Leaking pressure relief valve?

Could be any number of things, regulator set incorrectly/defective, unloader valve stuck/defective, reed valves cracked, snapped or wedged open with crap. full of water, no air space.

Its scrap most likely head gasket is also the valves can't get parts. Buy a proper compressor if you use it more than 1 time a year thats whats inside probably blowen in middle the shims are the valves lol https://i.ebayimg.com/images/g/HswAAOSw0cVc9HMx/s-l1600.jpg keep the tank . i got my one to work, but it only gets to 2.5 bar won't ever shut off just good enough to fill tyres after head gasket messing abouts i think its also worn the piston and boor as it was running for hours when it failed

It wouldn’t be the first time I have fixed one of those where a bit of crap has got stuck holding one of the flappy valves open. Take the head off and check to see.

Use some RTV or make one from some cardboard.

Probably broken reed valve- cut a new one from a feeler gauge. That’s what I did to mine years ago and it’s still going strong

Gasket paper is available . RTV will work for a while but does not last .

Bought mine not running about 15 years ago & was a supercheap model, twin cylinder. Would barely turn itself over but was a faulty capacitor. Didn't end there though as 'that' made it run flat out but getting nowhere. Pulled the head & reed valve on inlet side was missing, no doubt previous owner had been in there looking for why it'd barely spin or wouldn't spin by memory & just blew the overload button. Made a reed out of a feeler blade of similar thickness to the existing one. Been a good compressor for all those years.

Contact Wayne at Electrics in Motion in Hamilton, he took over the stock when we closed our repair centre, I made up gasket sets for the Supercheap compressors, they are most likely the same as there appeared to be 2 styles of heads on these machines , he may still have them available.

Just go buy another one, cheap as chips. Nothing is worth repairing unless it is a bigger one that is used heaps with large capacity.

Now let me see, shall I buy a $10.00 gasket set or a $300.00 compressor, tough decision.
The OP has a 2HP compressor, even the 1HP models are around the $200.00 mark, this replace it attitude is why our landfill sites are filling up, the compressor only needs replacing if the repair cost is uneconomic

My Supercheap compressor which I bought when they first arrived in NZ had a problem with the head gasket. Made my own with some gasket paper I had lying around and it has been running well ever since

Plenty of hollow ground to fill up here, also plenty of hollow politicians minds as well.

My honest suggestion would be to pull the head off. You literally have nothing to loose as the compressor aint compressing now.

Where’s the Kiwi ‘can do’ attitude?
