I need to remove the intake manifold on my 2000 xk8, aj27. At this point I have the TB removed but not sure of the next steps. I believe the "elbow" stays with the manifold during removal. After research I think these are my next steps.

1. Remove and hoses and tubes connected to intake elbow.
2 Remove the two bolts holding the elbow to the support brackers.
3. Disconnect both fuel lines and electrical connections to fuel injectors.
4. Disconnect anything else I missed.
5. Remove the 10 bolts holding the intake manifold and pull the mainifold, elbow and fuel rails as one unit.

The purpose is to get to the leaking valley hoses.

All 99 shop manual does not address pulling the manifold and many of the write ups just mention "removed intake" but not much detail.

Thanks in advance for any help.

 

Yes, the elbow can be left in place, although some elect to replace the rubber seal (3) while things are apart.

The brake booster vac. pipe is detached by depressing the plastic collar on the union to the TB while gently pullling the pipe out (the locking mechanism is similar to 'push fit' plumbing joints).

Loosening the lower elbow support bracket bolts (9) will give you a little more wiggle room to R &R the inlet manifold:



Consider fitting an aluminium thermostat tower and a new water outlet pipe (AJ85885) 'while you're in there' if they're not on your list. Both are plastic, both can and do fail.

You may need a 'special tool' to disconnect the fuel lines. They're readily available, although I managed with a short piece of 15mm plastic plumbing cut along the length. Not sure if the AJ27 connectors are the same as AJ26?

 

See if this helps.
