Title: Mileage update, 1,244 mi later...
Post by: Andy Illes on October 08, 2004, 11:33:12 AM
... that's NY to home, 91.54 gals total (half tank left).  Back in Loxahatchee (W. Palm Beach)... or rather, what's left of it after 3 storms.  Uneventful trip, except I left my (coach) keys in the gascap during my fill-up in St. Pauls, NC.  Duh!!

However, if I completely topped my tank off, I had a really serious fuel leak out of what I presume is a charcoal canister that's on the passenger side of the engine, behind the front wheel.  Anybody else have this?

Thanks for everyone's help and support with all my dumb questions to make it such an uneventful trip... y'all's the GREATEST...  :D

Andy that canister is for smog what it does when your parked it keeps the fuel vapers from excaping into the air  it stores them then the next time you start the engine the engine pulls the vapers in and burns them, if its leaking I would recommend getting it fixed asap raw gas by a hot exhaust pipe and a propane flame of the refer bang bang no more clipper :D

Thaks Jim.   Can I just remove/bypass that thing... or do I need to replace it?   Remember.... no "smogging" necessary down here.

Again, y'all are great... thank you.

You can but I wouldent it keeps fuel fumes and vapores from going into the house and engine area it's one of the few good smog devices :D
Title: Charcoal canister
Post by: Andy Illes on October 10, 2004, 04:43:29 PM
Hi Jim and all.

I'll take your counsel and keep it, Jim.. thank you.    However, I called all the larger parts houses and they don't even list a charcoal canister for this thing ('76 360)... ditto the Dodge dealer - no longer available.   Does anyone know of any "generic" one that would work?   Or a part number for this one, or an interchange?

Btw... I just started hearing an exhaust manifold leak (pft, pft, pft sound, sortta like a lifter ticking) after I got home, I THINK on the driver's side.  I already picked up new gaskets but haven't looked at the thing yet.... any tips/shortcuts, etc?  Anything else I should fix while I'm at it that's easy/easier to get to with the manifolds off?

Thanks again, Andy

Check the local junk yards.  That was a multi year item on these rigs.  Any similar dodge/plymouth van of that era should have had it.

Thanks for the reply, Conrad.   I sortta thought of that, but wondered if I wouldn't be buying the same problem with a used unit.   What do you think?

Thanks, Andy
Title: canister
Post by: Conrad on October 10, 2004, 09:24:00 PM
When you mention a 'serious fuel leak'  from the canister, how serious is it?  The canister is supposed to collect the vapor from the carb (not the liquid gas) as mentioned before.  If you are getting leak there, i would want to know the reason why the liquid form of fuel is where the gaseous form should be located.  Sumptin' don't sound right.

Post by: Andy Illes on October 11, 2004, 01:53:13 AM
How serious?  By the time I noticed it Conrad, I'd guess at least a gallon had leaked there, it was quite a steady flow.   Fearing a catastrophic fire, I pulled away from the initial puddle at the pump and just on a hunch, opened the gas cap again and that seemed to stop the flow (btw - the flow had diminished quite a bit by then).   Again, it only happened the two times I really topped off... meaning until the fuel level rose right to the filler level.  I have no idea how that system is supposed to function.... where lines run from the tank to that thing, or anything else about it.... but yup, the canister certainly is getting raw liquid.

Any suggestions what I should be looking at and fixing?

exhaust leak.........
I wonder if all that driving with the advanced timing had anything to do with that?
From what I understand, advanced timing will make you run hotter.......

hmmm.............

also (and this escaped me earlier) your cannister should absolutely not have any gas it in it - sounds like someone got some hoses crossed up or something - but like Conrad said - get this addressed asap

but heck - with gas prices they way they are - maybe I'll go to 6btd and see if my mileage improves - heh!

Well, it does have raw gas in it.  I have NO idea how the hoses are supposed to be routed.  It's not running out of a large 90* rubber "elbow" jobbie on the end of it, but rather, it seemed to be coming from somewhere in the middle of the canister.  All suggestions welcomef.

