Hey guys,

Replacing the crank in my 26/30 currently. Some of the bores have very light surface rust. I want to run a bean hone through the bores to clean them up, question is do I need to replace rings when doing this also? The current piston/ring setup has less than 1000k's on it. The CP ring packs are like $150 each, ill do it if necessary but I'm just not sure.

Will de-glazing the bore with a bead honer effect how the current rings have bed?

Cheers.

I should have probably been more specific, I'm running a bead hone through just to take some of the light surface rust off. The flex hone tools are specifically for de-glazing, which is just why I said that. It was run in correctly with proper run in oil and varying revs. I dare say I would have had significant blow by had they not have been, for which it had zero when it was running and made really good power. Literally the only thing that failed was the thrust.

Cheers anyway Kiwi. I found the ring packs for $50 each, so I'm going to check all the clearances and chuck new rings on again anyway. What's $300 on one of these engines, I just can't see how they will seal properly again in my mind if I try and re-use the old rings after flex honing it.

      It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣

      R34 Skyline Sunroof Won't Tilt/Vent

      By ShezzDogs · Posted

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!

      Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.

      Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler?

      Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed
