357ford Well actually it isn't but we don't have smog testing...I just hate to get into it again...I spent some time getting the timing set up using timed vacuum, think I carried a 1/2" wrench and an allen wrench with me for a month......ah, its been a while...time to do something different. That second picture looks good as well, 67 for the nova was a good year.

batman09 thats correct.the mechanical advance is already built into the can change it if you want(different springs)I left mine alone and its fine.The car has so much more power with the manifold vacuum vs the ported vacuum.If your vehicle is smog exempt,I highly recommend manifold vacuum!here's another pic

That is one nice nova.

So all you have done is set initial at 8 and adjust rpm of idle and run manifold vacuum to the vac canister with no modificaton of vac advance or mechanical settings?

Doc here

Good News! I thought the 8 degrees would get you set up!

Glad to hear your Gold...

Nice lookin' Ride.....

357ford I think the "foot across puddle" comment threw me as well.

Any vehicle as mentioned is proned to spew a little thin white vapor/spit some water out the tail pipe, with humidity changes.

If you mix your antifreeze as recommended, that "puddle" would have a noticable sweet smell, if it were a faulty gasket.

Your probably in good shape.

5.0 freak could be your gas, if you get wattered down gas it will spit out your exhaust. Try getting gas from a place like chevron or who ever it is in your area that sells the "Better" gas.

batman09 yeah thats it.The puddle is more like a run...its about 1/16-1/8" deep by 1 foot... kind of a spray.I guess puddle was the wrong word.It was idleing a long time as I was setting the timing.I will run it tomorrow when I get home from work and tell you guys more.Thanks bm

Old School Nut i have had puddles that big under my tail pipe when i start up my 66 early inthe morning... it normaly dont do it but every once and awhile i get a bunch. the puddle tho is more of a run (1/2 inch to an inch by a foot) if the puddle is like this i would say its fine.

Doc here

I can't see that much change in water in a mild change of timing ... although.....ya never know...

Run it...Idle is one thing, driveabilty is another ...observe everything it does...If it don't heat up, doesn't detonate, boil over or run doggie... than it's all good...Long idles Do build up water...

Doc here


I agree with you fully on the normal byproduct of combustion, and since I live about 25 miles east of Batman, I can attest to the fact the temperatures have soured the last 7 days here. triple digits with low humidity....where it's usually 68-75 normally..

But unless he's exaggerating a bit on the foot across puddle on each pipe, That seems a lot to be just normal condensation, unless he's got both muffler's Full of water.....

On normal condensation days here, I get a usual puddle under the pipes about the size of a silver dollar...and mild white clouds until it warms up. but never foot wide puddles..

My Vote's For a gasket somewhere gone south..

batman09 Doc,
I'm sorry....this is not a new motor,the car is new to me.
I will answer your questions in order.
1.the motor is a 94 gm crate motor with 25,000 miles on it.
2.I had a temp problem for a while,it overheated twice
3.The oil is clean.nothing abnormal at all runs good,it idles alittle high..900 rpm starts right up
6.the fluid level stays the same.doesn't boil over
7.No white puffy smoke at all..never

I appreciate your thoughts and anyone else who wants to chime in.thanks bm

There was a huge temperature change today.Its been baking here for the last 5 days(90-96 degrees) and today it was 70 degrees.Something else I forgot to mention.....I just got 2 new flowmaster 40 series put on yesterday.I had the dynomax turbos.They were rotten.This probably doesn't have anything to do with my problem.Thought I should mention it though. bm

jimfulco Water is a normal by-product of combustion. If you are spending a good bit of time idling, it may be condensing in your exhaust system & spilling out the tailpipes. Kinda like Grandma's old 455 Bonneville did because she never pressed the gas pedal more than 1/8" down.

Taste a fresh drop of the water. If it's sweet, spit it out, it's coolant. If not, it's probably just condensation.
