I've searched some of the numerous posts on the intake and coolant issues.
Here'* my situation - any comments welcome, but if everyone'* sick of this subject I'll understand. There'* so much consternation on this subject, my head is spinning. Thanks, as usual, for any input. This forum - well - as many have said before me: man, it'* great.
1999 Bonneville SE
Total miles: 102K (total on new motor: 10K)
I had complete engine failure due to intake failure, and I had to get a new motor. In fact, I opted for a brand new 3800. In retrospect, I wish I had gotten a Dorman intake, but I was just learning about this whole problem. Anyway, I got a new GM intake at the time.
Now, since the new motor I have been using Yellow, instead of the DEX. I think I now have a 180 T-stat as well.
I have 10K on my new motor - so far so good. But I've been thinking that I should get a Dorman soon - even with this low milage - because I'm afraid that the intake will fail again, even with Yellow. My mecahnic says he feels that the DEX is really the culprit. I sez to him, I sez, "Sez you! Maybe it'll fail again with the yellow too."
I'm not equppied with the tools and proper know-how at this point to do it myself, what with goofing around with the fuel rail up there, and I don't know what-all. He'* quoted me about five bills parts and labor to change 'em out
This is a really great shop (they changed my motor too,) but yikes!
Or, I could have the intake checked for half that money, but that somehow does not seem worthwhile.
What do you
Should the intake be changed?
Leave well enough alone?
Will it probably be OK since I am using Yellow?
