First of all, thanks for taking time to read this, as I am getting very frustrated...
I was preparing to put my car on the trailer for FFW this week and noticed some "clicking" coming from the engine bay. So, I looked around and "felt" around with my stethoscope (sp) and could hear the noise really bad under each valve cover and in the upper intake (loudest). The noise was a very quick and rythmic clicking, that increases with RPMs. At first I thought I had a couple of loose rockers or something, so I started checking for those to no avail... I then started looking at the rockers themselves and noticed that they were a little "far down" on from the center of the spring. After having someone else (mechanic) look at it, he thought I might have a push rod that was a little too long. Without the ability to really measure (although these are what the engine builder told me to buy...) I spoke to TFS and they tended to agree. So...I ordered a couple of shorter sets and put them in the car.
After setting the valve lash, I started the car back up and the noise was still there... I then decided to adjust the lash with the valve covers off and the car running. I was able to eliminate the noise from the passenger side, but not the driver's side. The noise doesn't seem to get quieter or louder when I make any adjustments on the driver's side.
Do you have any suggestions? I currently have the following setup:
Not sure about the PSI on the oil, but based on the stock gauge, the oil pressure is normal around 3/4. I am too starting to think that it is bad lifters, as they were the only thing that I didn't replace when I rebuilt the engine last season.
Any idea how to confirm that the lifters are bad prior to buying a new set?
make sure you adjust your rockers in the firing order to make sure that they all get the same treatment. My car was the same until i found out how to really adjust the rockers. Definatly could be a lifter though. Take them out and see if the plungers are shot.
