if not it is the first and last time a PCP has dieseled
Could I repeat it??!!
I wouldn’t want to try!
Others on here have reported dieseling too, so I don’t think it was the first or indeed last incident!
(and no, I’m not gonna try and trawl through a gazillion threads trying to find the posts)
I accept that it’s rare, otherwise with my reasonably carefree attitude, it would have happened more often. But I know what I heard/smelled and it was most certainly a dieseling incident.

It could only have been 3in1 oil (mineral). Some must have got into the breech area after I’d had a strip out and had oiled down the barrel. Up to that point I’d been pretty free and easy about using mineral oil, didn’t think it would happen. Though I was running around 3500psi of pressure at that point, trying to get Jerry slugs as fast as possible. Definately dieseling as opposed to an oring letting go as you could smell it too.
Pabs, what was the fuel and where was it located?
will test it out and if it worked maybe 1600fps is possible 🙂
I’ve had it happen to me Walter, when I had a full bore blod valve going. Made a hell of a bang, though unfortunately the combro didn’t read so I don’t know what the fps was…..
I don’t see a PCP dieseling either.

Maybe you could use the super soaker example so him and his mates can theorize while playing army and fireing peas and water around. Chase me chase me all lubed up with cv grease cos his mate told him its good for him.
Might sink in with him but dont loose sleep over trolls 😉
Some people won’t be told Ian. I’m sure his little mates will be along at some point to try and back him up.
Just can’t believe he doesn’t understand the basic principles of the thing! He even uses the blowpipe example, which is great cos when you blow down it, you can FEEL the initial resistance. So obviously the air between your mouth and the projectile is getting compressed a bit. Times this by a thousand for a pcp air rifle!!
DUH!!
Lol, i thought you did well there in not telling him to get fucked, quoting names and shit to people
😆 😆
Yep, he should do some more research, or stick to blowing pipes.

The temperature build up (if any) from compressed air expanding into a space as in a PCP is MUCH less than the temperature increase from compressing several CC’s as in a diesel engine/springer.
I’d also posit that in a PCP any temperature increase of that tiny bit of air behind the pellet is negated by the temperature decrease of the large amount of expanding gas from the tank.
I’ve never had a PCP diesel – not even after cleaning which is usually the only time my springer’s diesel.
