ea falcon turns over but wont startI replaced the head on my ea falcon and the spark plugs I went from NGK to Bosch and now the car wont start turns over beutifully though. I have checked the base timing and ignition timing both are spot on I have replaced the alternater and made sure all hoses and lines are correct my compressiion is very good on all cylinders have checked it both ways one plug at a time and all plugs out at one time

forgot to mention I do have plenty of spark it is a bit weak and a bluish orange not a straight blue like it should be

pull no one plug and check for tdc with compression then cheack cam and ignition timing again , I suspect you may have something out of timeing..
Real easy to do .

thanks for that I should have thought before to check TDC with plug out my harmonic balancer had slipped car is running now but is boiling hot within 10 minutes so now I have to figure that one out

The Harmonic Slipped?
Not possible, it has a keyway to lock onto.
More likely that you slipped a tooth or two on the timing Chain.
IF i am correct in what you have done (highly likely have done it myself ), then there are two ways to fix it.
Properly or patch it. (patching it will work if you haven't slipped too far)

Properly involves redoing the head, dropping the sump a little, pulling the harmonic, and timing cover.

Patch method.
Pull #1 plug, and set TDC from the hamonic. You should confirm TDC with a piece of welding wire down#1 plug hole.

Pull the rocker cover and see if the exhaust and inlet rockers are free (not under pressure). If they are not free, then you need to remove the timing sprocket and rotate the cam until they are.
This method IS NOT 100% reliable, as you can still be a tooth out.

When doing this, and any work where you unbolt the Cam sprocket it is IMPORTANT to keep tension on the chain at ALL times, as it is so easy to slip a tooth on the crank end.

Another thought (excuse me..had a few jars ) Have you run through the timing procedure????
Did you have to move the Dizzy much? In theory you should not have had to touch it, unless it was already out. If you had to move it a fair bit, it is a good indication that you slipped a tooth or some on the timing chain.

Timing WILL affect temperature.

If you didn't re-time the engine, find the procedure and check it....you may be surprised.

Hope this helps

if getting hot then you have the ignition retarded , advance it until the motor is hard to start ( once started it will hunt ) and then discover either the outer ring on the balancer is spun or the cam timing is out by a tooth or two .
on tdc the piston will be fully up and the cam lobes on no1 rocking and balanced across the lobes , then check the actual distributer timing , you do have a manual ?
the rotor will point out over the a/c pump and to the front a little
read the manual and good luck
