I just did the first part of unflooding engine (steps until atf trick) and the first cycle of 20 seconds went smoothly, lots of gas fumes came out. The second time, i turned the key and engine started making this horrible screeching sound, so i stopped immediately. Im assuming this means engine is unflooded, but now im worried i might have fucked up an apex seal. any input would be appreciated.

 

It is the engine, and not a belt pulley? You would know if the apex was gone because the car would run like crap and sound like an old VW beetle

 

engine has yet to turn over since i bought

 

didnt sound like a belt, but it was in the drivers seat, so the sound could have been distorted.

 

Oh, the car wasn't running yet? Could it have been your starter slipping?

 

im not sure, i waited a good 10 minutes in between the first time cranking and the second time cracking, so the starter motor could cool down, the starter was in surprisingly good condition when i checked it when it wasnt on the car, so i would hope it isnt slipping
