Oil shooting out of Dipstick?

[robw13]

My 74 Charger SE 360 has Oil shooting out of the Dipstick bout 10 sec after running getting it everywhere. Believe the PCV is still good. Any ideas?

massive crankcase pressure.. Usually means you have an issue with compression gasses getting past your rings.. I may be wrong, but that has been my experience...

I concurr with "Pistol"

Just do a Compression Check to verify/eliminate this as the culprit.

MOPAR 360 CI:
Look for: 130 to 160 psi per cylinder.
Uniformity is best.
NOTE: below 100psi is a problem, compression is allowed to leak past rings and fill oil pan.
Eventually building up pressure (Much like the many pumps it took you to pump up your bicycle tire with "hand pump" as a kid)

Finally, unable to slowly release; the crank case "Burps" the built up gas/oil mixture out.
It takes the shortest route; the il dipstick if the seal is weak (At dipstick)

I just drained the oil and it had 8-24qts! It smells like oil & fuel but the stuff is 20yrs old. One of the worst smells I've been near.

 

[Photon440]

Smells of fuel? Then either a lot of gas is washing past the rings and into the oil, or your fuel pump is leaking into the block.

I think super-bee_ski is right, I would be doing a compression check and go from there.. won't cost anything if you have a tester, if you don't, worth while to get one...

and it will give you a baseline as where to go from there..

 

[super-bee_ski]

BTW,
ROB, what do you mean by 8-24 qts.?

Are you stating it has 6 gallons of oil?
4 quatrs = 1 gallon
8 quarts = 2 gallons
24 quarts = 6 gallons of oil...

Please clarify..

 

[robw13]

Sorry typo, I've got a 15qt jug and its full now. Bout 8-12qts went in.
Compression. Test reults:
Cyl 1, 5, 7, 2, 6, 8 = 120psi
Cyl 3, 4 = 95 psi

 

[pistol_grip_polara]

sounds like #3 and #4 are the culprits.... probably have to pull it apart

 

[robw13]

True, probly be better to replace it. Not sure if its worth rebuilding.

 

[Photon440]

What kind of pan are you using that lets you put 12 quarts of oil into a 360?

I think he was saying it was a mixture of oil and fuel..

 

[krowbar]

Find out why you have so much gas in your oil first. #3 & #4 are probably washed down and you're loosing your compression from that. Are those two cylinders firing?

 

[monaco66coupe]

I bought a coronet with the 383, and it about 12 quarts of oil and gas in it. So much that it wouldn't crank over. the PO had been trying to start it for days and days, flooding it. I drained everything, fixed the starting problem, put in five quarts of rotella, and started it up. Ten minutes or so later, it straightened itself out. low compression, but I drove it for a year until I could rebuild the correct engine for the car.

 

[Dako]

It must have read very high on the dipstick prior to draining it...

I would put 5 qts of cheap oil back in (maybe along with some Sea-Foam or some other inexpensive additive) and see how she does. I mean, if you were willing to run it before, why not now that you figured out it was simply over-serviced? A 360 is a good motor to just toss. But hey, it's your money.

 

[badmopar67]

Did you mean when you said 20 years old the oil has been in the motor for 20 years ?

 

[robw13]

I dont really wanna toss it but would like to fix it. I drained the oil/fuel mix and added a new filter & 3qts so far just to see if there were any leaks. Do I just add seafoam into the crankcase? Never used seafoam. U think a head job would fix it?

 

[wedge69]

Seafoam is a good prodcut But will Not fix a Mechanichale issue !
Squert some oil in those cylenders with low compression and see if it comes up some first. Then go from there. you say # 3 and #4 so I am taking there on opiset side's of the motor and not side by side ?

 

[pistol_grip_polara]

You can try a few "quick" fixes but doubtful anything will fix it for more then temporary.. I tried this with a 360 I had.. Ran fine in one car, pulled it out, stuck in another one a year later, and talk about a smoke show.. I tried varios remedies with no change whatsoever..

Finally pulled it apart.. had one broke ring, and when I took it the machine shop, I took in my block with a set of .040 over pistons.. engine builder told me that if I had shown up with .030 over pistons, I would of needed a different block, it was that worn out. Told me there was no way it was running.. yes it was.. I have lots of witnesses.. It was pumping oil out the drivers side tailpipe as fast as it was going through the motor.. but it was running!

best to pull it apart or get a different engine

 

[robw13]

Yes, the fuel, oil, Trans & coolant have sat for bout 20yrs. Would it be best to take the whole engine to a machine shop or how hard is it to fix the lower block?
