Low compression??
I did my head studs and a couple of "delete" things to my '05 back in March. I had the heads surfaced and several valve guides replaced. I've put approx 2,000 miles on it and now when I crank it, it sounds like it has low compression on one cylinder.
When it spins over, about every 2 seconds it sounds like the starter hits a "weak" spot....like one cylinder has low compression. It does'nt take long to crank so it's hard to catch it. Once it cranks it runs perfect....no miss or skip.
My local Ford Dealer says he can hear it, but has no clue what it is. One tech said a valve guide is wore, and once it starts the valve "centers up"...whatever that means, and closes up the compression leak.
It now has 45K miles on it. I did the stud job because of pushing coolant from the bottle. The heads were warped badly. Now I have NO coolant issues. All is good except for this sound when starting.
Should I ignore it or what??? Thanks for the info in advance.
