  1. I don’t need it anymore so you can save big$$ All you need to buy are the inserts! User for: Cadillac Pre 2000 Northstar 4.0/4.6 V8, First Repair General Motors AND NorthStar 2000 V8 General Motors Cadillac & others This kit does all!M11x1.5 Headbolt35mm upper bank and 51mm lower bank. This is measured from top of the block to the first starting thread. 35mm thread depth used on pre-2000 engines! $299
  2. From what I have hear, Norms are better because they have a coarser thread pitch, which is what GM eventually went to in '04. Just finished a Time-Sert job on mine! TIME-SERT J-42385-2000 Northstar Kit up for grabs!
  3. Time-Sert Job Complete! TIME-SERT J-42385-2000 Northstar Kit up for grabs!

  4. Time-Sert job completed! Also have my TIME-SERT J-42385-2000 Northstar Kit for sale if anyone is interested $299...
  5. I think that pretty much confirms it. The head gaskets themselves rarely go. It's the bolt threads that pull. Insert all 20 bolt holes even if the threads look good unless this time is just for practice. I would also recommend that you either stud it (northstarperformance.com) or use Norms inserts (ebay). Both have a coarser thread than Timeserts. I'll look into norms inserts, had not heard about those. Thanks! Do you know if there is a DIY with PICS for dropping the cradle? I will be dropping this week. Thanks
  6. I am currently looking for a used kit j-42385-500 now also! I plan to drop the cradle and do the repair by 8/14 so if you have a kit I will buy asap at a reasonable price. Thanks!

  8. I was hoping that was the case with the A/C, and ABS. I bought the Napa test kit yesterday and confirmed the combustion gasses in the coolant (yellow liquid) last night. I will likely be tackling the head gasket/timeserts next weekend. Appreciate the help.
  9. I have a 97 SLS with an overheating problem reported by the previous owner. Ran a block check and confirmed leaking head (Yellow fluid). Also performed pressure test and have small leak from side of RAD at 15lbs. Pulled all plugs and #1,3 and 7 are fowled and wet. No oil in water or water in oil, so I assume it is at least a head gasket and possibly the infamous head bolt issue. Top hose get hot way before it should (180deg, so I also need a thermostat. The car does not begin to steam out the exhaust until the engine is completely warm about (20 minutes at idle)and coolant temp is over 215deg. I assume the head bolt issue is causing the leak because the heads appear to have to be hot before separation occurs. If it was just the gasket I would expect it to steam much quicker. My question is, are my assumptions about the bolts reasonable and should I go ahead and order the time certs? Also, do I need to disconnect the HVAC/coolant to drop the cradle? Any DIY on that particular piece would be great. Thanks in advance!
  10. Hello all! Just bought a 97 SLS for resale and need to do the heads. Looking for any assistance with DIY instructions for dropping the cradle and timeserts or studs.
