85 engine noise
 

:help:im about to buy a used 85 supra and the seller stated that it needs new lifters and that it makes a ticking noise when u give it gas and at high rpms. he also said when i drive it home, i should drive slow and he got an estamte saying 800$ to fix. i called a shop and the guy said each lifter is like 80$ and id have to replace all of them. Ive also read on mutliple forums about marvel mystery oil. is this somthing i could fix myself (im a chick whos never really tore an engine apart lol) or somthing ima have to spend 800$+ for? D::confused:

the engine looked like a 2.8 v6
