Cyclonic Trap Bolt Removal

[radiopilot]

I know this has been discussed and I researched every thread on the cyclonic trap cleaning, seals, installing it correctly, etc, but I did not read on how the bolt was removed... I tried to take the bolt out but could not get it out because of interference with the intake or some other part (injectors)... this is on a FI 1982... has anyone been able to do it without removing a lot of other parts?

If I'm successful I will install a threaded stud and use a copper washer/nut to install the trap back on... it'll be easier next time to remove and clean... has anyone done that also?

Thanks...

I haven't had any issues if I remove the trap with the bolt still in it

I didn't measure the clearance, but it sure looks like if it were a stud tall enough to put a nut on you wouldn't be able to put it on or take it off without hitting the bottom of the intake manifold Nick. Although maybe if it were tilted sharply it would clear. LIke Mark says, it comes right off with the bolt still in it.

I tried both taking the bolt off and taking the bolt and the trap together off but could not do it... neither way allowed me to take it off due to hitting something above... I was ready to cut the bolt off but decided to bolt it back on...

The stud would be installed first and locked in... then the trap would just fit over it leaving perhaps 1/2 inch of thread so a lock washer and or locknut could be used. It would surely make it easier to remove the next time... I think...

OK... removed the cyclonic trap, cleaned it and installed new hoses... now school me on where the oil goes when the vapors are seperated... where does the oil go? Are there weep holes under the trap on the engine side where the oil drains back into the crankcase? Is so where are they and if clogged would the oil travel up into the hose? Would it need the flame arrester to prevent this oil from seeping up into the intake... not a lot of oil but a concern... I'm getting a small drizzle of oil in the plenum and deciding whether I should buy a seperate oil catch can to prevent this oil from being sucked into the intake and burned which to me is not good for the intake or downstream... plus would it not kill your oxygen sensor faster (I've been torching on the sensor to clean it up with very good results)? I no longer have the Cat and have installed my own test pipe (removable of course) so no worry about oil vapors destroying it.

Thanks,

The oil/gas mixture swirls, and the lighter (gas) goes to the outside and exits, while the heavier (oil droplets) go toward the center and drain back down a big .5"+ diameter hole into the crankcase. The hole is off center on about a 45 degree line toward the rear of the engine and away from the center of the engine.

Alvon,

Thanks... I see it now... took out the service manual and see the internal pipe... I guess I need to take out the cyclonic trap again and run a wire or pipe brush thru it and any weep holes to clear any obstruction or caked up oil... running much better since cleaning the trap though... I ordered the oil catch can and will use it between the cyclonic trap and the plenum inlet so that I insure only vapours are collected in and not oil.

Cheers,

Nick
