Regular paper gasket with Indian Head or GasgaCinch on it. None of mine ever leak.

A fuel pressure check is in order. Perhaps the PO used an Airtex pump.

Check out the inventor's family's new stuff. www.torvec.com. Thanks for the reminder!! T1 is original Cross-Axis design. T2 is the Parellel-Axis design which was never realy a TorSen.

Where's the AFTER photo?

Nah. It's the plug itself that is too hot of a heat range. It retains it's heat and that's why the deposits are on it.

I don't think the plugs are causing your manifold gasket to fail, but those plugs look like they're definitely the wrong heat range.

That's what I was thinking. Ditch those pieces of crap right away and put some NGK 7252s in there.

Not the knock sensor. Not back pressure. What spark plugs are those BTW?

Gleason had nothing to do with the TrueTrac. The people who bought Gleason's patents "added" the True-Trac to the product line calling it a TorSen. The TrueTrac is a helical gear-driven LSD commonly referred to as a gleason-torson due the inventor of the design and its later maker. Although Gleason the man may not have had any direct connection to the TrueTrac the people who bought him out did. Gleason the company became Torson ( its long full name escapes me right now.) I have always heard ( that might be my mistake right there :hmm: ) that the TrueTrac was based off of a Torson modification of the original Gleason design. The later versions are referred to as a gleason-torson differential. I have had the cone-type LSD in several Mopars with the 8 3/4 rear. Their version is called the Sure Grip. I was impressed with their initial clamping power but less impressed with their longevity and that failures are for all intents and purposes catastrophic. They were originally a Borg Warner cone-type design that was sold to Auburn and which Auburn still produces. Mopar's car Dana 60 Sure Grips were actually the Dana Power-Lok clutch type LSD, considered by many to be about the finest clutch-type LSD design as the clutch pack is easily adaptable to fine tune the bias. Their discontinued Dana 30 Power-Lok LSD's were a factory option in the front of several vehicles and are still sought after for that application. 8.25 & 9.25 axles used clutch-type LSD's but were also referred to as Sure Grip. A factory LSD in an XJ with an 8.25 is a clutch-type. Sure Grip = Chrysler. Posi/positraction = Chevy & GMC. Traction Lok ( later unofficially shortened to track-lok ) was the most common Ford name. Dana's in house units were Power-Loks while Jeep primarily had the Trac-loc. Notice the very similar names for most? How Chevy's "posi" became the default norm for all LSD's when even Buick, Olds, and Pontiac had different names for their LSD's is strange. Especially when you consider that the other make's LSD's were mainly the exact unit that Chevy used. So to tie this in: The fact that Borg Warner designed a cone type LSD to which the rights were subsequently sold to Auburn in no way changes that today's Auburn cone type LSD is based on that BW design. Later enhancements were not made under BW but the BW design remains. The same applies to the TrueTrac. It may or may not be a child of Gleason but it is at least a grandchild. Benjy-26:Similar to your Blazer story I drove a '70 Dodge Super Bee with a 425 horsepower (via desk-top dyno) 440 and a spool in the rear for a full winter here in Ohio. As with your K5 all that I had to do was remember that it was there and drive accordingly. I did not realize that you and I were apparently displaying a skill that is unobtainable by so many others. Much clarification is needed regarding the Gleason Torsen diff and the inventor Vernon Gleasman. See the difference in names? Vern Gleasman invented the Dual Drive Differential aka the Triple-D in the 1950s. In the late 70s, they made me 2 one-off units for my Nissan Patrol. Early 80s, the Gleasmans sold their patent rights to Gleason Corporation in Rochester, New York. The original diff was a cross-axis design and was throughout it's time at Gleason. Gleason later sold the right to the Torsen to another company that had the rights to a Parallel-axis diff known as the Tru-Trac. That company .put the Tru-Trac parallel-axis diff under the Torsen NAME. As Keith Gleasman, son of Vern once told me "It's like giving your son up for adoption and the next time you see him, he's wearing a dress". Why do I know these things? Because I have been a friend of the Gleasman family for 37 years. I also worked for Gleason Corporation in sales and training. I have demonstrated and explained the original Torsen cross-axis diffs to the likes of Mickey Thompson, Andy Granatelli and Mario Andretti.

Gleason had nothing to do with the TrueTrac. The people who bought Gleason's patents "added" the True-Trac to the product line calling it a TorSen.

You sure deserve it!!!

Feel free to point folks to the link as needed. Should be much simpler now. Thanks for the kind words.

Correct. See #3 in the link in my signature.

Hornbrod (Don) was kind enough to assist me in indexing my Tips, with photos, in the existing link as in my signature. I know I interrupted his Miller Time for a few nights but he stuck with me. Now, folks can be directed to the appropriate write-up by number. Kinda like ordering Chinese food. Need to refresh grounds-#1 in the link. Set your 4.0 to TDC? #12 in the link. Yada yada. The index is right at the beginning. Enjoy.

Thanks gogmorgo.

Sorry, I don't. but there are a ton of them out there. I will post this in another section but just so ya know, Hornbrod took the time to organize all my write-ups, with an index at the beginning, numbered and with photos where applicable. Same link as in my signature will take you right there.

Looks like a 30 in front and 44 in the rear.....

Refurbish the NSS anyways. The contacts in the bulb holder of my climate control were spread too far apart.....

The vacuum lines under the throttle body on the intake manifold are prone to cracking. Also the intake bolts loosen up. Start there.

I don't have a diagram of the headlight wiring that I can post up. Perhaps Hornbrod does. Got a trailer wiring harness on there?

Me neither.

Oh yeah. I have an excellent memory. Just short.

!. Cuz you didn't know us before this. 2. Thought they were gonna save fuel. Didn't work.

Where are you in Northern Az?
