Hi,

I need to replace both cylinder heads on my 5.2 ZJ.
I don't look to make it better thant the original but they are dead (valve guide are dead).
I also need gaskets and all needed small parts.

Do you have a recommandation to purchase as I'm in Begium?

I also need a water radiator, it could be a group purchase but the radiator is less urgent.

Thanks and have a good day,
JC

PS : Members at JeepForum.com are sending me here as you and me are on the same side of the atlantic ocean :-)

Everything you need should be available from rock auto.com

Doubt you'll find new heads just get an engineering shop to recon the originals.

 ...crack test, skim a few thou off and replace valve guides...port and polish, if you are serious about it.

[Jean-Christophe]

It is cracked.
The use of LPG is deadly for those kind of cylinder heads...
A head gasket leak made my engine to overheat. Analysing the cylinder head relealed cracks and valve leaks.

I believe I realy have to change them.

[Bubba]

are they aluminium heads then ?

[Mike Pavelin]

Should be iron IIRC

[Bubba]

thats what i thought

[Jean-Christophe]

I don't think it as aluminium heads (but the are at the workshop now).
The valves where badly damaged by the LPG, as I understand. That's why they are not sealed anymore.

You lost me with "iron IIRC". What is it?

[wildwood]

IIRC means: If I Remember Correctly

Hopefully just new guides and valves /seats will be needed....
