What is this piece?

[pszemia]

Hi there.. i am looking to replace this oil line, because i found that when accelerating, there is oil leaking from this line, and i don't know the piece number to replace it, or if i can use another OEM to replace it.

It's the metal (gold color) that come from cyl 1 at the block (i think).

Here is a pic of it (circled in red):


thanksss

It appears the PO installed oil-fed chain tensioners. If so, that's the thin oil feed line leading to the tensioner. There's a similar oil line on the right side of the engine.

A later upgrade added some brackets to reduce the line from vibrating and failing. After replacing the leaking line, install the support brackets.

Pelican has these parts.

thanks sherwood, can you help me with the pieces i am making a big shop from pelican, but because my technical english is not so good, i don't know well the pieces name..

thanks!!

it's called a Tensioner Oil Line, found on a 1984 carrera to 1989 model year. Left or right, in this case, it is a left line.

[pszemia]

but mine is a 1973 MFI, that tensioner oil line fit's in the same place, and it's the upgrade??

do i need another piece for it??

thanks!

Yes, you have the upgraded, oil-fed Carrera-style tensioners. It appears from your picture that whoever did the work did not use the necessary support brackets and clamps for those auxiliary oil lines. When you order your oil line, include:
1x left bracket
1x right bracket
2x clamps
2x clamp screws (bolts)

When the supports are not used the auxiliary lines can crack, which must be what happened to you.

This is what it looks like on an 1987 3.2 liter engine. Not sure this will help. The leak is from the rubber transition piece in the middle of the picture, not the smaller chain tensioner lube line directly to the left. Look closely at this smaller chain tensioner lube line and you will see how it is held in place with bracket and rubber collar.

[pszemia]

1x left bracket
1x right bracket
2x clamps
2x clamp screws (bolts)

are this the piece numbers? (i don't wanna mess old with new ones):
1x left bracket --> 930-107-341-00-M260
1x right bracket --> 930-107-342-01-M260
2x clamps --> 999-511-174-02-M260
2x clamp screws (bolts) --> 900-119-059-02-OEM

and this are the lines??
left line (the one i have leaking) --> 930-107-347-02-M20
right line --> 930-107-348-09-M20

should i also buy this ones and change the ones i have? (i mean essential ones, because of money.. :S):
left pressure-fed cam --> 930-107-347-10-M20
right pressure-fed cam --> 930-107-348-11-M20


checking with sig_a picture, the new oil line, is different from one i have, and i don't think if it will fit or if my original line has been changed by previous owner, and i don't have the right one.

mine has a curve and goes under pointing to the right, and this one, goes across to the left, in different position...

The main line, pictured with the wrench, is completely disconnected at the other end. I was in the process of removing and replacing it. The new line was reconnected where the wrench is pictured, and at the other end where the gold colored female threaded fitting is located. Look closely at the upper left hand corner of the photo. The fitting point I'm referencing is adjacent to the lower corner of the valve cover nut. You can see easily see the fitting's open end and female threads against oily black background.

The smaller line you are thinking about buying the bracket for connects to the "inline tee" just to the left of the leaking rubber transition on the main line.

Not sure you can modify your 2.4 liter 1973 911T with parts designed to fit 1984 - 1989 Carrera. Perhaps someone here can chime in and give you better info. But if you can make the complete modification, you will need the following parts to add to your list:

900 123 115 30 OEM, N 021 073 1 OEM, 900 104 003 02 M20, N 020 825 1 M20, 900 123 005 00 M131, 999 134 018 02 OEM

Buenos Aries must have a Porsche dealership to help with correct part selection.

Good Luck.

pszemia already has the pressure-fed tensioners installed. I believe the current issues involve the correct part number for the left side oil supply line and the recommended support brackets.

These parts are interchangeable all the way back to when they had a different chain box cover design (1966?).

The replacement parts are on Pelican's parts catalog page:

http://www.pelicanparts.com/catalog/shopcart/911E/POR_911E_ENGoil_pg4.htm#item13

Andrew M had this kit for sale awhile back:
FS: Chain Tensioner Kit



Match the pieces with the part numbers on Pelican's catalog page. Notice the cushioned, metal support brackets installed on each tensioner supply tube.

It's also recommended to use the later, improved '81-on idler arms. You'll have to remove the chain box covers to see what you currently have.

Left side oil line is correct, as Sherwood pointed out...

there's a update on the left side rubber and metal line. the T fitting has been moved inward a bit, so if you order the all metal line, you get the one that fits the updated rubber and metal line, so you need both. or bend the all metal line to fit.

And don't forget the small O-ring on the tensioner shaft to seal the oil line hole in the chain cover.

thanks everybody, i am going to buy new all the lines, the all metal and the metal/rubber ones, so i don't have compatibility problem..

Also buying seals, new nuts, and o-ring so i don't have that tedious leaking anymore.

It's easy to get this left side oil system mixed up when ordering. What Walker means by the "all metal line" is the small diameter line running vertically down from tee to the chain case. After making this mistake, I ended up buying both the left side rubber line and the smaller diameter metal line to match. Replacing them both should eliminate any leaks from left side of the system.

You don't want to try to return something all the way back to California from "Beautiful Buenos Aires". Check to make sure.

Good Luck.

thanks for advice sig_a

I've ordered all the lines from the same page, according to a PET for a carrera 1987-1989. I think, those lines are the right ones.
