Awesome news. Did he state why you needed a new balancer?

The shop manager suggested a new harmonic balancer when I showed him all the parts I had bought and asked if there was anything else. The truck is twelve years old and these pulleys have a rubber hub. Once, I had one slip on my Isuzu Trooper and when I did the timing belt it caused lots of problems because the TDC mark was wrong.

So, I have been following this thread (not quite to its entirety), and I'm concerned that I let this go for too long. If I am already seeing oil pressure drops (just started last night--parked it) and experienced some mild shaking/rocking at highway speed, am I too late to go trough the repair process? I had a 5.4L Lincoln Navigator that showed symptoms at idle, but never at speed.

Hey everyone this forum is great. It has given me the confidence to get this job done.... but I think I have a problem. I have attached a picture of my phasers are they in the correct position? The keyway on the crank is at 12 oclock. I have attached pictures. Should I move forward withthe chains or figure out what's wrong with ther placement of timing mark on the passenger side cam.

Need clarification. Have you 'just started' your timing job OR are you re-installing chains/phasers. If you just started - the marks on chains DO NOT align with timing marks on crank / phasers every revolution. In fact they align properly only once every 61 revolutions of the crankshaft - then the engine is on the opposite 'stroke' due to it being a four stroke. It takes 122 rev's of crank to align marks again on same stroke. /Least Common Multiple 21 crank teeth, 42 phaser teeth, 122 chain links/ ( BEWARE ). Try to get your pics fixed and we can be more help.

Reinstalling chains... pics came from my phone is there a better way?

I don't know what is going on with that Phaser - But if the marked chain link is straddling the dot on the crank sprocket - it looks like the two colored links are not equidistant from the single marked link.

Definitely, the "R" is too far to the right - as can be seen by the cam lobes.

^^^^^^^' looking a little closer - perhaps if the crank 'keyway' is at 12:00 o'clock - perhaps the Phaser would move that far forward. Seems a lot for the 2 to 1 ratio, but I'll concede.

I prefer to have the crank dot at 6:00 o'clock instead of 7:00 o'clock.

agreed that it doesn't look right..... pretty sure the phaser is on correctly but now I'm thinking I need to buy a new bolt to be sure. .. if it is andvanced anyone know if i can put old tensioner and chains on to rotate till that cam lines up lock it down.... take that chain off and rotate the the rest to proper time again? Or is that too much to do with all the rollers in still.... I didn't pull rollers which i am trying not to do but now i run into this lol.


I'm thinking diagnosis is that phaser has advanced because the retention pin was not attached and fell out when old phaser came off.. can anyone confirm?

??? If you're talking about the alignment pin in the phaser that orients it properly to the cam --- I don't think so. The cam is at full advance (out of the box) and the 5th finger appears to be pointing at the "L" - which would be correct positioning for cam to gear markings. Cam lobes (and phaser) appear to be rotated clockwise (normal operating direction) a little too far. Your other photo did not come through but you stated the 'Keyway' is at 12:00 o'clock. (That should put the crank 'Dot' at about 7:00). Assuming the Left bank appears similarly too far 'clockwise', I would rotate the engine counterclockwise (backwards) a few degrees - approx. 10-15º to put crank dot at 6:00 o'clock, then check things out. Its much easier to lign up the single colored link(s) on bottom with crank sprocket at 6:00 o'clock.

Then if you need further verification, you can 'count chain links'. 30 Links from (but not including the colored link straddling crank dot) up to (but NOT including or straddling) the Cam timing mark --- BOTH ways, on BOTH sides. Then it's correct.
