P80 intake manifold gasket (part numbers)

[abscate]

I’ll add part numbers to title today

Picture of an assortment of gaskets all ordered under part number

Bottom is the fitted gasket from Shagg 1999 v70 NA

Some seem correct, some have the upper driver side bolt hole in the wrong place. You can easily punch that hole in to make it fit.

No idea what’s going on with the one with the funny oval cutouts

This is not a critical fitment. The bulk of the mass of the manifold is taken by the steel bracket underneath bolted to the block. Get all the m7x 30 bolts started then push the manifold up and tighten the bracket bolts first to put the mass onto this bracket.

Torque on the m7 x30 bolts is low , 20 Nm ( to be verified )

Is the funny shaped one from a P1 motor? They have that weird plastic up and over inlet manifold.

Haynes says the intake manifold bolt torque is 20 Nm, 15 ft lbs. My car is likely leaking from the manifold because I may have not cleaned the mating surface properly. Or I didn't set it on right. I'll find out soon enough.

Pretty easy to get the little bracket on the far left (DS) bolt stuck under the wrong side of things. I would rather not tell how I know.

In one of Robert's videos he pulls a '98 NA manifold and it has those one-hump-camel bumps.

The specific exercise is tuner stuff for bigger turbos, using NA manifolds, 960 throttle body stuff, &c.
Edit:
Watching his follow-up video putting that stuff on his 850R, the head he has on the car matches the same pattern. I don't remember which head he has on the car now though.

I’ll look at my T5 picture. Maybe the HPT turbo intake manifold is different?

….update, Nope.

It’s not too hard to get a seal on the IM, my bet is on something interfering, as foggy notes above

Alldata says you seat the m7x30 bolts first, then tighten the bracket bolts. Lots of antiseize on the bracket bolts, those guys like to seize

The "one with the funny oval cutouts" is what you need for any P80, 94-98, turbo or NA (and non-VVIS). Its THE standard 850 intake manifold gasket.

Yes, all P80 heads from those years will (of course) match.

I know there were variations on the inlet, but not necessarily where they were used. I seem to recall having difficulty finding the right one for my 93 850 GLT (NA 20V) when I did the PCV on that one. I do recall the later 98 V70 XC was totally different and finally the 00 R also.

Good grief, it could be so much simpler!