As to the exhaust thing, I wasn't running "hot", at least as far as the temp guage showed.   I think it's just age.  I don't see any obvious signs that anyone's ever messed with the manifolds, and the gasket(s) just might be getting old and tired.... like me.  :cry:

OK I got out the old trusted Dodge maint manual and heres what it says looking at the tube side of the canester the upper hose goes to the crab the midel hose goes to the tank and the bottom nipple is capped off with a cap that is probaly where your leaking fuel if you have three lines the bottom one goes to the carb bowl but thats only for light duty vans this is from my 77 and for the 360 what is supose to happen when you start up on a hot day all the fumes from the carb bowl go to the canister as well as vapor from the tank, then when your under way the carb pulls the vapor out of the canister and is burned. another possiblty is your over filling the tank on a warm day and before you burn down some the gas is expanding and filling the can this can happen  just follow the hose but #1 get a new can or replace the tubing please do not run that thing untell you do also before you start working on this thing open the gas cap and vent the pressure  remember everone ever one of these Clippers were made in Calif and all have Calif emiisions no matter where you live  good luck let me know what you find hope this helps :D

Once again, Handyman dons his gleaming armor, mounts his sturdy steed.... and thunders to yet another rescue...  :D  :D  Thanks, Jim - you're truly priceless!!!

Yeah, it's an absolutely must-fix-immediately thing.  "Clip Flambe" just doesn't sound appetizing.  I guess God WAS my copilot, huh?

The hoses/connections are ok, it seemed like the fuel was coming from the top of the canister - meaning the canister itself is probably shot.  That's why I'm asking if anybody knows of a replacement unit.  However, from your description of what it does though, it sounds like any canister that fits would work... ya think?  Most that I've seen mount vertically with the hoses connected at the top, whereas ours mount sideways with the hoses on the sides.  Wonder if that makes a difference?  Would one of the vertical-mount ones work ok sideways?

From how you describe that circuit, it's puzzling how/why that thing's getting raw fuel to it, never mind in that quantity, huh?  Plus, it wasn't just drip, drip, dripping... it was a good, solid stream.   It was mid-to-upper 70s the whole trip, so I don't think it's temp related.  Rather, since it only happened the 2 times I topped it off right to the filler opening (and remembering that the filler is at about the same level as the carb, I'm thinking it has to somehow be level-related - or maybe even siphoning?  

Hmmmmm...  :idea:  it just now hit me that the amount leaking out would seem to be about what the filler hose would hold above the tank level, huh?   I just went out with a flashlight (it's 5:30am here), and the canister seems to be at about tank-top level.... where the hell's my laser level when I need it?!?!?!

In case you haven't guessed yet, I'm onna those insufferable jerks that just HAS to know "why", lol.  I'll get on it after daybreak and keep ya posted.  Still have to find a canister though.... sigh.

Thanks to the hurricanes, I'm unfortunately full-timing at the moment, so it's gotta get fixed pronto.

andy try thr junk yards first if not try NAPA someone should be able to order one for you and stop over filling the tank I think this is part of the problem most times when they click off thats where you should stop and I think your problems will stop after you replace the can of course sorry to hear about the home stead how bad did you get hit ? :(
Title: Mileage update, 1,244 mi later...
Post by: Horst on October 12, 2004, 07:55:21 AM
yeah - I'm with Handyman on this one Andy - quit filling your Clipper to the hilt - leave a little room for expansion, etc.
And besides, you're getting 13+mpg, so you can stand to leave out a few gallons

Horst.... eat your heart out about mileage...  :)

