Re attach chain using master link. Ensure that there is one metal tab in the center, one on the open end and then the clip. Again, note the orientation of the clip. Closed end towards the exhaust.

Instal new half moons (2) in the back of head. If you forget these, you will leak oil immediately from the back of the head and will have to remove cam shaft cover, gasket and intall.

hmm, not that I remember either. Perhaps my evil twin Tifosi?


If I may add to this excellent post, when re-tensioning the chain ofttimes the spring is not strong enough to fully tension the chain. It might need a little nudge with the pry bar to make sure the chain is tensioned. You don't need to try to stretch the chain, just remove most of the slack.

Fill with new antifreeze through the overflow bottle. S4 self air bleeds, so run the engine a bit and fill as needed to the correct level.

That's it. It's a great, satisfying feeling.

Have some fun.

Excellent write up and pictures!!!

It should go without saying that the oil should be changed if you do the head gasket, The Anti-Freeze too.

Master Link

Vintre

I think your master link is installed incorrectly. The photo shows two plates on the front and the clip on the back. There should be one plate in front and one plate in the back all held in place with the clip.
The clip is not designed to carry any load just hold things in place. I would hate to see all of you work be for not, along with the new valves and other parts needed if the chain breaks.

I'm diggin' it, thanks for sharing.

Yes, I claim the cam cover tightening sequence graphic.

One small note of possible worth:
At times the VVT pluger that goes through the cam cover can be real easy to drop out/misplace/lose/forget during removal storage and reinstall.

If leaving it actually in place in the cover, a small slip of vacuum hose over the protruding exterior end pre-cover removal will prevent it going anywhere until you are done done.

'Course while things are apart it offers as good a time as any to replace the o-ring that seals that plunger from leaking oil down the front of the head.


Oh, the dunno what it is 27mm wrench fitting sensor at the top back of the head?
Overheat warning lamp as found on the monopod.
Not present in the dual pod engines.

I am glad that this thread will be helpful to others.

Tifosi, thanks for the cam cover bolt tightening sequence and letting me know about the over heat sensor (corrected above).

DDS, I am pretty sure I caught the master link but just in case, off I go to the garage to check.. If I did it correctly, I will post a correct picture, because I don't want anyone to follow something that is wrong.
