Hard to believe that I change timing chains, guides on my 97 4.6l just a little over two years ago. Pulled up to a light on the way home from work, and poor girl spit and sputtered then stalled.
Parked her, went and got a mech, found out he believes she jumped time......didn't change out tensioners last time around.
Got all the stuff ordered (O'Riellys was $133 cheaper than NAPA, and you can forget trying to find everything from Advance and AutoZone) gonna preform surgery on her Friday night.....this time using new tensioners as well.
Lesson: Don't forget the small stuff
Pulled codes after stall, read misfire on 2 and 3.

 

Just wanting to vent......Replaced timing chains and all the trimmings only to find out I have six bent valves, a bad water pump, bad PVC elbows....etc.....etc. We pulled the pass. side head and sent it to the shop for valves and to see if it can be salvaged......oh the humanity I still love my Ford but the dang thing is killing me.

 

Update, second weekend working on Ole Blue, found out a head job for my right bank would cost $$$, luckly found two heads and the guy gave them to me for $50 ( I dont think he knew what he had) Everything looked great on them, just had one bad valve spring. We cleaned them up (which they did nicely), changed the spring, and decided to check the the left bank head and camshaft out.
As it turned out the left had good valves but the bearing caps and camshaft cradle where marred up (had bad grooves worn into the aluminum), so we started on cleaning up the second good head. We got stalled because we had to order the left-bank head gasket and have it overnighted, so we put the right side head and new water pump on.
Hopefully today, God willing, we will put on the left bank head, timing-chain, valve-covers, and wire her back up and tighten her down.
I do think I got pretty lucky (so far) by getting 2 heads, 2 valve covers, 2 timing chains, tensioners, guides, arms, for $50, the waterpump was around $50, gaskets where around $200 (heads, valves, timing chain cover, and thermostat). I really hope this gets the old girl right.
Sorry if I am boring anyone but this is my first big project (big to me) and this stuff is really interesting, being I never really had to work on cars before.

 

Good luck

 

She is on the road and purring like a kitten, it took us about six hours (not continuous) of working and we had her buttoned up, fired her up and , I swear, she has never sounded better, an amazing thing occurred as well, we used EVERY bolt and nut !!!!
So now my Old Blue is sitting in the driveway instead of down at the garage. I also have two extra extra exhaust manifolds, valve cover, timing chain sets, and set of rockers. I wonder if I should keep them or see if I can dump them on E-Bay? Anyone have any suggestions?
Well I guess thats it thanks for hearing me ramble.
