Headgasket repair?

My R33 GTST has been leaking oil from the turbo side of the block. To me it looks like it is weeping from the head gasket. There is oil higher up but not as much as what appears to be coming out of the headgasket. I have just changed the cam cover seals, and will brake clean the oil off tomorrow. I have also noticed that my coolant reservoir I need to top it up every couple of weeks loses about 10mm of coolant. Doesn't appear to be any leaks from hoses I can see, and the passenger side foot well isn't getting wet from coolant so is not indicating heater core is leaking. This leads me back to thinking the head gasket is gone, however no visible white mist from the exhaust?

About a year and a half ago I did the headgasket using a Permaseal MLSR 86.5mm and ARP 2000 head studs, the head was decked and the block was cleaned and checked with a straight edge. Knowing that the block didn't have the right surface finish some Hollomar was used on the head gasket. Everything seemed to be fine until now.

Thermostat is suppose to open at 76.5, however it will hold temp at 80 degrees if cruising. Pull up to lights and it will climb from 80. Bottom radiator hose still cold. Reckon this is a result of bad thermostat or insufficient cooling fan (has been changed to a gktech fan). Might put a new thermostat in for good measure, is a genuine Nissan only purchased a couple months back.

      Hi GTSBoy, Excuse my ignorance but what does a "Bad" Knee point mean ?

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
