How did you test it?

Could be a HG failure.

hey man i had same problem but try flushing out the radiator sometimes , silcone and rust gets blocks the fins in the radiator and create pressure build up when u turn off the car ..... jus try flushin the radiator

Whats your temperature sensor showing? You probably could use a thermostat.

well if you can afford it REDLINE is a great synthetic proved a 25whp gain in a WRX....just by using all redline fluids over stock

I am an engineer who designs lubrication systems for a living everyday and I will say this:
Royal Purple is the only oil we do not reccommend and will void our warranty. The seals used in our systems are automotive engine seals and the royal purple attacks them - especially on older seals that are used to regular dino-oil. My educated .02 - stay away from Royal Purple - the benifits are not worth the risk.

BTW - my 4th gen swap loved M1 15w50 for the turbo engine. just don't use it on newer engines - stay with 10w30 or 10w40 would be even better. Turbos need thicker oil as they cause the oil to break down faster. or just more frequent oil changes which costs more.

I know Castrol Syntec is usually cheaper than Mobil here. I used to use Mobil 1 synthetic and it was a huge difference in smoothness over "dinosaur oil". Now I put in Castrol Syntec just because its cheaper, and the bottle is a little easier to pour.

Really any synthetic is great, but if you can afford it get Royal Purple. Its supposedly lightyears beyond anything that petroleum companies selling synthetics are making....much more durable and protective.

I use 5w/30 fully synthetic oil for mine.
But your being a turbo engine, I would
go with something thicker.
If you have castrol over there, I'll recommend that

I've always used Mobile1 fully synthetic. You can feel a noticeble smoothness to it over regular dinosaur-oil.

10w-30

yea, the conditions you discribe sound like normal condensation.
can you get a pic for us?

When you say you have had the headgasket checked, do you mean a compression check? water and white scum inside filler cap is normally a sure sign of the dreaded BHG (Blown Head Gasket) how does it drive? does the temp rise when you boost then drop when you cruise along off boost? if the answer is yes then it is a BHG I'm afraid. Blue smoke = Oil 99% of the time, is it using a lot of oil?

if its just TRACES of it, its normal, just condensation.
are you sure the smoke is blue when you rev hard? if so, could be a number of things...tired turbo, rings ect...

I put 20$ of premium gas (93 octane) as usual and had my car washed at Shell.
I drive for 15 mins... stop the car for about 45 min and after when i
start it again the engine is rattling like crazy and theres white smoke coming out of
the muffler. The idle is very low (below 500), the engine shakes alot, smells gas alot.
No apparent leaks. Fortunately, I was able to drive the car to the mechanic shop 2 corners away
but ill have to wait till monday to know whats the problem.

I think the water jets under the car at the car wash might have shot some water in
my gas tank cuz there is some rust spots around.

What do you think?
