Intake manifold sequence

[Guest]

Hello

Does anyone know the intake manifold tightening sequence?

I could not find it in my manual

Thanks

I don't think there is one, just work round them gently, tightening each bolt a little at a time rather than completely tightening one bolt before moving to the next. This has always worked for me.

Found this up in the Service Training Notes ;

Tighten the inlet manifold to the left-hand head.
Tighten the inlet manifold to the right-hand head.
Failure to observe this procedure may result in the manifold fracturing.

(No experience of the task myself though)

The sequence only applies if you have removed a head, in which case one head is tightened last after the inlet manifold is tightened. This allows the heads to be pulled up square to the manifold faces.

If heads nave not been disturbed there is no particular sequence.

Hello
Thanks for the input. I will work from the center out using a cross pattern.
I'm going to put antisieze compound on the threads and hylamor blue on the
gaskets

Thanks

Apologies, reading again this is the applicable scenario

Don't I just know it. I have just done this tonight, wish I read this before hand. I tightened both heads and manifold equally in 3 stages. The last bolt on the inlet on the last stage of tightening stripped... I'm hoping someone can helicoil it without removing it - it's a lower one with good access.
