That's good to know... I wouldn't think a person from Jersey would ever stop to help a stranger anyways. I'll live my way and you live yours… that's cool. I’ll stop for any stranded Porsche I see,,, including 911’s.

I'd rather have my money in a bank or used it on items that really need replacing or enhancing. I'm glad to have the experience of changing the components myself and learning how everything ties together… I’m just saying I’ve heard this before and wish I would have listened… “if it ain’t broken, don’t fix it.”

The only bad o-rings I found were on the cam breathers. I suppose a small amount of oil might seep out or a little air go, big deal. The only seals that really needed replacing were the ones on all the cam and intake bolt. The rubber cam and intake seals were in remarkable shape. After a little clean up, one would have a tough time picking old from new when laid side by side.

It’s not that hard to tell the difference between hard, dried, cracked or rotten rubber compared to well preserved rubber. I have all new vacuum lines and elbows, but know that many I removed were just fine. Most of the stuff replaced on an intake refresh is not going to leave one stranded… most likely just reduce power and efficiency. Although, it might be a little tough to replace a CPS with the intake in place.

IMHO, time is not the only factor when considering fuel line replacement. I dissected several of the ones I replaced just to see what they look like inside, and they had lots of life left in them. I'm sure you can have 10 year old lines fail at the same time there are probably 35 year old lines plugging along just fine.

Just Porsches? Fair enough.

You know I was just kidding, right?

Sorry, just heard stories about too many 928s burned up because their owners refused to take advice about PM. One lives in the town next to mine and actually caught fire once before it finally burned to the ground. This after several of us implored him and warned him and even offered to do it ourselves if he got the parts. Sometimes waiting until it's "broke" means waiting until it's toast.

We'll have to agree to disagree. The original fuel lines can still have the printing on them and be nice and shiny on top and be on the verge of splitting on the bottom/inside.
So you'd rather replace those and wait for the rest to fail one at a time?
Agree. Most won't leave you stranded, but will cause rough running/rob power. But once they're replaced none will cause a problem for years.
But again, brand new ones properly installed are MUCH less likely to fail, so for less than $100 and a couple of hours, why even consider not doing them?

Yeah, I knew you were joking, just like I was (that's what the smiles are for).

Yeah, a hundred buck here and a hundred buck there added up to well over $2k just to 'prepare' my engine to be blown… LOL.

I plan to have the fuel lines replaced along with the timming belt, the car was started faithfully every month and moved to the end of my driveway, and back in the garage it went, I plan to drive it now on a regular basis so I am going to make sure it is in tip top shape, it may cost me, but hey, thats life
