Is it possible to remove the rear mani while the motor is in the car? I recently discovered i have an exhaust leak pre turbo on my rear manifold..... which explains my lack of boost, and why my car sounds like a tractor. If anyone has removed it while it was in the car please tell me how, as i really do not want to pull the motor.
Sure
Remove the turbo. The remove the heatshields, then the manifold.
Some of the bolts are going to be a bitch.
Are you sure your leak is there? It is uncommon for the rear manifold to leak.

Its an aftermarket mani, had a.crack before.... Welded it thinking it cracked again
go back to stock
I've got a leak there too. Previous owner broke the studs off the EGR hole and JB Welded an EGR blockoff there. It blew off. Now it's just a hole that's covering my engine in soot.
In my research it's possible but a huge pain to remove. Gotta get the car way up in the air if you want it to be remotely easier.
you can weld that shut while the precat is in the car. Mine actually broke off, so I just welded the hole shut where the pipe went into the precat. Only had to remove the rear intercooler pipe.Quote:

He doesn't have turbos lol.. Just take it out, should be way easier than the TT cars. Only way it can crack is if your motor mounts are bad and your downpipe/headers are all one piece with no flex section.
Great to know. I had a shop quote me but they were worried about welding on the precat due to heat concerns. I think they were afraid of cracking the precat.Quote:

It is admittedly pretty hard to see in your sig. I'd hope that since you mentioned the turbo it would be fairly obvious it has turbos though :p
I've had the rear manifold partially off while the engine was in the car. It's definitely removable.
Well its currently the least of my worries, Monday I lowered it, installed exhaust, adjustable rear control arms, and my front motor mount bracket. Everything went ok, took it for a test drive, that's when I found ou the mani was leaking as was my dp... forgot to buy gaskets (have them now, just not in) so I go to head home from my buddies shop get on the highway and give it some gas, shift 2nd to 3rd.... big backfire right as I look in my mirror all I see is smoke..... I literaly stopped traffic it was so bad. Fml at this point, I limp it back to the shop coolant in the engine bay.... too late to look at it. Next day I decide to take a look at, my oil leak.... Oil cooler has been deleted, 2 plugs to block off the lines both leak slightly, I pull them out, Teflon tape them and go to put them back in.....and strip one out, after am hour at least we get it re tapped and pluggedno leak.... Time to go home at this point. Next day (today) get there after work, and tear out intercooler piping to find out I have oil in my rear turbo.... So yeah sounds like forced upgrades.... Did get the coolant figured out all my small coolant houses decided to loosen up at the same time... But yeah time for bed....put in 36 his in 3 days working on cars ha.
