Oil out of dipstick

[midwestLTD]

As it states in the title I have oil coming out of my dipstick when it's reved up.. (driving rpm's). My Dad used to call that blow back! If true it meens my rings are shot & one of my pistons has a hole in it.. Maybe the oil pumps going bad???? Hope its the pump cause I don't have the $$$ for a re-build!!!! Please someone prove me wrong... PLEASEEE!!!!!!!

SBFs are notorious for clogged or partially clogged PCVs. Make sure the PCV system components are clean and working properly. You didn't state the mileage or otherwise the overall condition. If the car has a broken ring or a hole in a piston you'll like get a noise or excessive fuel consumption or another clue like a skip. Make sure your thermostat is working properly as a cool or stuck open thermostat will sludge the oil and not allow the engine block to get rid of "sweat". This moisture gets mixed in the oil and can clog the system rather quickly.

+1, check the PCV system. It is blowby, but all engines have it to some extent. If the PCV stuff is working correctly and you still have this problem, do a compression test and see what it has to tell you.

Miles are around 100.000 not really sure as the odom stopped working at 68.000 on me.. Vic has been running fine just reg. maintenace stuff due to age has been done on her. PCV is all new I had a problem w/ the grommet that holds the PCV in popping out a month ago or so. Put new one in so far no blow out there. Will check the thermostat tomorrow. Gadget will do a compession check.. I did't mention that she doesn't smoke; w/ the exception when I get on it. Thanks for the tips Gents..

Hate to ask but you did change the screen as well as the grommet and valve?

Can't help it. Had to also respond to your comment about your odometer stopped working! Mr. Ford ought to be horse whipped More proof that a larger statistical sample reveals quality issues and is another reason reading these posts and belonging to this community is advantageous for a Panther owner. My 90 odo stopped working before 130K. WE are not alone.

The 90+ cluster is well known for dead odometers. The plastic gears crack. You can get replacement ones. They lasted 10-15 years most of the time, which is long enough as far as they care. If it helps any, the 80s models don't seem to have this problem

No I did not .. That is one thing I left out.. It looked ok so I cleaned it out.. I know it's such a cheap part but at the the time part store was out of it & she is my day to day driver so I had to get it up & running when I re-place the upper intake gaskets.

Ok so that is one thing to change.

Is the oil level correct? Not way overfull.

Funny, not so funny, story. I gave a friend with a Mark VII an oil change with Mobil 1 Extended performance (1yr/15Kmiles) oil. Three days later he was hospitalized so his son started driving the car. He actually checked the oil. Determined the car was out of oil and put in 4 quarts of some regular oil. I get a call from my buddy in the hospital to the effect that the fancy new oil did not work and ran right through the engine or out the plug or filter. Three weeks later I check the oil and it is WAY up the dipstick. The only thing I can figure is that the new Mobil oil was so clean that he could not see it on the dipstick so he dumped in 4 quarts on top of a full engine. Guess the $35 oil and extended performance filter were ruined as the next change has to be in 3K instead of 15K miles now. Also the son refuses to believe there was oil in the car and is still convince I messed up somehow, though he offers no explanation as to why the car was so overfull.

Also when you change the filter, check the vac on the PCV hose.

[gadget73]

The level marks on the dipsticks sometimes are not accurate. If you don't know them to be correct, next time you change the oil (5 quarts with filter) pull and mark the dipstick where the full mark is after you've started the engine to get the filter loaded up. I had one that full was considerably above the factory full mark. The factory mark was about a quart low.

Well the Thermostat wasn't it. OIL still coming out of the dip stick.. Checked compression the old fashion way by putting finger in all spark plug holes. Had it turned over on each & it pushes my finger out so I think compression is good; but my buddy has a set if gauges so I'll let that tell me as well. Jaywish by vac on PCV you mean the valve itself or is there an actual pump at the end of the hose underneath the intake pendulum?? I replace the PCV valve.. One of my friends is a mechanic he said it could also be the oil pump going bad. Will have to do a pressure test on the oil as well. He did say that I might be able to put SEAFOAM in my oil run it than change oil & filter again. Might have some sludge on the intake of the pump screen?? UGGHHH!!

[jaywish]

The vacuum is supplied by the running engine. (pistons going down on intake stroke). It is siphoned off the intake for the pcv. I was suggesting you remove the hose from the pcv, run engine and check vac by holding thumb over the end of the hose. Vac should be fairly strong. When you remove thumb engine should run bad.

Also, the PCV screen....

[gadget73]

Make sure that screen isn't clogged up. If you didn't replace it, replace it. Its usually clogged solid and the PCV system does not work at all.
