Castrol do one, but not cheap:

Not arguing with the idea of checking the bolt torque, but a long straight wall with a high pressure difference needs care and is a more likely point to fail. Ok, this time it lasted quite a few years (under lightish use) but making it a bit wider, maybe the same as the outside joining surface...
Took a while to get the new bits under the current circumstances, but all assembled and I have a compressor again!
The picture is of the underside of the cylinder head, and you can see the wall that separates the 2 chambers; not very wide so really a weak point waiting to fail.

Went to try the temp option which meant cleaning off the old gaskets.
The reeds are held between 2 plates, and the gasket between them is metal. However between the top plate and the head is a fibre gasket (same shape). When I started to remove this, the part that separates the two chambers...
Gaskets look OK, but that probably means nothing! I guess if the gasket that separates the inlet/outlet valves is leaking it could behave as it is, even if the valve reed is ok. May try the temp option, even if it lasts only a few seconds it might be a good diagnostic!
@Rig Pig : motor is...
Thanks for the picture, very similar to my compressor and pump/motor/pipework is identical.
The Cylinder that melted the air filter housing the one nearest in the photo, and the one blowing out of the filter/inlet is the furthest.
No sign of leaks, and in any case don't think this would cause...
Yes, heads off both cylinders and separated all the pieces. Both reeds, both sides, no visible signs of damage. Just 2 per side. Did a clean up and reassemble ,no improvement.
That's why I am slightly confused at to what can cause the symptoms if not the reeds or gaskets.
Hi All,
Looking for some help on diagnosing a problem with my compressor not building pressure.
It's a 2 cylinder V with 50L reservoir. Prodif V204705G.
Ran fine until recently, but began to struggle to get up to full pressure and cut-out, now only just makes the gauge move. These are reed...
