Threedogs motor thread

I wish I had the dough to come up and help you, as I have the time to do so, next week, when everyone is back to look after our animals.

What does "holding residual pressure for a while after shut down" mean? Coolant not being sucked back into radiator as motor cools down?
Hate to say it but I also think it's sounding like either a cracked head or a cylinder head gasket blowing between cylinders. Given that it runs ok for 20kms or so before playing up I'd guess that the cracked cylinder head is more likely.

Heya Cuppa. Yeah the coolant won't return from the overflow and the pressure shifts a bit (depending on how bad the problem is) of the coolant out and away via the overflow reservoir.
Mine is doing it at the moment. I ease the pressure of a morning by bleeding the top of the far column (triple flow radiator) and gently cracking the cap.
I found I don't need to replace any coolant as it settled in about 1/2 way in the top tank. Just ease pressure and motor sensibly.
New head gasket next week will return all to normal.

3D i hope this is all your problem is bloke, you got enough going on without major engine issues.

How much dosh would it take ?

I know it’s often said that a blown a head gasket means a new motor, maybe it’s correct, but it sounds pretty extreme to me.
I don’t undertand why the labour to remove & replace a cylinder head would cost more than replacing a complete motor (along with all it’s ancillaries)?
Is this specifically a 3 litre Patrol thing?

Easy trick for you to do which you do when you bleed the cooling system. Stick the coke bottle in with enough fluid in it so you can see it. If you get lots of bubbles continuously, even little ones, the something is gone whether its the head or gasket.

A good mate of mine runs a shop. Last quote i got off him to do a head on a zd30 patrol was 2200. So not motor replacement money. This was a retail quoate as well it wasnt for me.

Don't want to piss you off TD, but you have given advice to about everyone on this forum about every single issue to do with Patrols. What is the problem solving this one?
I really thought you know your shit but I seem to think otherwise.

If it is just help you're after with lifting/removing/moving/installing then I am more than confident people will jump in and help. This is what this forum is all about.

Just seems strange someone in your knowhow is struggling figuring this one out.

Wish I could help mate but I'm just a Patrol driver not an expert.

snip...
ATM I think Ive clogged the system with head repair goo.

Hmmm... wouldn't be the first time that has happended.

I'd be more suspicious of that and what Cuppa and others have said rather than fans etc

When my family friends CRD went ass over tits, I was there when the mechanic done exactly this. They knew the motor was gone, but just wanted to prove a point. I remember you could actually smell exhaust fumes coming out of the coolant at the radiator as bubbles.

Im not to mobile atm need to pic the time when Im feeling ok,
thanks Winnie makes me feel better. First job will be to remove and clean
the radiator and replace the thermostat
Im a big fan of doing one thing at a time so Ill know what exactly is the problem

How are you going to clean the radiator? Id be taking it to a professional and get the tanks removed and the core properly cleaned. Otherwise you will be just wasting your time i reckon.
Looks to me he car just needs a good cooling overhaul.
We hope....

Yeah i have a 2ltr coke bottle cut in half with electrical tape wrapped around the neck so it sits tight in the rad. Works a treat this one.
