Been kinda told I need new crankshaft bearing 

It's a ceg engine 2009 vrs 

Does anyone know what size they are cos I've found 2 types 

It's basically ticking very loud from when I start it and get louder and faster with revs. 

Plus major misfire ect. 

Or could it be fuel pump 

Got 2x bad reads from injectors 2 and 3. 

Ok, ask the guy who said you need a new crankshaft bearing something like "How does a worn bearing cause a misfire?" Laugh at whatever nonsense he comes up with.

 

Bad injector(s) or fuel pump seem much more likely, but error codes will go a long way to diagnosing which. 

Exactly mate. I was pretty much convinced it's a fuel problem. 

Then he came over and said that.. 

It's very loud though the noise

I've just had a thought. 

Maybe the head gasket has gone between the cylinders to cause the misfiring and tapping sound 

Could be a worn crankshaft or crank sensor thats causing the misfire? I would get it scanned for fault codes and perhaps a compression test to see if one or two of the cylinders are down on compression. Check the inlet exhaust manifold gaskets as well. Could be a blown exhaust gasket you are hearing.

Thanks mate. Will have a look. Just working in the cold and rain for the last 2 weeks is getting very tiring and then I get fed up. 

I love the car so don't want to scrap it as well.

Know the feeling. Seems to be freezing and cold every time they break down. Had to do my sons clutch in -5C. Gave up a few times when spanners were freezing to my hands. Waiting for it to warm up a bit to do the bearing and drop links etc on my 12 plate Octavia. At least I got a space cleared in a large open shed but still damn cold. As said get it scanned. It might ping up something fairly simple or narrow it down a bit.

It's not a good time of year is it for this hassle 😂

Well I think the mechanic might be right. 

I've taken out the oil filter and found metal in the bottom of the filter case. 

So looks like a conrod bearing. 

Will take off the sump one day this week if I can get a dry day to roll around the floor on haha

Metal in oil is never a good sign. Hopefully its a simple fix. Still dont see why a bad bearing would cause misfire unless its completely gone but if theres metal in the filter then something has worn. Hope the weather gets better for you

Alasdair

Thanks mate. 

Only thing I can think is cos the piston isnt timing at the right time cos of the play in the conrod and hence the misfiring. 

I hope I can get away with replacing the shims aka bearings or it means a crankshaft skim and I cba doing that so will scrap it. 

The metal could be just something else. 

Will obviously find out when I remove the sump 

The 'slop' in the conrod bearing would need to be truly enormous to significantly affect the timing of that cylinder - at which point either the rod would let go, or the piston would contact the valves. 

Oh right. Yeah thanks for that. 

It's burning my head out what's causing the misfire. I hope it's something simple. 

Obviously now me seeing very small metal particles in the oil filter has got me thinking conrod bearings but originally I thought 

Hpfp or injectors 

 

Four things on that readout stand out straight away - all intermittent.

- System voltage too low.

- Fuel pressure regulator.

- Fuel pressure sensor.

- Fuel injector number 2.

These all need to be checked.

Thank you bud

I'm going to give it a fresh oil change and flush for starters then can have a start on them problems. 

It's because of the ticking noise I'm worried. Also which I think is fuel pressure is once I've ran the engine without driving obviously it won't start again unless I leave it to cool down. 

Sometimes it will start but takes loads of cranking so it shouldn't be like that. 

I appreciate your help as well thanks 

Just to update people and thanks for your input 

The bottom bearings aka shim had gone on cylinder 3. I've managed to replace and repair it with engine in but don't know how long it will last

Thanks

Least you have found out where the metal filings came from. Hopefully an engine flush plus oil change and filter  will catch any that are still there.

Yeah thanks mate. 

Loads of metal. I did a flush and a light sand on the crank. Yeah I know it's not the proper way but I'm skint and don't have another car plus live on my own. 

Now I've replaced the turbo cos that was chat caused the oil to drop. 

Now it's warm cos I'm just in it now it's got thick white smoke. 

I take it that's from oil in the intercooler and exhaust. Plus my dpf is on and literally as I'm typing the coil light is on now. But was smoking anyway before they came on

Hopefully the smoke will gradually go. Had a volvo 940 with leaking turbo and it took a while for smoking to clear after I changed it. The DPF may have got too much oil into it. Hopefully it will regen and clear itself once cars back on road. I just ordered some wynns extreme diesel cleaner for mine as I had to move a pipe to change oil and it was pretty carboned up inside. Might be an idea to chuck an additive in the tank to see if it helps.

Thank you. 

Hopefully. I've not had chance to drive it cos of the problems so it should clear. 

I've managed to get my laptop working so will plug vcds in and look at fault codes. 

Cheers mate
