Oil overflow

Which engine? Dry or wet sump set up?

 

The air box breather hose connection comes from the top of the separator. You can disconnect it and plug the filter intake hole as it will suck unfiltered air in. Then re-route a new piece of hose into a new catch tank which you must make and fit.

The gearbox breather as std is a spring loaded capped metal hat on the bell housing. You can rip off the cap with pliers and run some 10mm hose off the spout into the same catch tank, which you need to fit to the baulkhead somewhere.

You can make the catch tank out of an old plastic bottle if it's only temporary, but a nice aluminium one will not break the bank. Just get a local fabricator shop to do it.

If you set your oil level carefully when hot, to be 20mm over max, you won't get oil surge and you wont get oil blowing out the breather either.

Drive the car until the oil is hot, stop engine and dip straight away. Set level to be 20mm over max (a bit less if you add lots of cold oil). Run the engine again and re check the level.

Then enjoy your track time. Check the level after every 30 minutes of track time.

25-30mm over max on a 308 and you'll get into danger area with oil blowing out the breather.

 

Phil, I've slept since I last looked at the parts book, but wasn't there also a factory change to the sump pan that happened on newer cars that helped with the right turn oil starvation issue? I want to say around 1979/1980 MY.

 

I thought it was in 1986...it was called the 328.

 

328 did not fix the problem. The internal baffling is the same and from observation there seems to be no difference in starvation. The only fix was the drysump.

Do as Phil suggested, re the overfill. Short of a dry sump conversion it is the best you can do.
