Ive got a md 5/16 plenum spacer and yesterday after taking my plenum off I noticed I'm missing 2 of the black rubber washers/spacers..

1) will this cause any harm?

2) are they long gone or like sucked into my engine somewhere??

3) can JUST these washers be ordered from anywhere?

Thanks!

 

You can order from motordyne... just get their "5/16 bolt kit"...

 

Help me understand the question. Do you mean you just received a new MD spacer and some of the plastic spacers are missing from the package?

Or do you mean you had one already installed, and you just re-opened the upper plenum to notice a few of them gone? If it's the 2nd of the two, did you personally install this previously and can confirm all spacers were used? This would be pertinent to your answer for #2...

 

I think he's received a new one with two missing, i wouldn't install it without them personally.

 

i have had the plenum spacer on the car for about 7 months. no problems whatsoever.. i took the upper plenum off and noticed two were missing.

 

Then that's not so great, it's possible they fell off either during fitting or when you removed it, that being the case, they could of made it down the intake tracts.