As to the gas leak..... Al, I got the canister out (the idiots used a mile-long [rusted] bolt to clamp the thing.... AAARRRGGGHHHH).  Anyway... yeah, there are 3 different diameter nipples... one marked "carb bowl", another "fuel tank", and another "purge".   Btw... the canister is plastic, so my rusted-out theory went "kerplunk".   Interesting discovery however.  The "carb bowl" nipple was capped off, and the carb hose was hooked to the purge jobbie, and the line from the gas tank wasn't clamped - I'm guessing that's the leak.   Someone along the way just hooked it all up wrong - and I'll connect the hoses according to what it says on the canister.  When I replaced all my hoses, one at a time, I just connected them to exactly where they were before... you can't see the connection instructions at the nipples without removing the canister (which I obviously didn't do at that time).  I got a new canister filter while I was at it (Wicks #84998... $3.14), and as soon as it quits raining, I'll stick the thing back in, then go fill it to the brim again and see what happens.  The canister itself is Dodge #357759, for whatever that's worth - it's not available.  Btw, if anyone else does this.... watch it... or you'll have tiny charcoal granules ALL over!!!

I don't know if mine's right, but the "carb bowl" nipple was on the bottom, with the "purge" one top.  I have no idea whether the installation direction is important, or whether I should cap the Purge one or just leave it open..... any thoughts?

How badly did I get damaged?  My Loxahatchee place "only" lost all of the roofing shingles on the W side, which soaked the attic insulation and collapsed the bed and bathroom ceilings, trashing all the furniture, and most of the pool screening got ripped off - the pool's a mess.  Besides that, a lot of branches down, but all in all, not as bad as it could have been... or as bad as the folks right on the beach got hit.   However, Okeechobee is totally gone, nothing left standing except for 6 cypress trees.  "Hello... FEMA???"   Glad I have the Clip to hunker in though...  :D

Sorry about the house sounds pritty bad like the canister says 1 to the tank the other to the carb and cap off the purge   the purge was used on the lite weight sicx cyl and the 318 they had a purge valve your troubles should be over but still don't top off bad a on any modern car or truck because of the vaper cans   make sure to cap the purge port a peice of tubing and a screw will work :D

Post by: Andy Illes on October 17, 2004, 06:50:45 AM
Horst... the exhaust leak wasn't burned gaskets.... just loose bolts/studs, but I replaced the gaskets anyway since I already had them.  I was surprised how loose they were, I had expected a wrestling match!!!   If any of you do this (a fairly easy 1 hour job, btw - they're all easily accessible with the doghouse out), drain some antifreeze first.... the back studs (in the 360, at least) go into the water jackets, and WILL come out... and pee all over you while you're trying to work.  I'd also suggest using teflon paste putting 'em back in, btw.

Ummmm... what else?  Oh yeah.... my tranny fluid's down a quart, though I don't see any leaks (the tranny tail's damp, but no drip), and there's none in the radiator either.  I had the tranny serviced (filter, fluid) before the NY trip, so I assume it was full then (uh huh... in neutral, not park).  Any ideas why???   Btw, I only used 1 quart of oil on the entire round trip.... not bad.

Post by: Horst on October 17, 2004, 08:15:46 AM
Tranny fluid missing.....
Check your trans cooling lines  - sometimes they can leak, but it just smears along the lines and other parts near the radiator and trans and you don't really get a noticeable drip.

Most likely though -  the shop didn't put enough in........but that's probably better than too much........

Did you check the fluid right after the service (before you went on the trip)?
Title: teflon tape?
Post by: Conrad on October 17, 2004, 10:29:00 AM
Andy, I use an anti-sieze compound when re-inserting exhause manifold bolts.  I think teflon would not stand up to the heat.

Post by: Andy Illes on October 17, 2004, 04:05:07 PM
Horst and Conrad - thanks for the replies, guys.

ATF... the lines weren't the least bit wet anywhere.  Like I said, all I  noted was the tail end of the tranny's noticibly "damp", but no drips.  You're probably right that it just wasn't completely filled when I had it serviced... and yeah, I did look at the time and it seemed ok to me too, but whatever, huh?   Well, she's full now.... we'll see how it goes.

Teflon... regular Teflon paste's good to 310*F, which is plenty for heads, and Teflon boiler paste's good to 412*F, which is what I used.  Teflon tape can take even more.... 650*F.  Probably anything would work, thread sealer or whatever.... it just needs to be sealed.
