Finally bit the bullet after fogging out the road behind me with white vapour and started dismantling my V8 to find the problem.
The following pictures are the result.
Not the best pic of the plenum but the blue bits are the gas injectors for the LPG. The rails had to be removed from plenum which meant removing the tubes from the injectors (after labeling everything). The allen head bolts holding on the plenum were sprayed with penetrant the night before.
The throttle cables had to be unclipped as did all the vacuum hoses.
Notice i have labeled and numbered everything.
Six bolts hold in the ram housing which came out easily.
To remove the intake manifold i had to unplug all the injectors, to remove the injector loom i had to take off the fuel rail :doh:
There was loads of crap on the inlet manifold. I removed as much as possible before removing it but as you can see from the pics there was still a load i could not get.
The crap has a blue tinge so i think most of it is crystallised coolant.
A couple of the coolant hoses had holes in them in places i could not see until i had removed them hence coolant EVERYWHERE!!
Underneath the valley gasket was not too bad at all, just a little brown.
This was the side of the gasket with the biggest leak. The brown/green/yellow stuff was a sort of soggy crystal substance which i think is half dried coolant and hylomar with maybe a bit of silicone thrown in for luck.
:doh:
:doh:
:doh:
:doh:
Who would have though only last year the only thing i would do to a car was put fluid in it!!!
lets hope it all goes back together!
Anyway i will be spending most of tomorrow cleaning up the mating surfaces.
Im thinking that i will take the injectors out too and give them a service.
Also im going to degrease everything then jet wash it before sprucing it up with a lick of high temp paint.
Anyhoo ill post more as i do it.
Cheers,
Stu.
