Hey Guys,

Need some quick help here, should be easily answered by someone. Im just in the process of doing a bit of engine work on the car while its off of the road and i've nearly finished but have a small problem. Im fitting up an oil catch can to the RB25 cam covers because i dont want oil blow by going through the new gear (I know how to hook it up correctly so this isn't the point of this thread before u start flaming me :P)

What i want to know is how everyone has fitted aftermarket fittings into the cam covers??

I rand around to a couple of places and they all told me that they only make fittings with threads, no smooth edges..

The standard fittings have a smooth edge and just slip into the covers, however i dont want to use these standard fittings but something like some speedflow fittings or something. However i think that all of these aftermarket fittings have threads on them, so my main question is, has everyone made threads in their cam covers to fit different fittings for catch cans?? Or do they make fittings with a smooth thread??

Hopefully i have made sense of what im trying to ask.

Thanks guys

Phil

Its easy enough, (im still deciding if i should use fittings in my cam covers, i would like to but they are so exspensive!), if i was going to do mine i would use the following, 2 x -10 male / 1/2npt (so the 1/2npt side would go into the cam cover and the -10 side would be left hanging out of the cam cover, then get 2 x -10 90degree fittings which will obviously screw onto the -10 cam cover fitting.

You would possibly need to take the cam covers off and take them to a engineer or someone similar and get them to thread the holes the same size as your male/male fittings, they may also need to remove the cam cover baffels to thread the holes and make sure no metal fillings/threads get stuck in the baffels.

I would just get the spare hole in the side of the cam cover (the stock pcv valve go in here) blocked off, either get a little bung made up to replace the pcv valve, or get the hole welded up etc etc.

By the way, im not quite sure which sized fittings you would need to go into the cam cover, i was using 1/2npt as an example, but that might possibly fit.

Cheers guys, yeah thats the main idea i was thinking and seems to be what every one on here has done (looked at a lot of photos of engine bays and yeah its what most people have done).

Only thing its a lot of mucking around just to hook up an oil catch can...hmmmmm still a bit undecided but i might have to get them threaded.

Much appreciated guys.

Braided lines are not just for use with high pressure applications. They provide a protective shield for the lines themselves, prevent bulging, looks good, extends the lifetime of the hose and will not allow the hose to crack and leak like some normal hoses do. This is even more important when your dealing with your engines life blood in a high performance car. Hence the reason, I'm going to replace the majority of my hoses with braided equivalents.

How do the std fittings come off?

I tried pulling them off but all they did was spin...

Mayb I hadnt eaten my weetbix...

Since they are smooth and dont have an actual thread, once they start spinning just pull them upwards and should slip straight out :)

      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!

      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.
