I have been PM'd numerous times asking what I used to seal the plenum.....First.... I don't mind the PM's at all....but I thought I would post here with the info so you won't have to wait for me to respond....I used Permatex red high temp sealant..... below you see permatex ultra copper which I think is a bit better......just apply a thin film and use patience and finesse when torquing down the bolts.....Ed

 

ooooohhhh, nice

I should look into small packets of this stuff to include with the hardware, I think it would be money well spent.

We did some testing on the new inserts today, so any type of plastic compression or cracking will NOT be an issue anymore. You can crank them down now with no worries. The sealant is a great idea though.

If anyone has a link or can point us into the right direction as far as getting small packets or tubes of this stuff I am all ears.

Thanks for sharing the info. While I dont think it is necessar with the new revisions, better safe than sorry.

Revised plenums will start shipping tomorrow, thanks for the patience guys.

 

Here is what I used... it worked great. I highly recommend picking some of this up for the plenum install, its only a few bucks and worth the peace of mind...

 

is this product available everywhere or some special kind of stuff?

 

what version of your plenum are you guys up to seems like your trying to perfect them i was considering the crawford but iam thinking about waiting . do you have any plans for more revisions?

 

no, none that I can think of. We already did testing on our insert revision with great success.

We are confident with everything we have lined up in our production.

 

Any auto parts store should carry these.

 

That's the exact one I used! Thanks for your tip Duflacci!!

 

will using this void any warranty on the plenum?

 

Nissan would tell you, call them up at the customer support #.

 

Thanks again Duflacci (from one of your numerous pmer's)!

 

If need to dope up my plenum to get it to work, cancel my order. That is nothing but a pain........

 

A pain? Squirting a thin bead of a substance around the perimeter of the plenum takes 30 seconds or less, a FRACTION of the work required to swap plenums in the first place...

 

Yes, pain. If i'm buy a product that has a gasket already, and it needs more silicon to seal, that doesn't sound good to me at all. It may seal that way, but having to use it in the first place tells me somethings not right about the way parts fit together.

 

VFR50,

The kinetix plenum does NOT require sealant in order to obtain a proper seal. Some people have just decided to use it for extra insurance against unlikely leaks. Furthermore, if you were to order now you would end up receiving a version 2 which can be torked down much tighter and virtually eliminate the possibility of cracking the plenum.

 

cinergi 1

according to the above post, lsdunique is looking to trying to find some small packets of silicon and include them. My order was placed last month, and I have not recieved any shipping info, but was charged for it last month, great. lsdunique seems to be confident that the new ver 2 will not crack, but does not sound that way about the plenum sealing....

 

The plenum does NOT leak if you torque it to spec. The reason your plenum is delayed in shipment is because you are getting a revised plenum that can be torqued tighter than necessary without cracking. This will ensure against leaks. You will be fine. Had you closely paid attention to the posts regarding this issue, you would already feel confident in this. My plenum does not even come close to leaking and is sealed very well all the way around. Of course I cracked mine a tiny bit near a bolt hole but I have ordered another plenum so I can have the revised torque happy version and tighten it down to my preference. The only reason you will want sealant is if you get the 1st version and do not want to tighten it too much for fear of cracking it. Once again, my 1st version does not leak, but it is overtightened. Once again, you will be getting the 2nd version so this is not an issue for you.

 

I am only looking into the possibility of supplying some silicone.

I know it doesn't need it. The problem with obtaining a seal before was that the tolerance between the torque that was required to get a seal, and enough torque to crack the plastic was small, so finesse was needed.

Before, you had to be careful and give a torque at about 36 inch/lbs or an equivalent 3 ft/lbs

We just did some fine tune testing and the new revisions will allow torque ratings as high as 120 inch/lbs of torque or the equivalent of 10 ft/lbs of torque. We could even go higher, but we actually sheared off a bolt before getting another reading, and the plastic still showed zero signs of compression or cracking.

So, we dont think there will be any problem getting a good seal with our new revision, and that is without the silicone.

We are recommending a torque rating of 6-7 ft/lbs of torque or about 80 inch/lbs of torque. Without a torque wrench, I would say use a 1/4" drive ratchet and using one hand, tighten the bolt down with good force. Good force meaning a normal person like myself grabbing the ratchet with the head just sticking out of the left side of my hand, crank it down pretty much as hard as I can.

So, I apologize for worrying anybody and any delay, but we are back on track as of today and everything looks great. Some people have passed on the revision and are still getting great results with no problems.

 

LSDunique, what would you say was my problem.

I torqued very carefully to avoid cracking but had to keep going to try to get rid of leak and started to crack the plastic and still had a leak which I ended up applying some sealent to the splitline.

 

lsdunique, thanks again for great information. I get my Z back next week and will install the plenum then. I think that a small of silicone certainly cannot harm anything, but is in fact jsut cheap insurance against future headaches. Look forward to receiving my plenum and the installation within the next couple of weeks.
