Maybe blown piston?

[holymother]

For awhile when starting, a loud clacking
Noise would happen. But when I revved the engine
The sound would go away. I was running
It the other day and the sound came on
And is there all the time now

Is this poetry corner?



You need to compression test
that'll probably be best
maybe a bearing is shot
or indeed has holed a pot.
