What did you do to your Volvo today? Topic is solved

Yup. Pull the cap and see if there's a bunch of oil in there.

The oil dipstick tube connects right around that area too.

I looked at that. Possibility. There's an oil drip on the bottom of the manifold - unless it's spraying from way down there...
I'll check the cam seal at the distributor. I've had a PCV elbow hose split on my P2 and it really sprayed oil all over the front side, so that's suspect as well.

There's an even sheet of oil running down the side of the pan - a long trail of drips, rather than a big spot.

What is this T and fitting with the red arrow here off the long crank gallery? I found this in a very old MVS post.

I'm pretty sure that is for the oil pressure sensor

That makes sense - it should be the lower one about in line with the crankshaft centerline.

Just did a glove test on startup - it is not inflating the glove, but it's certainly not sucking it in.

I feel like I'm hijacking this "What did you Do" thread. Should I start a new one...? This is almost solved.

No smoking gun yet. The distributor cap and alum housing are dry. The front (cam wheel) end of the block is dry.

Is it me, or does the P2 have a lot more room to see and maneuver under the intake than the 850T? It may be the big ram's horn / barrel intake is way deeper than the flat-ish P2. I could reach the PCV hose clamp on the block from above and to the transmission end of the block on the P2. The starter, the knock sensors, PS hoses, and a lot of wiring in the way. I lifted the car and I'm trying to see with a mirror from below.

The underside of intake runners 1-2-3 are dry. Runners 4 & 5 are wet. 4 is directly above the oil pressure sensor. The dipstick tube is just forward (towards the cam gears) of that on the block. I snugged up the oil pressure switch, but it was tight. The big side hose with the 90º on the PCV is wet, and the block, as is most everything under there. I don't see any cracks in that hose, the clamp appears ok, but so did my P2 when it split.

So I think something is spraying, to get oil on everything, and running off the pan. I think the intake probably has to come off, then you might as well replace the PCV.

You need to get the intake off to determine if it’s pcv leak, oil pressure sender leak, or head gasket leak

Does your dipstick stay seated while you go ham on the throttle? Mine used to eject itself and spray out oil.

The rearward port in that image is to insert a special crankshaft locking tool.

Foof a fine layer of baby powder onto the block and go for a drive, and you should be able to follow any trail of fresh from leaks. You can probably do that with the intake piping dismantled. Might be a pain to clean up, though.

That looks like a high pressure oil bypass dumping back into the pan
