OK,

After a week or two I was periodically peeling a rib off the serpentine belt! WTF?? Seemed unpredictable. What I learned was amazing!
Did you know there are cheap serpentine belts and expensive ones? If you have a pulley even very slightly miss aligned the cheap belts can SQUEEEEEEEAL loudly! OMG!
Then they get shredded it is almost like they know they are at end of life! LOL! The expensive ones . . . .die slower and generally quieter!

NOTE: if you have a bad squeal from your serpentine system, take a squirt bottle with water and lightly squirt the ribbed side of the belt at each pulley. If the squeal goes away then comes right back you likely have a misaligned pulley and not bad bearings. Sometimes you can even isolate where the misalignment is by the noise!

Yesterday I think I finally resolved the issue. Starting at the crank pulley on the driver side, I have the crank pulley, an idler pulley, the power steering pump pulley, and the alternator pulley all on the driver side.
With a straight edge I could not get a straight line on all the pulleys because the idler pulley with no grooves was in the way. I had to remove it. Once out of the way, the other three pulleys were in clear view.
I immediately noticed the crank pulley had a wider lip than the other two and for me to hold a straight edge on the crank pulley would actually miss align the others! AH the lights come on in my head! I had to carefully hold the end of the straight edge next to the crank pulley but not on it. Instead hold it to the approximate thickness of the edges of the other two pulleys ( pump and alternator ) OMG! it was immediately obvious somebody was out of alignment!

After a bit of staring and studying, it was clear the power steering pump needed to be pressed in something like an eighth or sixteenth of an inch in! Using a special tool, it was easy access and easy to press in. I did it very slowly and checked every 1/2 turn until the straight edge aligned perfectly on all three pulleys! I then reinstalled the idler pulley and belt. I ran the motor for a bit at various RPMS and the belt stayed in place perfectly! SOOOooo, up the freeway I went for about 5 miles at freeway speeds and then took back roads home. The belt stayed perfectly in place with no squealing or pealing off a rib!!!!

What a relieve! I now feel confident I can drive her to an alignment shop!

Hope this helps the next guy!

Great explanation ...yes I know there are cheap & good belts...you pay for what you get usually. Last yr I had a very small pin hole leak in the upper radiator hose on the 73. After a 90 or so mile cruise the serpentine belt came off & I couldn't figure out why. Just enough anti freeze came out to cause the belt to become slippery & come off. The anti freeze that came out was so little that it disappeared almost immediately. I couldn't see the leak but my SIL who has eagle eye saw it.  These cars can be a challenge at times. Glad you finally solved this problem. Tongue

Yes sir and that issue was driving me nuts! Several times I thought "FIXED" only to drive a little further than the last run and lose the belt again!

I drove her in today with the vinyl hard top , spare belt, a socket, and a breaker bar! LOL!

This is her third run since the last fix described above and so far so good!

One of these days I'll be a knowledgeable back yard mechanic! LOL!

I know the feeling seems like everyone wants to challenge the 68 & 73 but hardly ever the 67 Dodge Wink. I have diffently mellowed over the years & rarely take anyone up on the off the line thing. Sometimes if I can take to them I ask what they have under the hood  if they have less than 500 hp I tell them it's not worth the gas & that usually pisses them off.

Are you "packing" when you say that?  Grin

When I had yellowjacket, I rarely got challenged. Probably because she looked and sounded nastier (hooker sidepipes) than she really was.

OK,
Next issue.

She refuse to warm start. Example, I jump in, fire her up and she starts immediately!
She drives with no issues. I go to a gas station. Stop and fuel her up. She wont start.
I wait thirty minutes and she starts without hesitation and runs great!

Warm Start:
1)She cranks very strong.
2)Fuel pressure 57.9
3)Air intake temp 120 degrees
4)Coolant temp 198 degrees
5)Can hear relays coming on with key on.
6)Fuel pump comes on if not already pressurized
7)Tack reads RPM when cranking

Note values are pulled via OBD blue tooth dongle and iPhone

Cold start:
1) Turn key and go! LOL!


I have already replaced the battery to one equivalent or better than a 2013 Z06 Cold cranking amps from Interstate battery.

I have used MAF cleaner to clean the sensor.

I have gone into the house grabbed some wine and sat in frustration . . . . LOL!


My next idea is to jack her up again and look for possible burned or pinched wires.

ANY ideas are welcome.

While I can drive her and she feels great I must plan when and where I shut her down!

Scott

Try a can of air cleaner ( it gets cold if you hold it on something) spray some sensors & see if cooling them down detects a bad one.  Spray the distributor & coil too. Also pull your plugs (look and see if they are wet) to check that you don't have a leaking fuel injector which would flood your engine. Remember if it's getting spark it's almost gotta be a fuel /air mixture problem. Check to see that you are getting 12+ volts everywhere (the ignition areas)

Good luck

Buy a brand new trouble free Corvette?

Drive sharky to work, then home after work... and as a dinner car. Take time eating, go get in sharky and drive her home... end of problem.



Just tying to lighten the mood... been there done that many times with yellowjacket.


BTW, Can you give me the brand of what your using for that OBD bluetooth dongle and iPhone? And what you think of it?

LOL! I'm with ya Jack!

I was going to drive her in today and get the dongle part number for you but it was raining so I do not have it handy yet.

The software I have been using is called "Auto Doctor".
It is rather difficult to use on an iPhone while driving but does read my "bad check sum" computer. Other cooler software packages would not.

IF you decide to buy a dongle, remember blue tooth works best with iPad and wifi for androids per what I have read. Also the dongle must be capable of turning itself off when not used. Otherwise it will drain your battery if you leave it in the car and plugged in.

I'll probably get the OBD dongle you have and same software as your familiar with it. I have three cars so will it work with all of them, or just the one car? I don't plan to keep it plugged in but just to check now and then and especially if the engine light comes on which it does all the time with the 2000 Ford ranger I have. Which software version of "
Auto Doctor
" you have? The "
Express
" or "
Standard
".

Before contacting you, I was checking out this OBD
https://scanneranswers.com/foseal-wifi-obdii-scanner-review-2016/
and this software.
https://itunes.apple.com/us/app/obd-fusion/id650684932
Last question, I was reading where some of them can even give you a estimated HP?

Oh yeah I finally after 15 years of android phones switched to iPhone this year. Only because it was buy one get one free from T-Mobile... wifey won that one as she has always had a iPhone. Me, I still like the Samsung Android phones  Sad
