New K-series Cylinder Head

Sheraton · 15th June 2018, 17:41

How'do Folks

I'm getting there r.e acquiring all the parts i need to get my Car back on the road proper

she still runs and drives better than most on the road

but she is not in use.

I've still a few bits to acquire - Gaskets, Bolts....etc... not too much now tho

I received a Brand New replacement Cylinder Head complete with Valves today

there are a couple of small marks on the block mating surface should i be concerned about these ?

not sure what these 2 marks are

but they are not pitted

I’ve bought a few of these landrover boxed heads. Can tell by the green wrapping. The groove marks if there is any depression on them I would not accept as it runs where the elastomer of the gasket sits. The dimples may just be hardness QA check and from what I can see are not detrimental to the gasket seal. I still have a spare head and can have look see, but I think the grooves (if deep) do not look good at the end of the day, are you able to return to supplier?

I would not be concerned.
But I would not use the elastomer gasket either.

Assemble with the uprated gasket.

Gasket type should decided soley on the Liner heights ..

I only use the elastomer, I’m not a fan of the MLS version although I’ve never tried the N series kit yet

my initial instinct was the 3 areas with pitted dimples would not cause an issue due to location.

the dark lines i pointed out with thumb and forefinger are just visual

also the machining marks are just visual - the surface is Good aside from the 3 areas on the outside edge

the car has an Elastomer Gasket fitted - so i'll be looking to use Elastomer again - probably the Payen Blue Elastomer Gasket (forget the part number).

I'm replacing the Cylinder Head due to Suspected Valve damage - after the tensioner failed allowing the timing belt to slip and jump a tooth or few out of alignment

while trying to determine the damage i thought i had realigned the timing marks correctly ....

i hadn't and again while on a test drive i had a major timing issue....CONTACT

..... not a nice sound.

I got the timing/tension spot on at the side of the road and drove home 70 odd miles (i think) with no issues - currently the car still runs and drives and surprisingly well considering

(although not in use

)

the "Special K" impresses me more and more with time

she deserves a new Cylinder Head even if she doesn't need it

....and the deal i got on this made it potentially cheaper than valve replacement

hmmmm.....getting all the parts i have fitted will be another story

Paul, we have had a copy of the BW750 made - with all the strengthening of the later designs too. The best part? It's about 1/3 of the cost, and fast approaching 1,000 sold so far in just under a year with no issues reported.
Safe to say, they keep us busy!

Just the gasket:

As part of a kit, suitable for the 75/ZT 1.8/1.8T (with standard inlet) :

Definitely worth a look. I'm sure plenty of others on here have used them

How'do Mat

I was just looking at your kit

I was going to contact you to confirm what type Gasket as one image of the Gasket shows the older type without the additions to the Elastomer - and the other image shows the Newer type.

if it is the Newer design i will definitely consider it

this may even be the type Gasket I have fitted currently as it was part of a kit bought from yourself after HGF

I need a full kit, bolts etc.. and a few other wee gaskets, dipstick tube etc.. it'll be a week or so before i can make an order - this kit looks like a potential winner tho

do the Higher Tensile Bolts require the upgraded Oil Rail to be fitted ?

Paul.
