this is a new one it seems.....

with the great weather and a little spare time, I finally took a minute to tear into the jetta.  Took off the head to do a head gasket, and also to see if there was any catastrophic damage to the #3 cylinder, which wasn't firing it seemed.  It was the only cylinder that wouldn't drop the rpm's after loosening the hard line nut, and I was expecting the worst. Well, the cylinder looked fine, but found a lot of carbon/crud in the combustion chamber.  I also found a nice little crack underneath the #2 cylinder precup.  That cylinder was firing fine.  I realize a new/different head is on the shopping list, but what would cause the crack?  Can't say I've really seen it happen often.  I'll try to get a pic, but I don't have a camera right now.  Gonna slap the head back on tonight and see if I can get this little sucker to run again.  If it runs the same as before, I guess I'll do a compression check first, then go from there.....

Oh, nice car!  Just poking in as project direction has changed.  I now have a rebuilt head for sale if interested.  Only the orig. casting was used.  PM me.

Your car brings back memories. I had an 84 in the exact same color. Along with a Rabbit pickup and a 2 door 82 Jetta coupe prior to the 84.

Before the internet and this site.......

 Good luck with it,.

Stay safe, stay well. Jimmy

all good......for whatever reason.....one injector, a head gasket, four hours labor, and seven months later, she revved to life right on the first try after bleeding and running like a champ......  Still gonna need a new head though

me and my 130 pounds torquing a head gasket....
