Flame Trap Big Hose Fitting Aimed Toward Block

PeteB · Post by **PeteB** » 18 Dec 2016, 12:55

Doing the PCV repair and the big hose mod, finding that the flame trap cover is
facing almost straight toward the back of the car, or toward the engine block
when it is snapped in. I can put it on the other way 180 degrees but then it faces
the front of the car which cannot work.
The oil safe hose is very stiff and I expect it to just twist the oil trap top back
toward the unlock position.
I tried to unscrew the base of the flame trap to realign it but it is stuck tight.
Anyone else found this issue?
Solutions?

I was able to adjust the air tube position and get it all to go together, but
the small hose hits the throttle linkage. I used a zip tie to pull it out of the way.

It doesn't seem to be positioned right and I can't get the base to move.

Well I have not actually tried the heavy hose, even though I think it is the best solution we have seen and so I encourage others to do it. When user tryingbe came up with the solution, he was working on a turbo car that has a different setup on that end (goes to the PTC, not the flame trap housing). Reading your experience, makes me wonder if anyone else has yet done this particular variant on an NA. Let's see what we hear from others.

Any detailed and clear view pictures of the NA mod trying to be done could help better explain your difficulties. Having a hard time understanding the situation.

I will take some pics today.
The issue is that the hose comes from the oil trap to the flame trap, and is
parallel to the front of the engine. The hose is stiff and the flame trap
nipple faces back not parallel to the hose, an elbow would help but it is
tight in there.
The simple solution would be to rotate the flame trap, and I believe that it
threads into the plastic air tube but it seems to be glued in. I had a hard
time working on it even with the original hose.

It would have been much better if the flame trap cover bolted on in any
alignment position.

Yes the flame trap housing is glued into the intake tube, even though you can buy a replacement housing separately.

Here is a pic from one where I used standard heater hose. Heater hose is of course more flexible but still the angle doesn't look that bad to me, PeteB does yours look different from this?

I drew red lines to show how much more of an angle ours has, I see that yours is
epoxied, maybe I should just line it up better and epoxy it with a better angle:

I think it was just misaligned from the factory.
If I have to work on it again, or if it pops off, I'll see how a 1/2" copper elbow
fits and if it would work well epoxied on.

I'd estimate that we turn the top about 30 degrees to lock it in and a better
angle would be probably 20 degrees back. The hose is tending to pull it back
but I think only about 15 degrees so I hope it doesn't pop off.

I see. That's RTV black not epoxy. I put it on more avoid leakage, than to cement anything. The RTV can just be peeled off if/when you need to go back in there.

Looking at your picture again I'm thinking that perhaps I didn't put the air tube back
on at the correct angle, the large fitting pointing back would become more pointing
down if I rotation the air tube 20 or 30 degrees clockwise facing the TB.
Thanks for the picture Erik.
I see about the RTV.
