1990 Cherokee 4 L str 6 cyl
after shutting my jeep down I ve heard liquid moving. I decided to find the source. it turns out that I was hearing the oil draining back into the pan.
I was under the jeep with my ear next to the pan, no doubt of source.
this lasted about 15- 30 seconds before stopping. the front of the jeep was raised about 6", as I had parked it that way.
is this concerning?
I was recently going to change my valve/rocker arm cover gasket, but decided to wait because it did not seem to be leaking and I did not want to use the inexpensive cork fel pro gasket that I had bought, I decided to wait until I could afford the more expensive gasket.
I did notice thru my oil fill cap that there is a lot of crud under the cover and I am concerned that my oil return drains are partially clogged.
how can I clean these drains when I do change the gasket? since it has been strongly recommended here that I do not disturb the crud I m not sure how I should approach this. could vaccuming the loose crud with a shop vac be okay?
ps. dropping the oil pan is not an option right now because of the extensive labor involved on this model and the expense of all the new seals and gaskets required. I ve bought 200 bucks worth of parts and fluids this month and it will be awhile before I can afford more.
right now I have brake shoes, tranny filter and fluid, above gasket, oil and oil and fuel filters waiting on me to work on, and other non mechanical things.
to summarize my questions…
- does noisy oil drainage concern you?
2)how can I clean oil drains?
a. can I pour kerosene thru to clean oil drains, and to help flush oil pan, which I can t drop right now?
b. can I shop vac under the valve cover?
c. should I add sea foam to oil for a bit before changing?
