im looking into to buying a 91 240sx its got a sr20det and its got rod knock?????...new to this

rod knock in a nut shell means you'll be needing a new engine.

think so it only does it when its cold start and wen it revx over 3 grand

if that's the case then rod knock might not be the problem but rather lack of oil flow/pressure.

k thanks so what woulkd i have to do to fix this problem oswap out the oil pump??? im looking to buy it its gonna be my first car

Please do not double post.
