Cylinder head and cylinder Torque check.

Thanks. That was my guess. But apparently dealer just keep a look and no torque check !!!!

I was following this post as well as i got first check done recently and was surprised that nuts were untouched ...
Chris I sent you a message.

The gasket compresses, effectively leaving the bolts loose and the gasket un clamped.

You need to remedy this situation, otherwise you run a very real risk of blowing the head gasket.

1st service also includes rocker inspection too. Easy to do while the valve cover is off.

Hi
Thank you for your feedback. I will revert to my dealer and keep you updated.

I'm certain you received this info from me in one of my emails I sent out with manuals. But here it is again.

All of the bolts need to be torqued. The numbers are the order of which you do them. It's confusing because their are two numbers on some of them. Like 1/7. This means you are going to torque it twice. The first time and the seventh time. So on that bolt you torque it to 22ft lbs (30Nm) then the seventh time to 44 ft lbs (60Nm),. Hope this makes sense.
Torque One to Six to 30Nm. Torque Seven to Twelve to 60Nm, then torque thirteen to fifteen to 30Nm
If you get the WEB version of the service manual, the torque specs are wrong. Only the paper version is correct. Above are the correct values.

Can anyone post a copy of the paper version?

Thanks so much.

I have more Q's
1) Where/How does one apply the "Extreme Pressure Lube"
2) Is the Head Cover Gasket reusable?

1 - This is fastener assembly lube, you can get it online.
2 - Mine was reusable, but I wouldn't reuse it more that once.

With regards to the "How" , Do you remove the fastener completely, coat in lube and torque as recommended?
Only asking as I've never used this before

If I were rebuilding the engine and replacing the head I would cover the bolt threads with a light coating.
But if just re-torquing the head, I wouldn't bother.
The fastener lube is designed to eliminate friction between the bolt threads so that the correct tension can be reached in the threads to achieve an accurate final torque.

Do you have the workshop manual?

I have a downloaded version. It says
"Tighten head and barrel bolts in sequence from one to twenty to torques detailed below (shown in detail in this chapter, section: 4.7.7)
Torque: Barrel Bolts – 25Nm
Torque: Head Bolts – 30Nm / 60Nm (Refer to 4.7.7)
Cylinder Head Bolts"

But my downloaded version doesn't have a section 4.7.7 for some reason

Check section 5.7 onwards, that seems to have the diagrams
