I can at a pretty penny..the 5.4 isnt a drop in deal and more than id want to deal with..and yes they definitely are cursed!!Can you find new heads? Will Boomin's motor drop in? Might be cheaper to call those heads cursed and move on.
It seems that way but then again this is the main style of heads everyone runs on the big 1,000+ mod motor builds and definitely dont hear about them having problem after problemI'm in as much disbelief as you are. That style of head must be very difficult to work with. It makes no sense.
Its disabled. .its gotta be guide related. .just dont understand how it didnt smoke when they wore completely out last timeI have no clue about what the smoke related to the heads could be. But what's the chance that the EGR system is somehow flowing too much and at the wrong time? Did you disable that or is it still functioning?
No the bottom end got rebuilt and ran with the heads from this shop for over 500 miles,never smoked a bit till i lost compression. .the guides totally wore out,why it didnt smoke then idkummm... Just wondering.. I remember hearing a story of someone who rebuilt their motor and put the rings on upside down so that all of the oil got forced into the cylinder instead of wiped down the skirt and that it smoked like crazy....
Any change that a ring got put in wrong somewhere or there is a seized up ring ?
I run a separator. .intake has always been bone dry..the valves previous had signs of oil leaking on them..i obviously haven't had these back off to look,just got them on sunday night..hmmm.... Well where else can oil get in ?
PCV. Is the vent good ? IS the pipe/hose full of oil by chance?
Did you check compression again with the heads freshly redone?
ummmm...???
Yep..probably going to find a used set of "DC" cast heads and throw them on..How's the Aviator doing, still smoking?
I agree!! The DC cast I've never seen drop a seat or read about,Ron said same and said hardened seats, or SS valves really wont be needed till like 30lbs..i plan around 18 soooWhatever the cost is, its cheap compared to what you have been going thru.
Once the valves and seats are assessed, you might just be getting some new stuff there also.
You just need this problem to go away.
