Bluesmoke

[Tottyman]

Very new to the forum , I have a 2006 lexus 220d . 75k miles . Had a major service at 67k . Prior to that a little lexus history . Recently I have noticed bLue smoke intermittent ( happens ad hoc ) when engine is hot .,this doesn't happen on cold start . Obviously burning oil , could this be my valve seats?blocked diewsel jets ? Any advice appreciated thanks

Hello and welcome to the LOC.

Blue smoke is normally oil being burnt but a bit unusual on such a low mileage engine, has there ben any warranty work done on it regarding the head gasket issues they tend to suffer from?

Its probably unburnt diesel,maybe leaky injector,blocked injector??

Hi gents , many thanks for your replies , Steve. I have been reading the many issues facing this model ( the dreaded diesel ) , I have contacted my local lexus dealer and they say my car hasn't had any recall , ( not aware of gasket issue myself 5th injector ? ) was this a lexus recall ? , must admit my local lexus ( jemca sidcup are pretty much stuck up and a little unhelpful ) I did have a major major service done there (£ 700 ) and they picked up usual discs and pads , caliper etc , rattly heat shield and that was it ( incidentally had my brakes discs , calipers done in Hungary at a Toyota dealer ( 300 all in ) . They didn't do my heat shield as they wanted£120 for putting two bolts in ( Halfords did it when they put new tyres on . Zoran , blocked injector ? I use premium diesel would it still be worth putting an additive in on next fuel up ( millers etc) . Thanks

Apologies , jemca sidcup wanted £120 for putting two bolts in my heat shield

It will be out of the engine extended warranty period now which was 107,000 miles/7 years whichever comes 1st so recourse through them would be futile ( Star Trek,the Borg always wanted to say that :) )

Worn valve stem oil seals normally give off smoke on a cold startup after the car has been stood sometime.

It may be worth cleaning the EGR valve as these do get clogged up,there is a good DIY video on Youtube.

If you generally only do short trips another idea is to give the car a good long motorway run on a regular basis at higher than normal revs to ensure the DPF gets regenerated fully.

Steve, thanks for the update on the warranty , it doesn't smoke on start up at all ( even when it's cold ) was thinking dpf other day and took it for a good run in 4th gear pulling 2k revs . , I haven't had a dpf warning on my dash . Baffled by it all really , hoping it's just the dpf ( the blue smoke , regenerating itself ) as I say it's intermittent and seems to do it at any time then it goes . oil topped up monthly ( Castrol edge 5w 30 ) . No loss of coolant , power etc. ,

The first thing to try is probably get some BG244 into it and let that work its way through to clean out the fuel system/injectors to see if that helps,one thing to note though is that it probably will smoke a lot more while your running the BG through it as it cleans the system out

Also clean out EGR valve if you can ,as steve says theres a good vid on youtube showing how its done

[Tottyman]

Thanks to both of you , will have a look at fuel system cleaner , egr valve . Will update

My car smoked a bit when i first got it ,only now and again it would do it..it didnt do it when i test drove it or i might have been put off lol !!

I gave it a good service,changed and filter using Mobil ESP,i changed gearbox oil,diff oil, fuel filter,air filter,cleaned out EGR valve and MAF meter and put in a can of BG244 and it cured it but im unsure which of the above it was that stopped it as i did the lot in o one go.

I now only ever use shell vpower diesel and i also use archoil 6200 aditve so everything stays clean (or thats the theory anyway).

When i service the car i always remove the EGR valve to clean it and touch wood its always fairly clean now so something must be right
