUT you see the teeth with the markings? follow the tooth on the gear back to the mark on the engine.

Looks lined up to me however i'm only going with visual as i've never actually torn my engine apart or done timing on it.

Looks good to me too...

Is there any other ways to check the cams without the back cover in place??
I see people without that cover installed and unsure as to how they got the cams in the right TDC position to begin with.

check this with others the 99-00 dont really have a way to change the ignition timing (i believe). Not sure if this will help you out but worth taking a look. I cant send the full workshop manual for you today. Unfortunatly my net is being way too slow

Looks good. If the crank mark is lined up, and the two marks at the top are aiming straight up with 19 belt teeth between them, you're gold.

Oh so that's what it is. Levnubhin was partly right then, except its from mark to mark including the teeth on the two marks.

In that case, yes the two teeth up top point up, and yes there is exactly 19 teeth on the belt between them.

Thanx for all your help guys

yeh no good. This wifi is junk and im having a hard time getting it to work properly but basically what he said ^. But i am going to manually type out what it says any ways. Installation (all models)

1) Position notch on crankshaft sprocket to 12 o'clock position (aligned with mark on oil pump) Align timing marks on camshaft sprocket(s).
2)Install timing belt tensioner spring with damper rubber closing face away from tensioner. Temporarily secure the timing belt tensioner with tensioner spring fully expanded (not sure if this applys to us)
3)Install timing belt around crankshaft sprocket, then working in a counterclockwise direction, route belt around idler pulley, camshaft sprocket(s) and tensioner pulley. Ensure there is no slack in belt between crankshaft sprocket, idler pulley, and camshaft sprockets
4)Temporarily install the crankshaft pulley boss and bolt. Rotate crankshaft about 2 turns in direction of normal engine rotation. Align timing belt pully boss mark with tensioner set mark for correct timing belt tension adjustment
5)Holding crankshaft stationary remove the crankshaft pulley boss and bolt. Ensure the crankshaft and the camshaft timing marks are still alingned. Loosen timing belt tensioner lock bolt to apply tension to timing belt. Without moving tensioner, tighten tensioner lock bolt to spec.
6)Install crankshaft pully boss, and final tighten bolt to specification. Rotate crankshaft 1 5/6 times. Camshaft timing marks should be aligned with marks on rear cover and the crankshaft pulley boss locating pin should point straight up. If timing marks are not aligned, remove belt realign all timing marks and repeat installation procedure
7)check timing belt deflection with 22 lbs of pressure applied to belt. ensure timing belt deflection is .35-.45'' (8.5-11.5mm)
8)To install remaining components, reverse removal procedure. While installing valve cover gasket, apply light bead of silicone sealer to 6 corners where gasket meets ends of camshafts. Tighten all valve cover bolts in the correct sequence.

Ill try and post a complete pdf diagram of how to do timing

What I hate is holding the camshafts in place with a cut valve cover. I thought that was the main benefit of cutting the valve cover, but I'm pretty sure it's impossible, especially if you want to be real precise with the line up.

If you look closely, the marks on the sprockets aren't actually lined up perfectly with the teeth, makes it easier to know that you're supposed to count the one touching the sprocket when counting your 19 teeth

I know this is old. I just followed all the advice here. Could you check the pics in my thread. I think it is spot on based on the info above.
