Default Great Write Up!!!!!!

This is fantastic. I want to get this done this spring. I have a question.. starting up the engine when the job is complete, I see that some guys have had the timing jump on this something I, or we, should be concerned with?..Sorry for all the questions I just want to make sure I do this right...I don't know if the problem is if the engine is under compression or if it is something else...thanks...and again fantastic write up..Cheers..Spike24

That was a fantastic write up. I'm about to do the same exact thing I do have excess chain slack and do Have a tick.and some chain slap sometimes at startup .. not injectors full warm .. I believe that's what's causing the issue with this motor. Its a very good design. And will last but the basic public doesn't have the knowledg..that we motor heads have. And ford. $$$$$ doesnt want anyone to figire it out.U should write this article up and sell it lmao

Hey guys.

I will try to best answer your questions from my blackberry here.
You don't have to remove the engine. After removing fan, power steering pump, and other small crap in the way, there is enough room to work.
AC does have to be decharged.

As for timing chain slack. With new tight chains, it should not be able to jump. Only when the chain is worn badly.
Even at that there are 2 good practices
1. Always turn engine over by hand a few fell revolutions to ensure there is no piston to valve contact (just use a socket and ratchet)
2. Remove pcm fuse and crank engine for 10 seconds before attempting to start to build some initial oil pressure.

Great write up! My question is how you know if a lash adjuster or roller follower is bad. Ive never seen a good one or a bad one. Is it really obvious or do I need a micrometer? What should I look for?

This is great, my buddy has 140k on his and a horrible tick, but im at 80k and only a light tick. And i would die if mine sounded like his hahah.
Anyways , im very handy with just abt any tool u show me but would you have any advice for me for learning what each part and its components does and how it functions before i jump into this and make a costly mistake? Thanks!

Cam followers/rockers just look for wear on them. The only real way to check them is to remove them with the tool and turn the roller portion and check the bearing.

The lash adjuster is harder, you can check to see if any bleed down after the motor sits for a while.

When in doubt and its open, replace them.
