I can hear the oilr gurggle by as it goes to the front oil cooler!!!

I have a 1982 911SC...and when my engine is warm (thus thermostat is open) I can hear the oil burrble and gurggle by under the passenger's foot well...

does anyone else hear this...sometimes it is loud...

I thought there was air in the system so I ran the car without the oil cap...but no change...

So is the oil cavitating in the system?
do I have obstructions???

thanks

MJ

Look under the car make sure the oil lines
are not pinched.... If they look ok then
the gurguling should be no problem.

This is completely normal on a 911 with a front cooler. It even happens on the 993. It can get pretty loud at times.

It happens to mine after start up when I park over night on an incline, nose down.

it happens to a lot of them after a fram oil filter is installed.

I've never heard that in a 911, and my current 911 doesn't do that.
It don't know for sure, but that doesn't strike me as "normal" behavior. I can't see why there should be any air in the lines near the front of the car. It seems it should be a solid flow of oil, which would not make any "gurgling" noise. Esp. on an SC, which has just the trombone loop.
I do hear often hear the oil as it is being dumped back into the tank, but that is a sound from the tank, in the back. But you sound like you are describing something different.

Interesting comment about the Fram oil filter causing noise. I know for a fact that certain oil filters can be noisy on their own. The rattle made can even mimic tensioner and chain noise. Last year, I used two German made filters sold by Pep Boys and
both rattled. It could be heard from inside the car. Changed to the OEM and no noise.

I had a Fram on ly 911 once. It gurgled loudly. It was removed in less than thirty miles. I use only Mahle now.

The oil cooler line gurgle happens too, but not as loudly as that Fram filter did.

You should be happy you hear gurgling... my t-stat is stuck and no oil gets to the front cooler and no gurgle ;(

Your real problem is that the muffler is far too quiet! Rev the motor up a bit higher and listen to the "music" it makes and press on!

I just did the Heat Exchanger back date so I think the muffler is plently loud...

it doesn't happen all the time, I think it is when the oil is at a certain level, and maybe pulls some air as it is pumped to the front.

Did you look under the car , maybe its your mother in law .

there's a mouse in your oil line

I had a new '82 - it gurgled just as you say your car does. My present '87 doesn't and I don't believe my previous '85 did either. I think it's just a normal deal on an '82.
