Taking Exhaust Manifold Off.

[Abo Bob]

It now looks like I have a leak in my exhaust manifold gasket. GRRR.

So, does anyone think I can remove the manifold without taking the lines of the turbo?

My plan was to:

1. undo cat at front

2. take off intake piping

3. unbolt turbo from manifold

4. Take manifold and shielding off, holding turbo in place

5. replace gasket

What do you think?

Depends, are your lines hoses/braided etc or std steel pipes. if steel pipes, no chance, if hoses then I'd reckon it could be done, I'd lower the turbo down and out of the way then it would be easy.

i'm with trident on this one.

will also depend on whether you break any studs in the process.

[Abo Bob]

Studs are all pretty new. Standard pipes.

Can be done - even solid pipes have some degree of flex, to allow you to move the turbo back away from the manifold.

[tridentt150v]

The good part about it is if you bend one and it snaps or fractures, you can replace them with braided lines and then you'll never have to worry about whether it can be done like that again...lol

For the 4 bolts involved + dumping your coolant, I reckon it would save time and swearing/knuckle grinding just taking the turbo off. Plus you will have more room to move the mainfold etc.

Just take the turbo off. Its 'only' 4 nuts and a couple of coolant lines. Adds another 30minutes on to the job IF you have the right tools.

At least then you can get in and clean up both surfaces correctly.

Its also difficult to torque up the exh manifold nuts correctly with the turbo on. Do use a torque wrench unless you want to be replacing another gasket + studs later down the track.

Their torque values are up surprisingly loose.

flexing the standard pipes too much will cause a bit of a kink if you're not careful... so be careful. oil starvation is bad mmmk.

[Trust33]

just take the pipes off and replace the oil and water at the same time..

When the turbo came off mine,in a similar situation to you,i found that the banjo bolt for the water line was calcified over closing off the flow of water of into the turbo significantly.So you might be able to avoid a future problem there.

More so on a stock turbo than an aftermarket 1 with new connecting parts.

I've found from experance that by trying to short cut doing something on an engine instead of doing it properly tends to make the job twice as long and often in the end you will have to do it anyway just waste time trying to short cut it ,but there are always exceptions to the rule good luck

You learn as you get older "do it once do it properly "

[Abo Bob]

Hmm, damn.

I didn't want to remove the lines because those bloody copper washers are so hard to find and cos draining the fluids is a pain and adds to the cost.

Oh well.

[legend01]

I have found it easier when removing a manifold to just undo the manifold leaving the turbo bolted on unbolt the oil and water lines and lift the manifold and turbo out together with my hks manifold I usually unbolt the engine mount under the manifold jack the engine up a little as well ,makes it a little heaver when removing but this has always worked well for me

i like to take everything off and work fast but not rushed. Its a hell of a lot quicker taking the manifold off while the turbo is off.

Stop procrastinating, you could have had it done already!

[dead32]

if you think you blew the manifold gasket, i would remoove the turbo and replace the turbo to manifold gasket aswell just to be safe, as those nuts/bolts generaly rattle loose and then you have a blown manifold to turbo gasket 1 week after replacing your manifold to motor gasket.. just my 2cents
