Re: Dark brown gravy for oil
 

The 8BA road draft tube crankcase ventilation system was a big improvement over older flatheads, but was still ineffective at low speeds and worthless sitting in the driveway "warming up"!
You need a good run at 50-60 MPH (or more) to get airflow past the end of the tube to pull crankcase fumes out while drawing fresh air in through the breather cap on the intake manifold. That's why it was called a "road draft tube"; you needed to go fast enough to get a "draft" going at the end of the tube.
This is just one reason a PCV system is so much better. It ventilates the crankcase even idling in the driveway!

Seems weird that we are talking about Subaru temps (granted it was current discussion lately)..... when it seems like you have choco oil.


Change the oil, see how fast you have coolant in the oil... It'd take a long time for condensation to make your oil into Chocolate milk.


Gas will just thin the oil. Not change the color.

If you get the oil figured out and still want to add stuff to the radiator I always had good luck using "Alumaseal". You can get it on Amazon, but a lot cheaper at Wal Mart. Chap

The numbers I posted are NOT correct for a 8ba engine! Those are 59a numbers.

Re: Dark brown gravy for oil
 

JS Do u know the correct ones 4 the 8ba?

Re: Dark brown gravy for oil
 

Checked Stant listings 13358 or 45358 both fit 8BA so I’ll have a couple as back ups.:)

Re: Dark brown gravy for oil
 

Yep, the 8ba is easier to ID as they had modern style thermostats from the get-go. Sorry about the 59a post, had a computer HD failure and wasn't paying attention!

Question: I'm Getting ready to change oil, run aluminum powder into cooling syst., & install stats., will the aluminum powder fowl the stats?

Re: Dark brown gravy for oil

Re: Dark brown gravy for oil
 

Oil changed, put stats in, put aluminum powder product in. Ran per instructions on aluminum powder sealer. Cooling over nite. Will test drive take long ride tomorrow and see if cured.

Re: Dark brown gravy for oil
 

Took a 1.5 hour drive today, kept the temp at 175 to 190, no sign of white smoke or bubbling in radiator. checked oil a few times stayed a nice light brown clear honey color. Problem seems solved but will check oil frequently.
Thx for tips & ideas.
