2G low compression all cylinders

[diamondsm]

ive done my research and i am stumped so hopfully i can get some help i will add every detail i know

1995 eagle talon tsi

i bought the tsi (running but with a blown head gasket) i tried to drive it home the car started smoking and over heating i pulled over, shut the car off let it cool down tried to start it and nothing so decided to tow it home....got it home took off the head took it to my mechinest they told me it was warped past repair....i then got a used head off CL took it back to my mechinest had it surfaced, presure tested and 1 valve guide replaced(i broke the valve with my home made valve spring compressor) i put all new exhaust & intake valves in.....put the car back together and it would not start i thought it was timing i timed it 3 times thinking that was off......then i did a compression test


resaults of test ( car will not start so could not warm engine first)

30psi 45psi 90psi 30psi (first test

30psi 40psi 95psi 35psi ( second test thought i did the first test wrong

40psi 50psi 105psi 60psi (third test put half cap of oil in cylinders

40psi 50psi 110psi 70psi (i removed all spark plugs and turned it over to blow out the extra oil from the third test before trhen did fourth test


i then took the head off again and inspected it (i thought i got hydroloc in my lifters causing the valves to not completely seat, i replaced the hydraulic lifters with new 3rd gen lifters put the head back on and it still would not start......i then went back to timing ....timed it about 5 different times by the book every time i cranked it 6 rotations and the marks all lined up ......did anoher compression test

35psi 60psi 35psi 58psi


i then removed the head again with the head off the car i turned the cams by hand and all my valves are seating

so to break it down new head presure checked and surfaced new valves new hydraulic lifters new head gasket and no compression??

valves i got were new but i got them from a frien..... he said they were stock valves
i was also thinking my rings maybe but i have even compression across the bored my last test? the cylinder walls have a little bit of build up but no pits or scaring


could all my rings go at once from over heating?
could valve hight cause no comprssion even if i can still get all valves to seat?
could weak valve springs cause no compression?
could it still be timing?


any help is good im stuck if im not online you can txt me 360-640-9653

alright so i just decided to go with a rebuild kit off ebay (new pistons,rings,bearings gaskets ect) i took the block to the mechinest after honing and ridge reeming it he said everything was good and to order standard size bearings pistons ect.


so heres the problem i got it all put back together and it wont start i have spark, fuel, compression everything is plugged in i timed it out of the car so i know thats perfect

here's some things i was wondering about

i got a new cam angle sensor could it not be adjusted right? if not how do i do that?

could vacume lines cause it to not start??

anything will halp im yet again stumped

When you have a head milled does that not change the geometry of the timing?

Would this require a sort of adjustment in the timing marks to bring it all back into phase just like you would when degreeing a set of cams?

I am dealing with this exact same issue but it is with a head that has been milled many times. So I am thinking that although the marks are aligned the timing is off. Think 4g64 with a 4g63 head and gears.the taller deck needing to change the gears but opposite.

as seen here but i am thinking of doing it the opposite direction due to it being shorter.
