White fumes out of valve cove Breather

[lowresolution]

Guys ,
A friend is having the following problem .

* This problem happened just after he took a 1/4 mile ( its a 4efte , td05 with all the supporting mods )
* White fumes are coming out of the valve cover breather
* The car starts fine but missing is there before 2.5k RPM . After that its fine .
* The car is making boost / power after 2.5k RPM easily and runs fine .
* We checked all of the vaccum hoses , and they are connected properly .

What could be the problem ? The engine was recently build with OEM parts 4k Kms ago .

Broken rings/ringlands.
Not tuned how it should be? What boost was he running?

Compression test it?

he`s running around 1 Bars . The car was tuned fine and was giving out some good results . We are trying to get hold of a compression tester to see what are its results .

Compression test and cylinder blow by test, sounds like a land

Only at 1 bar, its sad

Sad but true . The guy shift into 5th at around 80km/hr and kept boosting it till 180-200kph . Can this be the cause ? I heard some where that its not a good practice to boost like this !

Lack of fuel possible, never heard of engine load causing that, well to that degree

Sounds like bad fuelling and timing.
And also if the block was worn.

Sounds like poor quality fuel, whats the fuel like you get over there? Have to remember that stock and even plug and plays are designed to run on Japland octane fuel.
