Gasket Replacement, Q. About Turbo Removal Off The Rb25det Neo,

[ifixedit]

HI, guys..

I am having a exhaust leak and investigated it a bit more and have some questions about removal of the turbo and it's difficulty.

So I need to replace the gasket from exhaust manifold to the turbo (the T3/T4 gasket I think its called). sadly the bolts were loose and destroyed a corner of the gasket as to why it's leaking exhaust.. I could simply buy a new bolt and tighten everything and hope for the best but would like to do the job properly..

I have already removed the turbo heat shield, exhaust head shield, removed the intercooler pipes, and intake pipe so exhaust side is open and clean to work with. I did this thinking the exhaust leak was coming from the exhaust manifold.. but mistakenly I noticed 1 bolt missing off turbo and another 2 are loose enough to remove bolts with my fingers.. the 3rd bolt might be loose have not really cared at this stage seeming the others were loose.

I have ordered a new gasket and will wait for it to arrive before continuing this job.

so

I want to know while replacing the gasket can the oil/water feeds and exhaust connection stay attached to the turbo?

i mean, is there enough clearance to pull the turbo away from the headder bolts and slip in a new gasket without damaging the feed pipes and exhaust?

Or is best absolute practice to remove everything while doing a job like this?

thankyou.

You could probably do it leaving lines in place but it would be wayyyyyy easier to just take them off. It's only 3 bolts and a clamp.

Dump has to come off either way.

If you want a little piece of mind jump on sonic performance website and buy some inconel studs and conical lock washers. Also make sure you buy a good quality T3 gasket. I use genuine nissan as they are quite good quality.

Does any part of your exhaust hit the ground and does it have a flex pipe? I used to have a problem with mine coming loose and the issue was exhaust hitting the ground from having such a low car.

good advice.. thankyou. exhaust has been lifted to near invisible installation.. never hits the ground anymore. a soft flexipipe.. I am unsure if it has or not.. I know what your talking about just have not looked under the car will do tho.

during Road Worthy they were being asses about the custom Japanese install that came with my import. and tried all the tricks.. in the end I got it lifted and the pipe raised.. they did a good job..

Sadly I just brought a turbo gasket replacement. but if the dump comes off I might wanna order a gasket for that too!

I have to expect things like this, its an old car.. getting onto 15+ years now.. it's a imported car also and as problems arise I will fix them myself as long as it's not too major..

but in the future should I be looking for help doing a complete rebuild.. is there anyone trustworthy.. or even something I'd love to do myself with guidance..

It's something I would enjoy doing and would pay for time and great deal of respect for a expert on rb's to do with me.

the plan is to buy a rundown rb25det neo clone to whats in my car and rebuild that ready for when this one craps out.. this motor has 150k on the clock and it's higher then I wished for.

Turbo has enough movement to move with the lines on as there very long and loop

Just pry it down with a big screwdriver

Also you don't have to remove the dump pipe but atleast the fr pipe so the turbo can move down

I just replaced my manifold as it was cracked and left the turbo sitting there and it's was fine all bolted back up nicely and no leaks

Make sure you get oem metal layer type gasket to go between the turbo and manifold and you should have bought the genuine nissan locking tabs

They fold over the nuts when tightened to stop them coming loose

I removed the Studs, allowed minimal turbo movement.. slipped the new gasket in place, cable tied the turbo to strut brace, trolly jacked the exhaust pipe to lift turbo.. put the studs back in,

waiting to get some Bolts with locking washers.. all will be goodie!!
