Hello, I am hoping you all could help me with with this

Here is a bit of background on the engine:

I had this engine installed into a 240sx back in 2004, ran good, no big issues. June of 2006 a girl pulls out right infront of me and thats all she wrote for that car. The engine survived, all except for the power steering pump, intercooler and radiator. It has now come time to put the engine in another 240sx.

I was cleaning up the engine today before I put it in the new car and came across this. Seems to be a good amount of oil in the intake. I dont know if this is normal or not. I know a light film is ok but this is a little more than a film, not a giant puddle but a puddle none the less.

I posted this issue on another forum and was given a possibility of three scenarios:

1- Ringlands are bad

2- Turbo seals are allowing oil to bypass and need to be replaced

3- I need an oil catch can

I can crank the engine over just fine using a wrench if that means anything.

I have never ran an oil catch can with this engine (but I will from here on) and was wondering if a long period of use without a catch can could result in this amount of oil?

What is the most reasonable cause for this?

I really would like to know if this is something I need to worry about because at this point it is the only thing stopping me from putting the engine in the car. I am hoping it is not the ringlands or the seals.

Had the same problem. . . oil in the intake turned out to be blown turbo seals and the oil in the breather pipes was blown rings from excesive crank case pressure blowing the dipstick out and blowing oil out the breather pipes

go 2 a decent performace workshop, i recomend electronic automotive in epping, 03 9408 8122, get a leak down test done, they will test 1 cylinder at a time 4 compresson, then position each cylinder at a time 2 TDC and with both valves closed will attach a air hose to the spark plug hole, fire up the compressor, if u can feel air blowin out the oil filler, ur rings are stuffed.....

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
