Removing manifolds what else should I do?

[lachiek]

Hey all, any advice appreciated here.

I'm removing exhaust and intake manifolds to replace my turbo but will also do a carbon gunk cleanup.

Is there anything else I should do while I have the manifolds off? Any tips for removing this stuff?

Cheers, LAchie

Gasket remover & / or a good narrow paint scraper.
Make sure you got all the necessary parts before you start.
Allow another 1/2 of the time, because it always takes longer. Start on Saturday morning or weekday. That way there is back-up time in case you need something else you forgot.
Ensure you block passages into combustion chamber so you don't unintentionally cause more problems.
Use an air compressor to dry / blow crap out.
Wear safety glasses.
Use a soft-blow hammer to tap a stuck flange loose.
Keep a couple parts trays near by to keep your bits together.
You could port-match manifold to block using bearing blue or similar.
We got some serious degreaser called corium. It's awesome, but clean away all residue before you re-install.
Loctite 515 / 510 flange sealant, 222 thread lock & 243 stud lock helps a great deal in sealing & keeping parts together.
Take it slow, do it once.
Use the correct torque for all bolts.
I did mine on my ZD30 & some bits were fiddly as, others ok.
Double-check connections before you crank her over.
Have fun, keep pics & enjoy

Take a pic at each stage, so you can go backwards threw your folder and install everything how it came off..

Thanks guys, all good advice. What about other engine areas that I'm going to expose with the manifolds off? I'm thinking I don't want to do this again for a while....

If you have an intercooler, i'd flush that, or at least have a look at th einternals to see if there is any buildup.

Yes while you have your manifolds off check all your hoses and clamps. I had a coolent leak, the only place i could see wet was the back of the head by looking from underneath along the top of the gearbox.
I thought was head gasket but was a small hole in one of the heater tucked up above the starter and under the intake manifold. By the time i got to that i was ready to take the head bolts out

How do you go about servicing starters and alternators?

when you flush the cooling system be sure to back flush it first to help losen any crud up

check this out its not patrols but lots and lots of good info ericthecarguy.com

Reverse fluch with thermostat removed (before you install the new one)
Starters and alternators can be rebuilt by acquiring the relevant bearings, bushing and brushes from a bearing supplier and / or auto elec joint. Hunt around as bearing prices can be cheap to the utterly rediculous.
With a multimeter you can really only test continuity of individual componentry within each unit, easier to demonstrate to you than type, or maybe google it.
If they were working fine before, leave them alone.

You asked what else, wellllll, that's something else.
Clutch master is much easyer to remove and then kit out with manifold off.
Starter--- strip, clean, re-grease, reassemble.
Alternator--- strip clean re-grease or replace bearings check brushes etc.
Just food for thought.
All back yard work I recon.
And knowing your bus inside out is always going to pay off, somehow sooner or later.
