So it’s happening at all throttle positions, in the specific rev range. Taking it back to the shop this week to get the belt whine and squeal fixed, I’ll check in with him on further diagnostics for the ping. Y’all, I got ripped off with this Skyline. Paid $26K and was told I was getting a “turnkey” example. I know all the stuff I’m experiencing besides the knock is expected, but I would’ve expected that at this price point, most to all of these things would be sorted already. Feeling swindled.

Also - running 5W-40, was recommended by seller.

Sorry - RB25DE Neo, as y'all likely already know.

Hey y'all! In the latest of my un-luck saga, I had been hearing some metal-sliding/rattling noises at lower RPM under engine load/acceleration. Originally thought it might be transmission related since that was where I'd usually shift (I live in a slow neighborhood so lots of lower-rev driving). But, upon having a mechanic hear it, it turns out that I have a detonation issue. Before I got a timing belt service, this was happening in 1500 up to 3K RPM, but post timing belt replacement it's been down to about 1700-2100. I've been doing my damnedest to keep her above 2100 for most driving - little bit more jerky but I'd rather not lose an engine over this. So far: - replaced timing belt, timing retarded slightly as per mechanic who did the work... problem got smaller but not solved (as an aside, getting lots of belt whine and even squeal when I start her up in the mornings) - Been only using top-tier fuel available locally (91 is premium for my state in USA, since it's high altitude we get f*ed on gas quality. Been using Shell... but does have the "contains up to 10% ethanol" sticker, unsure if that's gonna be an issue and if I should seek out no-ethanol gas) - Plugs are BRAND NEW via the seller... maybe they did a bad install? RB25DE, 5MT. Glad to be able to actively control engine speed for an issue like this. Other than a bad MAF, what else could it be? Could the spark job have been a bust? Compression test came back 180 on all cylinders except one at 160... something questionable there?

You guys are amazingly knowledgeable and I appreciate it all so much. I’m currently at the local RB tuning shop, getting her inspected and diagnosed, for the t-case debacle and everything else. I’ll keep you guys posted!

Wow, didn't realize it was THAT much of a PITA haha. Can I potentially source an auto transfer case to salvage parts from it for a rebuild of my manual case, if it's FUBAR? Is it like [part set a=manual], [part set a + part set b = auto], or are they configured/engineered completely differently?

Appreciate it man, gives me hope based on my Google searches on availability of GTR parts. When you say I'm "not going to," is this in the vein of "who on earth would want auto," or more "it's impossible?" Not trying to be rude, truly don't understand haha. I know, it'd be a madman move to go manny to auto, but if it IS my only option, I'd be curious on the lift.

Update - new drop of oil noticed. Leak seems to be continuing, but a slow/small one.

Hey y'all! So I am the owner of a shiny new '99 ENR34 25GT-Four, 5spd manual. Took it to the tire shop to get new shoes. They mismatched the front and rear axles (225/40s on rear, 225/45s on front), so AWD system went bonkers for the next day. Took it back in, they fixed it, but I noticed about 8-9 big drops of red fluid in my parking spot. Leaking has stopped, but it's clear that the transfer case may have been stressed/hurt by this debacle. I'm taking it in for inspection tomorrow. If things are FUBAR, I have a few questions. - ENR34 manual transmission transfer cases seem impossible to source. Can a GTR transfer case fit? Or if not the whole thing, just seals or components? GTR is 6spd, mine's 5spd, so I'm thinking no, but lmk. - Finding a few RB25DE NEO AWD auto transmissions for sale, for decently cheap. If my only option is to swap to auto, what else will I need besides an auto-specific gauge cluster, and associated wiring? - I imagine the R32/33 GTS4 transmissions/transfer cases are a no-go? They're not NEO engines, so unsure. - RB25DET/4WD setup from the Stagea, any parts that transfer over? I did search up for this on SAU and google, very little info covered. This is my first post, so apologies for breaking any rules, please let me know, and thanks for the help.
