I'm needing some advice on installing my rear main seal on my fresh rebuild. Erl dry sleeved Ls7 with procharger @ 10lbs. I've researched and called a few vendors on what orentation is best on these engines with boost and no solid answer. I never had any issues with the old style seal (lip facing block), but they are discontinued. I've ran across several posts of people installing them backwards(new style seal) due to leaking. Need some advice or experience asap, I'm installing the motor friday. Thanks!
