Got the kit.....Looks good, Thanks for all your effort Jim.
Plan on digging into it this weekend.

I will be replacing my Fuel Pulsation Dampener as well. What's the best source for this part.....the dealer?

 

Malloy - $106. Although I found one here in the classifieds that was bought but not used for $85.

 

Well the FPD is kindof a bitch to get out..... I was able to get it out ok but did have one casulty in the process. There is a small amber colored hose crimped to a tube in the side of a vacuum fitting on the block just behind the FPD......This colored tube broke off at the crimp when I pulled the FPD. It looks like it has oil in it....

Any ideas what and how I can replace it?

 

PCV Valve Question.......

Should the PCV valve sound like something is loose inside? Do I have a Bad one?

 

Yeah, it's a ball and spring check valve. If you blow on one end it should close completely, that's all.

 

That's an oil metering line. You'll need to replace the whole line. Maybe you can find one used. Parts N3A1-14-660, N3A1-14-660A, N3A1-14-670, N3A1-14-670A. I'm not sure which one is which or why there are 2 part numbers for each line.

<mwuahrgahra ... it rises from the dead...>

Just finished my viton hose / grounding wires / FPD job. Except for the fact I left the idler pulley nut loose for a minute, everything went together perfectly. It took a while for me to be happy the coolant system was full, but finally on the road test I got a good 10-7-10. (My turbo control actuator is a little slow).

The viton really grips well. Almost too well in some cases, but a touch of saliva on the nipple makes it work . It's fairly abrasion resistant and very kink resistant. I'm very happy with it and I still have plenty left over.

I wrote down the length / dia I used for each hose and colored in the check valves and uncolored hoses on the vacuum hose diagram.

Way to go Dave. I finished mine last week. Similar feelings about the hoses. The job came out very well for me too. All was fine except that I copied one error that was in the previous hose job and still had the same problems: 0-0-10. Hoses to the TCS were reversed so the vacuum was lost under boost.

I went with the zip ties. I did find that screw clamps damaged two of the larger hoses because I tightened them too tightly. The nipple at one end of the line was smaller than the other. Ended up using different size hoses and joining them with brass. I am very happy with the hoses and finally my car runs GREAT. Perfect boost.

I am really happy you guys like the product. I am glad I didnt go out and make 40 kits though. I still have 6 or 7 left, so spread the word guys!

 

I know this is kinf of off suject. What are your guys feelings on Viton O-Rings? Are they worth it? Any idea what the sizes are?

Thanks

 

I'm riding your coat-tail on this informative reply. Your remarks are consistent with a very useful table of per-chemical elastomer performance. [making note to post a link from home].

After buying many meters of colors and diameters of quality silicone, I realized I really want some lines to tolerate exotic fuel blends, such as a fluoro type.

A buddy's vacuum lines on a 12A, maybe not the best grade silicone, a couple hundred hot oily hours later, have portions of the same lines both too soft to efficiently maintain vacuum and hard enough to split if flexed.

 

I have 14 years worth of chemical resistance charts for every elastomer and nearly every chemical as of the mid 90's. If you need to find the resistance of a certain chemical let me know what it is and I will find what is best to use in that application.

Silicone is a great material. It actually accounts for over 90% of our overall business. It has great peoperties, but just like anything else it has its limitations. It appears that most people what a silicone hose because it can be colored to match the car or other components under the hood. Since Viton cannot be colored other than a "manilla folder off white", brown or black, I am working on a way to co-extrude silicone over a viton ID. This would allow for special colors and have the benefits of Viton protecting the silicone from the oil/fuel contamination. The problem is the expense is probably going to be too high. After I am done with one trial size I will then decide if anymore time should be spent on the project.

High Temp,

Do you have any more Viton kits left? If so I would like to buy one.

Rob

 

Contact Jason at RX7store.net. He may have a kit left.

We need to run these in quantities of 20ea at a time or the cost on the raw materials gets extremely high. IF we can get another 20 kits I have no problem doing another GB.

Jim

 

So is there a new group buy scheduled ? If not, anyone have a kit for sale ?

thanks,
:-) neil

 

We can arrange for another GB at anytime. We just dont like to keep too many of these kits tied up in inventory due to the cost. If we can get 10 I will make another run.

Thanks
Jim

 

Ok we are going to make a few changes to the Viton Hose kit. Based on the advice from dgeesaman we will look at reducing the quantities of the hose to make the kits a little more cost effective for everybody.

