Thread: advice needed......lurch has a headache.....

i might have to wait till the weekend when the missus goes to work.........

then i can use the oven safely........

she sleeps right?

So you go to the local hardware store and buy lime powder get the wife's best baking tray fill he manifold and cover it. Bake it for an hour then let it cool in the oven before removing.

Clean the manifold and done. Rather then it's ready for skimming.


Is there any decisive advantage to doing this

when your working some metals (in particualar removing webbings or welding)
heat soaking and slow cooling can allow the metal to naturalise its position prior to any measuring or machining.

IF....

the metal is stressed and you machine it and then you heat it it can want to assume its "more comfortable" position which can then put stress on other fittings (say manifold bolts).


hope that makes sense.

Thanks Blknight

Is it really as simple as I said you just ask for lime at the local hardware store

Fill the manifold and sourround/cover it in lime and bake for an hour and allow to completely cool.

Is there any risk of the process damaging the manifold.

you dont need the lime if your doing it in an oven.

the lime acts primarily as an insulator. It also can leech impurities away from the metal but its been a loooong time since I touched metalurgical chemistry.

its really that simple..

do all the work you want to do short of facing the manifold

heat soak the manifold

get the machine faced flat.

Blknight,

Thanks that makes it easier to explain to the wife. Just baking the manifold.

Mate seems nothing to loose so will give it a go once I've elongated the holes and taped for the EGT probe.

what egt and how much are they.........


ive been meaning to do this for about 3 years now........
but i keep putting it off till next weekend........
