Ekona Posted April 9, 2015 Share Posted April 9, 2015 Unlikely. What oil? Any other symptoms? Are you 100% sure you didn't overfill it? Quote Link to comment Share on other sites More sharing options...
-Bradders- Posted April 9, 2015 Author Share Posted April 9, 2015 i put 4.7l in with a filter change. erm.. its shell oil lol might just run it through and wack something better in. no other synptoms running as per. just smoking. Quote Link to comment Share on other sites More sharing options...
techinstaller Posted April 9, 2015 Share Posted April 9, 2015 Thats thicker oil so would in theory burn less and smoke less ,how many litre's you fill it with ? Quote Link to comment Share on other sites More sharing options...
-Bradders- Posted April 9, 2015 Author Share Posted April 9, 2015 as said 4.7l with a filter change too Quote Link to comment Share on other sites More sharing options...
techinstaller Posted April 9, 2015 Share Posted April 9, 2015 What colour smoke ? i assume from the exhaust you mean rather than under bonnet? Quote Link to comment Share on other sites More sharing options...
-Bradders- Posted April 9, 2015 Author Share Posted April 9, 2015 yeah exhaust lol and light bluey white it stinks of oil. Quote Link to comment Share on other sites More sharing options...
mouthwash Posted April 9, 2015 Share Posted April 9, 2015 I don't know much but I know blue smoke is bad, do you have cats/decats? Quote Link to comment Share on other sites More sharing options...
techinstaller Posted April 9, 2015 Share Posted April 9, 2015 that does sound like an oil type smoke but theres no reason at all for just an oil and filter change to cause that ,did you run with an engine flush in by any chance before the oil change?( just to eliminate that as a possibility for causing any damage) Quote Link to comment Share on other sites More sharing options...
-Bradders- Posted April 9, 2015 Author Share Posted April 9, 2015 nah no flush and recently added decats Quote Link to comment Share on other sites More sharing options...
Keyser Posted April 9, 2015 Share Posted April 9, 2015 Suppose it depends what was in it before (if anything ) Thicker oil should (as said above) smoke less - I've seen 350's run on 10w/50 with no ill effects - especially if you run hot (like I did with High comp pistons and FI) I did always warm her up though I don't like coincidences though, unlikely that changing the oil would cause the engine to die, - You did nothing else when you changed the oil - just filter off, new one on and remove/replace the sump plug? Nothing else that you may have put back together wrong by mistake??? The only other thought that jumps into my head is if the valve seals were worn and you used a thicker oil, you may actually increase compression (marginally) that may let more oil in via the seals hence the smoke - but I really am clutching at straws at this point Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted April 9, 2015 Share Posted April 9, 2015 (edited) As above... And just in case: (looking at other threads of this nature and clutching at straws as I've no idea) no harm in trying some injector cleaner first. possible head gasket (have coolant levels gone down?? but more likely to just be white smoke) check the PCV valves as well (someone reported it being snapped in half!) check the oil pressure sender is tightened up.

ChrisB Posted April 9, 2015 Share Posted April 9, 2015 And another wild one - you did your plugs recently too yes? - was there any oil in the plug tubes that could have found its way into the cylinders? Might be just a temporary little pool burning off inside the decat exhaust as it gets hot - maybe 1 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted April 9, 2015 Share Posted April 9, 2015 Ditch the shell fluid and refill with a recommended tried and tested brand, suitable for the VQ35DE. What oil brand were you running prior to this issue ? Remember and empty out the filter as well which should be OEM. Also check that the ECV is working as it should, you will find it screwed into the cam cover. 2 Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 9, 2015 Share Posted April 9, 2015 I would start by swapping the oil filter you fitted with another, just in case its causing a restriction, and as said check the functionality of the PCV system as this can also cause smoke if its malfunctioning, What grade of oil was in there before the change? unless you where using 10w50 or 60 I cant see the oil causing the smoke.

-Bradders- Posted April 9, 2015 Author Share Posted April 9, 2015 had valvoline 5w30 in before. also as above i did do the plugs at the same time ansd one does have an oil leak but it didnt smoke like this last time i done them and the leak was there then too!!

Darren-B Posted April 10, 2015 Share Posted April 10, 2015 You have just answered your own problem, When you removed your old oily plugs you have released a pool of oil I tot he combustion chamber which hopefully wasn't enough to compress & bend your rods on first atartup (I doubt it as it probably would have locked on the starter) Now all the oil that has drained down is burning off on your headers & cats! This should probably clear after a while but don't go Hooning it until it clears 4 Quote Link to comment Share on other sites More sharing options...
-Bradders- Posted April 10, 2015 Author Share Posted April 10, 2015 ive done about 8-10 miles and its still there and i left it idleling for about 30 mins before that too. theres no loss of power car performs much better since the service lol Quote Link to comment Share on other sites More sharing options...

Ekona Posted April 10, 2015 Share Posted April 10, 2015 PCV, Positive Crankcase Ventilation valve. From wiki, 'cos I'm lazy: The PCV (positive crankcase ventilation) valve is a one-way valve that recycles crankcase gases back into the engine to burn. A plugged PCV valve can result in a rough idle and poor mileage. Worse, it can cause costly oil leaks. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted April 10, 2015 Share Posted April 10, 2015 (edited) pvc? evc? were are these things lol They are the same thing, just different terminology and I told you where it is fitted in my last post. ECV = Emission Control Valve. Edited April 10, 2015 by ZMANALEX 1 Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted April 10, 2015 Share Posted April 10, 2015 is it something thats plugged in? maybe i unplugged it and didnt put it back lol? ill have a look today!! It screws into the R/H cam cover beside #1 coil pack,and a breather hose leads from there. You can't miss it. 1 Quote Link to comment Share on other sites More sharing options...
