Got a question that I should know the answer to....but don't and can't find it anywhere with searches... Will 3v heads bolt on a 2v shortblock assuming you don't care about the VCT? If so would you need all the 3v chains and guides or did they keep the sprocket size the same?
#6062
it will. mine was hitting the shaft so i unbolted it and pulled it out of the way. now that the motor is sitting down in the car the shaft clears it. plus ill get about another inch to an inch and a half when the motor mount stud sits in the proper spot
#6065
Is it turning over but not starting? or not turning over at all? Double check that every thing is hooked up, and give it alittle gas(pedal-wise) when you're turning it over, mine was a bitch like that for awhile.

Hey guys, quick question. I am not getting oil pressure reading.
I put a new oil pump on the 5.4 when I installed it. ONe other thing I did was put the 4.6 oil filter and lower radiator hose assmembly with sensor on the 5.4. Should I have left the 5.4 assembly on it? WOuld that have anything to do with it? Possibly a port to the sensor not mating up?

where do you manually check oil pressure at on this motor? Can you think of anything I may have done during the swap to actually cause this problem? Or would you think it is a false issue?
I am not getting any codes or lights for oil pressure low, or sensor not working

Other than attaching a mechanical oil pressure gauge to the stock location, I dont know of any means of checking oil pressure. The stock sensor is just a pressure switch, when it drops below 6psi, the switch closes and the MIL light comes on. You should be reading in the neighborhood of 90 psi cold, and 25-30 psi hot at idle. If you are truly not getting any oil pressure, I woluld not run the engine as you will toast the bearings.

The sensor might of been broken in the swap ($10). I suppose you could buy a manual gauge but for a quick way you could pop the sending unit or filter off and crank it over without starting it. Wont exactly be accurate but you would atleast know if you've got oil that far. I dont really think it will throw a code, I think its really just the sending unit and the gauge, atleast on my car but its a '97

wish i could help on the oil pressure problem but thats something i dont know much about.
i have a quick ?. im getting ready to start buying all the peices to do my swap. im gonna buy a new navi shortblock and timing cover. will my chains off my 4.6 work on the 5.4. will my tensioners fit? i know my secondary chains and tensioners will bc the have nothing to do with anything besides the head.

IIRC, the primary chains are all the same on 5.4 regardless of SOHC or DOHC, that is why the DOHC's got a secondary chain arrangement.

Glad to hear it. Seems like we all run into little issues, some bigger than others.
#6084
The one in the valley is the knock sensor, the other is the cylinder head temp sensor. My car didnt have them either, Cobra's were the only ones with knock sensors.

okay, do we have the plug on the wire harness that goes to them or no?
#6088
CONGRATS !!!
What was the problem with the oil pressure ... ???
Also ... what were the little problems that you repaired that kept it from starting for so long?
PM me you contact number please. It looks like I may finally have some time this weekend.
#6090
Joey what year is your block? this interests me bc i have a cobra and might want to reuse my knock sensor. but cobras have two knock sensors one on each side of the valley.
also does anyone know how big the hole for the know sensor is on the 5.4? i need it to be 3/8"
