This is the 240 81-87 PCV system.





A Flame trap holder

B Flame trap

C Flame trap nipple

D Oil Separator

E Oil Separator Box Return Hose

F O-Ring

G Crankcase Vent Hose

H PCV Breather Hose

Where the hoses go should be fairly self explanatory. Are they not still in place?

I think there is a relocation kit available but someone else will have to explain that.

iPd sells an after market replacement kit for 100$. Not Volvo quality.

Best to get all OEM parts for the PCV.

There is an early PCV piping setup for LH-Jetronic US market B230. You can fit the later version PCV piping parts used on 1989+.

I have the iPd after market PCV relocation kit and these parts are poorly made iwth the large PCV pipe from sort of rotting rather quickly.

Get the Volvo OEM parts.

After 33 years, the plastic bits will be brittle.

There is a drain back tube inside trhe engine oil sump. By now is very brittle and is secured inside the engine using a bracket. Break this, and you drop the oil pan to replace it.

Use the green OEM Volvo o-ring also. I think it is Victor Reinz made.

Questions?

Hope that helps.
