When you say noisy.. Can you be more specific?
Or best option can you upload a video of it running? ( create a YouTube account or use gmail if you have one. ) then upload from your phone to this account and use the YouTube box above ( insert the code, not the full url)
Does it sound like this?
Can you hear the knocking over the revs?
It could also be piston slap, just annoying and not really detrimental.. But would come from more the top of the engine rather than the bottom.
If it's the bottom, like the video then a full rebuild is required before it explodes.. And it will if this is your issue.
Maybe oil pump is not working well and starved the engine of oil pressure. If you have this knocking now then rebuild / walk away..
Has it had a head gasket replaced in the past? - if the oil pump was not replaced when this was done then this appears to be a common failure ( providing it was never replaced before ) and I suspect it will not have been. Either way with the oil pressure indicator on this would be worth replacing ( pressure switch ) just to confirm correct operation. If the oil pressure light is on then fairly certain that the oil pump is not efficient enough and may have starved the engine of oil. Or oil pickup blocked..
If this is the case then only an engine rebuild will fix + oil pump!
But before I scare you - can you check the video or upload one?
