Tubo Oil Leak?

Just started to drive this r32 gts4 and thought it was using way too much petrol so i pulled the afm off to check and clean it. Found it was very dirty and there was alot of oil inside the air filter and it looks like it has kind of pooled in the coregated sections of the pipe and set like jelly. I know it hasnt been driven for a long time but have no idea how long its been since the filter and afm have been cleaned. Im wondering how much oil blow back is acceptable or weather my oil seals are completely shagged and i need a new turbo. Any comments apreciated.

How likely is it that its sucking up oil from the rocker cover under wot and then getting slamed back into the afm and filter when the throtle closes?

Will clean and check again anyway.

Cheers.

It is very likely, and in my case it was the exact problem.I used to get tons of oil in the intake pipe and the afm and filter were always covered in oiley residue so i installed a catch tank and have never had the same problem, the intake pipe,afm and filter are always 100% clean now!

the catch can is a bandaid fix to the actual problem. if you require a catch can then something is wrong and not operating correctly

Everything is operating fine!nothing is wrong, the car dosent smoke,theres usualy shit all oil in the catch tank (just some watery condensation) and runs perfectly etc etc, the oil being sucked into the intake is from the breather being directly feed into the intake pipe, pretty simple really!

If your turbo seals were toast wouldnt the car smoke very badly??

      Stock rb25det neo questions

      By GTSBoy · Posted

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.

      Car Rotisserie

      By Shoota_77 · Posted

      Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!
