Putting in my jjr oil cooler atm and had a accident which resulted in this pictured below to the fitting. Now im wondering since these jjr kits leak anyway without teflon tape will this still work now with the use of teflon tape?

Use a fine file and remove the burr. Do not mark the remaining good part of the taper, because if you're decently lucky, the other fitting will still seal up quite nicely against the remaining bit. I reckon there's plenty of mating surface left. Do not put teflon tape on there. That would be bodgy.

If I got desperate with what you've got there, and wasn't willing to remove it and weld a new one on, I'd screw on a suitable mating fitting with another male on the back side of it, and then seal weld it to the original fitting. That would basically just move it out from where it is.

Yeah I get that part about there still being enough taper left but with these jjr kits and fittings there dodgy and everyone who hasnt used teflon on the thread has had them leak. Im not putting teflon on the taper just on the thread.

Dont ever- ever- ever- ever use thread tape on a jic/dash fittings. It will cause them to leak.

You might be lucky, cut off the protusion and smooth it back flat with fine wet and dry. Do not remove too much, the fitting needs to be flat.

If you have to, run a thin film of loctite on the mating surface.

Are the fittings weld in or screw in? If they are screw in it would be worth getting a replacement. Only on iPhone so can't see the photo great, just looked like a screw in one

Yeah but thats if you apply it to all the threads if you leave 1 or 2 threads it wont be able to break off. Im using some other liquid sealant i got from enzed its rated to work on oils oetrols gases etc. Ive used it on my oil sensors and its worked hopefully will work here aswell.

Maybe pointing out the obvious. But if you know it's going to leak anyway (you said the JJR kits leak in your first post) then why not just buy a new oil cooler?

Oil is the life blood of your engine/turbo, something as simple as this ruining that would make you regret 'bandaid' fixing it now

Yeah theyll leak if used without and sealant but if you use sealant correctly and it doenst leak theres nothing wrong with the kit just abit more labour involved but if you get it all right in the end with no leaks it will do the job. Although if I was going to buy one again I will just fork out double and get a good one for ease of installation but thats not to be said I can't make this one work just got to be careful and make sure its all done right.

ah ok fair enough

I thought they you meant they just leak no matter what

Seen as you have nothing to do, try filing/sanding back the burr so that its nice and flush and make sure its nice and clean.

You want to make sure theres nothing that the female end of the fitting can break off that might go into your oil, if you get what I mean

Nothing to lose so worth a shot

An update on my progress I got it all setup and all and just use the liquid thread sealant on all the threads had no leaks besides for that damaged one so took it off and smeared a light coat of the sealant over the damaged chaffer and let it cure over night and so far running no leaks anywhere. The length of hoses are redicolous im not very happy with how I had to mount them in order to fit them in but what can you do.

FWIW I'm not rough as guts like some, AND I use a JJR kit on my race car, AND I didn't resort to dodgy thread tape usage. I simply assembled it correctly and carefully, and it's fine.

I also found the line length ok, but I did mount my remote filter behind the driver side tower ;)

I did however find a large piece of alloy swarf inside a dash fitting. Not so good.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
