Tanuki Posted July 16, 2012 Share Posted July 16, 2012 White smoke implies unburned fuel. Could there be something in the snorkel that is periodically blocking the air-flow ?? That would cause it to smoke. Does the problem happen with the snorkel disconnected? --Tanuki Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 16, 2012 Share Posted July 16, 2012 Could be a sign of a blown head gasket. Are you losing water? Quote Link to comment Share on other sites More sharing options...

vulcan bomber Posted July 18, 2012 Share Posted July 18, 2012 And yet I did a head gasket a few weeks ago that had gone at the back of number four and between two and three... chugged a bit but lost no oil or water and didnt struggle for power.

Engine overhaul will be required sometime. Possibly you should get the compressions checked - that will show if your engine is on its last legs or not.

Gaz13 Posted July 20, 2012 Share Posted July 20, 2012 Hi Had issues with White smoke about a year back after coming back from Billing , tried a few things, but turned out to be a fuel injector or injectors, changed all 4 and it cured the problem.

CLANCY Posted July 20, 2012 Author Share Posted July 20, 2012 Hi guys thanks for all the possible causes.Will get a compression test done, she's done only 130,000 Turbo make a noise need to check that as well. Quote Link to comment Share on other sites More sharing options...

Frax Posted July 28, 2012 Share Posted July 28, 2012 My 300tdi white smokes for about the first mile of running and then its fine, does look bad on start up, head gasket was done along with timing. Runs fine - I thought they all did that, pump tweak probably does not help. Have you just got yours or has it just started doing this ?

CLANCY Posted July 28, 2012 Author Share Posted July 28, 2012 Hi Guys Update the turbo makes a whistle sound with air intake off, sounds like a Supercharged Sports car turns heads (But thats not helping me with the problem).If I blow compressed air in the turbo intake puff of smoke and all's fine, run like a dream and starts all day long. Me thinks it's a air or Turbo issue.?? Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 28, 2012 Share Posted July 28, 2012 Blocked airfilter or a delaminated flexy pipe is where i'd look next. Quote Link to comment Share on other sites More sharing options...
Snagger Posted July 28, 2012 Share Posted July 28, 2012 Sorry for the hijack, but it is related. I get increasing white-ish/pale blue smoke at idle; the longer it idles, the more smoke I get. It seems pretty clean at higher power, though, and a short drive will clear the idling smoke unless it idles for several more minutes. It is burning oil, and has done ever since I built the engine up - it had a recon head when I bought it, but I had the block rebored myself and had the injectors and pump overhaulled professionally. I suspect the valve guides and seals, given that oil consumption is also worst when idling or when the engine has been on the over--run for long periods. What do you lot think> Quote Link to comment Share on other sites More sharing options...

CLANCY Posted August 2, 2012 Author Share Posted August 2, 2012 Hi Guys another update,The intercooler in & out pipes are sucking in when revving up,I put a screwdriver under the rubber pipe air rushes in and runs OK. Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 2, 2012 Share Posted August 2, 2012 Sounds like you either have a blocked inlet pipe between the intake and intercooler or a seized turbo. Quote Link to comment Share on other sites More sharing options...
elbekko Posted August 3, 2012 Share Posted August 3, 2012 The cause of your smoke is cold cylinders, my 200's the same. I've been having the same lately, smokes heavily once when I'm at the end of the street, and then it's fine until the truck's been sitting still for a few hours (aka engine has cooled). It started after I did the timing belt a few weeks ago, the timing was spot-on, so I doubt that's the problem. I also noticed it was hardly there when it was hot out. I'm also having head gasket/cracked head/cracked block issues, so perhaps that has something to do with it, but still... Quote Link to comment Share on other sites More sharing options...
CLANCY Posted August 7, 2012 Author Share Posted August 7, 2012 Hi the final update, and a big thanks to you all for your advice, Vulcan Bomber advice was spot on,The 90 degree hose bend from the Turbo to the intercooler had delaminated on the inside wall, a small hole in the outer wall let the air in between the two layers creating a balloon effect blocking off the air flow.That simple but so hard to detect. Bye the way the cost of the little bend £52 Regards Trevor Quote Link to comment Share on other sites More sharing options...
