Just jam a bit of coat hanger in the end until you get through the muck and then pump some water through the engine with the hose to flush it out properly before connecting to anything.

Better to get rid of it now. It's not a big issue, i had to do the same when going back to a water cooled turbo.

Tryed unblocking with metal wire only got so fare and wouldn't budge thinking bout on hooking both hoses and gettin the air conpresser onto it blow all the shit out

either that or buy a new hose

go online and buy a datsun L26 or L28 Oil filter stud.Basically you want to find one for the 240z or early 280z.

This will allow you to delete the oem oil cooler.

This is the Oil filter stud

You can install a greddy oil filter relocation kit or any sandwich plate to run your oil cooler.

It's best you shop for a aftermarket oil cooler

There are some cheap ones out there that work fine for the RB20/RB25.

This does requires to move and plug some of the water hoses.Nothing hard.

Super easy to do.

Not sure who is getting confused here but I think op means fitting in inlet manifold is blocked. The water tube Runs between the fuel rail and head but is part of the inlet manifold. The other end comes out behind number 1 injector.

IF he is refering to the tube thats running under the manifold it BOLTS onto the bottom of the inlet. . .he hasnt specified wether its a RB20 or RB25 (have taken it off my RB20 and blocked off feed from head)but they both bolt on, if that one is blocked up i would be suprised as they are of large internal diameter

i removed factory oil cooler off a R33RB25DET and used alloy oil filter block and pressure sender off a R32RB25DE, it bolts straight up. . . this enables me to use factory 32heater hoses/metal outlet-inlets on the 25 going into my 32

U guys are way off topic buddy it's the water line that runs to ur turbo and then runs behind the motor/ ontop of the gearbox bellhouseing into the plenum it's a water return line it's blocked tryed unblocking it today still wouldn't unblock im

Just gonna leave it blocked and run a t piece hose from the coolant lines that run through my throttle body so that way it can still flow back into the coolant system and when I pull the motor out and fix it then

    • 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.
