That pic looks like the valley gasket metal clamp. The bolt is nowhere near the coolant, so unlikely to be that.
The leak is most like one of the two coolant ports on each head. If I remember correctly the inlet manifold block the two rear...
Took me a while to get SDD to work, but seems to be working just fine.
The CD400 radio is exactly the same though.
(i can't confirm this was an exact replacement for the original)
Will SDD tell me what came fitted as stock?
I've tried...
Had a ,look this afternoon, one side the bolts to the ARB come off, the other side is rounding off. I am lucky to have a 2 post lift, so will drop the subframe, and then be able to get a good grip on the offending bolts and get the other arb out...
Update. Firstly stipped and cleaned the injectors, inlet manifold, inlet ports. Then cleaned out all the carbon build-up from injector-2 port in the head (other three were fairly clean but did them as well).
Cleaned out the vortex crank...
That's what I have been installed for 10yrs now no trouble as yet makes a big difference on long hauls all round , straight forward to fit I also fitted the larger sump with the cooling Finns 👍👍
What a magical day I had today 🙄
Thought it would be a fairly quick reassemble of the manifold, oh how wrong I was!
Refitted and torqued up 9 out of 10. Number 10 become righty loosey 😢😢
Stud almost fell out.
Panicking about what to do as I...
Hi only going on various threads I have red and several mention 12v supply and a max 5v back on the signal line, but thinking it through if a sensor went sc with a 12v supply then you would get 12 back into the sensor input which I doubt it would...
I guess you get what you pay for.
This is the part I ordered for £5.99.

It was the cheapest on Ebay but for a reason. The spring that keeps it in tension is so weak when I go to open the door the window...
Update:
Found the right cap and pressurised to about 14 psi. Leak quickly started dripping from around the rear of the engine. Stuck the endoscope down and saw this:
That looks like the culprit. Looks like coolant is leaking out of the bolt...
I'll have a look now.
I did get this picture of the rear valley gasket seal, it does look a bit wet there although is hard to tell with this tiny endoscope. It seems that signs are pointing to it being the source though.
If it is - is there a...
