Here's the situation, the motor is has less than 250 miles on it. I had it at the track a few weeks ago and it started to tick in the staging lane. Sounded like a loose rocker. I pulled the car into my buddies trailer and pulled the valve covers and the found nothing wrong. I put the covers on and fired the car and it didn't tick and sounded fine. I pulled the car out of the trailer and went to move it and the ticking came back. I called it a night and went to drive it home. It continued to tick so I had him trailer me home. I pulled all the rockers and checked the push rods and all looked fine. I put it all back together and I don't have the ticking sound any more but I get this pulsating squeaking sound like a bad pulley tensioner or something. Like squeak-squeak-squeak and so on. I pulled the belts and the sound is still there. The oil pressure is good. It was around 50psi when I started it. The squeaking sound comes once the car is started for a few seconds (say 5-10) but doesn't go away. I first thought the ticking was due to the Comp-R lifters or a bent push rod, now I am clueless as to the problem. I pulled the dip stick and didn't see any metal shavings. I will drain the oil and check it soon as I get a chance. Anyone experience anything like this before???

I'm wondering if there is a header leak or loose or something like that. I've gotten what seems like a valve tick and I had a loose header bolt. The other thing it might be is a noisy injector. Mine tick more than stock.

The header bolts are all tight. The ticking I am not so worried about the squeaking I am...

I was thinking if a header was loose you could be getting squeaking with engine rock from that... Maybe a loose motor mount? If it's coming from the front of the engine with the belts off and it's inside, I'd guess oil pump. Up front I would guess the front seal is new and tight. When I changed my cam and installed a new seal up front and turned mine over by hand I got a squeak for a couple of weeks. Just trying t give you some ideas from my experience.

My loud squeaking sound turned out to be two rod bearings. It had a ticking sound that turned into a nice loud knock. Hopefully your luck isn't the same. I'm sure you will find out when you drain the oil.

Are you still on the stock, original water pump, or have you pinpointed the squeak to the valvetrain area??

had a buddy that developed a squeak-squeak-squeak that stayed with the belts on/off, tightening the headers...didn't matter what he tried, it wouldn't go away. good oil pressure. he remembered developing a tick after taking it to 6400 with stock 80K springs, which turned into this squeak. tore it down to see if we could find the source...and we did. he lofted a lifter causing it to shred the hardening on the roller and flat spotting it.

I have a feeling I will be looking in the lifter area. All my bearing were coated and I have an aftermarket oil pump. Oil pressure is good.
