aux oil thermostat removal
has anyone else had the pleasure of removing the external oil thermostat on their SC? While back dating my heat exchangers and oil lines, I completley distroyed the threads on the external thermostat. Finding used one without bad threads is a challenge. Does anyone have a method of removing attached oil lines without pulling the threads out. Thermostats are darn expensive.

Good luck. I had to cut up the oil line from thermostat to engine then the thermostat to cooler lines were seized, then the thermostat sheared so had to get another one, plus both cooler lines plus both lines from the thermostat!!!

some where in one of the porsche catalogs, i don't remember which one i saw a special fitting the goes on the therostat body that will give you new threads. I think you know what catalogs i am refering to, the ones with the purty color pictures, sorry Wayne.Check with one of the guys aat Pelican ,maybe they can get it for you Jerry

on the really tight ones, an air powered disc cutter can be used to split the nut to relax it's grip on the threads. cut almost all the way thru, and then split it with a hammer and chisel. if you nick the threads, no big deal, as the sealing is done by the mating surfaces of the two pieces, not by the threads.

I took the entire oil line assembly out of the car. Broke the connections at the hardline, oil tank and front trombone loop. You can then get the thermostate into a vise. Used lots of PB Blaster and heat. It took awhile but was able to remove the lines without any damage. Need a good wrench combined with a cheater bar. Good luck.

John and Bruce are on Target. John's is a last resort. Bruce's plan worked on 2 of mine. Lots of PB Blaster and heat.
BUT DO THE MATH before you cut. Both front oil lines are $300 + a piece. Both back ones are $70 a piece. Thermostat $350. The oil line ends are harder than the thermostat. The thermostat savers are $30 a piece from Wayne and Tom here @ Pelican. Thermostat Saver, 911/911 Turbo (1974-89) [Photo] PEL-PP901687 $29.50 I cut, because I'm Aeroquip plumbing to my oil cooler up front ( PO squished one line with floor jack and had a farmer patch in the lines to the oil cooler ). And the line from the tank to the thermostat had a hose clamp ( farmer ) repair. ( Don't want the line to come apart at a DE event and ruin everyone elses day ). But John's plan works great. I used a Dremel to cut mine. YOU DON"T FIX THESE WITH RUBBER AND HOSE CLAMPS. My farmer repair came apart and I lost 9 quarts of oil in 3 blocks. Thank god, I was driving a back street at slow speed. Scary part, no loss of oil pressure NO LIGHT. Just watched the STUPID oil tank gauge drop like a dragster fuel gauge : )) So get it out the car and soak it with PB Blaster. BE PATIENT. Let it work. If that doesn't work. Then do the math and make your choices. Good Luck ------------------ Cary Kutter 77 Euro Carrera w/3.2 PCA Region - Big Sky |
