2008 V50 2.0d - Blue Smoke :(

Bent con rods is a ridiculous thing for a 'professional' to suggest; and so is Valve Stem Oil Seals (we can leave that one back in the 1990's where it belongs). Valve stem seal technology is that good these days that only something extreme (like extreme heat) would affect the 'sealing' ability.

The only way you can bend con rods is to suffer a snapped cambelt and the piston has made contact with the valves (even then the valves are the weakest point) or a cylinder has become full of fluid which can't be compressed.....which can bend the con rod under extreme force.

The con rods can be replaced but it's an expensive job.

In my case I've decided to get rid of the car by part exchanging it. I can't warrant spending any more money on it.

A bent con rod is usually caused when water is sucked into the engine , have you been through any floods recently? It is easy to check by measuring and comparing down through the injector holes .

Cheap supermarket fuel always made my 2005 Diesel Santa Fe smoke like a trooper. (Not an Isuzu..). When I put branded fuel in it cleared within 100 miles and never smoked.

Just a thought worth sharing.

My 06 2.0D had major trouble starting one day with lots of blue smoke kicking out. Well actually it was twice in one week, the second time it was pretty bad and took me about 5 mins to get the thing started.

I bought some EGR cleaner from Halfrauds (Wynn's I think), and sprayed the can where it told me to with the engine running. I then used Shell V-Power for a few tanks and have not had any problems since. It might be worth a punt at only about £10 a can before deciding to part exchange?

Thanks all for the replies. I have looked inside the EGR and although there was clearly wet-looking "soot" around the opening (where the silver pipe goes) and generally inside it didn't look tooo bad -- certainly not blocked.

I top up with Texaco Supreme 1 in every 4 top ups. The rest of the time it's just regular Texaco stuff.

Srcholmes -- interesting your problem was solved with a clean of the EGR. Where does it get sprayed into?

I'll give it a go with the better quality fuel and using EGR cleaner, but not holding out hope. I did unplug the EGR valve but it made no difference.

Mines on 210K and for the last 130K has been run pretty much on supermarket fuel, it doesn't smoke.

Might just have been the Sante Fe engine, I don’t know, but that is what I experienced on that car.

So far my 107k C30 2.0D Volvo seems happy to run on anyone’s Diesel.
