I was told that my 1953 235 engine required 5 quarts of oil.I am not running a oil filter and that is a lot of oil.It does blow a lot of oil out the rear seal when I drive 55 or 60 for a period of time.If I keep it at 50 or below it does not leak as bad. I remember 4 quarts and 5 if you ran a filter.But it has been a while. Thanks.

All 6 cylinder car engines from 1929 thru 1962 had a 5 qt. capacity..(except 1962 Chevy II and Corvair).
When refilling with 5 Qts. it will be slightly over the full mark on the dip stick.If the rear main leaks at high speed it will leak just as much with 3 or 6 Qts. in the pan.
The 1955 V8 was the first 4 qt. car.

Thanks for the quick reply. I guess I was hoping that the 5 quarts was causing my oil leak.When the engine was rebuilt they put a rubber seal and then I pulled the pan and put a rope seal in . It still leaks. The tranny will be covered with oil after a drive. If you remove the inspection cover it will have a pool of oil in the bottom of it. I wish I knew what to try next?

Mark, First I would be sure it isn't the valve cover gasket at the very rear of the engine, and running down the rear of the head... then check the welsh plug above the crankshaft behind the flywheel where the cam shaft is if the oil really is coming from under the inspection cover, of course that is a major tear down of the transmission clutch etc., etc.,
My theory is that a higher RPM more oil is getting to the valve cover and leaks worse than a low rpm, plus the fan blows it straight back...just a theory from Macky-Wacky!

The upper rope seal is very difficult to install properly with out removing the crank shaft.IF it was replaced it may have been "pulled" thru and srtetched out of shape-or-they left the rubber top half in place and put a rope seal in the lower half.The rubber seals are made for 1955 and up only.The seal groves are slightly larger in the 1954 and prior and the rubber seals usually fit too loose and leak.

If your 235 is a 1955 the rubber seal can be used.The top half of the rubber seal is easy to install.They are available from any parts house that sells FelPro brand gaskets (will be special order).
