Snapped Exhaust studs part II

[Jules-C]

Yeah look pretty good to me too.  The ring marks just look nothing more than marks were it's been sitting for a while and nothing to worry about.  I think you risk doing more harm than good if you try doing anything more to them

[anutz]

yes i think less is more in some cases, especially with this stuff......i need to make sure i am careful when i remove all the old gaskets on the mating surfaces as well.....

[red98]

Look good to me.... .....did you see the engine running before you bought it ?

[anutz]

no...

but i have assurances in email before i bought it ran etc....so any major issues i should be ok....i hope!

what can go wrong eh!!!!!

[anutz]

In the intersts of keeping the landing page from killing internet connections with hundreds of image downloads i will just post updates inline...

So cylinder head been drilled and all exhaust stud holes look good, got a stainless steel set on the way i got for 7£ so will fit them when they arrive...



And....



Ignore the head in the background, one i got off ebay and when it arrived the camshaft caps were snapped so its for the bin....

Head and Cylinder gaskets on the way as well...

Anyone tell me what this component is - its the white thing i removed from the recess above, i think it must be oil pressure sensor or something....has a orange rubber O-ring, i cannot see it in the service manual - but am still looking

The left hand hole is where the water pump fits, i have removed that for cleaning....to the top right would be the sprocket....hope that gives you a location

Currently cleaning the engine as you can see

[mobile mouse]

It looks like the neutral gear sensor. the orange rubber is an oil seal.
When the gearbox is in neutral then there is a brass pin (this pin rotates when you change gear) under were you removed the white plastic unit which makes contact and is a short to ground i think and the green neutral light on the instrumentation lights.

thanks for that mobile mouse - indeed that is what it is......

[anutz]

anyone ever used shot blast on the engine to clean it up....been reading about soda blast as well which leaves a protectvie film on until you paint it...

or am i asking for a world of pain

[sinto]

Not that I've used shot blast anutz, but I've only seen it done on biggish bits of metal etc, not seen it done on engines.
But I've heard/read somewhere about dipping the engine in some sort of solvent, but check up first as I'm not 100% sure what solvent etc

[mobile mouse]

google vapour blast... and select images


I have never seen parts so clean, they can do whole engines.


There may be someone who does it near you..

[anutz]

will have a look into that, right now i need to take the head down the engine shop, looking at it there are one or 2 tiny marks on it, want to see what they think, one is near a water jacket channel ( assuming thats what its called ) but its not borken the perimieter of it

Pistons cleaned up and almost ready to re-assemble, any one recommend a good piston ring compressor they have used?

[His Dudeness]

What did you use to clean the carbon off the pistons?

[anutz]

this stuff....

http://www.amazon.co.uk/Gunk-6863-1L-Degreaser-Cleaner/dp/B006ZZ4AHS/ref=pd_cp_263_2

worked surprisingly well considering its not corrosive or that harsh, green friendly as well...

[His Dudeness]

Ok thanks. Is it just a standard degreaser?

[anutz]

i think so - not sure what other considerations they are about it - i chose it as it was "green" and was sick of using what i would deems as hasrsh cleaners that made your hands sting if you got a tear in a glove etc, this is a little potent but less trouble, also supposed to be eco friendly.....
