Default Blown head gasket?

so i think i have a blown head gasket but im not sure. i have a 2006 tc and its boosted well the other day i was driving and i was going about 35mph shifting into 3rd and i looked behind me and i saw a ton of white smoke comming out of my exhaust.... and on my way back home i tried to get it to put out more smoke and it did twice and there was a little the 1rst time and like none the 2nd time but i got home and opened the hood and my coolant was a little below where the low line is on the reservoir and my oil was below the low line and i had check my oil about a month ago and it was fine

well could be turbo seals. but if its motor i would do a compression test to just make sure your rings are good and do a leak down test that will tell you if the head gasket is blown.

Is your oil milky/frothy under the filler cap?

White "smoke" Can be caused by a lot of things. It could simply be cold out and the condensation mixing with the cool air in the right light can do it.

Your car will burn oil, its a fact of life. These car's are known for burning a fair amount. Is the car over heating at all? Thats the 1st way to really tell a headgasket. But for now you might just want to watch the levels closely.

Add a bottle of oil and check the levels. Or physically check the gasket yourself.

i haven't drove it more than 500 feet sense it happened but when i start it, it takes about a second longer for the engine to catch than it use to and right before the engine starts i dont know how to describe it but it just sounds different doesn't sound like its as clean of a start. and i would check the gasket myself but im not comfortable with messing with the timing chain and really messing up the engine

all you need to do is run a leak down and a compression test those two things will tell you exactly what and where your issue is..... if those come out great then its your turbo

Now that i had time to take a look the oil under the filler cap was normal and there wasn't any oil I'n the coolant but i did do a pressure test and it dropped 2 psi I'n 5 minutes and started blowing out smoke when i started it and idn y there is but I'n the cam brether i think that's what it's called but there is oil and coolant going from that to my turbo intake and the oil is milky there and that's the only place that there is milky oil.... I'm going to make an appointment with Toyota to get a diagnosis because me and my friend were both confused by the oil I'n the cam breather

Are you saying you did a leakdown test? Just do a compression test

Leak down test does not pinpoint head gasket a compression test does

Thats to check if your leaking coolant from anywhere including your radiator. You need to do a compression test

it won't hurt any to put better studs it.
and use an OEM head gasket, and nothing else.

So I pulled off the head the other night and coolant was in all but 1 of the cylinders I looked at the head gasket and there was no cracks or brakes in it? I have no Idea how this happened but my friend says arp head studs will fix It and I don't l know if he's right or not.

check if the deck surface on the head and block is within spec. ARP head studs should help a lot along with a OEM headgasket.
