Haven taken best part of Sunday to remove the intake manifold and the heads. What a horrible fiddly job!!!!

In order to replace the head gasket.

 

Is it worth replacing the valves with uprated ones, and the injectors, As checking the condition of the injectors on removal, they all seem to be corrided, and brittle.

 

When removing the parts, under the intake manifold, found it bloody hard work to get to most of them. is there anyway of bypassing any of the pipes to make installation easier.

no its not worth replacing the valves, these are made of a very strong metal known as iconical, or something like that :p

 

replace the injector connectors, and clean the connections to each injector, it can make a massive differance to how the car will run, if they are in a bad way

 

if you mean all the water pipes, then you can do a full upper intake bypass, by directing the coolant to each turbo rather than all the fiddly hoses under the intake

 

do a search on how to, as its difficult to explain by text

 

cheers

I had my injectors cleaned, wasn't cheap but at least I know they are all atomising properly now.

Bugger, I paid nearly double that ! However, they did replace all the O-rings, which cost about £50 from Nissan.
