Right here is pics... I Am 360 Out on the crank..Struggled Got Gammy Wrists....But if this no good can get out there tomo...It was getting dark Too.    First one is the 2 oclock mark on aux crank pulley

That doesn't look right to me. TDC on the crank, and a cam timing mark lined up, yet the intake on No. 1 is open.

Is the crank mark correct   2 oclock on the aux belt pulley

We need to confirm no1 is at tdc

I agree is that the correct mark on the aux pulley 

[JamesV6CDX]

Yes but as you say it can be 360 out, crank rotates twice for each cam rotation from memory?

It is james.. i was on a 3/8 snap on ratchet trying to turn the bleeding thing over by Hand.

Inlet is about to open to let fuel in...But im not happy with the crank mark..

In daylight will get aux belt off and do the job proper Along with timing belt cover

You are right that a four stroke crank turns twice for each turn of the cams but - The cams define whether the crank is on a firing stroke or not so no - you can't get it 360 degrees out.

[Steve B]

Proper nailbiter this one! I'd have torched the bloody thing days ago Good on you for persevering

Its gone too far to walk away..... I cannot except that Mechanical/electronics can beat the human brain... The show goes on. 

[JamesV6CDX]

If the pulley mark is at 2pm, and the cam marks aligned with the rear cover, I don't think you're 360 out?

We'll wait for Mr DTMs opinion on your pics and the position of the cam lobes, if it looks like we've ballsed up on that bank I will pop back to to help put it right

[JamesV6CDX]

I have done so many v6 top end builds, installing the cams and sprockets correctly and setting the timing is second nature. I'll be amazed if it's wrong

Yep surely if no1 is on it's compression stroke, you 'd expect the lobes all to face up, as the valves would need to be closed?

Also if the crank mark and cam marks line up, it must be at tdc, Steve can't be 360deg out? :-/

If we are confident something is definitely amiss here I will pop up with the cam locking kit to set it right.

If I have made a mistake here I'm likely to go very hard on myself. You know what they say about complacency and assumptions

[Marks DTM Calib]

I would say that the inlet cam is on the wrong mark. 

It matters not the accuracy of TDC on the crank, for this little test, near enough is good enough.

And as for timing on the cams, again not overly important.

[Kevin Wood]

Yep, with number 1 on TDC, or even near it, you are either at the end of the compression stroke (both valves closed, and will be for well over 90 degrees of crank rotation either side of TDC) or the end of the exhaust stroke (exhaust valve starting to close, inlet valve starting to open).

That picture doesn't fit either scenario.

Agreed

Well ive said it once so i will say it again. A Big Big thanks to All who Have gave input on this one.especially James who is the one doing all the running around.Im very Grateful And that is what makes this forum so great ..Its been a long road. 

James turned up here this morning at the crack of dawn To get his hands on the car And after a few hours work,Car was started up.
Now its running on all six And fault codes have all gone 

Just so glad to see the back of this problem 

[Marks DTM Calib]

And the route cause was?

[Steve B]

And the route cause was?

You know dam well what it was 

[aaronjb]

For the benefit of those of us without ESP?
