Anyone ever had the inlet manifold off their 300 TT. I have an oil leak below it and due to access to pipes under the manifold being restricted, am wondering if the engine will need to come out.

no you don't need to take engine out. Fairly easy job as far as working on these goes. There just seems to be alot of pipes holding it down. Any idea where the leak is from?

cheers for the reply.. I am not 100% sure of the component layout but the leak looks like from around a rocker cover. It can be seen with the 2 intercooler pipes removed from the passenger side and look in below the manifold. It isnt a bad leak but after the car has been running for a while the oil must be going onto the exhaust/turbo as it starts to burn and smoke a bit but i want to repair it.

Are there any sneaky bolts as i have removed the 8 on top and can see 4 at either side. What about the two pipes on the bottom of the manifold they look a nightmare to get the 10mm head bolts.

I am gonna try to get it off tomorrow afternoon after work, I work on commercial vehicles and they are a doddle compared to the Z, access is a nightmare.

The only other thing is what are the small electrical components beside the spark plug coils...are they electronic injectors..as the connector terminals are all green corossion. I was gonna clean them all up upon removal of the manifold.

 

Cheers again....John Crisp

yes your right with the 2 pipes on the bottom - right asshole but patience you will pervail. You will need a new gasket to put the plenum chamber back on if you take off, also worth changing the PCV valves whilst off if they haven;t been done recently.

The other connectors you are right they are the injectors.

When you do the 6 bolts up in the middle make sure you dont over tighten them as i did and break the part underneath as it is only aluminium - never has been the same, got a new one but will get round to fitting it one day.

yeah access is a bit limited to the pipes but tomorrow i will go into work and finish removing it, then the rebuild haha..thats when the fun really starts.

Do u know if Nissan do the gaskets seperate or is it a full kit and the other parts u mentioned are they expensive.

Cheers
