Crushed Oil Line Question

[Koizumi]

Oil temp seems to be normal at 90F ambient outside with the needle hovering around the first gauge tick. With the AC on in obnoxious stop & go Friday afternoon traffic, it gets close to the second gauge tick. It never reaches the 2nd tick but it gets close.

Oil is BP 20w-50

I've got the older Carrera oil cooler in the wheel well, the non-fan version (and obviously not the silly trombone style).

I have the typical partially crushed oil line near the jack point issue. I'm wondering if this partial crush is an issue. My oil temp is always at or slightly below the 1st tick with no AC and 80F ambient outside. AC and hotter ambient temps push it up to near the 2nd tick in stop & go traffic as mentioned above.

What do you think about this crushed line and should it be repaired ASAP or are my temps normal for the ambient outside temps?

Replace it and get a fan on the cooler.

Your pipes are bit worse than the small dent in mine, but your temps sound totally normal to me, assuming your gauge is reasonably accurate.

[wayne robson]

My opinion is the partly crushed pipe is not a real problem
so changing that wont make any difference.

[Bob Kontak]

There is a thread on "popping" out the dents with air pressure and a propane torch.

I would not fret the temps but do some research on pulling the lines in your leisure (this will be the hard part) and then configuring the pressure system.

I'll find the link and post.

Here it is:

Fixed my Crushed Oil line for $5 and a beer.

You do not need to replace and add a fan. I and a ton of other people are in the same boat. I myself am in the same situation and have not had any problems or issues with the temp, even in the summer here in Cali.

Thanks for the answers and suggestions. At this point I'll wait on it. My OCD will eventually get the best of me & I'll try out the propane compressor technique. Seems easy enough. The endless summer heatwave continues onwards here....

You dont NEED to, but its definitely worth the minimal expense and time. Up there in Sonoma is a bit different than down here with LA heat and traffic. My 930 has one of these set to turn on about 205f

Is adding a fan to the oil radiator a straight forward project?
I'd be interested in making that upgrade if it's commonly accepted as good.

Is the $160 link above the only game in town?

That's the most bolt-on straightforward install, but piecing together a kit is easy. Just an electric fan of the proper size, a thermoswitch, and some wire.

It's so commonly accepted as good that porsche installed them after 1986

K,

Just pop it out, take care the brass is really soft. I used a bicycle pump. Worked until I burned throw it, used copper pipes and soldered it and held up fine until I got the finned lines and their fan . Definitely cooler.

[sugarwood]

At $160, it does seem expensive for what it is.
What do you think piecing a kit together would cost?
I will look for a thread where someone's done that.

[Koizumi]

Out of curiosity, would a fan install help cool the early Carrera non-finned tube cooler (not the trombone style). I thought about adding a fan but my cooler isn't finned so I'm not sure if it would make much of a difference.

[DRACO A5OG]

My 2 cents. It will help but very little as the area of the older cooler has less surface area to cool it down adequately, but it will help, especially stuck on the freeway parking lot. Flow is what is critical, better the flow faster the cooled oil can get back into the engine to do it's job.

Maybe a aux fan in the engine bay?

Side note, how is your AFR, if on the lean side it will burn hotter??? PM me and I will explain.

[sugarwood]

To answer the OP's question, I have rarely gone near the 2nd tick.
Then again, I don't seem to drive in stop and go traffic, nor do I turn on the AC, nor do I drive when it's crazy hot out, either.

I would still get an estimate on repairing it, just for the peace of mind.

[Justin@Athens]

I will say that in my 964 the fan does a very good job keeping the temps under control but if the car gets too hot--the fan will not bring the temps down. Many 964 owners install a switch for this very reason. If you encounter a situation where you know airflow will be reduced for an extended period, you can switch the fan on BEFORE the oil becomes too warm.

Does your "Normal" range of 190-248F apply to my mag case 2.7L with SSI?

[Koizumi]

Mine never gets above the 2nd tick. It gets close on days of 95F and stop & go with full AC. Under normal circumstances, it sits at the 1st tick... 80F, no AC

I just pasted that graphic from another thread.
