Re-check the fitment of the PCV oil canister pipes at the top. A recent post on the subject of continued pressure turned out the poster had switched the 2 top pipes in error. Reversing them corrected the issue.

Like the guys are saying, if the problem wasn't there before you took stuff apart, then the place to go is back over the area you worked on and around the area you worked on to see if anything got broken or damaged or missed on re-build.

The PTC element is of no consequence; something else is at play here.
So the mechanic came to check it the other day and tested the compression. The car indeed did have some compression and was as follows: cylinder1: 95, cylinder2: 98, cylinder3: 110, cylinder4: 130, cylinder5: 120. Not quite exact but about how much i remember-ish. The mechanic found that two ignition coils went bad and i replaced tho's but no luck. The car will not start.

The mechanic also checked for codes and no codes were found. Only other stuff apeared on his obd device like bad convertible motor, bad windows etc. i do remember i saw something about bad timing apear on his device. I asked him about that and he told me to wait. But he never told me as i forgot to ask him again

Get some oil into thise cylinders and crank for 15 seconds, rest for 30. See if you can get some firing after three such cycles
