That is strange what happened to that head. Just figured i would bring that up for future endeavors. The worst part is, if the leak is huge, and it doest work, your only out 5 bucks and you end up replacing the head and or gasket anyways. After having the car forever, i sold it so someone who never knew about the gasket leak. the stuff is supposed to be a permanent fix. So i said ok why not.After i put in a new radiator, and filled it, i put the stuff in exactly as the directions said. ended up blowing the head gasket in my overhead cam 4.6 ford. My X-wife stabbed the radiator in my car and then drove it down the highway. Go to a local parts store and pick up liquid block. If i had noticed this thread before i would have told you to do this: I'm sure he'll decide this week if he wants a local shop to fix it or if he's ordering a rebuilt head from somewhere. Not sure what my neighbor wants to do yet. Barely enough to weld, but that's the way to build it back up. It isn't deep near the combustion chamber, but the last 1/4 inch near the coolant passage is probably. I don't think that 10 or even 20 thousandths would do it. Ok here's a link to the photos of the head (I hope). OTHER than obviously blowing one with a turbo or something. You're the first person I have heard have a head gasket problem on a 4.7 Upload the pictures there then copy and plaste the URL in here. Not sure that's even possible for this motor. My neighbor's trying to do this as cheap as possible. This thing needs to be welded up or replaced with a rebuilt head. Wish I could attach a photo to this thread to show everyone. Looks like a small ant trail wiggling from the coolant passage to the #2 combustion chamber. The problem is corrosion on the head between the #2and 4 combustion chambers. I've got this thing entirely pulled apart. Sorry I couldn't resist the sarcasm, can you tell how happy I was with thier manual? If you read a Haynes manual for R&Ring the heads, it will have you removing the rear tires, headlights and oil pan, but not mention you need to take off the valve covers. Those wedges are along the lines of what I was thinking though. So are we talking radiator shroud/water pump/harmonic balancer, or does the WP come off with the cover? Is there an upper front cover and a lower cover with the balancer? I just have the top of the motor apart so far - Guess that the best way is to just dig into the front, too. I realize that a Chilton/Haynes might answer this for me but I haven't bought one yet. Unless you can think of a way to keep the chain from getting slack as you do it ? If the chain goes slack, the adjuster takes up the slack, and you have to dismantle the front to reset it. I don't think so - the cam chains have automatic tensioners that will take up slack - that's why we use wedges when swapping 4.7 cams. Might be a recipe for disaster for the installation, though. It was better than nothing, but severly lacking on information if your used to Chilton manuals.Īny chance these heads will come off without taking the front of the motor apart? Can I just unbolt the cam gears and the guides from the heads, then slide the heads up and over the cam gears/chains/guides? Seems like this would save several hours of work over disassembling the front of the motor. The Hanes manual was a total POS, told me to remove things that didn't need to be removed and missed other things. I bought a Hanes manual (only thing I could find on short notice) for my 03 Dak while dropping the tranny. There is no water in the intake manifold so no way it is coming from there.Īs far as I know, there is no head gasket issue on the 4.7's.ĭo yourself a favor and buy a Chilton manual for the truck. He (my neighbor) just changed the plugs - I haven't looked at the old ones yet. He's got the excessive white exhaust and low coolant level. Is this (head gasket leak) common for the 4.7? Or is there any way for the burning coolant to be an intake manifold port leak or something else? Just trying to diagnose this before pulling it apart. Do the cams have to come out for access to the head bolts? Head bolts must be replaced? Anything else to change/fix while I'm in there? Thanks for the info,Ĭouple of questions. I will definitely get a book that covers the steps - I don't want to wing it and mess it up. The head gaskets are multi layer metal and come off pretty easy as well. The intake and valve covers come off easy and those gaskets are reusable. You WILL have to pull the timing chain covers and remove the secondary chains to each head. RE: Any tips -changing head gaskets on 4.7 I still have to check into buying a manual or checking online for any specs and/or procedures. Any tips on this job? Any special tools? I just did the heads on my 5.9 Durango so I'm hoping it's not much different. My neighbors 2000 (4.7) with 140k miles just started sputtering and then blowing white smoke.
