I'm from the UK and I was surprised at the rust! Anyone might think that they used low quality steel... Putting the engine back in is like painting, everyone wants to get to throwing the top coat down, but it's the boring prep that makes it a good job. It's not a forever engine, but you've spent good money and time to get this far, might as well do a full job. I'd wait and not rush to get it back in, as disappointed as I'd be. Because I know how mad at myself I'd be if it breaks again. Not worth the self-aggro, mate :)

Ah, there. Oil out of the exhaust ports from a cracked ring land is pretty common. Oil would have gone into the 4th cylinder and out of the exhaust ports into the turbo, I'd say.

[@ZeroTo60Tube]

It definitely should have. What is strange when it first happened there was no smoke. Hmmmm we'll see. pretty sure im just going to bolt them on to the e90 motor and get it back on the road.

[@typedrew]

i dont think i realized you hadnt plugged your head ports. You need to do that while its apart. Especially with your port injection firing 'up' and into them. It will dillute your oil quickly and cause lots of excessive pressure espeically with all the boost you had wound into it and could be a major reason you had an issue with the old motor. Plug those head ports while its apart, and a proper high/low catch can system.

[@ZeroTo60Tube]

BRO!!! what the.... i honest to god never thought about the fuel getting up in there. Shit. I've been putting off plugging them, because you know... it costs money. What brand catch can would you run?

Oil in the turbo is from cylinder 4, you most likely cracked the piston and ring which will allow oil to go up past the rings into the cylinder and into the turbo

[@sachak]

So I fitted port meth injection recently. I have been running charge pipe methanol for over a year, I had my valves walnut blasted back in 2017, and they were still pretty clean I have done around 45 000km since then. I have no oil catch can. I saw the valves a few weeks back when I fitted my port methanol injection. I would look into methanol injection if I were you as it really does keep the valves clean. I am guessing that with my new port methanol injection my valves will probably stay clean for the foreseeable future. Port fuel injection is nice but Methanol is very corrosive so it keeps valves squeaky clean. My throttle body looked new inside! I remember the first time I took my throttle body off before methanol injection it took me a good hour and a half to clean with carb and brake cleaner!

[@ZeroTo60Tube]

Thats interesting. I have been investigating meth injection lately. Mainly for cooling. But this is another plus i guess.

Id get the new downpipe connection seals before throwing them back on replacing them would be a pain and they already seem a little bad. Dropping that subframe with the motor in the car is a pain in the ass!

Run a dual oil catch can, you have one on the high side you need one on the low side with an external PCV to prevent oil issue

[@sulimed]

I hope you're thorough with your assessment of the 17t turbos. My stockers just shit the bed and I was planning on getting a set because I saw the success you guys were having with them. But you've only had them on for a little while so if the turbo seals are already going I think I'll just get a stock rebuild... I appreciate the content you guys put out

[@milehighboost5521]

Doesnt appear his turbos are bad but rebuilding the stock turbos isnt a bad idea as an alternative. I replaced the wastegates of course and rebuild the internals of the turbos with turbo lab of america parts and now my turbos have no problem quickly spooling up to 21 psi on a mhd backend flash. Im sure i can push them to 24 psi without issue given what others have experienced.

[@ZeroTo60Tube]

I am fairly confident this oil has come from the engine, you can see its built up on the wastegate flapper, the oil can not get to the wastegate flapper from the turbo oil seal. So it's probably fine. The strange thing to me right now is how rusty the housing is.

[@schmick63]

A catch can on the high side which you have will catch next to no oil. You need to externalize the PCV and run a low side can as well. It captures heaps of oil.

[@ZeroTo60Tube]

Any thoughts on a particular setup to go with?

[@FriendlyIntentions]

The more oil buildup on the last 3 cylinders is due to the path of least ristance from intake manifold going to the back 3 ports. The oil from the turbo is because the air that has all the oil from the PCV vent gets thrown at the rear turbo due to the reason above. Go look at the intake mani and the last 3 ports.

[@donaldpollock5118]

The turbo may not be shot. If oil cannot flow properly back to sump it will back up and overwhelm the seals and thus oil through the turbo. Make sure oil drains enough

[@holeshot895]

Good progress, before you assemble the new motor I would figure out the failure point of the old motor and the source of your oil leak. Oil leak is most likely associated with your engine failure, you should be able to see something in the exhaust chamber. Good luck.

[@ZeroTo60Tube]

Absolutely. Well the plan is to see what happens to the e90 motor when its in stock form as well. Just in case my e92 failure was a anomaly. When the e92 motor gets built i really want that one to last a long time.

[@KnightMetro1]

Very surprising on that buildup on the valves even with port injection. Maybe move to a high side and low side catch can. I'm going full external PCV and plugged head ports just so I never have to find a surprise like that again. Fingers crossed on the turbo's being fine. I'd love to see more success stories on these budget pairs.

[@flinchy952]

A lot of people don't realise that since you're only flowing through the port injectors at WOT, and you're cruising most of the time, they don't really do much to prevent carbon buildup. Gotta plug the head ports and go external which is ugly and a PITA

does the car throw any codes when running a catch can and is there much benefit running the different injection setup just curious and what type of scan tool are you using. get your self a cheap boroscope then you can look in all the hard to get places with ease . look inside the exhaust ports with a torch and see if any are wet with oil if so clean the turbo and run it. a little trick for cheap hp get a soda stream bottle and a solinoid run a line to the front of the intercooler and put 4 spray nozzles in front of it and spray the pressurized co2 on to the intercooler use small tricklon hose and nozzles hook up the solinoid through a relay on the boost controller when it comes on boost it sprays ice cold co2 on the intercooler spray as a gas or a liquid it will still sublime to a gas at 1 atmosphere co2 gas deposits to a solid below temperatures of -78.5 degrees and sublimes to a gas above -78.5 degrees in its solid state it is commonly called dry ice so as a gas spraying on to your intercooler should be around -78,5 degrees cooler the air means more hp correct? keep up the great content cheers glenn

Hey great video again, The only other cause for the n54 engine to leak out of the exhaust is if the valve cover gasket is gone(besides obviously having good compression). which I doubt because your spark plugs and injectors would be covered in oil. Your turbo seals have failed? Don’t waste your time please the turbo needs to be re-built. If i was you i would just take the cost on both seal kits and then it peace of mind that there both have been replaced and don’t forget these are Chinese turbos im not surprised?

@@ZeroTo60Tube just thinking about it.. Pretty much worst case scenario for the corrosion is after a pull and then let you off the throttle. The manifold will be red hot and the motor will then be pumping in oxygen rich exhaust into it. It's eating it alive lol.

$6000?

[@ZeroTo60Tube]

No no no..... way cheaper than that!

[@elivibes5576]

$1500?

[@ZeroTo60Tube]

Nope. But now i am not saying higher or lower.... but i will say $1500 is closer than $6000

208000klms. Which is high for one in Australia.

My guess on how much u paid for the car is $1,200 USD.. not sure what that translates to in AUD.. I believe its about 1,720 AUD.. let me know how close I was lol

[@ZeroTo60Tube]

Pretty good guess!

Can’t believe how fast the carbon builds up, a believe a meth injection is a no brainer at this point. I’m guessing $4k Aussie for the new car?

[@ZeroTo60Tube]

Well my PI hasn't done much to clean the valves..... but i guess i'm not on the gas that often and when i am you're talking 3 or 4 seconds or you are going to fast anyway. $4000....... jesus... not that much.
