sounds like my exact problem, I am having my hg replaced within the next week. My compression was fine.

 

buMP IN THE forum, but none in the car!!!! How much should I pay for a h.g labor????? So Can someone that's familiar with the problem confirm my H.G FEARS!!! plzzzzzzzz

 

most likely the HG. and yes a HG can blow and still give good compression #'s

if the #4 plug is white and smells like coolant then it's probably blown around that cylinder

 

bump............is there any other logical explaination why the coolant would busting a hudini (disappearing)!!!!!!!!!!!!!!!1
