TAMD74 Exhaust Manifold service

[Erik Forslund]

I plan to replace service gasket kit on exhaust manifold and need some tips in what to remove.

I guess:
* drain coolant system
* front connection to water pump
* all 6 fuel pipes to fuel pump
* fuel filter holder
* coolant connection to turbo
* main exhaust connection to turbo
* Black box for electronics

The question, can i leave turbo as is, or do I need to unmount both turbo and aftercooler in order to remove the exhaust manifold?

Any practical tips are appreciated since I plan to solve this by my own.

You can leave the turbo as it is but you have the weight of it plus the exhaust on the oil return pipe and the bottom water hose , unless you rig up a strap to support it , you might also find the manifold needs to be eased out the 4 studs that are screwed into the turbo plus you can dislodge the rubber O ring which is recessed into the manifold , I would glue it in the day before you fit it back on .
Might be worth having your turbo overhauled at the same time , I’m actually on with the same job this week.

Thanks, probably smart to remove a bit more than you need

do you mean glue on the motor side or on the manifold side? The damaged O-ring is the reason why i need to re-install the manifold

Glue it into the recess

I have now started to remove some items to get access to the manifold. Solved fuel filters, EDC-connection, black box, fuel pipes, turbo nuts.
Still some questions about two things, any tips are appreciated.

1. Turbo, when removing the manifold and since I plan to leave the oil pipes from turbo to the block, will it be pressure on them, or will the turbo be kept fasten to the air cooler?
If I need to remove the oil pipes, how should I best handle that? Check picture on turbo oil pipe, I don't know how to treat those.

2. Waterpump, since the turbo will be left, I will not have that much space on the manifold frontside at the water pump. I have removed the last piece, but wonder if it is possible to remove or flex the pipe a bit, and I don't see any other connection to remove. See attached picture and the schema on no 40, 41, 42.

Undo the pipe from the oil cooler then the 4 that secure the stat housing top cover and take that off then the pipe will come with it .
