Triangle of Death Shopping list
 

OK. I know this has been discussed ad nauseum, but I did a search and did not find what I needed.

I have the engine out, and am resealing as much as I can.

For the "Triangle of Death" I currently have the thermostat O-ring, and the gasket for the oil breather.

What other parts do I need to complete this top section?

Thanks so much.

oil pressure sender (for warning light, not gauge)
oil breather hose, unless yours is still supple

I'd also do the oil cooler o rings (3) as they are cheap and job is easier with engine out

And you should replace the vaccum lines.

Good luck,

Good stuff guys, I already did the vacuum lines two years ago.

And I appreciate the suggestion on doing the oil cooler o-rings. I have the two, I will search to see what the third is. Is it OK to do this, or is it one of those things where "if it isn't broken, don't touch it".

Thanks so much.

How are your fuel lines?

Replaced three years ago. Good call!

But I sometimes wonder if they really get bad with age? I guess it is a better safe than sorry call. My tech was insistent on that one.

they do - be sure you have the fuel hoses clamped with something that will not bite into the rubber

be sure the fuel hoses are rated for ethanol mixes

how old are your tires & brake hoses?

motor looks pretty - it'd be a shame to run it and get it all dirty...

Not mine. I'll put up a picture soon.

Good thread, lets get a proper list together.

So for an 85 Carrera I have ordered the following:

oil pressure sender -> 911-606-230-00-M85
Engine Thermostat O-Ring -> 999-707-314-40-M17
oil breather gasket -> 930-107-791-02-M17

Would like some advice on the following...

oil breather hose -> There seem to be a few options.

Also from the picture above, the red plug is the sender, which is the black?

The black is a temp sender.

Don't forget the fuel/return hoses under the tin
 

The fuel and return hoses were routed directly under the exhaust heat exchanger dump. This caused the unwanted (dumped) heat to bake the fuel lines and when i got home on the cars maiden voyage, (550 miles) i had an ongoing fuel leak.

The hose was not quite charred but definitely badly heat damaged. Sorry, can't find the photo.

hth,

Totally good thread. I really appreciate the answers. Now I can prepare my list with confidence. I do not want to have to do this again any time soon. :)

here is my list while doing a clutch job, the trinity (good parts, it does make a difference), I had to use the green "O" ring on my oil thermostat to keep it from "weeping". I also had issues with my vent hose until I replaced it. Look very close between trans and engine for wetness, now is the time to replace flywheel seal, it is amazing where the oil ends up if this is leaking, very confusing. Again I suggest strongly good parts, I know of what I speak, I had to do it twice, use our host or Porsche parts.

Regarding the Flywheel seal. If I don't see oil leaking, should I leave it alone? Or is it best just to replace it while the engine is out?

If it is not leaking that is going to be a "gut" call on your part. How many miles? I think if it were me I would, the part is not exspensive, mostly labor. You know the slippery slope of "while I'm in there".

PS- CCM911, when my new flywheel seal from local parts store was leaking I thought it was the cam boxes or rocker shafts were leaking, that is why I said it is amazing where the oil ends up when this seal is leaking. By the way I know many will not believe this but I have a leak free '84 Carrera, seriously.

Not to worry, it's a temporary condition. As the saying goes, "if there is oil in it, there is oil on it."

we're calling this the "triangle of death" now? hahha..bit dramatic, dont you think?

anyone mention new axle hardware yet?

yeah but for now I am enjoying it, on second thought maybe I better check and see nif there is any oil in it!!!!!!!!

New CV Bolts are already on hand.

And I got "Triangle of Death" from prior posts. Personally, after seeing how dirty mine was, I am tempted to call it the "Triangle of S&!T". :)

Depending on your budget, mileage, mechanical prowess, etc

I agree with automatically changing:
Thermostat o-ring with a green (viton) one, although it takes about 30 mins with the engine in the car.
Oil pressure switch (not sender)

And inspecting, possibly changing
breather gasket
breather hoses (be sure to remove the breather restrictor and install in new hose)
vacuum hoses and clamps
fuel lines (these can crack, leading to a fire that will destroy the car)
rear brake flexible lines
rear suspension bushings (see banana arm)
sound mat
intake manifold gaskets (at least check the torque on the bolts)

And consider changing or servicing:
clutch throwout arm bushings (clean and re-grease)
pilot bearing
TO bearing
engine seal
edit: forgot the oil cooler seals. Someone else mentioned this, and it's a good idea. Might also send the rear cooler out for cleaning and pressure test.

The clutch should outlive the engine seal and pilot bearing. It is the failure of these items that can lead to premature clutch replacement.

And yes, "triangle of death" is what we are now calling it.

how about "Triangle of Grunge" or Black Triangle"?

I had a problem with the "green" O ring...slightly smaller, thermostat slid in with no effort and indeed, it leaked. The "red" O ring fit fine, tighter fit and no leaks. Both are available from our host.
Normally I like Viton..in this case they are manufactured different.http://image.made-in-china.com/4f0j0...Ring-Rings.jpg
