it means your turbo is blowing some oil through the inlet tracts ...

some1 correct me if i'm wrong here, but tis possible that the oil seals on the compressor side of the tubby are leaking oil and its blowing it through your intercooler, when your bov releases the pressure, that small amount of oil in the inlet tract gets vented to atmosphere .. onbiously not much oil, but over time it will build up ...

just me 2c

sounds right.... as over a week of driving there is only a small amount of oil around the place... what am i looking at for a repair cost if this is the issue?

went for around a 40 minute drive, warry of the police on double demerit hunt... and looked at the bov afterwards... and there isn't any oil on it... so i am assuming that is is only a minor problem for now...

planning on getting a leak down test and compression test done? how much would this roughly set me back? and can any workshop do it?

if tests show fine i guess i will install a catch can...

if tests show some kind of fault.. i will go from there?

how much would UAS charge for a compression n leak test? as i work across the road... so can dro pthe car of in the morning, and pick up after work :cheers:

Also a catch can wil cost around the $100 mark from my knowledge? any suggestions on brands/types/ where to go for installation around hills area?

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
