Oh no! gutted for ya
I was in a bit of a hurry when I did mine, just removed the breather hose to gain access, strangely the leak was a pinhole in the casting, panicked a bit when I saw steam coming fromNew box of tricks came through today.
Nice shiny new throttle body heater! mine has been leaking for around 4yrs!! LOL
The leak has been somewhat stemmed by me covering the old gasket in RTV, however it still leaks enough to drop the level in the expansion tank..
And its annoying!
To pull it off the throttle body has to come off 4x 8mm for the body to manifold, then 3x 5.5mm bolts for the heater itself, lastly disconnect the throttle position sensor and crankcase breather and its out!
The throttle body itself needed some cleaning, I just rubbed he mating surface with some cutting compound to remove any rough spots.
And as Haynes says etc
Job jobbed and after a good run its leak free..
the front of the bonnet, was a very fine jet of coolant hitting the rad.

Think outside, no box required.
Did you replace the rocker shafts?
No but they looked in good order, as did the pushrods. Noise is/was coming from the middle of the engine

Sounds like you need to check the oil pressure.
Already done that, it was around 36-38 psi at hot idle
Yes it's quite a substantial knock, not the usual tick tick tick

Bugger.
you did torque up the big ends didn't you?.
I did, yep.Bugger.
I'm almost convinced it's destroyed a lifter some how
Once had a knocking but not exhaust manifold but inlet manifold
In 2 other cases on different engines one a 2'6 RoverSDI and the other a 300tdi were head gasket to outside air. Both engines ran OK but knock, knock on reving
It quietens down with a few revs
Process of elimination and you'll sort it. Just take your time and all will come goodIt quietens down with a few revs
I like your optimistic view! Not much else left though
I was convinced I'd find the source with the dodgy looking lifter
