Hi, i have a 72 914-4 with a freshly rebuilt 1.7 case and crank shaft w/ big pistons and cylinders. i have been having a massive problem w/ the engine leaking excessive oil first i fixed the hole in the dipstick tube( machine shop bent it when i got my case worked on) then figured out that the thermostat pulley had to be on. On fixing each of these the oil leak has been decreasing as each got fixed, but on the side of the engine w/ the pulley it is still leaking too much to drive it regularly. the oil drips down on to the exhaust and produces quite a bit of smoke. I was wondering if anyone had any suggestions about where this mysterious leak could be coming from? it is not coming from the push rod tubes from the best that i can see. i have dropped the engine about 4 times trying to resolve this issue and hopefully some one can help me with this problem

The valve covers tend to leak, take a picture of the area that might help us identify where it's coming from.

Check that your oil pressure sending unit is tight and not leaking. Its located under
the distributor. |

yeah ive been driving it around for the last day and a half and the smoking went away, so i'm glad that it finally not having major issues w/ oil leaking i'm thinking that either the valve cover gasket swelled or the heat exchangers just had tons of oil on them and it just had to burn away either way im happy that i can drive it again and thanks for the help guys

QUOTE then figured out that the thermostat pulley had to be on Are you saying that you had oil leaking out through the thermostat pulley bolt hole? Now that would be strange. I wonder if they all do that or if you have a flaw in your casting? Stu |
