Ticking Noise After PI Swap

mct96gt · January 15th, 2012, 10:58 PM

After finishing my PI swap the motor is making a really bad ticking noise on startup that continues til the car warms up really good and has been running for a while. Its a steady constant tick that will go away after some amount of time unless the motor is in a certain power band under load then it never really goes away. When I did the swap I put in new lash adjusters in the head and was thinking that maybe this could be the culprit. The only other thing that I could think of is that I also got a new timing set and put new tensioners, guides, chains and gears on it when I did it. The new tensioners were not the same as my '96 but the instructions said they were just an improved design and would work just the same. They do not have the ratcheting system like the original 96s do.

That being said I've decided to go ahead and change the lash adjusters. I do have the tool that you are supposed to use to get the adjusters out. I was able to get the passenger side adjusters out without removing the cam no problem. But have run into a problem on the driver side where the master cylinder and brake booster is in the way. Is there an easier way to remove the last adjusters on the drivers side without removing the cam?

TLDR: Can you get the lash adjusters out on the drivers side without removing the cam. And what other kind of noise could it be if it turns out to not be the lash adjusters? Thanks for the help in advance.

btw

Sounds like stuck lash adjuster or one that wont pump up. if its not lash adjusters then it would be...a rod and its not oging to be that so its lash adjusters.

sounds like lash adjuster to me not sure i can help you with getting the driver sides out. maybe rip off the master cylinder real quick and push it out the way?

Sometimes adding some MMO and running it for awhile can unstick lash adjusters and get chain tensioners to pumpup which can make a ticking sound, just went through this with mine. Doesn't take much 4-6ozs

Were they from Ford or an aftermarket manufacturer/supplier? A number of people have had issues with off-brand lash adjusters in these engines.
