ok i bought a r32 cheap, obiously there was a reason why an this im guessing is it,

its a r32 with high mount turbo bla bla bla

what seems to be happening is the oil is getting into the coolant somewhere, the actual engine oil doesnt get mixed it stays clear but the coolant is milky as fark, the gauge doesnt work in the car but it is overheating an emptying the radiator fast,

soo im guessing headgasket??? a oil chamber is leaking into coolant chamber?? but why doesnt the oil galerys get coolant in them ???

the guy i bought it off had engine oil in a coolant container ? is it possible he topped up radiator with the engine oil an thats why it keeps boiling quick ??

the car has no boost at all im getin a flat 0 on the gauge with minimal power

help someone out there!!!!!!!!

maybe get a compression check, if its the head gasket thats gone as soon as it will try to boost it will just be leaking the boost out of the gasket, hence no boost, and you would have to be really stupid to put oil in the radiator,

ther may not be coolant in the oil because its more combustion gases that are getting into the coolant,

when ur car has been sitting over night does it turn over slowly for the first crank, if it does it could be coolant leaking back into the cylinder, but twhen its running the combustion is pushes into the coolant.

well i fully flushed out all the oil in the coolant, i rang the previous owner n he did say he put the "coolant" (actually oil) into the overflow bottle, i now have the other problems to look at which are

no boost max im getting on the gauge is 0 lol

smoke coming out of the catch can filter but its not even connected right ( is a line ment to go to sump? i only got to coming off top cover)

small amount of white smoke coming from exhaust on start up an rough idle on start up??

we can rule out the head,

i drove the car for over 1hr today

coolant remained same level no mixture of oil n water in ether motor or ratiator

i figured out why its not coming on boost lol im not reving it high enough!! DUHH lol over 5000rpm it starts up (i dont thrash my cars much)

only problem remaining is white smoke on start up??

there should be boost well before 5 grand unless u have a mammoth turbo

a standard 32 should start spooling at probs about 2-2.5 grand under load and have full boost by 3.5-4

He did say it had a high mount.. and full boost on a stock RB20 with stock turbo by 3500rpm?? That's when the 25 turbo on my RB20 was making 12psi.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
