decent price that jake, but your a trek away from me, probably cost me that in fuel with the shite consumption im getting.

ill go the compressor method with tennis bull... proper pikey style

jake or someone, when leak testing, ill bung the tip, use 5psi-10psi owrth of air, i need to block the tip off where the pcv lines goto into it dont i? open the filler cap and is that it to test for leaks?

will this test all the pipes under the manny etc etc???

cheers

James theres no need to test the tip, block off the charge pipe to turbo hose and pressurise through the n75 feed into the valve. 10 psi is plenty and this way avoids pressurising the turbo.

Mine was done through the Tip carl...

ive fitted my new Maf today and the old maf was full of oil...Im thinking its a crank breathin problem tbh...Doesnt seem to be that bad now the more and more i drive it..

but id lik to test the tip for leaks around the turbo also...

surely if pressured to less than the psi the turbo boosts then it will be fine??

we test through the tip as it the does the full engine, our machine doesnt even go up to 1 bar pressure iirc as turbo seals can and have been gone in the past.

Right ive been driving it and its fine...But today when i really wanted to play in it...and came to a idle this happened..

Now this only happens when the Turbo is red hot...ect creating lots of boost and dosnt smoke even wen cruising around and playin with the boost only when i come to idle....

This is the smoke im getting....

Video:

So im guessing turbo? as it dosnt do it any other time not Cold start Up,Engine breaking,Driving Normal,Normal Idling in traffic,Creating small amounts of boost Even creating Full boost it doesnt do it..But if i go and do 4-5 sprinted runs so its dead hot it will smoke on idlee..But let it cool down for a hour then start it back up and drive it no smoke at alll...

Why don't you go and get a compression test, or do it yourself?

If that is clear, then the next port of call would be looking at the breather system?

warm up engine for the time it takes for it to start smoking,

Disconnect fuse 28 to starve the engine of fuel and it will die

remove all spark plugs

depress trottle when cranking to do test

if test results are down put a teaspoon of oil in each cylinder, if it rises it is the rings, if not it is the valves

Id be there all week then as it doesnt smoke on idle...if i go out for abit and do some major runs in it and get it red hot it will smoke..

thats what im sayin it only smokes when its red hot...If i drive it 20miles normal driving it wont smoke with various driving styles..

but if i give it death and come to stop idle it will blow smoke.....(SO IT ONLY DOES IT WHEN IVE GAVE IT DEATH ECT HIGHER UP IN THE REV RANGE ECT...)SPRINTED DRIVE ECT

Thanks Mark.

What am gonna do is just take it to a garage and let them sort it...I can't be arsed with it doing it all in my spare time...

Took it to someone today and he point at the turbo being at falt he said guessin the seals have been disturbed and once the Turbo gets hot the oil get slightly thinner causing it to seep through...He also checked the Plugs again and said that the oil isnt getting burnt inside the cylinder....

But im gonna take it to a vag specialist tbh and pay the £££

To be honest I would do something simple like a compression test myself, I have been too many garages with a good name only to have them be a bunch of fitters and not mechanics!!!

i would'nt put boost type pressure thru tip personally..

hmmh... well i may go in through the chrge pipe top then.... so to confirm anyone, if i clamp the charge pipe off feed the air in there will this test all vaccum hoses under inlet manny etc for leaks?

what kind of pressure should i put in through the charge pipe hoses?

also can pressure testing this way test any exhaust components for leaks?

cheers
