Ford 24lb SVO injectors are on the way!!! Feedback?????

Actually a smidgen of high temp grease works better then oil...

 

[tntcorvette]

actually the instructions call for wd40

 

[Eagle85C4]

WD-40 will dry up after a while...and is conducive to attracting dust and dirt, whereas hi temp grease in it's gelatinous state is not readily prone to breakdown and dehydration due to it's higher tolerance to heat. The MSDS for WD-40 has it's flash point at 110° F. A typical can of hi temp white lithium grease is at 393°F.

From www.wd-40.com;

"How long does WD-40 last after application?
While this may vary depending on the application, WD-40 remains effective even after it appears to dry. The corrosion and rust protection ingredients remain adhered to the surface. External conditions may, of course, require additional applications of WD-40 for maximum protection."

It is suggested for use for it's ability to provide lubrication, whereas the hi temp grease not only provides the same lubrication but also provides a sealant quality that WD-40 does not provide.

Correct me if im mistaken, but the job of sealing off fuel is that of the rubber o-rings & the natural compression of the fuel rail system.

WD40 is only used/suggested to make it easier to "slide" the injectors into the manifold.

That is true, but have you ever heard of the term Insurance? If you reread my post I said WD-40 is suggested for it's ability to provide lubrication to aid in installation, but by using hi temp grease you get a secondary "value added" if you will...extra sealing capability, which also provides a coating encapsulating the oring, that won't dry out as the WD-40 will do by it's own implication from the manufacturer, and the grease also helps the oring from drying out as well as aiding in it's removal should that become necessary.

just to give everyone an update the 24lb svo injectors are doing great! Well worth the money and based off the feedback i've received from here & the vette.net the accell units have a bad rep. while the ford units have a good rep.

The car sooo good with these new injectors.

now im paranoid....im going to call tpis tomorrow and ask about replacement o-rings and where they get theirs from. But like I said earlier, i've used o-rings from home depo before w/o a problem. But I dont need a fuel line rupture at high speed, or period.

Anyone care to chime in on this?????????????

Yeah, my rubber-fluid compatibilty chart says Buna-N is Good, for gasoline, Neoprene is "Fair" (would probably work fine in an injector, where there's no relative motion) and EPDM is a big "No Way"!
Other "Good" compounds are of course teflon, nylon, and Hytrel.

Wonder what you got at the Depot, since all these compounds are good with water?

BTW, I just visited the Home Depot website, and learned their O-rings are Buna-N; sounds liike you're OK!

Yep! I had a feeling the home depot rubber o-rings were fine since I used them on my super ram cold start plug.

shows the one's I got and they are Buna-N. Click under product category #1 and its the type #83 o-ring by Danco Company.

Only $.47 each!!!

I actually never ordered the replacement one's from TPIS. Guess I saved some money.

Talk about a margin mark up!!!! WOW!!!!
