Inlet manifold - Easy job?

jubbarelly · 23rd July 2014, 10:54

I've got a replacement inlet manifold coming for Chaggy.

How easy is it to take the old one off? Anything need to be replaced before the new one goes on?

Thanks
Jub

Don't bother with the wedge's, its not made of Airfix grade plastic, don't be afraid to manhandle the thing

and you dont need to remove the throttle body at all, unless your'e gonna clean it.

However you do need to be very careful with the plastic breather pipes

Have I GOT to disconnect the fuel lines?

Jub, there's nothing to it. Just squeeze the connector and separate the pipes. When I did it there was no residual pressure and no loss of fuel.

And they could test your patience

Oh, and when you put it back together dont bother with the 2 lower fixing bolts at the rear of the manifold, you'll see why when you try to remove them.

It may be worth changing the O Rings and seals that seal the manifold - they're going to be at least 8 years old now.
Here are the sealing items used on the inlet manifold:
O Rings - KV6 Upper Manifold
Seals - KV6 Upper Manifold

if you must have the car on the road immediately then maybe get the orings.
there is a very very small chance that you will need new ones.
the car will be undriveable if you have a manifold air leak. It will bounce between 600 and 2000 rpm.
its a very small possibility though.
keep rags handy to catch petrol when disconnecting the fuel lines. And do it outdoors. Don't want to burn your house down.

yep. Don't mess about trying to do it another way.
the worst that can happen is the rubber or plastic has deteriorated and the fuel lines break. But my motor is 13 years and 110 k old, and i take the manifold off without thinking twice. I too have discarded the two rear screws on the manifold.
you just need plastic wedges so you don't damage the manifold.
its not a difficult job.
