Hello All, Ive seem to have myself a bit of drama with my 32. The engine is freshly built, but pretty much standard apart from splitfire coils, pods and an exhaust. I've probably done about 400km driving since building the engine and it was running fine but now it seems that the car is running very rich, blowing black smoke and kinda hestitating while just cruising but really lacking the power when I get on boost. Since this problem has arose I've checked all the cooler pipe and cleaned the plugs because they were fould up and I'll be swapping the coils over today to see how that goes. Has anyone had a similar problem so I can try to isolate the problem. Any help would be great.

Cheers

Check the (ECU's) coolant temperature sensor to make sure it's still telling the truth to the ECU. It's possible that one or both oxy sensors shat themselves. This is especially possibly if you used a non oxy sensor safe silicone to do any gaskets when you put the motor back in.

Also if using a standard ecu, bridge the wires and see if it shows up any codes. I had a similar issue and turned out to be the AFM playing up. Pretty common for 32's and been that you've just done some work on it may have been hit or so during the work. All it takes is one dodgy wire lol

It's all sorted guys. Turned out to be the twin turbo pipe gasket. But I checked the codes aswell and turns out my afms were stuffed so I've fixed those and it's running sweet

      R33 GTR lift points for hoist

      By sunsetR33 · Posted

      Hi all. I am aware there is lots of discussions about jacking points, where to lift the car and what not. But as usual just a lot of "in my opinion" and nothing definitive, and everyone does it in a different way. I want to hear from some experienced people on which points on the car it's okay/safe/recommended to lift the car using a four point hoist/lift. I will attach some images of my underbody. Sills are largely okayish, the driver side jacking point is pretty mangled though and it looks like the underfloor is slightly pushed in too, but I might be wrong. In the German Skyline forum, the consensus is to use the sidemember chassis rails in the front and the rear subframe? bushing in the rear. I know the manual says to never use the sidemember for loading but lots of folk do it and it was definitely done on my car too as they are slightly bent too. Based on the images, what points do I use to not make the already present damage worse? I'd use wood or rubber blocks to spread the load across a bigger area of course.

      Ticking Sound On Idle - Rb25

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Ticking Sound On Idle - Rb25

      By GTSBoy · Posted

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers
