new to this.91 talon?

[91talondsm]

have 91 talon tsi 2wd. think i have leaky head gasket so i did a compression test, here are the resaults. 164psi is normal and 121psi is service with no more than 14psi between each cylender. i had cyl.#1 160psi,#2 155psi,#3 155 psi, #4 160psi. my problem is that when i get on it hard i start losing all my coolent out the resavoir bottle and its boiling water,but doesnt when i drive it normal.also when the car cools down it spits lots of coolent out and doesnt suck the coolent back up from the o.f. bottle when engine cools. when i start the car on a hot day it blows some drips out the tail pile and white smoke i dont think its condonsation, it will smoke for a while then go away, if i turn it off for a half hour and start it up it will drip some water again with white smoke then after driving will go away.i tryed to see if it was the thermostate and pulled it out. and saw the water swirling around, so i dont think its the water pump.oil presher is at the first line when warmed up and goes half way between both lines when driving.so i guess my question is why is it blowing coolent out overfow with that good of compression?and could it be a head problem with that good of compression? its completly stock with k&n thats it.please help

Are you sure its just coolant? If its boiling too much it may be water thats in there.

[91talondsm]

well its 50/50 coming out

Mine was acting up when I made the mistake of just running water. Water alone is not enough to cool the engine, thats why I asked.

no im running coolent, had hole in intercooler but fixed it, and all the vacum lines were re routed to stock specs.

it had i couple small bubbles in oil a few days ago but it doesnt now.

K, well then I would suggest that the length of the hose leading to the cooland reservoir is too short. But the engine doesn't overheat though?

it only starts to overheat when i loose all the coolent.

the line to o.f. is very short thow

[JoeShmoe]

I would say replace it with a longer one. Thats a quick fix, but hopefully that would rule that out.

[91talondsm]

ok but with that good of compression could it still be a leaky head gasket, cracked head or block?

[JoeShmoe]

I really wouldn't know. What engine are you running?

[91talondsm]

2.0 16 valve dohc turbo

[JoeShmoe]

Well mine is not boosted, and its a 2G, so I really wouldn't be much help.
