Obviously I am new to the forum and received a ton of help from you guys in the past week. If you read my other thread, I had Alky injection issue and with your help as well as a phone call to Julio, I was able to get it resolved. I just got the car which makes this even more aggravating. The car was suppose to go to the body shop Tuesday to get sheet metal and paint.
Once I got the Alky kit operating right I started to bring in more boost a pound at a time starting at 10lbs. My O2's were on par floating from 750-850ish with 0KR as I brought up the boost to 15lbs. I turned it up to 16lbs and made another pass which again gave healthy Scan master readings.
I get out of the car to play with the boost controller again as I was trying to get her to 18lbs and be done....
I hear from car Knock, Knock, Knock, Knock and my heart sunk. I run back to the driver side and look at my oil pressure and I am floating at 40lbs which I know is plenty fine. Even now, If I start the car cold it idles with 60lbs of oil pressure. When I purchased the car, the car didn't hesitate on start up. Now it has a slight miss on startup and once it warms up its fine.
I started listening more and more with a stethoscope and I thought I pinpointed it to the rear of the engine. But today I really cant find a exact location on the motor. I pulled the VC off and checked the rockers and shaft while the car was off and running and everything is tight. The knock gets louder, faster and more pronounced as I add RPM. I thought maybe collapsed lifter so I pressed down on the pushrods on Cylinder 3 and 5 and they are solid and not spongy
I did read that the TQ converter bolts to the flex plate can sometimes come loose. I get under the car and they are all tight as nails.
I am already debating on doing a full rebuild, but if I don't have to, I don't want to. Being new to the motor, anyone have any thoughts?
Here is a video.. let me know what you may have in mind.
