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

      Nope, but they are definitely one of the default choices. Well established.

      Haha actually I did join back then under a different email address,  I couldn't re-activate my account so made a new one! I didn't post much anyway so not missing out on much. Amazing to see how the value of the cars and parts has changed over the years, also ACT section appears to be dead now.

      Thanks... It's in pretty good condition overall, probably due to not being drifted/tuned however being a daily driver has taken its toll. Had 100k on the clock when I got it, up to 180k now. Unfortunately it's not 100% dent free, it's got a small dent on FLH side and broken indicator from where I hit a small kangaroo at high speed. If you look at closely at pic #5 you might spot the dodgy trailer light repair my old man and I rigged up as temporary repair! - It's still there due to a combo of needing the car as daily driver and then too lazy/busy to fix properly. I've a couple of other minor accidents accidents as well but nothing major. One required a new front bar and unfortunately the smash repairer ordered the normal gtst one and not the aero bar. Needed the car back asap so just went with it, regretted ever since.

      How "plug and play" is the Haltech Pro for R33 GTST

      I can't believe that anyone is foolish enough to believe that the base maps are for any other purpose than to drive the car up onto the trailer/truck or gently creep it to the dyno. No matter how good they are, they can never be any better than the factory maps**, and only the foolish trust those on a significantly modified setup. **Yeah, yeah. I know there's also the difference between factory maps being fixed to certain injector sizes and MAP/AFM/VE relationships, and the likely aftermarket ECU base maps being better able to handle the sorts of changes that would render a stock ECU dangerous, like different sized injectors. But let's just ignore that for the moment, because the principle is still the same.
