This may be a stupid question but I have never been ask this question and I have always done them correctly but I have a 6.4l that just had heasdgasket replacement by another tech and my question is will the gaskets only fit one way or can they be installed with the numbers down.I have never yried to put them on any other way but this question has been ask to me from my service manager and I like to have 100% correct answer to give.

The ones I have done I heated the bolt heads with torch till they glow.Take air hammer with chisel end knock heads off.Hit them with penetrating oil and let them cool a while and they spin out easily with a reverse drill bit.

Thanks guys I will get back on this truck today and see what I can find.

I have a 97 7.3l i have been fighting for a couple days and i am looking for some input. Has 55psi fuel pressure.It is hard start as in it has to crank over 8-10 seconds before it starts.It will then run good when under light throttle but if you keep raising throttle or rev engine 3 or 4 times it starts cutting up and losing cylinders till it dies.It is then hard to start and will repeat same scenerio.It acts like it is getting combustion in the fuel rail but I have not been able to confirm that.It has no DTC's and fuel pressure stays constant 50-55psi during these episodes.It does tend to smoke somewhat when this occurs.

Has anyone seen a HPFP explode.It blew one of the heads off sheared the bolts and sent it through the cover.It then blew a hole in the rear.Warranty was denied by Ford.They have claimed water caused this.No engineer came out or anything.This truck had what looked like clean fuel and good filters.Bummer for the customer.

Tech that works beside me had one with this code today and this is what he found.Cavatation under the thermostat.I had never seen this.

Thanks guys I appreciate all the info.I think i am going to loosen the rocker bridge and put air in the cylinder to see if the valve comes up and seals off.

I contacted hotline on this truck so I would have some documentation of what items were recomended to be replaced being this is a customer pay job.Hotline suggested I replace all rocker assy on this one side and inspect push rods.No push rod damage but the cylinder is now low on compression.(200psi).With all valves closed the exhaust side rocker is still tight as if it is under pressure on cylinder #3.What will cause this.Lifter?.

When replacing all the rockers do you have to remove the fuel rail under the valve cover.If so Does turbo have to come off to replace the fuel line on back of head.

Okay guys I have searched forum as best I can and found no results.I have a 97 7.3l that has chaffed the fuel line under the turbo.I have always removed the turbo to replace these and it has been a while scince I replaced one but I am interested in knowing if it is possible to do without removing the turbo.If not any tips much appreciated.

My answer to "How Long" is "well if everything goes right it will be done between now and 5:00".

We have a new tech in our shop that just moved here to N.C.from New Hampshire this summer.He says most suspension and brake work takes twice as long to repair where he came from.He can't believe the difference in the amount of rust between there and here.He has an F150 and he had to break the rotors in half just to get them off his truck when he put new pads on it.Before he was done a brake line ruptured due to rust.It was they worst mess I had ever seen.I couldn't imagine going through that on a daily basis.

It has been several weeks since I put all 8 injectors in the truck.I got an update from the customer today and was told all is well.The engine has not shown any signs of oil use since the injector replacement.

Got the new injectors today.Lets put them in and see what happens.Hope it fixes this thing or customer just threw away some big bucks.It was his decision.

By the way I checked fuel in filter housing and it was clean fuel only.Turbo is slightly dusted but not bad.Tips are not rounded just shinny and a slight bit worn.We have the crankcase pressure tools but I figured if it had alot of blow by I would see signs of it where the crankcase vents into the air intake tube.It was missing the oil fill spout on the bottom that seals against the valve cover and no signs of oil vapor escaping there either.
