Hi Guys,

My engine saw some serious heat over the weekend (rb25det), turns out my temp gauge doesn't work, it starts out cold and works it's way up to half where it stays. The block got hot enough for oil to burn and the coilpack boots got a bit singed too, bad enough for the engine to seize but some fresh oil and a hill start freed that up. The cause was my headgasket giving out and cyl1 filling up with water. As I'm pulling things apart I'm finding the entire intake is pooled with oil, even the afm has oil splashed all over the inside of it.

I'm tossing up whether to put a new head gasket on this engine, or bin it and chuck in another. I've noticed a lot of oil from where the bellhousing meets the back of the engine, so maybe rear main has also melted out? What other things should I be checking on this engine, rings, bearings, etc? I'll have the block out of the car soon for a better inspection.

Cheers.

    • Middle seat good for a slab of beer or Esky for a road trip. 2x kids, means 1x free seat lol.
    • So we have most the interior back in, and for the first time with one OEM speaker hooked up. The 31 is running, driving and now tunes!!! Hahaha yet another step for the sub that sat 10m under for two weeks!!! unbelievable really 👌 lots of love work and not giving up on her. Seen so many youngsters part way less, and in way better condition. I’m stubborn, thinking another problem is just a hurdle to overcome, One at a time. IMG_9277.mov
    • That is correct. I'm using a modified ABS ring and a ZF speed sensor on my rear diff for speed input. I'm running a Haltech ecu. 
    • Been busy with the newborn. We originally thought we were going to go for a third, but we're good with two lol. He's starting to actually sleep now so I've had some energy to work on the car. It's been parked away in the garage since late November due to winter.  I went ahead and redid all my head oil drains. I originally had my front and rear head drain going into the same pipe but have since split them up. I also added an Ethanol content sensor to get ready to run E85 this summer. Tossed it on my return line. Sensor sits nicely under my intake manifold.    I also have a lot of parts that came in for my rear end. I'll be swapping over to a 3.3 final drive and doing the GK teck anti squat mod. While the rear subframe is off, I'll also change every bushing. We're planning on buying another house soon with the condition that I get at a minimum a 2 door garage, so I'll wait to have more room for this. Now onto the strange things that recently happened... After changing the lower rad hose (It had been sitting in my cabinet for well over a year and was the last hose I had to replace), I let the car idle in the garage to bleed my coolant. After running for a few minutes, it started missing. Got much worst within a minute or two and then stalled and would not restart. My crank sensor decided to crap itself. No damage, no explanation, just died. I went ahead and replaced it with another ZF sensor but the heavier duty stainless model with a shield. Tossed that in and started right up. Has anyone else seen this? I hate when things fail without cause. Luckily this was a blessing in disguise... This lead me to recheck my timing. It seems I may have had a beer or two the last time I had set my TDC angle as I was off exactly 5 degrees... I miscounted a line haha. I was running 5 degrees less then commanded. It's a little embarrassing but helps explain why my dyno operator seemed to think I should be making more then 478rwkws.
