How many miles on engine?. What color smoke? If white clouds of smoke that goes away when it warms up that indicates a possible housing seal. Another symptom would be having to add coolant. view this video -> https://www.youtube.com/watch?v=4H-B1nckyFE

Hi, I have a 2005 hilux 3.0 turbo Diesel , it started blowing blue smoke at startup from cold at 130,000ks . Once it warms up a little it clears.


There can be several reasons for this. You can have worn valve stem seals on the valves, which may change with warm oil, or you have worn oil rings in the cylinders.

A compression test when the engine is cold would reveal if the piston rings are worn. Another possibility could be a bad head gasket which leaks oil when cold and then seals when the heads warm. A compression test would also diagnose this.

1995 Oldsmobile 88 LSS 3.8 smokes at idle


Valve stem seals. Oil is thicker when cold (hence no smoke when cold) Vlave stem symptoms are when engine at idle (high vacume) oil is pulled through the guide seals, when you take off from lights get bit of smoke until oil is burnt. Ring symtoms is it would be blowing smoke all the time especially at higher rpm for extended time ie: driveing. Have you thought of trying a thicker oil? what oil grade do you currently run?

Suspect valve stem seal caused smoking after being idle, replaced head gasket set and p'rings,t'belt, plugs, oil & air filter as there was no service history at 66,000 miles. fired up fine...


If it only smokes after you crank it up and then stops after it warms up usually that is the valve seals letting oil leak down in the cylinder after you cut it off .

hey that sounds familiar!have you checked your idle control sensor? let me tell you 1st you crank it cold,you have to keep your foot on the gas pedal until it warms up.but then when you come up to red light quick stop,the engine dies or wants to stop? sometimes it starts fine? but when it does,after running for a few minutes,it idles up and down? when it's warm after driving 15miles or so,you shut it off and try a restart,and the engine starts,but idles up and down? all of the above are signs of a bad idle control sensor.the part costs about $20.00 u.s. 2bolts removal 1 PLUG IN REMOVAL you may be able to do it yourself.have an autozone or advance autoparts store employee show you where it's located.you would be shocked at how many great people there are left in the world! i'm answering your question for free at midnight from the u.s. think i'm bored? no. just love helping people like you! thank you so much!

I gotta floor my 1992 bronco 5.0l to crank it


white smoke? Thats an indication of water getting into cylinders. May have a small head gsket leak. Metals expand when heated which explains why it stops smoking after warming up. Have some one pressurize the cooling system when engine is cold, and search or listen for leaks. Pressure gauge on tester will drop in pressure if leak is present.
