1G Eagle Talon 92 N/T 2.0 stock

[Yoan Yordanov]

Im 20 years old student and
Here is my story...

I bought this Eagle Talon last year. I didn't drive the car because i had an oil leaking and i had to change the semering with a new one. Once i have done that car stopped leaking oil and i started driving it.
I drived it about 1 and a half month and one day i decided to try to test the car i can get up to the 120 MPH speed mark and then what happend.......
I was in 3rd gear 1k RPM and kick down the trottle pedal and the car glitched on 4k rpm with the gas pedal to the metal and could get above 4k RPM then i let the trottle off and drove off to the next available street corner and i stopped the car to poped the hood. The car engine stared shaking and working on 3 cylinders.I checked the oil stick and engine oil was on the minimum , then walked to the nearest gas station to buy 10w40 oil and i was sipped about 500ml then the oil stick was on the maximum. I started the car and it was the same ( shaking engine and working improperly). Before all that happend i was doing the key thing that when you get to higher RPM's and turn off your car and start it again, your exhaust pops and i did that soo many times. Back to the story...
i drove off the car to my place, and after month off , my car was chilling in place i decided to checked the spark plugs, cables and the injectors and the problem wasn't from them. Yesterday i opened the camshaft head cover and removed the spark plugs to see how's the pistons doing. And as what i saw, pistons from 1st cylinder and 4th cylinder they were fine, but the pistons on 2nd and 3rd cylinder had something like black recess on the top of the pistons.I checked the compression and the results.... 1st and 4th cylinder had compression and 2nd , 3rd had no compression. So my question is :
Did i lost the commpresion with the key thing that makes my exhaust pop?
and if you have any ideas how do i fix my engine , leave a reply please ...

Head gasket went out. Check for oil in the antifreeze or antifreeze in the oil (a milkshake looking mess).

nope... head gasket is fine and oil and antifreeze didnt mix

Skipped timing, bent valves is what it sounds like to me

 

[1990TSIAWDTALON]

I would have thought that to Henry, but it didn't make sense only the 2-3 cylinders went but not the 1-4's. I will agree with that as the next problem, lord knows I have bent my share of them........

I've seen situations with only 1 cylinder bending valves due to valve float etc. It sounds like there was some rev-limiter action by the OP, so that's what lead me to think that. I could be wrong. Hard to decipher some of the info, so if @Yoan Yordanov could clarify what actually happened (I understand english may not be his first language) then that would be helpful.

If only 1 and 4 are firing I would first check the ignition system. plugs, wires and coil pack.

Edit: oh sorry I overlooked the last bit of info where you said you have no compression for 2 and 3.

A bore scope would come in very useful for this. You can also pull the valve cover off and probably tell by the difference in the valve stem height for a bent valve. A leak down test will tell a lot also.

He has no compression on 2-3, not just a no-combustion issue.

Agreed, more investigation is needed. Pulling the valve cover for a look would be the easiest assessment, A leak down should tell all.

I opened camshaft cover and i dont saw problem with the valves , and also checked all cylinders with a bore scope , but i didnt see any problem again.
I tryied also lifting the car on a jack and started spinning the wheel to see the valve action, and i noticed that at the top dead point on the pistons and lowest dead point, was getting harder to spin (felt someting like studder). I think that is all from my researches, and hope you will understand more.
Im ready for more questions to answer.
