High pressure oil feed line diameter - 306Puggy - 10-02-2014
Since no one feels like replying to my existing thread on the subject, I have started a new thread. I have thought of everything except the friggin' oil line diameter. That was the first question the Pirtek man asked. So anyone know what the diameter needs to be for the oil feed line? For some reason I am thinking 8 mil but maybe getting muddled up with the fuel line. Also what length should it be? Some say 12 inches, some say 1.5 feet which is 15 inches.
Thanks.

We'll guy who made mine up said it's quarter of an inch something like that and no idea on length get tape measure out and lay under car
RE: High pressure oil feed line diameter - Niall - 10-02-2014
Still not fitted that turbo yet? pfft.
RE: High pressure oil feed line diameter - 306Puggy - 10-02-2014
I do not rush my projects Niall
Better to do it properly once so it goes on and stays on than do it in properly and have to take it off again. Once I get an SD card reader for my new computer I will put a new project thread up to update you on the progress and the issues which have slown it down. Until then, shut it :p(10-02-2014, 05:06 PM)Chris_90 Wrote: We'll guy who made mine up said it's quarter of an inch something like that and no idea on length get tape measure out and lay under car
Bare in mind I need accurate info, no point getting it made up and it's too big leading to low pressure and a blown turbo <_< Also measuring the standard line is not possible because it is a solid steel line with bends and there is no way to get a tape measure by it. Not being pedantic, just in case a certain person says "Oh, you've had loads of answers and ignored all of them". You know who I am talking about
Edit: Just in case anyone gets this thread in the "related threads" section:

It only tells me the outer diameter, not the inner one. I thought I was close to finding a solution but turns out to be a red herring.
RE: High pressure oil feed line diameter - Chris_90 - 10-02-2014
We'll I measured mine off the solid pipe with out issue, the hydraulic place said that's the right size I need for turbo. Just go talk to your local company and they will advice on what size pipe is needed, as for length I will measure mine when I get chance, I'm guessing your coming off the block? Or you coming of the standard line?
That's what mine looks like gt20 to btw

RE: High pressure oil feed line diameter - Piggy - 10-02-2014
isnt Jenks still making these??
8mm is pretty thick to be honest for a high pressure feed. I would think a 6mm inner would be plenty

As I said quarter of an inch!

Heh, good find bud. I am a bit torn between getting a totally flexible one made up with fittings or getting a very short piece of flexi attached to the end of a spare standard line. Trying to weigh up the pros and cons of both at the moment.

Probably coming off the line as it saves having one fitting made. Don't worry about measuring anything if I am gonna get the line adapted. Seems the best thing. Just need to find someone selling one!

Personally get all flexy, the one that goes in the end of the standard line is a bit of a pain.

Do this was only £20 for mine had to have an adaptor for the block tho but was all in on price.

A dummy would just pour oil over his engine...what I did takes time, effort and money!!
RE: High pressure oil feed line diameter - padge - 10-02-2014
just get half inch in diameter.

12mm? Think that's abit excessive
RE: High pressure oil feed line diameter - Piggy - 10-02-2014
Mega excessive
RE: High pressure oil feed line diameter - padge - 10-02-2014
think everyone round here runs half inch, on td04s, no issues
RE: High pressure oil feed line diameter - Dave - 11-02-2014
You can make it out of whatever size/diameter you want. The pressure is still going to be coming from the block, the only detailed part you need to get right is the restrictor going into the blower to ensure no popping of seal, and maintaining enough oil pressure to the rest of the block. They're normally about 2mm but the rest of the line can just be made up it wont affect anything as long as restrictor is correct.

I mean braided oil hose. The type that people get oil hoses made out of, you know?
Apparently a popular solution is to get a short piece of braided oil hose fitted to the standard line with a connector on the end for the non standard turbo but from what Tom says a flexi is easier.(10-02-2014, 09:44 PM)Tom Wrote: Personally get all flexy, the one that goes in the end of the standard line is a bit of a pain.
Hmm, okay then. That does mean there is still going to be a question mark over length. I will go for 12 inches as suggested unless anyone can forsee any problems.

I haven't heard any mention of restrictors before, but the oil inlet on the CHRA is already about 2mm, I guess that means the restrictor is built in. I see what you mean, as long as the restrictor is restricting the oil flow, the correct pressure will be maintained. But I will go with a 1/4 inch hose anyway as that appears to be what everyone uses.

Im just mentioning this because on the lorry blower I have it uses an oil feed pipe of 10mm to the blower, so oil pressure would be non existent if I didn't make a restrictor for it.
RE: High pressure oil feed line diameter - 306Puggy - 12-02-2014
Well Dave as far as I can tell the restrictor is already built into the turbo CHRA, when I get my SD card reader for my new computer I will upload a picture to show you what I mean.
Edit: Right, interesting development. Apparently Pirtek outsource to another company so the Pirtek guy have me their phone number to speak to that other company directly. Said other company is near Silverstone so not exactly local and therefore I can't bring the turbo to them to show them which fitting goes into the end of it. So I will have to guess that part. Why is everything so damn complicated
Edit 3:
I can confirm, that on my GT2052 at least, the oil inlet to the turbo CHRA is the same size as the Lucas pump fuel inlet fitting (the bit that the banjo bolt screws into), which I believe is M14x1.5 but can anybody confirm that? Thanks.
RE: High pressure oil feed line diameter - 306Puggy - 13-02-2014
Right, got a picture of what I think the "restrictor" is, seems to be just part of the oil inlet TBH:

As said for the oil feed a lucas fuel pump fuel inlet fitting threads in there perfectly so I am guessing it is M14x1.5 but just want to be sure.
RE: High pressure oil feed line diameter - Chris_90 - 13-02-2014
its m12 x 1.5 and the block thread is m16 x 1.5
