What Have I Broken?

So I was doing an oil and filter change yesterday, and this thing came out stuck to the magnetic sump plug: :(

What is it, and should I be worried? Can I keep driving the car?

Possibly (part of) an oil squirter?

What is involved in fixing it?

Engine is an RB25DET, NEO block and S1 head

Hey,

That does look like an oil squirter and if so its not good, if you continue to drive since that has come off the piston will start to develop hot spots as the underside of the piston is no longer getting cooled and ping off its head.

The engine needs to be pulled apart to get at it, I am going through the same problem except mine was due to incorrect clearences when it was being re-built http://www.skylinesaustralia.com/forums/Sn...58#entry5396958

LachlanW i reckon it looks like the end of an oxy torch lol. let us know how you go as i want to know how hard it is to change this (IE in car or engine out)

good luck with it i would get squirters to suit your block

i have seen this a couple of times on the forums, is it a common thing? what causes it?

I have no idea how common it is, but it is seems it is either caused by the piston being installed backwards, or the clearance between the piston and the squirter being incorrect, either one causes the piston to hit the squirter and break it.

Yeah, I looked up the part number in fast (NEO ones are different to all other 20/25 :P) and a bit of googling found the following picture:

It's not the best picture, but to me its clearly the same thing.

Unfortunately they are approx 75 bux a pop trade price, and have to come from japan, couldn't give me an ETA :(.

One of my mates has a 25 on a stand atm, so I'm going round this arvo to have a look and try and get an idea of how hard it will be to change in car. If it's too hard, I might just not bother :)

Sprints on Sunday, it won't be fixed by then, so it might blow up and save me having to worry about it ;). A 25 short motor can't be worth too much these days...

banjo bolt is still in, pressure shouldn't have changed. It's broken remember, not come undone. It should just be spraying water oil across the bore, not up to the bottom of the piston

We'll see how we go...

You mean oil... :P

I wouldn't run it but that's me.

I'm pretty sure the oil squirters are to keep the piston temps down, not so much for lubrication, so as long as your combustion temps are ok and your tune is safe, shouldn't have too much of a problem!

Still, Nissan put them in there for a reason...

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
