Engine Dead? Scrap or fix?

I think you could quickly rule out a blowing exhaust manifold by using a 'listening pipe' to narrow-down where the noise is coming from, a 1 metre length of garden hose should do the job... just move one end around around the engine bay while holding the other end to your ear. I'd start at the exhaust manifold.
 
hmmm... better get chopping the hosepipe! :) still not convinced it could be that loud from a cracked manifold though.. a missing manifold mabie.. lol
 
I agree it may be clutching at straws, but good luck!

Another indicator that it's a seriously blown manifold is if the noise gets significantly worse under throttle. Which might also indicate a blowing injector, which is also worth checking for (remove top cover, oily marks around base of injector = leaking injector). These are both fairly common problems!

And, if it isn't the manifold or an injector, you might still be able to pinpoint where the noise is coming from with the hosepipe.

the injectors have been check already.. and sent off to be tested (well the one we thought the seal had gone on (this has happened to me before) the noise does get alot worse under revs!

So it gets worse as the revs rise, but not whether it's under acceleration or deceleration?

i haven't really driven it through fear of it going bang! but when i rev it the noise gets a lot louder!

big end fail does that, does it struggle to rev very high ? if so it's pointing more and more at big end fail
but an engine normally loses oil pressure to get big end fail

again i havent dared rev it that high to find out... is there anywhere local to northampton that has an accord specialist that could possibly come and have a look?

if it was big end issues and i did happen to rev it to find out is it likely to do more damage?
 
and tbh do what Jon said, it really does work, and it really is useful to pin-point a bit more where the noise is coming from
 
Hard to say really, having a careful listen with the hosepipe might indicate an easy problem to fix, so I'd have a go at that first.

I hope it isn't a big end, but that could be repairable in situ if you're lucky (unlike a knackered timing chain/tensioner).
 
cool, thanks guys for all your help.. its too late now for me to start up the tank on my drive and get the hosepipe out! i'm gonna try and get back from work early tomorrow and play hunt the noise! :)

I will also get a vid of the noise on idle and revs
 
Looking forward to your next update...

well the update is here!!! i have a video of my findings and all im saying is that the noise has now gone! in fact its not making any noises any more! :(
I started..... i revved... it died :(

needless to say... its not the exhaust manifold. :unsure:

Vid can be found HERE
 
Im not being funny but with the engine sounding like that starting and revving it would be the last thing on my mind to do.
What chance you had of repairing this has probably now killed the engine.Hot fuzz had a simuler problem with the RAC.The guy kept trying to start the car and ended up causing more damage and totally wrecked the engine.
 
if the chain was slipped then all the valves would be bent and that didn't sound like all valves.

it does sound kind of big end but I don't think it is because there is also a nasty "breathing" noise

my hypothesis is that one of the valve stems had broken and the valve was in the cylinder, which is why you have that horrible breathing and metalic noise. If that was the problem then engine was/is already completely beyond economic repair without DIY skills to take an engine out and rebuild it (did that myself on a 1952 Daimler when I was 20)
 
I'm pretty sure that if you took it to a garage they would have started it up and did the same as you did in the video.

Yes indeed.. today is a sad day :(

To be fair i dont think there was much chance if any.. i agree its not something i was happy doing but i had revved it a few times before and all was fine, it just happened to be this time that the engine wanted to give up. i had convinced myself it couldn't get any worse so if it gives someone a better idea of what it may be then it was worth it.. bad move i now know :(

Thats not something i would have even entertained! im not that competent with cars, minor service etc im fine with but not happy taking engines apart! :unsure:

My mechanic can't believe it locked up but is now on the look out for a new engine, all i need to do is find someone to fit it cheap enough (he's far too busy at the min) :rolleyes:

Im sure they would but the fact is the engine has been started up several times.A good garage would hear this noise and stop straight away and start to investigate.
I had an old 1.6 diesel astra years ago with a noise like this and stopped straight away.Called the RAC he started the car and turned it off within seconds.
It was one of the followers broke or like tappets in a petrol car and was broken and wedged down in the valves lucky for me it was saved and repaired.

As you said anyway it did sound like a new engine anyway but it would be nice to find out the exact cause of the problem.

"Just had the news from my mechanic the the reason my accord sounds like a tractor is that the piston sounds like its hitting the valve!!
He thinks its a new engine job! he thinks the timing chain has slipped and caused the damage!

i did see there was a repair regarding the timing chain that HUK were doing free of charge.. whats the chances of mine being honoured not the damage is done?

im gonna have to sell as is or break for parts i reckon?? "

hence the ideas in the thread

anyone know what the engine code is??

Damo did you get the code read if so it might give us more of a clue of what the problem was.I would still get this read for piece of mind if there is one.

Fair comment but i would have nether restarted the engine with a sound like that.
It would have been a tow truck straight to a trusted garage or dealers.

But worth it mate im up there all the time for service and mods as iv had bad experiences from other dealers.Its a 260 mile round trip for me but would have been a lot less for damo
 
Northampton to Stoke 95 miles in Google Earth.

Damo it's not a bad idea tbh.

I've seen a place that rents low loaders for £100 for the day, see how much HH will want to collect the car from you
