new to this.91 talon?

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.

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.

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.

it only starts to overheat when i loose all the coolent.the line to o.f. is very short thow

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

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

it only starts to overheat when i loose all the coolent.could it b head problems or cracked block with that good of compresion thow?

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

2.0 16 valve dohc turbo

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

k thanks. if i stay on this tread will other people answer too? like i said im new to this

will other people reply still on this tread? like i said im new to this

Yeah, most definately. Its early today but later on you will probably get more hits. Jsut maek sure you update your signature with your car specs. You know, model, engine, tranny, mods, etc.

k thanks.

Rightous

still need help. thanks

It still could be a possibility that your head gasket is causing the problem. Since you only have problems when you are driving hard and boosting the motor the head gasket could be leaking some under high cylinder pressure. Its also possible that the head could be cracked or even slightly warped.

Thats really the only thing I can think of that would cause this problem. You might just want to go ahead and pull the head and replace the head gasket. That way you can also check the head and the block to make sure they aren't warped or cracked.

k thanks, should i do a leak down test, since my compression is good a compression test only tells if the valves and seals are seating right, right? a leak down test should tell me if theres a ring or head prob. right?

You could try it and see if you can find out anything. A compression test will tell you something isin't holding pressure, a leak down test will give you more of an idea whether its the valves not sealing or the rings are shot.

The problem seems to be only occuring at high cylinder pressures so I doubt you will find anything.

my heater also dosnt work if that helps. blower dont even come on, i see people talking about the heater core what u think. the thing is, is that when it cools down it dont suck the water back from the o.f. bottle it just stays full.

So the fan doesn't come on to blow the air inside the cabin? That wouldn't be the heater core.

the outside fan kicks on, but no , no air comes out the vents at all

the outside fan kicks on, but no , no air comes out the vents at allim probubly talking about the a.c fan the 1 next to the rad. fan that 1 kicks on no inside 1 thow

im probubly talking about the a.c fan the 1 next to the rad. fan that 1 kicks on no inside 1 thowwell i didnt mention that when i bot the car it had a manual boost controller on it and was pushing 20psi for a few pulls but wasnt losing coolent. it was running rich thow and vacum lines were all routed wrong . it didnt start blowing coolent out till i did the timming correct. when i bout it the exaust cam was off a tooth and a half so i did the timmimg, import auto works said the timmings right now.
