Timing tensioner stud snapped - Boo

The other night my RB30DET suffered greatly. Thought I ran out of fuel or something. Filled it up and nothing.

 

The question:

  • RB30e bottom end
  • RB30ET 20thou down pistons
  • RB25de neo head

Interference or nah?

 

Am replacing the stud, taking cams out and putting it all to TDC. Hoping for the best.. If not, new head I guess :(

Has anyone else had timing issues and got away with it? Do you fancy my chances?

If it's a neo head you'll know if you've bent valves or not by just putting some feelers between cam and lifter. Standard gaps are something in the 0.010" range, if you've bent a valve you'll find a lot more than that gap.

PS - I don't like your chances.....

I'm not certain about rb30 hybrid, but all other RBs (except apparently rb20) are interference.


Where did you hear that RB20 isn't an interference engine? Surely it would be the same as all other RB's

I can tell you first hand the rb20 is interference 




lol, I did say apparently....source is unvalidated information I picked up on here sometime over the years....

I also know there interference. Yet I'm interested if your experience has anything to do with your user name

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
