I already have the blue Samco hoses, blue grounding kit and several blue Hose Techniques Silicone Hoses for coolant lines and split for wire wraps and dressup.

But I have not been able to find a dress-up for the PCV valve tube on the passenger side of the plenum to the battery box. Is this even made???

Thanks for the help

 

do you have any pics of your engine bay?

 

I'll send the pics tomorrow (monday) when I get to work. I don't have my digital camera cable at home. Here is a link to a pic of the engine bay in progress from a few weeks ago. Since then, I have reoiled my intake filter (blue), removed the silver sheath on the blue grounding wires, and added blue silicone hose to cover some of electrical wire looms running along both fenders.

Here you go.

looks sweet! all you need now is the pi-thon locks.

 

You definetly need to do something with those engine covers, CF ones or have them painted. Kind of throws off the rest of the engine bay. I really like what you have done with the hoses and the intake though.

 

Simstad,
Could you give us the size hoses you required to do the rest of the hoses besides the Samco set. I am interested in following your footsteps. Thanks in advance!

 

If you are referring to the kind of C shaped tube with another bend on the end, thats the master cylinder vacuum line.

 

2003z, Could be that line, it is directly behind and below the passenger side strut tower mount. It is a 10 mm diameter hose that has some sort of internal vacuum valve in the line. But the master cylinder is on the drivers side? Thanks for any help you can offer finding it.

For the silicone lines, Hose Techniques Super Blue color used 10mm to cover the wiring looms and 6mm for the coolant lines at the back of the plenum. They sell it by the foot (10' minimum). It was about $70 for both sizes of the silicone hoses, but you only need half that. I also used 6mm hose and pulled it over the stock grounding wire and grommet at the front passenger side of the engine just below the engine cover. 10mm split to cover the wire loom to the sensor above the air filter. Also, go to Autozone and get their dark blue zip ties which are a perfect match for the Hose Techniques color.

manofsteele2003, I am still trying to decide about the engine and 2 other covers. Until I see something that I like, I'll wait. I just don't know how CF and polished Alum. will look together. I'm also getting the polished Alum. upper intake tube, so I don't want too many different materials. Thanks for the comments.

Randall Patters, aren't the pi-thon locks about $270 for the set, but they do look good.

 

They are worth it! They really spice up the engine bay. You've done a great job so far might as well go all the way! Check out my Z on their web site. http://www.pi-thon.com/toppage4.htm

 

im jealous =(

 

how long did it take u to install the samco coolant hoses...seems like it would not be a quick install since you have to empty the fluids and all...

 

simstad, if you follow that line inside the battery compartment, you will find it leads to the master cylinder. With the stillen supercharger, it had to be re-routed and I just used standard vacuum line of the same size to replace it.

Randall, I'll have samples of my blue powdercoats tomorrow, I've done 7 aluminum plates in various silvers, a blue and a black for the candy blue base. The blue comes in tomorrow!

 

Very, very cool! can't wait.

 

Are the hoses just for looks or do they help with performance? Do they sell it black?

 

solidsnake,
Allegedly they are supposed to be beter than stock, but how much, probably not much. They do sell in black.

Randall Patters,
Those lok's look very nice in blue, something to think about.

ssc,
Not too long, maybe 3 hours, but I also took several beer/smoke breaks.
Got the hoses from Vivid Racing, for $164 shipped. I have since seen them cheaper, check forum GB's. You have to remove the under engine cover, drain fluid (about 1.5 gallons) remove old and install new hoses, fill fluid (using distilled water and coolant) to top, gently squeeze hoses to work out air bubbles, close system start car and warm up, run heater at max, let cool, top off, repeat 2 or 3 times. Works great. Click on photo below, see arrow , this clamp took 30 minutes to force on. I would try a larger clamp if you can find one. Since Samco hoses are slightly larger dia. than stock.




2003z,
How did you handle the vacuum valve that is in the stock hose? Did you eliminate it? If so, any problems due to removal.
Thanks for any input... I think I'm missing something..

 

maybe we are thinking different things here. My car is at the dealer for engine replacement, can you take a close up of the hose in question?

 

2003z,

Sorry to hear about your engine, hope its a warranty replacement!

I'll take a pic of the hoses tonight. I think you are correct regarding it being a master cylinder vacuum hose. I followed it around the battery box, behind the engine compartment wall over to the brake fluid compartment, yesterday. It appears that there is another rubber hose in that box from the hard line to the master cylinder. I think I can move the hose in the engine compartment to the master cyliner to maintain vacuum on the master cylinder and the replace the hose in the engine compartment with a 10mm silicone hose. I'll take some close up pics and post them, just to make sure.

Thanks again for the help,

Neil

 

I finally got everything squared away. I stopped by the dealer today and talked to the head mechanic.
Here are the pictures....Click to enlarge, it should work..

Stock vacuum hose off the plenum for the master cylinder. This hose has a check valve built in the hose to maintain pressure for the master cylinder and routes through the battery box around the firewall to the master cylinder..





Here is the stock vacuum hose at the master cylinder, NO check valve.....



The mechanic said you could relocate the check valve hose from the plenum directly to the hose at the master cylinder, just make sure it is oriented the same direction as the hose was at the plenum..

So, if you cut 2" off each side of the stock hose from the plenum and flip 180 degrees, so it is oriented the same way according to the vacuum, you can put in the location of the stock hose at the master cylinder. Here are the 2 pictures of the silicone replacement hose (10mm from Hose Techniques) at the plenum and 1 picture of the relocated check valve hose.





At the master cylinder




After this, just throw away the stock master cylinder vacuum hose and think how much time I wasted just to eliminate an ugly rubber hose.

 

well, we were talking about the same hose after all, and that would explain why, with the stillen, when you shut the car off, you immediately lose all brake boost. I'm glad you came up with a solution, I will incorporate the check valve when I reinstall. Thanks!

(and yes, its under warranty!)
