Check out this factory catalogue, might help. Schematics give you an idea.

thank you,

so i need to change gasket betwen cylinder head and camshaft housing - looks like i have to remove timing chain?

MSTACH

does anybody know if i have to re-set (re-tension) camshaft chain after removing camshaft housing to change a gasket?

Serge944

You need to remove the sprockets on the camshafts and the timing chain slips off. By doing this you lose cam timing. You need to reset it using factory tools:

Serge,

would you know which gaskets or sealer (parts #, loctite#?) i need to get when i am going to put it all together - camshaft housing?
And torque specs?

Serge944

This is the correct gasket maker for surfaces without a gasket. I even used a bit of it on the chain housing gaskets "just in case."



Here are the engine torque values:

Serge,
