24volt

Do you think this is a leaking turbo? I was told to get a catch can and it should prevent this from happening. However, when I installed an Intercooler, the hose from the intake crossover pipe to the turbo had some oil residue. Thanks!

I have 2 batteries connected parallel for a 12 volt set up. I am told my batteries are bad. Since I need to replace them, what is the proper battery specifications for a 12th engine? Thank you
