oil feed problem on a 4agze turboed

[James Sen]

im about to turbo a 4agze and im almost complete, but before i do i just wanted to know if theres anyone thats done one and had a oil supply problem, because i've got a friend thats damaged 2 4agze engines after hes turboed it because the oil wasnt supplied around the engine properly.

[evil_si]

never had an issue.
fit a 't' piece into were the oil pressure sensor goes and run your turbo oil feed from here

[SpeedRacer]

dont use anything except steel braided teflon lines with the screw ends, not push lock hose crap.
you'll cry at the price but its better than having oil piss out all over your engine and maube casue a fire

Never had an issue with the pushlock lock, just get the right lines and it shouldn't be a issue. And as said above, just use a T into the oil pressure sendor/switch. Bear in mind that some turbos require a restricter in the oil feed line

[l1ttle_d3vil]

is it possible to use the standard outlet by the oil pump on 4agzes as a feed? or is that too small? and does the same apply to the return line thats already fitted to 4agze sumps? I think the lines were for p/s originally, are they too small for turbo lines?

Return is far too small. Its for the oil cooler in some models.

Don't know what outlet you mean though...do you mean the bung in the gallery for cleaning etc?

EDIT:

Or do you mean the one behide the oil filter that used to go to the oil cooler? If so, you can't use that, its like a umm, overflow type thingee, under some circustanices, oil is not always pumped through there under pressure. Just t into oil feed line, and build a return.



And as for push lock...

I wouldnt touch it.

I caught mine, maybe 30mins driving time before it gave way and spewed hot oil on hot manifold. I touched it and it broke apart :S.

One month later, i check the new line, and it was cracking again.

Speedracer above did the same thing, but he didnt catch his in time....


USE STEEL/TEFLON LINE!!!!

I think you may be looking at what is actually the bung that holds the oil pressure relief valve in,

which there is no way you can use it as it's not an oil feed.

the only two places to get oil,

Out of the hole where the sender screwed in,

or out of a fitting in between the oil filter and the block if you fit an aftermarket adapter or cooler fittings.

yeah i was gona t piece it from the oil pressure switch,i think the problem with my friends engine was that they didnt t piece it and removed the oil pressure switch so they had no warning of low oil pressure. well ill see how i get along and thanks for the help

What the hell...

If that light EVER comes on when driving, you've got a pretty good chance for $&#$% something, so weather or not the light is there, things are going to be bad.


Answer = Don't run out of oil...

Yeah normally the light sw pressure is so low that,
it doesn;t tell you your pressure is low,
it tells you your engine is fkd.

Most are about 6 or 8psi.

I run 25psi + in race cars

The oil light should be named the your fuked light

I took my oil feed from an oil filter relocator. Relocator has place for four fittings. Two are used for the filter (oil from block, oil back to block), I blanked one and used the other for the turbo feed. I used speedflow fittings with ss braided teflon tube and a 40 thou restrictor.

Ive never used push lock but I would only use screw lock seals on pressure side (or crimp if you can get a hold of the equipment).

[Barks]

I'd go for a remote mounted oil filter and take the feed off that as well (I would wouldn't I, seeing as I bought Caveman's turbo setup)

Not only because you don't have to worry about messing about with T-pieces, but relocating the oil filter makes things SOOOOOOOO much easier, especially if you've got turbos and manifolds and dump pipes and wastegates in the way.

I wouldn't even think about push fittings. IMHO those things are designed for pneumatic rams and they should stay that way. Steel/alloy screw fittings all the way.

I think there was a guy selling remote mount kits on tardme a little while back, they were going for about $350-$380 with an oil cooler. Dunno about the quality though.

[Barks]

Just having a think about things, Isn't the hole where the oil pressure sender screws in before the oil filter? That would mean if you use that you're sending basically unfiltered oil straight to the turbo

Remote mount filter looks better and better every time

someone wanna show me a photo of one of these sensors on the block? they are just left of the oil filter with a single wire coming off them?

cheers in advance

[slighty_sykotic]

Yup thats the one. Round thing.


And yes, your getting unfiltered oil, but remember, it went through the filter before it came to that point, it was just a while ago.

If you change your oil more than once a decade, it should be fine.

I know lots of people that havn't killed turbos due to that.

here ya go...........

[Psycho_Dad]

neato, so its the big hex shaped one?

[slighty_sykotic]

In that one yup,

But many of the early 4ages its round. like:....

That is a crap picture to post really as hardly any car actually had the part labelled in there as the oil cooler feed.

[slighty_sykotic]

I know, I wanted to show the round oil sender, as most of the 4age one were.
