Hi everyone!
I have an '03 Jetta 1.9L TDi. I had a check engine light come on and found out it was the EGR valve. This past weekend I took it off to clean it up. The clean up went fine but, when I put everything back on, I noticed a bit of a whistle when I hit about 1800-2000 RPM. In doing a little research, it sounded like maybe I had an air leak around a bolt that needed tightening. I went in tonight to tighten them up and one of them on the top of the EGR valve (the 5mm one closest to the windshield) is just spinning. I had to go to the VW dealership to pick up another part tonight and asked the guy in the parts shop about it and he seemed to think I stripped the intake manifold when I put the bolt back in. Now, I didn't crank down super tight when I initially put the bolts in and, the bolt holds (I can't pull it out) and it backs out when I screw it out. It just won't tighten all the way up (I can still spin the washer under the bolt head by hand but not the bolt). So, does it sound like I stripped the intake manifold or is something else I'm missing.
IF the intake manifold is stripped, the guy at the VW shop said it would screw up my pressure and I'd probably get a check engine light. I don't have a light (yet?). Any serious side effects if I don't get this fixed? He said to get it fixed I'd have to pull the whole manifold and then use a helix coil to fix the threads.... I have about 15 piece tool set and that's all so... um... yeah.... that's going to suck....
And here I thought I was going to SAVE money by fixing my own EGR valve up.... Anyway, any help is greatly appreciated!!!
P.S. I forgot to mention that, when I took the bolts out, they had a blue coating on them.... was I supposed to put some sort of VW approved loctite on them before I put them back in? None of the info I found online mentioned that but, it wouldn't be the first time the internet has been wrong! :)
