Hey everyone. Have a YS 140L in my Olympian, with the Central Hobbies wrap around header and brace. The pipe is soft mounted with a PAC clip.

Problem is I cannot keep the header from coming loose. Lost one today and the previous one had the flange tore up from coming loose repeatedely. Have tried using Lock-Tite both Blue and Red, have tried using extra copper washers to ensure snuggness. At $40+ a pop cannot go on this way much longer.

Really like the wrap around header and don't want to go back to Hatori, unless absolutely necessary.

Does anyone have any suggestions. Thanx in advance.

How many copper washers you using?? I put in two and tighten it really tight and dont have a problem with it. I will usually get 500 flights before the little flange starts to come apart, but very rarely do they come loose on me. One thing to try is to get the pipe more rigid, could be that your pipe is moving more than your engine transmitting that back to the header causing it to come loose, cant hurt to try it. Other than that man, I am not sure what would cause it.

Ed,

Might be a suggestion here.......make sure that when attaching to the header brace with the clamp the nut on the engine is loose...This will allow everything to seat. Also try an extra washer...I know you have said you used 2 what about 3 or 4....I had a special brass washer made that is about 3/32" thick and it doesn't compress like the copper ones but still is soft enought to make a good seal.

The deal is perhaps the nut is bottoming out before the header is really tight enough...Also when removing the header go with new washers....The old ones are compressed and will not give as good as fit.

Then if the brace is installed and nut tightened afterward the force should all be on the brace and not the nut. Just a thought...maybe the nut being tightened before the brace cinched down could be puting some force on the connection.

Give it a shot...........

Hey you going to Phoenix?

Thanx guys. I have tried 2-3 washers making sure the nut bottoms out.

Usually tighten the nut then attach to the brace so will try the other way, makes sense now that you mention it.

Am repairing the pipe mount right now so that may have been a problem without me knowing it.

Time will tell.

Phoenix has been in the back of our minds, but 14 hours and almost no practice make it questionable. I did ask off next weekend for it and Joe would go, if we get some stick time in. Right now can only say questionable..

Again, thanx guys.

Plumbers teflon tape works for me. One to two wraps clockwise on the threads.