We are proposing that the new kits include:
30Ft 3.5MM (old kit was 40Ft)
12Ft 4.0MM (old kit was 15Ft)
12Ft 6.0MM (old kit was 16Ft)
4Ft 8.0MM (kept this the same)

If the above new kit is not acceptable, or if anybody thinks we need to change the quantities please let us know. These will also be placed on our website as soon as we get them finished.

The price will be changed from $276.44 + shipping to $236.00 shipped anywhere in the lower 48 states. We have enough raw materials on order to make 10-12 kits at this point. If we have more 10 request for viton kits I will need to order more raw materials or run more 3.5MM.

Lets make a list on who wants kits. I anticipate being able to start shipping kits again in 7-10 days.

If its under the hood it has to take high heat, if it's on the block, it should be made of materials with properties like silicone, viton or teflon. My rubber K&N's are about toast.

here are some numbers from my viton job back in 12/2000:

all durometer 60, on one tight bend I put a pen spring in for support but could of looped the tubing using a little more. I bench tested the 1/16 wall with lots of vacuum and was satisfied that if careful it would not collapse, before choosing viton I pm'd a guy who chose 1/16 wall and he hadn't any problems. have to use the 1/8 wall where it would be hard to push on like down on the engine block by the fuel rail. the 60 durometer was the right elasticity.

new viton will split if injured, usually within a few hours. I dont advise using pliers to help push it on the fittings, yes my fingers were sore for days. stretching the tubing ends by inserting a lubricated countersink nail punch helped immensely, so I applaud your metric sizing which I don't think was readily available. after a few months the tubes will hold their form over their fittings, and after 4 years they are still supple.

If you plan on going single turbo you probably want to save your money and use silicone since you'll get to eliminate much of the rats nest. DamonB said his silicone tubes are still supple even after an engine fire and more miles. $50 vs $220.

Some have asked for a viton kit

Mc Master Part No. Description feet used
5119K48 1/8 ID, 3/8 OD, 1/8 wall 9
5119K41 1/8 ID, 1/4 OD, 1/16 wall 19
5119K49 1/4 ID, 1/2 OD, 1/8 wall 4

I believe one has to order in 5 foot increments from mcmaster

High Temp Silicone, can your people make coolant lines? or passenger side engine mount material? or housing coolant seals (I think peter farrell tried various materials like viton and teflon encapsilated)?

do you know people who can make better wire insulation and connectors for engine harness?

 

If you purchased that list from Mcmaster Carr the total would be in access of $203.00 and you would receive less than half of our kit. Also we are offering a heaver wall on the 3.5MM.

We are not currently setup to manufacture radiator hoses. We can however compression, transfer and injection mold various materials. For something like a teflon encapsulated seal I would suggest that you look at Parker Seal. They probably keep thee types of seals in stock.

 

Hightemp, I was too lazy to read through all 10 pages lol -_-. So I was wondering if your ever got into the making of these hoses? If you did, I'm sure that I'm interested to get the hoses. Maybe this would have been better off as a PM?

Jeremy

 

To be honest a new thread should have been started. We have already made and shipped the first batch of hoses. We are now on the second run of the viton hoses but we have made a few changes. On the advice from members here we have reduced the amount of hose in the kits because there was a lot of extra un-used hoses. The new kits now have a little less hose and a more cost effective price.

I am only making enough to run 10-12 kits and then have a little footage left over of each size. Right now 2 kits have already been pre-sold. I will put you down for the third.

 

Sign me up for a kit. PM with what the payment conditions are (paypal, personal check?)

HT - you think a Kalrez version of this kit would be of any merit?

 

Svelte 7,
You are signed up!

I think Kalrez fluoroelastomer would be a good solution like Viton, but it would cost more and is typically manufactured in harder Durometers (75-95). It actually can handle more heat than Viton, but I am not sure that the costs would fly for this application.

I havent worked with it much because of the cost factor.

 

Ok we have run all of the Viton this afternoon. We are going to get it all washed tomorrow and Monday so we are looking at the beggining of next week to ship this kits out.

 

can I look for you to be a source of coolant lines in the future? I just replaced a line on the turbo that was in suprisingly bad shape after 12,000 miles.

I was considering steel braided next go round. do you know rubber type material steel braided lines are typically made?
