1987 240 Flame Trap Question

[elarcoiris]

Hi,

I managed to remove my flame trap by just putting my arm under the manifold and I've given it a good clean with carbi cleaner, as well as cleaned the hoses and everything came up well. My question is, the smaller port coming out of the flame trap, should this have flow? It is completely blocked off and I don't know whether I should try and force something through it or if this is how it is meant to be? I can't see an exit hole for it on the inside of the flame trap?

Thanks in advance!

Vacuum nipple should be clear. Get a needle and clear the crud out.

Thanks, I decided to push through this morning and couldn't believe how compressed and hardened that stuff was to completely cover and block the hole. All clean now, but looking at the muck around the separator box, I'm guessing I should replace that while I'm at it.
Or is it fine to clean and just purchase an O-ring seal?

Just clean it out and get a new O-ring. The original equipment separator box usually lasts a lifetime.

On any of the 240 PCV systems I've taken apart, the flame trap hose from the separator box is always hardened.

I've had good luck with this one https://www.eeuroparts.com/Parts/48123/Flame-Trap-Kit-23439601/ The MTC hoses are crap because they have a seam on both sides that can crack.

or go with Volvo for the hose (better quality): https://www.fcpeuro.com/products/volvo-flame-trap-hose-240-244-245-740-780-940-3501708oe
