RO Posted November 20, 2012 Share Posted November 20, 2012 Unable to remove oil pan from the car w/o dropping a lot of steering components but I want to try and clean the pan out best I can after a blown head gasket occurred. What is the best thing I can use to pour into the oil filler cap, perhaps sit a few moments, and then out the drain plug? The drain plug is at the rear bottom and the car jacked up.Thanks Link to comment Share on other sites More sharing options...
Guest Neil Larson Posted November 20, 2012 Share Posted November 20, 2012 Hi, I have been in the auto several years. When we would get a car in, that hadn't had the oil changed in 10K miles, and it was so thick, it had to be coaxed out with a screw driver... We used to put a quart of ATF in, run for awhile, to loosen up the oil, drain, and then put mostly atf in the crankcase, and warm it up. Do not rev the engine, just let it idle and warm up, drain it again, and you may have to do it one more time, depending how the oil looks coming out. Put a new filter on it. and run..Hope this helps.

Coley Posted November 20, 2012 Share Posted November 20, 2012 Why not just ues a crank case cleaner?ATF has no detergent action in it. Link to comment Share on other sites More sharing options...
RO Posted November 21, 2012 Author Share Posted November 21, 2012 I will be running the ATF or kerosene through a number of times without the engine running. I want to get as much of the stuff out of the oil pan as possible before ever attempting to start the car. Once we get the car restarted, then I plan on rapid changeout of of the oil and filter several times until the dipstick and oil filter canister look clean. That's why I wanted suggestions of what to pour in the oil cap, let it sit for a few moments, open the drain plug and then do this several times. We already had mysterious chunky looking swampwater come out after just five or six gallons of old oil being poured through. Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted November 21, 2012 Share Posted November 21, 2012 RO, I don't know what the car is, but removing the pan will be the best. Seems what you are planning will get costly. Plus, there is probably a pickup screen on the pump suction that "flushing" will not clean. Tell you what, you drop the pan and document the process, and I will do the one I have been dragging my feet on. Bet both will be way ahead.
