Water Lines To Turbo And Oil Lines

[demotorsport]

after blowing the seals out of turbo(rear oil seals) I'm worried its a water cooling problem or oil problem.......

it might have been a bad turbo from day 1 but want some advice so i can not worry so much about doing it again

 

ok so my setup is

 

1.t piece bottom radiator hose/and the water line goes to turbo

2.top water neck off the head that goes to top radiator hose has a outlet on back of it that usualy goes to the rear of head/this now goes to turbo

 

is this correct???????????????????

 

I'm aware people usualy use heater hoses and outlet on back of head etc

 

but the way i said will it circulate through turbo properly??????????????

 

would the bottom hose suck water back in from turbo???????????????

and top hose from neck push to turbo????????????

 

the oil goes from side of block to turbo

and returns to sump

I'm confident this is correct but anything I'm missing tell me!!!!!!

but more worried bout the water lines for now

 

if some1 can answer ALL the above questions it will be appreciated

thanks alot guys

I'm assuming this is a standard bearing turbo? is the oil return on the turbo facing downwards? ive heard that if the oil can't drain freely out of the turbo this can lead to blowing oil seals. I THINK.

^^correct, need feed on top, return facing down.

 

Water should flwo fine the way you have it, but the turbo is getting hot water from the motor, instead of cool water from the rad.

 

What motor and trubo are you talking about anyway?

[demotorsport]

4agte/garrett water cooled turbo

 

the turbo is a bottom mount

so YES

oil feed on top

oil return is on bottom

 

and for the water lines

i thought it was pumping hot water

but i find it impossible to feed the turbo cool water from the radiator because...

the bottom hose is the only place where the water is cool from radiator

and thats the hose that will suck water as its infront of water pump that sucks water from radiator and top radiator hose pushes hot water out to radiator......

 

is this true??????????????

and how is it possible to feed turbo cool water from radiator????????????????????

is there another way?????????????????????

I feed my turbo cooler water from my small radiator....the heater box!!

 

Basically the turbo is just plumbed in series with the the heater so the water goes:

Radiator, through motor, in and out of heater box, in and out of turbo and back into the heater return.

 

Is your "garrett water cooled turbo" a GT series? or just like a T25/t28 etc?

As ball bearing turbo can't be fed any oil pressure like a roller/needle bearing turbo, this is what ke25kid was illuding to.

Ball bearing turbos only like about 16psi IIRC max of oil pressure, and need a pressure restrictor in the feed line. If you're pumping heaps more than this into it, it will start leaking oil as you have described!!!

the way you described

it would have to have the turbo feed before the heater box(heater feed hose)

and the turbo return after the heater box which is the (heater return hose)

so the turbo feed would be hot water straight from the engine

any other way wouldnt flow cause if you had plumbed both in heater return they would push against each other and not flow

true or not???????????

 

so you are using hot water out of engine aswell????????????????????

is it ok the way i have done it?????????????????????

would it be flowing????????????????????

 

and by what your saying it sounds impossible to feed turbo cold water

 

and for the oil

I'm pretty sure its just a bush type off a s14

my fitting on the turbo feed inlet looks kinda like a restrictor but not sure its like a 4 to 6 mm hole with a cone shaped edge to seal on the fitting of the oil line fitting

does this sound correct could my oil line be to big for that type of fitting or something???

i ccould take pictures if you like.............

Why so many question marks???????????????????????????????????????????????????????????????????????????????????????????

 

one is plenty!

irokin

your taking the admistrator buisness a bit to far

fair enough if i swear but having a winge about how many question marks is a bit over the top

i do it so my questions stand out from all the rest of the stuff i put in post

 

so you have any idea about the topic?????????????????????????????

or just logged on to have a winge about nothing

if the question marks offend you admistrating is not for you

[irokin]

I'm not sure how question marks can offend me but whatever... Just makes you look like a 15yo OMGWTFFBEBEWQQQ!!!ULEH??!?!!?????? You'll get better answers if you don't look quite so immature.

 

How hots your oil getting? The incoming water being hot wont cause direct issues (many a turbo were soley oil cooled in days gone by....and still today) however it will mean your oil is now carrying the burden of heat and chances are it's been coking which will destroy your oil seals pretty quickly. It could just be that it was an old turbo and almost had it anyway.

so your saying

wrong or old oil?????????

need a oil cooler?????????????

turbo was past use by date???????????//

 

?????????/lol

 

but seriously what are you sugesting

[irokin]

Nah you can go sit out in the cold for now.

 

I haven't spent thousands of hours working on this site (not to mention hundreds of dollars) to have some f@$kwit ignore a simple request.
