Removing front valve color?

Do I have to remove the motor mount from the block in order to have clearance to remove the front valve cover? this looks like a big job, I've removed the ICM and coils packs. Help
 


the tentioner comes off with the bracket, make sure you put it back on right, and dont forget the ground wire when you put it back on.

not a hard job.
 


I'm removing to check my rocker assembly, do you see many failures, it's not noisey however It runs rough and smoother with #1 wire disconnected, have changed spark plug, wires, coil, ICM.
 
id do a compression test first then.

when this first happened was the plug damaged, like pieces missing from it or smashed looking?
 
No everything looked normal, while on a long trip started with a clicking noise put a little seafowm in the crank case quit making noise after a couple more hours of driving, have check engine flashing and running rough have checked all injectors, replaced wires and plugs 1/4 coil and Icm can't really hear any tapping noise.
 
If check engine light is flashing, you need to stop immediately!!!! Drive at your own risk of severe damage to the motor.
 


id still be doing compression test.

if a valve spring broke there would most likely be more than just a clicking noise. you'd hear the rocker clapping.

the flashing cel most of the time is one hell of a misfire or a clogged cat will also make it flash.

i second that... clogged cat made mine go nuts... flashing CEL like crazy... did the free misfire test to see if wires were arching, etc... (soapy water spray on the wires), wasnt the issue, took her to the dealer, and instantly knew it was the cat.
 
Took a compression test cyl #4 shows 25lb Tested it 5 times, 1 time out of 5 it went to 100lb, could this be a collapsed lifter? and still not be noisey, is there anything I can try to free the lifter?
 


pretty sure you need to take all the plugs out and then test the cylinders one by one, so to be able to compare your numbers.

at least thats how ive done it in the past.
 
Replaced the #4 intake push rod, runs great, I added rislone to the oil, I think I'll start it every few hours allowing the rislone to do it's job just in case my lifter caused the propblem. Any other suggestions appreciated.
