But yeah hopefully updates later today.
I also want to check to make sure intake and exhaust cam gears are on correctly. So please post a picture of the timing correct, and what the lobes look like.

I could be wrong (if so I'll be tearing down my motor) but the VVT cam gear will only lock into the cam one way. I was just installing my timing belt last night and I was worried about getting it on the wrong spot. So I turned the cam gear 360 degrees and it would only drop into place one way.

Since the gear itself has to stay in the same relation to the exhaust and crank gear, the actuator has to locked to the cam itself to move it separately from the gear. If not, the cam would just flop around.

The saga continues:

So 1st thing I do is test the actuator: put 12v and ground to it and it actuates perfectly. So that's not it.

Then I pull the cover off and take a wrench to the Intake cam: it TURNS counter clockwise (when facing car from front) AND THEN LOCKS. Can't turn it back clockwise.

I thought it was supposed to be always locked when engine is off?

So I think "this is it, it was probably stuck in that position and should be fine now.

Throw everything back together and start the car: same crap: runs like poo, uber rich, billowing smoke everywhere.



So I take off the cover again, AND AGAIN THE STUPID CAM TURNS BACK WHEN I TURN IT, AND LOCKS IN PLACE.

This can't be right??!!11??

So I pull the timing covers off this time, match up the crank notch to the notch on block perfectly, verify for that cyl 1 is at TDC, and check the other marks.

They look perfect:



So now I'm scratching my head.

The only thing I can possibly think of, is the intake/VVT cam gear mechanism has crapped out or something, and doesn't spring back and lock like its supposed to.

Or is that normal?

I'm clueless on what to do next aside from swap out the intake cam gear.

Cams are pointing directly opposite of one another, intake to the left exhaust to the right.

I notice that on the intake side the lobes are pointed in a different direction on your picture and mine

Notice just past the wrench on the exhaust side my lobes are pointed up when on yours they are pointed to about the 1:30 position.

Edit: wait, they are pointed the right way in some of the pics and not others... Is the top pic done with engine at TDC?

lol

nope that top one was just a shot after pulling the cover.

the other 3 are at tdc

*edit: so it looks like I did set everything correctly.

And yet here we are.

Anyone know if the cam is supposed to be locked with engine off or ...?

locked : cam won't move without the cam gear moving.

unlocked: cam moves counter clockwise like 30* then you can hear a *click* and it no longer moves in any direction. Its completely locked with the cam gear.

VEE VEE **** man

I never noticed that on mine. Ok. So let's think about theory of operation...

When no oil pressure is supplied to VVT assembly on cam gear, it stays locked. When oil pressure is applied it advances? Is that correct?

If so, perhaps something causing VVT to advance at idle. (Or basically in all conditions)

What things could cause this?

bad oil control valve. and mine seems to be perfect, at least it opens/closes fine. just checked it again.

also the passages in the vvt block look clean and nice. nothing stuck or anything

It opens and closes but how does the valve seal? Is there a gasket or o-ring in there perhaps? The valve may be closing but if there is an o-ring in there it could be blowing the o-ring out once oil pressure gets high enough.

So you're moving the gear back. As in every time you've popped the cover off to check things after running the engine, it's stuck fully advanced. I think it's supposed to lock back in place, and it sounds like it isn't. (Could be wrong.)

Sounds like I'd try your brother's spare parts.

Exactly. Either the cam gear mechanism is screwed or the oil control valve.

If its neither of those two, then I give up

If you have another valve cover with VVT on another long block, swap that over temporarily to see if the problem goes away.

Just found this website... seems pretty useful for parts breakdown...

so my dad stops by

says lets open up the vvt gear/mechanism

screw it, lets do it

this is what we find inside:


I have no idea what those stupid idiotic retarded pieces are, but they are not from anything within the gear itself. and obviously are not supposed to be in there, jamming everything

So either someone has already been in this thing (likely, since we found marks of it being taken apart/ re-assembled), or this was in the oil and got fed up to the gear through the channel.

ugh

so now after thoroughly cleaning everything, we re-assembled the gear and it actually slides back and forth smoothly, like it was intended to, so that's cool. it now also "locks" in place like its supposed to.

so we throw everything back on, crank the car, crank the car, crank the car, for ages and it just WILL NOT start now. No matter what.

I'm getting ready to set fire to it

Going to rip the mechanism back apart and see if something is still out of place. Again.

I am starting to have a deep hatered for this friggen engine.

its still showing only like 85-90kpa vacuum on startup. that can't be right. it must still be "advanced" when cranking.

I will attack it again tomorrow. if I don't set it on fire first

Try a different VVT actuator.
