P80 PCV System Repair on a Volvo 5-cylinder (-1998)

Quick question re hose from PCV canister ---> top of engine.

I checked the previous owner's service records, in fact the dealer did the PCV job (changing the canister and hoses).
But the PCV canister ---> top of engine is still stock. I touched it and it was rock hard.
Car runs fine, zero issues.

This is the hose:

My uqestions are:
1. Should I replace this 15 year-old hose. Just rock hard but no leak.
2. If I replace it, is there an easy way to sneak it in (I am not in the mood to remove the Intake Manifold!).

If you can blow clear through it and it still snugs down fine to the top of the head, leave it alone. There's no "easy" way to get a new one on without removing the intake manifold.

It is a bear to replace the P.C.V. system. If your hoses are rotted I would recommend doing the whole job. it took me 6 hours to do. The walkthrough is wonderful. I had chunks of dried oil in my crank box that looked like asphalt and the holes were almost completely plugged. My fire trap was completely plugged and the hoses going to it were rotted and broken, almost non existent.
The person who owned the car before me severely neglected the car. I am giving it love and care now and it is a wonderful vehicle. I LOVE my Volvo!

Update on my situation. I have checked the IAC valve. It was pretty clean but I hit it with carb cleaner anyway. Rechecked the injector connections and all are solidly attached. Fuel rail connections tight. Unplugged the MAF and the car would not start at all. Plugged it back in and it would still start but runs rough as before. Let me know oh gurus if you think of anything else I can check. Think I might tow it to my local mechanic tomorrow.

Is the bracket on the right side of the intake manifold (lower screw, closest to the throttle body) stuck in between the manifold and the gasket?

[headhunter]

I don't think so, I just went and looked. I felt all around the connection between the manifold and block and I think I have a good seal. Also haven't had any fuel smell which it seems like I would if I didn't have a good seal.

[jblackburn]

Hmm...aside from double-checking every turbo hose at each connection, I'm out of ideas! The two that attach to the intercooler like to blow off pretty frequently.

Is the throttle position sensor plugged in, if you happened to unplug it?

[headhunter]

Turbo hoses are good. I didn't unplug the TPS. Just went and double-checked in case it came undone but it is plugged in. Thanks for trying to help jblackburn, I appreciate it!

BTW your tutorial with pics is awesome. Thanks a ton for taking the time! I am taking this sucker in to the mechanic with my tail between my legs. Will let you know what it was. I am sure I left something undone or something.

If you have not tossed in the towel yet, you can go back to the basics. If the car starts, check compression. Maybe one of the cylinders are low (burnt valve - yikes).
