Customer Question

My question is, could a high pressure oil leak cause 0 icp pressure during cranking on a vt365 2007 international. My bus doesn't have any injection control pressure and the bus wont start. I'm trying to figure out whats causing this and how to fix it. I don't know if there is an high pressure leak, I'm just asking for possibilities. thank you

Hi I'm Wayne

I will help you with this

Yes high pressure leak would cause low oil pressure for the ICP

remove the valve cover , crank it over and see if you see oil pouring out

it is very common for the o-rings to leak

I hope this helped you

I forgot to mention that after long cranking the ICP got up to 20psi. What is another way to check if the HPOP pump is working correctly.
