hi everyone, i have a 70 gs with a 350....about every 10 days or so i am down about 2 quarts of oil...i took it to two mechanics who say the oil is not coming from the motor...they checked the rear main and said they let it run for 1/2 hour and not a drop there.....the starter is covered in oil however, nothing coming from valve covers...does anyone know a mechanic in massachusetts that can take this car and fix it...please, somebody has to know what is going on...
If oil is on top of the starter, you have a leak from the valve covers. A 2 qt loss is a massive leak. Best bet is to pressure wash the engine and use some Castrol SuperClean to remove all oil/grease residue. Once you run the engine after the cleaning, you will see where it is leaking. I would suggest you use FelPro rubber valve cover gaskets and not the "el cheapo" cork gaskets.
George, Thank you, I will try that tomorrow but like I said, we could not see anything there...I will pressure wash the motor and clean it and let you know how I make out....Either way I will change the gaskets and see if that helps.. Thanks, Steve
Steve Also check your oil sending unit..mine was loose not to long ago and was leaking pretty good. ..just snuged it up and all is good now...
Thanks Bill, I will check the oil sending unit also...If the problem still persists then I will check back for further advice....thanks for all the help steve
valve guides and/or seals ? i had a 710 datsun (pos), new in 1975 that after 25000 miles , used a quart of oil a week . it needed valve seals . sold the car before making repairs .
With worn/missing valve stem seals or worn guides, you will get a "puff" of smoke upon start up or after shutting down the engine and restarting 10-15 minutes later. Also, with bad valve stem seals, you will also have fouled plugs due to oil contamination.
