I am shocked why some of you didnt just build your own car instead of buying one.

Is the sound a tick, tap, or knock? I would never have given it a second thought if I hadn't read this thread. I thought this was a normal sound for an engine. My 1993 YJ's engine sounded like a sewing machine too.

Nothing is getting blocked inside the head/exhaust manifold and stopping the flow of exhaust to the atmosphere. There is no increase in density occurring because there is no constriction of the gas flow. The exhaust will escape because the cylinder pressures greatly exceeds the atmospheric pressure. If what you are saying is happening, the exhaust gases are being constricted, the engine would not function properly and completely stall. Yes, there could be a build-up of excess heat because all the cylinders exhaust through this singular passage.

As I've stated many times before in this thread, a lifter is being starved of oil right from the very beginning of the engine's life. Every lifter has it's own internal spring that does the job of supporting a zero valve lash gap but for only so long. Without a constant support of oil pressure this internal valve spring will only last for so long. I physically observed the one lifter that failed in my Jeep. Compared to the other lifters there was no resistance remaining, no force to keep the valve lash gap to zero. THIS IS WHAT CAUSES THE INFAMOUS TIC.

This is the last time I will make this statement. Everybody that doesn't understand the hydraulic valve actuation process should Google it and do some reading. A lot of very false accusations that are rampant throughout this thread would end. Please do us all a favor and do some research and LEARN. The internet is a very powerful tool LEARN HOW TO USE IT. Goodbye.

All the haters saying my jeep is junk can pound sand it's my bank account that pays the payment, and i'm not saying anyone here has said that before you try to jump down my throat. Without this thread and the constructive advice found here i would have had a lot harder time with the dealer. Most of the problem seems to be getting the dealers on board to do what they are suppose to...fix the issues. People's actual experiences and symptoms are what this thread was suppose to be for not a bunch of childish bickering between each other. Some people need to get a grip and take their frustration to the dealer where it belongs. As for useful information, when i get my invoice i will repost what is on it, wether i have an aa head which will likely be an original defective head that will fail again or it is an ab reengineered head that should fix the problem completely. Until then my jeep sounds a thousand times better than it did before the replacement, i never had a cel and the slight hesitation is gone. To all of you that have contributed useful info on this issue i say thank you, to all the others i say piss off your bullshit has made me unsubscribe to this thread so your childish banter will fall on deaf ears.

This new head really was an outside of the box design.
