Turbo is a garrett Gt3540 i took intake piping off and noticed there is oil infront of the intake impellor and also in the oulet pipe to intercooler what does this mean??? Perhaps this has got to my AFM hence why i have had idle problems, i have noticed when i turn the car off i hear the turbo wind down for about 30 seconds after. Surely the oil seals cant be leaking its a brand new turbo!

Do you have your breather hose going back into your intake pipe like std setup does? If so then the case is simply any blowbly/bad breath is going through your intake system and into your pipes. If you dont, then yeh....magic perhaps?

If drain is blocked it will push oil through the front seal, also if you have to much crankcase pressure.

Yes thats what im thinking "Crank case pressure", because at one stage for one start i did block my oil breather up when i was connecting up the catch can, maybe this is the excess oil from then, i noticed it started to blow smoke then and once i fixed it up stopped, lucky i didnt blow the oil seals in the motor... this was all caused because i hooked my catch can up the same way as in an r33 and my car being an r32 i didnt realise i had blocked the oil breather... What the best way to test the oil drain and see if it is draining well enough???

pic of the engine bay please :spank:

The oil on AFM will be causing idle issues, without a doubt.

Simple degreaser will fix that one.

If the Rocker Cover pipe is still connected to the turbo intake before the AFM, thats the most likely cause

The oil return probably wont cause oil in the compressor/intake side of the turbo... its rare.

Did you check the flow before installing the turbo?

Yes my car was hunting up on idle from 300-800, and i can see the oil stain on the pod filter...

Ok ill get some pics as soon as i have a chance, there are no pipes connected to the intake before the turbo at all. What do you mean by checking the flow???

lol actually i was in a tired silly mood, i was gonna say 'magic' was the only thing left. But yes excessive crankcase pressure, but wouldnt the dipstick have shot through the bonnet? Perhaps not to that extent.

Remove it and inspect, look for a blockage of somesort. I would think it would be pretty hard to block up a 3/4" hose, unless its further up in the arse end of the turbo itself before the hose.

Your catch can system is breathing right? It hasnt recently sprayed out excess oil over your intake system maybe? We had a similiar problem with the race car, pcv was stuck open half way and boost was leaking out into the rocker covers and forcing oil into the catch can and then spraying it out the breather and straight onto the filter and through the afm and into the turbo. Safe to say no more pcv into intake manifold anymore hehe :spank:

LOL yes i did hook it up wrong and i didnt have a dipstick in but it did blow almost 1Litre of oil out of the dipstick hole and the oil in the dipstick and the rocket cover went a milky colour due to the presurising then my car started to blow tonnes of blue smoke when reving i thought it was a blown headgasket then i realised i had completely blocked the breather on the plenum.... OOPS :spank: I think this is the excess oil that would have been blown through then as there was oil only around where the hose clamp fittings where hence maybe it had been there a while. I have noticed a wind down noise from the turbo when i turn her off is this normal?? At the moment i have connected my catch can as follows, i have left hose from plenum to both cam covers then where it used to go back into the intake piping i have hosed it into one side of the catch can and the other side of the catch can is venting to the atmopshere...

i have the same thing on my HKS 3040 . small puddle on the silicon joiner on the Compressor inlet ..

same as you i dont have the catch can return going into the pipe either.

i bought mine 2nd hand, but if you bought it new from a garrett reseller try asking them or garrett directly

Ok well at least im not alone :spank: , ill be calling ATS tomorrow, must be a seal problem by the looks of things if you have the same problem...

      🚨 Need Advice! Overcharged for Engineering Report 🚨

      By GTSBoy · Posted

      This is actually 2 whole different trains of thought that need to be addressed separately. No, as Matt says above, "Engineer" is not a directly protected title. A lot of guys who just do mechanical design via CAD, with or without even some sort of associate diploma in engineering, often have the job title of "Design Engineer". A train driver can probably still describe themselves as an engineer. But, to usefully get employment with anyone as a proper engineer, you're going to have to have at least the necessary and relevant degree qualification. You're not going to get a job as an electrical engineer if you have a chem eng degree, unless you can demonstrate x number of years of working in that capacity, sufficient knowledge, etc. Having the degree is at least in indication that you've seen the relevant text books, even if you haven't read them (like pretty much the last 10 years of graduates!). To be a self employed engineer.....you could get away with quite a lot pretending that you're suitably qualified, without actually being a proper engineer. But, you will find yourself unable to work for a large section of the client space because a lot demand CVs and capability statements when considering contracting for any engineering work these days. Insurances too. If you're not a proper engineer, it will be much harder to obtain proper PI insurance. Insurance companies have gotten hip to that. The "Professional Engineer" thing is a thing in Australia. If you have the right qualifications and experience you can apply to the relevant engineering top level body (mostly Engineers Australia, the less said about whom, the better), to be assessed and approved as a Chartered Professional Engineer, CPE. There are high bars to get over and a requirement for CPD to maintain it. The RPEQ thing is similar-ish, in that you have to demonstrate and maintain, but the bars are a little lower. It is required to be RPEQ in order to sign off as an engineer on any engineering design in Queensland. The other states haven't fully followed suit yet. There's "engineering" and there's "engineering". Being an engineer that signs off on timber (or even steel) frames for housing projects, council creek crossing bridges, etc, is a flavour of civil engineering that barely warrants the name, description and degree. That would be soul crushing work anyway. Being an automotive engineer working in the space where you have to sign off on modifications to cars and trucks would also be similarly soul crushing. At least partly because of the level of clientelle, their expecations, depths of bank balance, etc. And that brings us to your second question. No, we do not have professional engineers "do vehicle inspections". Well, not the regular roadworthies, etc etc. That's done by mechanics. There might be some vehicle standards engineers at the various state govco inspection stations where cars go to get defects cleared and so on, but that's because they (the cars) are there specifically for defect inspection and clearance and so the stakes are a little higher than on an annual lights and brakes working check. But, if you modify a vehicle in Australia, you have to get it engineered. A suitably qualified (and effectively licensed, which I will get back to) automotive engineer will have to go over the application, advise on what would be required to make the mods legal, supervise some parts of the work, inspect and test the results, and sign off. The "licensed" aspect comes from there being a list of approved engineers to do these things in each state. They have to jump through hoops set up by the govco vehicle standards divisions that mean only the suitably qualified can offer to and approve such mods.

      Meh, it's only got to last another 10 years or so until you'll be forbidden to drive it. Keep it dry and forget about it.

      The title of Engineer is not protected. However different states have different rules about what an Engineer requires to operate. Engineering for a motor vehicle modification is very different to engineering for a bridge, electronics, etc, including what that engineer needs as certifications.   In Canberra, "Engineer" is the loosest category with basically nothing stopping you calling yourself and engineer and designing a bridge or building. From what I've reviewed, QLD has the strictest requirements through RPEIQ.
