Drivers Side Exhaust Manifold Extraction

[ukkid35]

I've not done this before with the gearbox and drive-shaft in place. I've already removed the passenger side for extra clearance, but what to I do now? I presume I have to remove the PS hoses (or just the low pressure side?) Any and all advice my appreciated.

Remove RH engine mount, and a king note of spacer positions and jack the engine up.

I think I had to shift the LH one a bit on mine to get enough space.

Manifold out the top.

I've removed both engine mount lower bolts and jacked until the starter hits the bodywork. I have an early car so less clearance above the starter, so do I have to remove the starter as well?

[ridds]

Mine has the limited clearance also.

Have you tried moving the engine towards the passenger side?

[ukkid35]

I gave it a bit of a push, realised that was futile, and thought about using a bottle jack somehow. Then I realised there was a lot of potential for doing damage and decided that 1am wasn't the right time to try that.

When i removed mine, i removed both engine mounts, then the passenger side manifold, had the engine on a jack, and was able to wiggle it out, although at times i had to lean on the engine to move it over slightly.

Thanks for the advice, it's out at last, only took me ten hours. I know, I'm the slowest DIY mechanic in the world.

For what it's worth this is what I did:

Remove water rails and passenger side manifold.
Remove low pressure PS hose
Remove undertray (but used cable ties to keep the ARB in place)
Remove high pressure oil feed
Loosen oil filter clamp
Remove drivers side engine mount bracket
Jack drivers side of engine as far as practical
Lever engine against chassis
Use left hand to try to extricate manifold
Yelp when it eventually comes out

I can't see any possibility of exhaust wrap surviving the reverse procedure...

Repaired manifold, with extra bracing as recommended by my welder.

What a pig of a job to get it out. Mine are Cracked as well as well as having a few oil leaks to seal back up and a gear box to re-build you have out me on the pull the whole lot out route for sure as it will take around the same time i would think.

Hats of to you sir that is a rotten job you did there.

My wrap survived whilst squeezing the manifolds back in. Although some moved slightly.

Put the lower bolts in loosely then get the manifold on then top bolts. I made the mistake when putting mine in not putting them in having put sealant on it put it in place then thought f##k it got to take it out again.

[ukkid35]

They've gone back in without the wrap.

I just couldn't bring myself to work with it again, it is so unpleasant, and makes working anywhere near the manifolds a nightmare thereafter. It also hides the cracks as they develop, not sure whether it encourages cracks as well.

Not looking forward to the increased engine bay temps though.

Learnt this technique ***after*** we spent hours putting the manifolds back (first time).

Absolutely - but luckily you get to use everything you learn on a very frequent basis.
