4agte turbo oil drain

[trd3sg]

thanks for the advice - my only concern with doing this was starving the head of my gen 3 3sge (N.A oem) of oil.

Thanks fellas and sorry for the partial hijack

DOHC 20 - nice work

if you dont mind me asking, is your motor running in FWD format?

If so, where did you take you're oil feed for the turbo from?

Thanks

nah mine is RWD format, i got my oil feed from the oil pressure switch by using a T piece setup pretty much the same way ChuckLandwehr said.

cheers for the replys +rep

Yep its for an AW11.

The manifold is one of the cast ones off ebay, my friend got it cheap off another freind so we thought we would give it a go.

I think the only way to run this manifold would be with a scavenge pump or one way check valve.

This manifold is going in the bin. LOL

[oldcorollas]

check valve = no good.
PS scavenge pump could work easily

[Jayem]

single small scavenge pump to pull oil out of the turbo? ie, PS pump or similar?

Alternator from diesel engined toyota, nissan, mitsu etc does have vacuum pump. That would be compact...

cartledge : can you post a pic of the manifold from side on ?


I think there will be just toooooo much stuffing around to get the oil scavenge setup to work right.
You will certainly have a prob with the manifold sitting the turbo that low too.

I be looking to modify the manifold by cuting the flange (turbo) off and taking a inch or so out and re welding it on.

Other than that a different manifold design.

I know this isnt what you want to hear but in the long run it will be ALOT easier !

problem is when you cut the stock manifold high enough to mount the turbo in a better position the 2 secondry's a kinda split making it harder to simply attatch a flange too. i tried it after my 1st stock manifold - turbo manifold 4agte conversion back in early 02.
(i do have a bodgy diagram floating around somewhere).

Mounting turbo too high also gives clearance issues with shifter cables and clutch slave cylinder plumbing. Atleast it did for me .

Thats why i wanted the side on pic - to see what we are working with.

PLONKA : I dont think in this case we will have a prob with the turbo being to high. ..... but good point to consider.

[feral4mr2]

as i might of said in this thread (sure i have in plenty others on this forum and others over the years) that on the aw11 the turbo flange is best positioned close to inline with the top of the oil filter boss on the block. this saves headaches on oil return issuse and shifter/engine mount issues.

If you want more reading on this topic, I started one a while back on oil supply and drain. I had a lot to learn.

You can see there what I did about the oil supply to the turbo. The oil drain I used hasn't caused me any issues and it's been like that for over a year now.

[Duk]

Does anybody want to have a crack at how much oil is actually in the sump when the engine is running
Obviously a lot of it will be doing the rounds through the oil passage's and hanging around the camshafts and cam followers, so how much is still in the sump?
A rough measurement by sticking 3.2ltrs of water in a sump, had the full line about 35mm below the sump bolt flange, but in reality you could have the oil drain lower than this because the running engine oil level will be much lower..... but how much lower?

Plonka, an engine left sitting overnight, showing full on the dipstick, when just shut down, the oil level is about 1/2 a littre off full. So my theory, would be about 1/2 a litre is constantly in the engine galleries/filter etc, whilst running.

This is why you never fill a hot engine to the full mark on the dipstick.

cheers Chuck.

Sorry for the delay,

side on



The manifold is cast so there is no cutting and rewelding of this one, we a are looking into alternatives at teh moment

["Z" UTE]

That manifold positions the turbo quite to the gearbox end of the engine, well clear of where a RWD engine mount would interfere, so maybe it was meant for a RWD application. Just spin the turbo through 180deg, and you should get the picture.

cheers Chuck.
