Essex lanes

Well quite an epic afternoon! Went to collect the head gasket, bolts, and head set, then the head after a skim, and got home. Drove the Disco to mikes and it drove absolutely fine with no overheating. I had previously blocked off the matrix so we plumbed it back in and went for a drive. Had heaters and no overheating (thought the 4 bottles of kseal may have finally worked lol) then i lost heaters
So on with the head swap!









I got excited at this point, as the head bolts weren't tight at all, id even say they were loose. Undone them with a ratchet with ease!
Due to the water in No.1 we looked closely and saw this:






Thought it may have been a crack, so headed up to PEC where i had the head skimmed, and borrowed some chemicals. Came back and tried them:








Mike fisting my hole:







But this showed no sign of cracking. So got on fitting the new head:









So all back together, and run up lovely, steady temp and had heaters. Drove home and kept the ideal temperature, but lost heaters Dont know whether its because it needs topping up from being completely drained and we've not topped it up enough, or more likely theres another issue. So either the block is actually ****ed and we couldnt see it, or the matrix is ****ed.
Tomorrow ill check the levels and go for another drive and see whats what. But at the mo im keeping a steady driving temp so you never know, but as you can imagine im gutted
But i must say a massive thanks to Mike for helping, and Rob (PEC) for the loan of aforementioned chemicals, and the head skim!

Those crack detection sprays are awesome, we use them at work

hopefully its just an air lock and just needs bleeding some more.

Air lock now surely??

I would say air lock, bleed it with the OS wheel on a ramp, maybe try filling the matrix up first...

Yeah i tried bleeding it on the ramps previously, but im off outside to have a go in a bit!

Anyone know which way the feed is on the matrix? Is it the one out the head or the one that goes to the front?

Mike might remember from when we tried it. Should be able to take one of the pipes off and run the engine to find out.

ive tried googling it and doesnt seem to be the same way round

Weird. We pulled one of the pipes off and with the engine running got the water to pump out of it to show the flow direction. Just can't remember which one it was

ide check all the pipes for blockage

Is anybody going bures on the 30th

Well tonights update as follows!
Undid both matrix pipes. First one on top of the head, and it flowed out of the head. So naturally youd think it would come out of the other side of the matrix once reconnected, but no! Its flowing from the head AND the rad side to the matrix which might be why ive no heaters, as its not actually flowing through it, just pushing against each other. Its warm enough in the cabin to take the chill off but not actually warm at all. BUT..... When its at high revs you do get a bit of heat. Not hot, but some. So theres either an air lock still, or the water pump is insufficient. We put the hose through the matrix last time so it was clear then. When i can get to a hose ill try it again.
The engine doesnt overheat now though which is marvellous!

Does that mean you can keep up with my Bus now.
I rather liked having to slow down to let a Disco catch up.

Sounds like the water pump is a bit weak, have you got good flow through the top hose do you know? Least it's saying cool now though...
