rebuild install thrash

Well it all started with the blown trans ( 9-11 ), this meant pulling the engine, repairing the trans and putting it all back together in time for a show 10-3. While out the engine received a new oil pick up, and a re-install of the rear main seal. That's where we pick it up, a new and correct distributor gear, re-checking all the timing and the re-install of the front cover.

So it was the day before the big show, I opened the shop and prepared to start the car again, this time for a complete run up to temp checking all fittings and the engine . The engine was snappy and all the gauges temps and sounds fell right in place, with no air circulation the water temp stabilized at 190 thanks to the installation of the new oil cooler. I peaked under the car and , WHAT, a oil leak! No it wasn't from the engine, in fact all those prior leaks were gone, but after a lengthy inspection I found the culprit, the sending -10 line to the cooler. I pulled it apart and the fitting that screwed into the sender had a bad oil ring, no big deal I just wend down to my local Napa and bought another, trouble was the original was so smashed it was not comparable to the new one, I took the oil ring to the shop and hooked it up, It leaked!
Back to Napa, guess what they had another that was bigger, it leaked! it was now 5:30, panic,
no fix till Monday! I missed the show, all because of a little ring. Sometimes you just have to say, theirs a reason for what happens, and move on, their will always be another show, their will never be another Pantera for me.You f*#%ing little oil ring!!!

I recommend viton flurocarbon rubber for o-rings that are in contact with hot oil. Even harder to find are pure teflon o-rings. Hardware store o-rings may be neoprene rubber and those will not reliably seal hot oil or fuels.

Also, sealing a boss with a threaded plug normally requires a sized chamfer on the edge of the threaded hole. With a chamfer of the right size, the o-ring is forced into a triangular cross-section that squeezes the o-ring inward against the plug threads as well as tightly against the outer edge of the hole. Without a chamfer, the o-ring will be smashed flat and often splits, again causing leaks.
Your right on all counts and as before the A&N -10 viton oil ring is listed.

I feel you man.

I was planning on attending a car show in Petaluma yesterday.

Went flying with my Dad to a small air show in Livermore, planned to spend an hour there and be back by noon, but we accidentally parked with a bunch of other Ercoupes (seemed like the place to park, with all the other like planes), little to realize we became part of the airshow, and weren't allowed to leave til after 4PM. Now that sucked, I missed the car show, I really wanted to show off my baby.

The ride home was crazy too, windy and bumpy as it gets, fun day all in all though.

Waiting 5 or 6 hours to leave sucked.

also just went through an 0-ring ordeal, after installing it, I then took the fuel rail back apart to put a Viton O-ring in, just to be safe, so I did it twice.
...Next time Go Aeroquip -10 AN Hoses and Fittings. NO 'O' Rings.
But then, you have to know Exactly how to assemble the Fittings Correctly.
There is Only ONE Correct way to do it, and it takes training and practice.

And I look at Your Blessings! Fate kept you Off the Road! You didn't break-down on the side of the road, With Nothing Open on the Weekend! You weren't HIT! And you weren't involved in an Accident! And the Cat wasn't Stripped or Stolen because you had to leave it, to locate parts! Do you have AAA? And would you have had your cell phone with you?
NO HARM was done! Just Disappointment! As They say...'It's Not the End of the World, Just an Inconvenience'.

In Your Excitement, Good Thinking you Looked Under the Car, and Didn't just Fire It Up , and 'Take-Off'!!
By the way, Chris- be VERY careful with driving those 180s. I found the sound to be SO seductive, I was always going 20 mph faster into corners than was best just because the sound was so nice- especially around 6000 rpms! I consistently stayed in the throttle too long just to hear the music. Pretty sure the brake pad life and fuel mileage suffered horribly because of those wonderful pipes!
