Crank center bolt

[hahnmgh63]

Not 100% sure but I think it was 16 links. I've got my Cam covers back on now so I'd have to pull them to check.

[AndyRS6]

I would appreciate your checking. Back to service position tomorrow. Thanks.

The distance between camshaft markings -A-and -B-must be 16 rollers of the drive chain. Position rollers 1 and 16 according to
illustration.

[AndyRS6]

Is that for left or right side? Cuz I need left one and i believe it should be 15.
Also, bank 2 is left (driver) side, correct.

[mdegracia]

Just align the timing marks as shown and you should be all set. The number of rollers between the points is kind of irrelevant, either the marks will be lined up or they won't be.

[AndyRS6]

Thanks. In the process right now.

[AndyRS6]

Ok, I stumped, did everything by the book.
I have a question, when I opened valve cover, chain tensioner Piston was up, when I turn crank by hand Poston went down and never went up, so does the Piston works only by oil pump when car is running. Cuz now, as in the second picture I got big gap between pad and chain. Between links I have exactly 15 links. So looks like I'm link off, but still now sure if my chain tensioner stuck in closed position.

[mdegracia]

There will be a gap because the cam chain adjusters need oil pressure to adjust the shoes in both directions.
Rotate crank to TDC. Install the lock pin and set timing per that illustration.

Is there a way to remove intake cam without removing tensioner? Of not, can I reuse chain tensioner gasket.

Update:Finally started the car. Got rough idling and check engine light. Fixed check engine-problem with MAF sensor, ground wire was separated. Got VAC-COM, scanned the car to figure out what causing rough idling. Have two codes but no dashboard lights. Codes are :
Address 01: Engine Labels: 077-907-558-BCY.lbl Part No: 4D1 907 558 D
Component: 4.2l V8/5VT G 0003
Coding: 0006752
Shop #: WSC 02195 785 00200
VCID: 2F6D04D6BD3CF646D7-5140


2 Faults Found:
17983 - Right Engine Mount Solenoid Valve (N145)
P1575 - 001 - Short to Plus
16406 - Bank 2: Camshaft A (Intake)
P0022 - 001 - Advance Setpoint not Reached (Over-Retarded)
Readiness: 0010 1101

Timing belt was done with proper tools, so it cannot be the problem and checked many times for proper fit.
Can someone help me out with second code, how to pin point the problem.
Thanks.

The code suggests your intake and exhaust cams are not 'timed' to each other correctly. this suggests the cams were out and not reinstalled correctly. You mention a timing belt. Did you do tensioner shoes also or have any other ned to have the camshafts removed from the heads? There is a VERY specific setting for both the passenger and driver sidde heads - and NO they are not identical.... You can quickly pooch your engine if you mess this up. This is a tight tolerance engine, but the 1 tooth likely won't be critical as I know a number of people have had a tensioner pad disinegrate and after introducing that much slop in the timing they still didn't damage valves.

Nope

Can I reuse chain tensioner gasket?

Many have before. It would be suitable to use a new gasket, but if you don't have downtime on your side, you can look to reuse yes.

[Bigglezworth]

Just align the timing marks as shown and you should be all set. The number of rollers between the points is kind of irrelevant, either the marks will be lined up or they won't be.

I disagree with this statement. There is a specific number of rollers that needs to be counted as the alignment marks are different for the driver and passenger sides (drivers side is 15 links and passenger side is 16 links). The marks don't line up as well as you would like to make it idiot proof IMO. I've done this a few times and it does require double checking and counting each time to ensure 100% alignment.

[mdegracia]

The illustration shows the alignment. If the alignment is correct, you will only be able to fit so many rollers in the space. the gap between the adjuster pad and chain means nothing, it will pump up. The gasket can be reused if it was just installed.

Yes, i did tensioner shoes also. In this side top shoe was broken, before intake cam removal i mark everything and install back same way, count 15 links between marks. Cams and caps marks align perfect. Results-rough idling.

[AndyRS6]

so i reset timing and now i got this.


is that the way it suppose to be? can somebody confirm that
will try to put everything together and will buy new gasket tomorrow. hopefully will fix the problem.
Thanks for your input.
