Milk In My Oil Cap, None In The Sump.

Hey Guys,

My car has been off the road for a while now while I have been fitting new exhaust etc etc

I fired it up last night and I have white smoke coming out of the exhaust and milky crap under my oil cap.

It isnt coming out straight away but away a tiny bit it starts. It isnt all of the time either, some times it will die down to next to nothing (this is all at idle).

There is no milk in the sump.

Checked the dipstick - no milk.

There is no milkshake in my radiator, only coolant and water.

I have checked the lowest part of my cooler piping, there is no oil (thought it might be the turbo seal).

I have my PCV blocked with my covers vented to a catch can.

My mods list is as follows:

RB25/30

Type A poncams

Wiseco Pistons

Stock Rods

JPC Stainless manifold

PSR 45mm Wastegate

GT35R 0.82

3.5" Turbo back exhaust

Front facing plenum from dahtone racing

Front Mount

Vipec V44 plug in

Techedge 2j1 WO2

Bosch 044 with 3L surge tank

Nismo 740cc Inj

Splitfire Coil Packs

Am using the shittest oil known to man for now, didnt want to put the better oil in until I have sorted the overfueling. 20w - 50 oil.

I have some fully synthetic 10w - 40 oil to go in.

Please help

PLEASE :P

Sitting in the car now with the laptop waiting to go :)

This happened to my last car after a MAJOR thrashing followed by a long time sitting.

Nothing was blown but there was a significant amount of condensation trapped in the motor. I suggest a very good and thorough service before anything else.

Mine was fine after I serviced it and ran it at opp temp and driven for a while.

Yep, coz you've sat it for some time, the engine has had some condensation in it, and where does it condense?? the rocker cover so you'll see it in the cap, drive it for a decent run and it should be gone the next time.

Yeh that is what I am thinking. I pulled the catch can off, and have a small amount of hot water right could just near the 90 degree bend but none in the catch can.

I just checked the oil cap again, there was hardly anything milky compared to last time, I was quite impressed.

I have taken all of the catch can lines and everything off and think I will see how it goes with them off, will help get rid of it a little quicker I guess.

What do call a "good service"?

The car was not trashed in the slightest before it started to sit, it was babied and then just sat.

Did a compression test. Results were between 120 and 130 for all of the cylinders, so no drastic drops. I am not sure how accurate the gauge is, but surely it cant be out 60 psi :wub:

Yeah its just condensation. Drop the oil and change the filter and take for a good run . Some cars during winter that dont get a long enough run can do this as the oil doesnt get hot enough to burn the water/condensation out of the oil.

Cheers thanks guys.

The car was run for over two hours today and there is not a sign of milk under the cap any more :P

Nice new fresh oil and some time without the catch can lines on and there is no milk at all :)

Thanks again.

Similar thing happened to me while my car was off the road for a month.. Except the oil turned milky/caramel. Turns out it was condensation/rust in the motor. I bought 2 sets of oil/filters and changed them after around 5 min of idling, then put some Elf racing oil and its been sweet ever since.

Do a compression/leakdown test to be sure if you like tho.

you should see the inside of a motor that has only done short in town driving......it is full of condensation and sludge in all the corners and nooks and cranny's. Some of the sludge is like black putty. All vehicles need a good long drive for a few hours every few months or so.

Why do you think that semi trailers get big mileage [in millions of km] out of their Mack's/Kenworths etc, because they do haul miles not stop and start stuff

      Also did some work to the shed and a massive clean out of stuff. It's now got a small fab/dirty room and has helped keep shed cleaner. Built some new work benches and re organised things also got a TV out there so good having something playing while working on the cars. Got a pedestal drill and linisher off a mate that need to pick up too.

      R32 GTS (RB20DE) Injectors Replacement

      By Murray_Calavera · Posted

      First thought, have your current injectors flow tested. If they test fine, keep the diagnostics going. It's not the injectors. If the injectors are the issue, find some new or used (cleaned and flow tested) injectors.  While I really love a good excuse to get a modern ECU installed, just needing new injectors probably isn't a good enough reason to do so.

      A bit from column A, B and C. Mainly C   Update time, after deciding it was time to tick off a bucket list goal I finished up full time at MSR and have gotten back behind the wheel and making progress on the S15. Goal has been to drive Bathurst at an event and I have had my entry accepted for Challenge Bathurst in November. Since I don't want to go unprepared I need it running to test and get comfortable.  Been chipping away at it and started by stripping inside, getting it all cleaned and sealing some holes up. With stripping inside I removed the whole wiring loom and found a few surprises.......... its pretty butchered and shit branching and I'm not a fan of the haltech fuse boxes so it's all out and trying to come up with a plan to rewire it all either new fuse/relay box or pdm.  I haven't been happy with how I did the intercooler mounting and been wanting to tuck it up under rad support. O e issue with that is headlights will need a decent trim or get replacement covers. Took the time to mount it with some stand off's and new hardware. Stands are some m8 button bolts, washer, aluminium tube and factory radiator top mount rubbers. It's nice and solid also stiffens rad support which still requires some trimming. Bonus of factory rad mounting is used all factory hoses just need to weld a pressure cap to radiator now. Got sensor block and fuel filter mounted. Plan today is to get vac lines all sorted with push in nylon tube and design oil cooler mounting solution.  Been driving BRZ a heap and went out to Morgan Park for time attack and went pretty well for a wet day. https://youtu.be/gAlQgcQpWj4?si=kojOAOjhhX_X3AXR Getting pretty comfortable in it now and want to do a few more bits to it but restraining myself as don't need 2 race cars at the moment.

      Anyone know this frontpipe?

      By Murray_Calavera · Posted

      @sunsetR33 There is obviously a huge culture gap here. There is nothing in place like this in Australia, where if you fit a Mines branded pipe and later replace it with a Jun branded pipe, both pipes are essentially identical - BAM - huge penalties! Where is the Mines pipe?? You can't have a Jun pipe when you said you had a Mines pipe!  Makes no sense to me. Surely makes no sense to anyone else here either.  I'm sure a lot of us would agree that our registration/engineering system is pretty stupid at times, but it's not that stupid.  *** More serious question here. If you replace a factory rubber hose with a silicone hose, is the car illegally on the road now? Does it become legal if you have certification of what brand the silicone hose is? Then would it become illegal again if you replaced that silicone hose with a difference brand of silicone hose? And then would it become legal again if you had certification of the new brand of silicone hose?  I really want to know that answer to that question.

      Good you making progress with this rig. Aluminium welding is painful to learn, have you got a pedal as I found it so much easier with one. If that's the AMG I think it is, you would working with Benny?
