Oil smoke from left side heat exchanger

[domtoni]

Posted this in the engine building forum, but didn't get any response. Any ideas?

Hi All,

Its been a long time since my last post. My car will be 49 years old this year, 73,300 miles.

Oil drips from left side of engine into the heater box and under acceleration, smoke comes into the cabin. I've tried leaving the heater off, and venting the smoke to the outside of the car, but even then, smokes comes into the vehicle.

Does anyone make a device that can be installed between the engine and the heater box to prevent oil from entering the heater box?

Otherwise its an engine re-build.

Thanks
Dom

Pretty common if car has been in the garage for some times.
Do not install anything, just drive... heat will burn oil into exausts and smoke will stop

Get under the car making sure both flaps are fully closing. Oh, and see if you can fix the leak.

BTDT...

Oil get in the HE (where the 3 pipes enter the chamber) and once a while it flash over.

I took them off, clean them with soapy water (dawn) and put some high heat silicone at the joints.

Of course, as mentioned below, fixing the oil leak (probably from the rockers, $3 per seals) is the permanent solution.

Thanks guys. Will have to take a look.

Ciao for now

If you don't smell oil, how would you know you drive a 911?
My brother always said "if there is oil in it, there is oil on it"
