Which head gasket to use

#1 Post by G.Watts » Mon Jan 20, 2020 2:11 pm

Hi everyone my 2006 rover 45 k series has had HGF after removing the head I checked the liner heights and found they were only 0.05mm above the block there are quite a few opinions on which gasket to use. I would like to use the mls gasket but I’m not sure my liners are high enough your thoughts on this would be greatly appreciated

Others may disagree, but I'd be happy with one similar to this BGA one:
Image
While this is often described as a MLS gasket, I tend to think this is a misnomer, as there is only a single steel layer, and the black layers are polymer mouldings. Being sheets, much less prone to bursting than the original beads.
I think the restrictions on liner height variation must be due to the reduced flexibility of the 'true' MLS gaskets, with multiple steel laminations, from Land-Rover, however the one shown above retains the same single flat steel layer with crushable fire rings used in the initial k-series design, so should match it for flexibility.

I used the BGA on a 214 I bought with HG issues. It hasn't had much use since, but the job looks OK so far.

Shim liners and use the latest Victor Reinz 61-34835-20 with built in head saver or the SIAC gasket from Xpart/discount MG Rover spares.

OE original, get a complete housing as they’re prone to leaking when disturbed.

What the more modern k-series used to get rid of the terrible bleeding coolant system of early k-series.

Pressure release thermostat, almost self bleeding.

A great upgrade to those who frequently change coolant. Relatively cheap upgrade, main cost is the new pipes but the thermostat it’s self does fail regularly (or at least mine did).

Thanks for your comments I’ve not heard of the PRT so I may go down that route,is there a blanking plug and seal available?

If you want to avoid HG failure again fit the PRT thermostat unfortunately it is a bit of a fiddly job especially if you have the R65 box as starter is in the way and the difference in the pipe diameter from the PRT to the lower radiator pipe

My car is a 1.4 so I think it has the R65 box, rimmers list a complete PRT kit so I was hoping it was a simple bolt on job
