Rwd Sr...Help Please!!

Ok guys so about a month ago my car started making a wierd sound only under acceleration NOT AT IDLE, it sounded like someone taking a screwdriver or something and tapping it in the front of the vavle cover. So i didnt even risk it and started tearing it down. What do you know the cams were a f***ed up. So upon further inspection we found out the oil line the feeds the cams oil had ben clogged. So i trailered it to a family friend whos an automotive engineer. And took a better look he had heard the car before we took it apart so he figured it was the cams so i ordered brand new rocker arms and Greddy Easy cams both IN and Ex. Putt those in correctly and bottoned it all back up and started her up......wasnt getting oil pressure. Changed the oil and filter (witch i should have done first) and got pressure and was spitting fine.whoooo long story lol

But i digress. So with it making the same sound coming from the front of the top of the valve cover i got on here and used the trusty search button, found a bunch of topics describing my exact problem, they all said remove the timing chain guide's, so i did and what do you know same sound. No heres the question. We had it running and pulled the coil pack out cylinder by cylinder and one by one it still made the same noise under slight throttle. So we figured it wasnt a rod... So what in the world could be making this noise..

side note: when we installed the cams he collapsed the HLAS and said i'm going to collaps them all and lat them do there thing.

Whats making this noise?!?!

So much reading. Compress it.

Is it good ole fashion rod knock?... And moved to SR.

I originally thought my knocking sound was coming from the valve cover too..

Pulled the valve cover off about 5 times and found nothing every time.Finally decided it was time to pull the engine for further inspection and what do you know.. 3rd cylinder rod knock.

A video may help us determine your problem.

Especially if you were getting no oil pressure? Prob burned up a bearing

sure its coming from under the valve cover. i use a long screaw driver and place it were you think the noise is. check bottom of the block, water pump, intake, anything the could possibly make noise

Are you sure rod knock? Stock lifters are garbage.

Try Bleeding your lifters. IF the HLAs were compeltly compressed then there was no il in them anymore. And of there is air in them you will egt lifter tap as you increase the rpm.

Submerge the lifter in oil standing staight up. Use a small alan key and put ir in the middle of the lifter then pump the key up and own compressing the lifter until they will almost not compress anymore. Then make sure to reinstall by keep the lifter as straight up as possible so as not to let any air in.
