RS Disposal

So far it looks like the head is no longer available (still looking though).  Pistons and the associated rings, valves etc. are.  Guess I need to pull the head and actually access the damage.  Quick question, is there a trick to getting the exhaust manifold nuts off?  Would it be a problem heating up the nuts?

I'd bet your head is fine, and piston may have a tiny dent in it that needs to be deburred.  When you take the head off, DONT set it down right side up, you will crush the injector nozzles! You will probably just need the one valve, maybe the guide,  and maybe a valve seat? 

I am keeping my fingers crossed as to what extent of damage there is.  Im just trying to source parts for a worse case scenario just in case.  Looks like I need to go to the dealer and see if he can give me some part numbers.  Nobody seems to be able to pull up anything on the truck from the VIN, which in the past with other parts the dealer has had no problem finding the trk thjru the VIN

Minimal chance of interference.. would be my guess.  Is the valve bent or possibly gummed up?  Just being hopeful here.

pretty sure bent.  When I grab onto it with a pair of pliers it doesn't move at all

Sounds like a bent valve then. If you're lucky you just need a valve, don't need a head.

Pulled second rocker cover.  everything there appears to be fine.  I can twist the pushrods no problem.  How much of a possibilty is it that I am going to actually need a head and a possible piston.  Obviously I have one bent valve, but with light truck gasoline engines (I'm a light truck/automotive mechanic) subject to valve float/bent valve I have seen ones that didn't crack the piston

I know the head gaskets are,   (20 Bolt heads)

 

I bet the others are too..  

My heads are 18 bolt

Probably just a bent pushrod from valve float.

I have pulled one roccker cover and #4 exhaust valve is stuck down (assuming bent).  Push rod appears to be ok.  The valve spring keeper was broken.

I think all parts, possibly including the head are still available

Thats what I am hoping.  I can do most of the work that needs done on the truck except engine work, hench why the head hasn't been pulled as of yet.  Don't really want to have it towed to a shop and have them tear it apart only to tell me parts are no longer available.

I haven't pulled the head(s) as of yet.  Wanting to see if parts are available before I start spending money on an engine with no hope of repair

My mechanic tells me that most likely I will be needing a head and possible piston/valves for my trk.  It was inadvertently started with throttle wide open and now have a stuck exhaust valve on #4.  Engine model  # ENDTB 675
