How can I diagnose a blown head gasket? Maybe LIM gasket?
Here'* my problem. I just put a new water pump on the car about a month ago. After I changed it a few days later I noticed a small puddle of coolant in a small crevice on top of the water pump. A mechanic told me my pump was leaking. So, I tore it back down and cleaned everything up real good, put on a new gasket. Now, the little puddle is back.
While I had everything apart i noticed the previous owner rigged the wrong hose for the bypass hose above the water pump. The hose that seems to go to the pump then into, maybe the manifold? That hose isn't shaped correctly and was forced into position and has a kink in it. I thought, maybe that kink is causing pressure and forcing a leak but i couldn't see where anything was coming out.
Today i took the car for a drive to make sure it'* still running good after the new gasket, and new crank sensor and when I got home, I popped the hood and the sun just happened to be shining just right so I noticed there was coolant on top of the engine around where this hose connects.
My logic tells me that the kinked hose is causing too much pressure and possibly a leak. But, I am getting a little worried that maybe a head gasket blew? Maybe the Lower intake manifold gasket? There is no coolant in my oil. The oil looks good.
Obviously, I'll go with the new proper bypass hose first. But, if the problem persists, how can i diagnose a LIM or head gasket problem? Or, might something else be my problem?
Thanks in advance. You guys have been so helpful so far and my car has recently ran into several different problems, i don't know what I'd do without your advice. I'll tell ya as far as car problems, when it rains, it pours. Story of my life.
