guys! anyone here familiar with car papers like ORCRs?

i have an ae92 sedan and the papers got lost like years ago. but the car can still be registered. i still have the affidavit of loss. problem is the engine (4af), its really in a bad condition. its been tru a lot of abuse. BLOW BY is the term i think, or almost . i dont consider rebuild coz i think it cost a lot, ewan.

the main question is, can i still do the engine swap without the papers? are there any alternative? any means? is it ok as long as i have the engine's papers can i still proceed? sayang kc ung kotse eh. balak ko talaga e 20v ST. it will be a daily driver sana. can anyone help?

tama ba lugar ng post ng tanong ko? dito na dapat? hehe
