ok so just did the head gasket on the vr and got it all back together and now it is missing like timing is off

but i have torn it down and cheaked and its good from what i can tell with the cam shaft timing tool

the only thing i can come up with is the camshaft positioning sensor is bad because when i unplug it the car runs the same with a miss
i am ready to kill this thing i have torn it down to the cam chains 3 times to make sure it was timed right

if anybody has any insight on where i should go from here i would greatly appreciate the advice

I have tomorrow evening off. We can hook up a VAG COM and I can scan it to see what it's doing.

Dan....

You used the cam alignment tool, right?

Looks like this:

Like Matt said, check the coilpack. If it has even the slightest hairline cracks in it, it will misfire like a son-of-a-bitch. swap out the coilpack with your extra pack, and clean the old one off real good with brake cleaner and paper towels. You will see the cracks, if they are there. High heat epoxy from Home Depot, or Advance Auto will fix it... just make sure to cover the cracks with a healthy coating of epoxy after the CP is completely dry. Be sure to cover the seems, around the base of the terminal boots as well.

I used a 2 part epoxy gel that was rated as high for heat, but it did not run all over the place like traditional epoxy that I have used before. I just recently repaired 2 coilpacks with good results, and had a repaired CP in my mkIII for 30K miles, before it was rearended.

Some of the pictures did not open here, and this is the worst case of a bad coilpack that was repaired I have seen, but you get the idea:

http://www.rocketcat.info/blog/2006/05/howto-vr6-coilpack-repair-step-by-step.html

Apparently dude had no problem after everything went back together.

Same thing, as far as cracking, goes for the cam position sensor. If it is cracked, it is bad, and I have not heard of epoxy fixing that fucker.

I will say this. My brother did his head gasket, and noticed afterwards the car did not run as strong. no misfire, but something was off.... Turned out, the cam position sensor had a small crack in it.

Good luck man!

so i work tomorrow night so that will not work chris but thanks i work every night till 12:30 but fri. and sat.
yes i did use the same alignment tool i picked one up from ecs when i did the timing chains
now that you say that i remember a port on the coil were one of the wires goes is broke and missing part of a lip
so when i get up in the morning i will switch the coil packs and clean the old one and see if it is even repairable
thanks guys i will try the other pack and if that one is bad i will try the epoxy trick on the best one

Smokestack · « **Reply #6 on:** September 14, 2010, 09:34:59 PM »

I don't work till 5 on Friday, so I can probably swing by in the morning. Let me know when you want me over.

MrGhia · « **Reply #7 on:** September 15, 2010, 12:37:58 AM »

sounds good man i will let you now how it goes in thew morning
i pulled the coil pack off just now when i got home and yep i see two or three bad cracks and a few hair line ones as well and all most half of the #2 port is missing

so thats hopefully it
amazingly my ex coil pack looks good no cracks at all from what i can see will put it on in the morning and hope for the best

scurvy_bandit · « **Reply #14 on:** September 17, 2010, 03:03:15 PM »

any VR's in the junkyard?

MrGhia · « **Reply #15 on:** September 17, 2010, 04:10:07 PM »

nope me and chris went to all of the ones that would have had them
u pull and pay has the mrk 3 still but no one has the mrk 4 stile

LOS · « **Reply #16 on:** September 17, 2010, 05:28:26 PM »

I may have a spare set but I can't get to them right now. Gonna be about 2 weeks as in shipping out for my honeymoon

Smokestack · « **Reply #17 on:** September 17, 2010, 08:59:51 PM »

This stupid car reaffirms my dislike of mk4s. VW used special, short injectors with air shrouds in place of the standard bosch injectors, and they're only found on the 12v's.

Thankfully it sounds like Dan found some.

MrGhia · « **Reply #18 on:** September 17, 2010, 10:41:38 PM »

yep got some thanks to brandon

will put them in in the morning

MrGhia · « **Reply #19 on:** September 28, 2010, 07:47:16 PM »

i give up on this peice of crap

i hate this car !!!!!!!!!!
just stoped running yesterday at a stop light with my wife driving so i got that call "its not running and its all your falt" so i came down and looked at it thinking over heating but no its fine on temp
so i drove it yesterday with out any problums but today drove it agian and just died when i got to a stop light and would not fire agian for a few min. it was like the car was not getting and spark but then just fired right up after a few cycles of the key
then later that day did it agin at a light and would not start for nothin for like 4 to 5 min then just starts but this time when it starts it sounds like it has no oil and lots of valve noise but dip stick said just fine on oil but i put some more in and then the vavle noise went away
i hate hate this fucking car and unless i find out what is wrong it is getting a hammer to the motor because im fucking done

LOS · « **Reply #20 on:** September 29, 2010, 05:08:21 PM »

Might be the coil packs going out or shot. The no oil noise and running rough sounds like the coilpacks.

The Asshole · « **Reply #21 on:** September 29, 2010, 09:25:10 PM »

this whole thread says coil packs every other post....have you replaced them?

MrGhia · « **Reply #22 on:** September 29, 2010, 11:57:07 PM »

yep and no its not the coil pack
i think it may be overheating i was able to get it to die on me at home after i replaced the coil pack and it seems only one of my fans is running will tar into it tomorrow and test them

Barry · « **Reply #23 on:** September 30, 2010, 05:34:17 AM »

check the temp sending units, located in the water neck too. If the mkIV is like the mkII, then the sensor that controls the fans is in the radiator.

also, check the after run pump.... who knows... you could have a bad water pump too.

good luck!

MrGhia · « **Reply #24 on:** September 30, 2010, 01:19:15 PM »

looks like fans so did as the bentley service manual said
tested the fans at the thermo switch and tested the first speed and the right fan comes on but not the left and tested the vaults going to it and its getting power
when testing 2nd speed neither fan comes on no power to either of them witch means the Auxiliary Fan Control Unit is toast as well

so if anyone has fans or control unit
let me know please and thanks
looks like mr 3 used the same Auxiliary Fan Control Unit
but different fans

LOS · « **Reply #25 on:** September 30, 2010, 04:18:40 PM »

Sucks man, go to the junkyard, best foreign will probably have that.

Barry · « **Reply #26 on:** September 30, 2010, 08:16:50 PM »

yup... best foreign.... I think it was $100 for both fans in the shroud....

MrGhia · « **Reply #27 on:** September 30, 2010, 11:41:15 PM »

ya i think im going to go get the Auxiliary Fan Control Unit first and see if i need just the left fan or if i need both
anyone been down to u pull and pay and seen that 2000 jetta down there did it still have the motor in tack or is it well picked over

brandonb85 · « **Reply #28 on:** October 01, 2010, 10:19:57 AM »

I have a fan assembly I had Barry pull for me

I pd 100 you can have it for the same

MrGhia · « **Reply #29 on:** October 01, 2010, 09:13:02 PM »

is that both fans?

brandonb85 · « **Reply #30 on:** October 01, 2010, 09:14:51 PM »
