HI, I recently discovered a minor coolant leak comming from my engine compartment, though i couldnt pinpoint the location tried some, "Bars stop leak" seemed to work fine.One morning comming home from work I had to pull over 'cause the intake gasket blew. I replaced the gasket and now she dont idle worth a damn. Now when its idle ing it almost sounds like theres a potatoe in the tail pipe "no theres no potatoe in the tail pipe" Like its under load, i changed the fuel filter used carb cleaner, flushed a crapload of that bars sludge out of the resevoir, This **** should be illegal, natta. I didnt run it long enough for the temp to raise either. Please help me it taking over my world.
OH yah, its an 85 12a w/k&n and 2.5' exaust.

 

Hey i put sum stop leak in my coolent system in another vehicle i own and have to have radiator removed and dismantled and commercially cleaned was 70% blocked with that ****. was taking over my world too. he he is worth a look cost me round $150 new zealand dollars

Thanks mark

 

This will get more answers in the first gen section...

 

If a moderator would please put this in the 1st gen section, he might get a little more help from people in that forum area.
I had a 1980 12a, but I sold it 2 plus years ago so I can't remember a damn thing, sorry but I'm sure some of the guys in the 1st gen section can steer you in the right direction.

Get some carb spray and spray it around the intake to make sure you don't have a vaccum leak. Your probably only running on one rotor because of a leak. Easiest way to tell is to start it up and give it a little gas and see if it climbs smoothly. If not, Check for leaks as stated and try again.

Just so you know, I've had this leak before and it will cause you to run crappy, Sometimes only on one rotor with the occasional runs good then runs crappy scenario. Cause was from a stripped out intake bolt.

 

Yeah, what he ^ said! If the problem started when you replaced the intake gasket, then that's the place to start.

If there is no vacuum leak, then verify your leading ignition is still working.

 

Thanks guys I'll give it a go today.

 

Yeah, vacuum leaks will do this. Also look into your thermo wax, which will control idle.

 

Okay, I tried the carb cleaner thing, no change.
I swapped coil leads no change.

I thought maybe a little run would help, so I took it around the block and the bitch boils over, doesnt even show regular operating temp. Now I'm getting my gear ready to climb the water tower, if you know what I mean.

 

hmmm I'm guessing your radiator is blocked up with that junk you put in. Thats why its boiling over cold.
My guiess is the clogged radiator has now caused a bigger problem and you are probably getting coolant shot into the combustion chamber.

1. Did you blow smoke on the ride around the block?
2. Change your oil and see if there is water&anitfreez in it. Or just check your plugs ans see if they have goop on them.

I'm not sure but I think you probably cracked a coolant passage. After you check the plugs or oil we can be sure.

What ever you do don't run it again with that crap in there. I would suggest a bit of junkyard surfing to get a new radiator and get the rest of the system flushed then you have to fix the problem. Oh yeah and its likely that crap clogged your thermostat . You really need a new one of those.

 

Oil is fine,no "milk"
The plugs a dark tan colour, dry, no goop.
Drained the cooling system removed one of the heater hoses from the fire wall with the garden hose in the rad water flowed freely,( I pulled the thermostat prior just to rule it out) Pulled the drain plug under the spark plug and no prob.the i removed the bottom rad hose no problem. After all this I ran it around the block, not taking any chances.
Ive downloaded the instructions on how to remove the rats nest, that should narrow the idle issue down, shouldnt it? As for the over heating .......
Oh well plenty of time for sleep when Im dead.

 

How long does it run before overheating? I have heard that water pumps can fall apart (I'm assuming you would have noticed if the belt was off or loose) and stop working. If water is flowing freely as stated above, then I would look here next. Good luck.

Also, have you actually verified that you are getting spark to your lead plugs?

 

I found the culprit, a hose came off the back of the carb that attaches to the intake manifold, hard one to find. Thanks for all the help.

 

Wow, a hose on the back of the carb that was making your radiator overflow? Can one of the experts explain this one to me? Now I'm curious!

Congrats on finding the issue!!!

 

I dunno about that O_O

If a disconnected hose can make your rad overfill, than I'm SURE mine would have overfilled when the only hoses I had connected to my carb were the fuel hoses (I so kid you not. . . . didn't have anything blocked either. How much I have learned!)
