94 mustang cobra
 
Once again another prob..geesh! So now my battery light turned on and my volts dropped and dash lights dimmed. So I had the battery (interstate) tested and charged (passed). What else can this be?

dawson1112 07-01-2014 12:26 PM

alternator

Yep. Or voltage regulator (located on the altanator). Those are pretty much all the sexy parts on the charging system.

Js88lx 07-01-2014 03:56 PM

After I had the battery tested and charged I moved to the alternator. I had it tested at auto zone. 1st test failed, 2nd passed, 3rd passed, 4th failed, 5th failed. So I got a new one. Drove to work today and car ran fine..., but I don't think ive driven enough to really know. I hope I don't have a short somewhere.
I was also thinking about adding another ground to my motor. What you guys think?

bluebeastsrt 07-01-2014 05:59 PM

Id wait and see if you cured the problem with the new altanator.

Extra ground sounds like a waste of cash. 99.9% it was the alternator. My '93 Escort just pulled that exact trick (working, not, working, not) and its not unusual.

Js88lx 07-02-2014 04:54 PM

Ok. Well 2 days now and no problems. Knock on wood. Just that darn bbk header still not sealing to head.. head nod.

dawson1112 07-02-2014 06:13 PM

I had problems with my bbk headers not wanting to seal to my heads as well, I found that using the thicker aluminum gaskets worked.

Js88lx 07-03-2014 12:19 AM

Is there an easy way of finging out whether its leaking from the head to header or header to xpipe? Today i put the stock header back on and tick was gone... sounded soo dam# good! I miss not having an exhaust leak!

dawson1112 07-03-2014 01:36 AM

You should be able to look at the header that you took off, on the head side of the flange where it was leaking will be a carbon track. If they are on the car I usually just listen close to where the noise is coming from, and stick my fingers around there to see if I can feel any leaks. If you have some one cover the tail pipe it will usually cause the leak to become very pronounced.

Js88lx 07-03-2014 02:43 AM

ok kool. I just have to check later. I did put the bbk header back on but when i did have it off i tried looking for that carbon spot but couldnt see anything. Actually to tell you the truth i think just under the #7 port i could see what looked like burn or carbon on the head, i figured that was probably where my leak was. I wonder if a shop can re-surface the header?

Install a Percy's gasket.

Js88lx 07-03-2014 02:52 PM

These?

You could probably save 8 or 10 bucks by going with a summit racing aluminum or copper gasket. Metal gaskets hold up a little better than the usual cardboard crap.

Js88lx 07-03-2014 03:17 PM

OK.kool. But iv never had this problem before with other bbk headers iv had on all my other stangs., why would these give me such hassle? Iv always used mr gasket's and never had a problem.

Js88lx 07-03-2014 03:57 PM

I cant find the summit racing ones..?

dawson1112 07-03-2014 04:02 PM

Similar to the aluminum gaskets I was referring to. They are soft and thicker than standard gaskets. I went through two sets of cheap header gaskets and they always ended up leading after a few months. Once I installed the aluminum ones they sealed for good and never had a problem the rest of the time I had the car.

Don't F around over a couple of dollars. Percy's = win. I buy from summit since their support is legendary and unwavering.

I'd also toss the BBKs in the trash can, but that's a different rant for another time. :)

I kinda do want to get rid of them! What would you recommend? Nothing too expensive!! oh and carb legal if possible.., no biggie but would save me the swap every 2 years!

ok. but my header leak is instant! Right after I install them turn car on and give it gas and there it is... tick tick. At idle you cant even hear it.
