Engine blew?

Hammering sound that rises with RPM, big end bearing or crank bearing?

I guess you need a video for this one?

yes quite likely. Have you checked to make sure the engine hasn't inhaled something it shouldn't? Take the plugs out and crank it over. Could also be a cam/valve problem too I guess. It depends where the noise is coming from.

Sound is heavy, not very light, I would say it comes from engine block, but can't really say for sure, valves do need adjustment as they rattle a bit, but that should not cause this heavier noise, I think?

You need to click play, it loads, then click play again when it appears, you can hear sound at end of the movie.

Ahem, yes it got stuck and yes, I did give him a little bump with V8

i'd say crank or big end bearing, because the engine is still very properly running on 4 cyl. if there's a valve or head problem it won't.

can you feel if the flywheel is still bolted tight trough the hole in the bellhousing?

I can't find it being loose, at least couldnt move it even with tools.

I'm not happy camper

Sound has been there long time already, but it is now louder. Car has not been used for quite a while.

It runs without sound today, self repairing engine?

is the pulsair system loose?

how does the starter motor (and flywheel) look like if you remove it? does the starter motor engage and disengage smoothly (the axial motion to put the gear in the flywheel)

We did not get pulsair system here

Everything seem to be operating just normally now, starter works like new, gear comes off from flywheel as it should.

oops, finland sorry

with a loose pulsair hose it makes very similar sound

i don't have any other ideas wich would have solved themselves. can't be a bearing, that sound will only get worse

it's still worth lifting the valve cover to see if there are any unwanted items present, and a swap of engine oil + filter.

could also have been the viscofan hitting the radiator shield due to worn engine mounts
