My 2000 silverado z71 vortec 5.3L 186k have a small leak in back of the motor, found 1-2 drop of coolant stuck bottem of the oil pan. I lost coolant but not much, my coolant level alway stay at cold mark, when cold or hot it alway stay at cold mark, if I add more coolant, it will drop down to cold mark after drive for day or 2. My reservoir never ran dry.
This reason why I think head gasket
on the other thread where I ask about milky/steam water under the oil cap, since I drive very short trip 10min a day and if I wipe milky stuff off and I drive long trip and get on highway often no more milky stuff under oil cap, and I check back next day after yesterday long trip, no milky stuff. but still see steam water stuck under oil cap after long drive ( I dont know if my pcv system is working correctly, im using the new update pcv from dealer, where it does not have anything inside the pcv , it just have a very tiny hold at the bottem of pcv ( mabe I should try the old click type pcv ).
Thing I already check, oil on dipstick look brand new still golden color and in correct level. No smoke in back exhault and no sweat smell. no bubble inside the coolant reservoir , truck idle and run strong. Never over heat, the temp guage alway behind the middle mark, middle mark is 210, so I guest around 190-200.
I went to autozone to do the coolant pressure test, my coolant cap say 15 psi, I pump in 15 psi and it hold pressure. I saw the leak in back, but cant tell where its. Take to my mechanic and told him what going on, first thing he say is heater core slow leak. Then I pop the oil cap and he saw couple steam water stuck to it and steam water stuck on the fill neck he say it look normal, but not that much condention. Then He have to go, so I take the truck home and park. I dont plan to keep run the truck until I have enought moneys and time to ready fix what ever is wrong with it.
When im ready , im thinking take to dealer and let them check what going on. cause I dont have any shop in mind that I can trust. Any one know how much dealer charge to check for leak and tell me exactly going on ?
on the mean time, if you guy been in same situation or similar, can tell me what happent, if it head gasket, that is ok for me, I will fix it when I have moneys, mabe next month or so, I have plenty other car to drive. Im not worried or stress over it too much
