"K" seires head gaskets

<< < (2/3) > >>

maggers:
FAI do a head set with the multilayer gasket, available from  the likes of Euro Car spares. I've fitted a few & not had any further problems. It comes with a steel shim which fits between gasket & head face coated with a sealer which bonds to the head with the heat of the engine. The main problem with series engines is that when they overheat the gasket digs into the head face. When they are made the face is heat treated to harden it, this is only a few microns thick and Rovers' recommendation was that they should NOT be skimmed. I have seen heads skimmed, fitted & taken straight off to reveal the gasket dug in again - a total waste of time & a major reason for re-failure of the gasket. The trouble is many so-called "experts" will have you believe otherwise & sell you a skim. Using the shim is the only way past this as it takes the pressure of the gasket rather than direct on the head face which can now be skimmed.

carbore:
There are quite a few things you can do to a K series engine to overcome HGF tendencies, in fact some of them were done by Landrover as a recall. The main thing is the thermostat position change. My Elise also has an water-to-oil cooler that stabalises temperatues between oil/water and hence head/bottom end. The uber HG is just the icing on the cake as the cuase is the intrinsic problem with the cooling.

I have posted a few long threads about (around a year ago, or later) which you can pull out with a search.

But to be honest I would not have a K in a freelaner unless I had a very good reason (e.g. got it for silly money etc) or really wanted too!

But it sounds like the liners have moved, which is a far more difficult and expensive issue.

If they're still proud of the head then they haven't moved. As thats where they're supposed to be.

Sorry mate, it comes from not reading your previous post properly  :oops:

john boy:
Cheers guys just one question now done the gasket come to start it and got no compression :shock: timing all bang on do the elements need to be compressed and cleaned out of the old oil?

carbore:
Did you replace the head bolts? These are streach bolts and have to be replaced with the gasket?
