Gday,

I have welcomed my knuckles in to 928 ownership over the last few nights, i returned my unused 3T jack stands and replaced them with 6T, this being my first foray into lying underneath a car (of my own volition...) I must say there was some trepidation, however, I laid my yet to be restored Teledials under each wheel (wheels left on car) for added protection, pleased to say now after some hours under her (there is another thread here somewhere for jokes ta!!!) I am feeling totally relaxed now. Underside revealed little to worry about, but I had a good look at how to tackle my motor mount job which is impending.

Anyway, those fuel lines!!!! topside forward nuts tight but heaps of room for leaverage so no major.

Underside rear... unbelievable!! I vowed I would not become agitated during this job, and reading some of the "old hands" posts I thought I have got this... Well I kinda did until around hour two when the first of my skin attached itself to the header bolt!!!

I tried every imaginable angle to crack that nut, to the point of unfathnomable distraction and pain, this included numerous trips back into the lounge to calm down, Tania thought this most amusing, of which did not help.

I then left everything for a day, after spraying CRC over the joints (I think you call it PB Blaster or similar)

Tried again last night same result, gave up, more CRC.

I then cut the hose so I could use a socket, reading that on this forum was a duh moment for me!!! I think The Deputy mentioned if you do this then you need to complete the job as the exposed lines will attract moisture, hence rust, Oh and whilst I mentioned Brian, I could not source the "line wrenches" in NZ that you have over there.
The socket did not work either as I could not get enough swing or purchace whilst holding the 17mm spanner to the male end at the same time, I could have spent more time on getting this right though I guess...

I did some thinking meanwhile and thought, right, I cannot use heat via a naked flame eg: blow torch, a heat gun would not fit, well mine wouldn't, and besides it is not "direct" enough to just heat the female end I am targeting.

SO this morning I heated up the end of my wrench with a blow torch, well away from the car or ignitable fumes, of which there weren't any, I got it hot but not to the point of major discolouration, then I simply placed it over the nut and left it for 1 minute to let the heat "absorb" and swell, I then took it back off and used a "cold" wrench, CRACK!!! OFF SHE SPUN!!!! I did the same for the other one with exactly the same result, with minimal effort.

Tanz came running into the garage when she heard me!! she thought things had gone wrong, nope it was the cry of unbridled joy and exhilaration!!!

Anyway, that's it, thanks to everything I have read on this site, invaluable to say the least, next up is the fitting of my new accumulator, then some under-body cleaning, replace a couple of very "green" looking grounds I spied under there, even though overall it is very dry and rust free.
Then POD out and onto the kitchen table with a quiet beer to replace my odometer gear.

I still have not managed to work out why I cannot upload multiple pics (previous one just gets superceeded when I try) anyway at the risk of boring you with another fuel line pic, here is the (sorry not my best photographic work) very reason I needed to replace these 38? year old lines.

Oh and when you see a spanner falling toward you whilst you lay on your back move your head out of the way!!!
Cheers

Great story! I find swearing to be very therapeutic when I'm working on my cars, so I can relate to going inside to cool off. I'm also an expert at dropping dirt in my eyes, and bolts, nuts and spanners on my face.

Look forward to hearing of your continuing progress.

It's worth getting a can of freeze spray (electronics outlets have it for circuit board testing, and you can also get a Loktite product), which is also useful in thermal shocking a bolt, stud, or nut. I alternate between heat and cold on stubborn ones.

To post multiple pics:
1. Click 'Go Advanced'
2. Click 'Manage Attachments'
3. Click on the first 'Browse' button .. and then select a photo on your computer.
4. Click on the second 'Browse' button .. and then select your next pic ... and keep going until you have selected all the pics you want to post ..
5. Once you have selected all your pics click on 'Upload'
6. Click on 'Preview Post' to see how they look ... size, etc

Another way is to insert a url to any pics you have on the RL server, or on a photos sharing website like dropbox etc. If you use this method you can insert text between photos ... with the previous method they all appear after the text, in the order you added them.

Cheers Dave,

Ah!!! maybe that is my trouble, i am hitting upload on every pic...

Once I sort the pic thing out I will post more of my progress, I think the motor mount job is going to require lots of beer...

Glad you were able to succeed, with the heat-the-wrench trick. Use the technique once in a while, but have never mentioned it here. Since you have to be careful you don't get that wrench to hot, flash point for "right conditions/fuel-air mixture" gasoline is around 800 degrees. A heat sourse will ignite fuel, spark is not always necessary. But, it doesn't sound like you were close to that temp...fortunately. Just thought I'd mention it, so if anyone was following along at home...they might get carried away heating the wrench...and have a problem.

Anyhow, glad everything finally came apart.

Also, there is nothing wrong with using extra precautions while being under a car. While mine are on jack stands all winter, if I decide to work on one of them...I always slide the 2 ton floor jack under the end I'm working on. Safety first, is a good rule to follow.

Looking forward to more pictures and following along with your projects.

Brian.

Thanks Brian,

YES, I had a long think about whether to even mention the heated wrench, I would hate for anyone to try that and get it wrong, POINT TAKEN and probably best NOT RECOMMENDED as a rule, I made sure my fuel lines were "dry" but I know fumes can be lethal when ignited.

Aside to that, I will be 90 whence next it's due (unless Roger and Greg are handing out "lifetime" guarantees!!!) so I plan on getting my son to do it for me!!!!

Once again thanks, as I have gleaned a lot from your posts.
