Engine Rod knock only during boost? Bad Turbo?
Im so puzzled. IDK if I have a cracked exhaust wheel or a bad knock only at boost, or a leak...
Just started a week ago under the same conditions, I have this chirping noise, weird noise coming ONLY from the driver side ONLY during 10psi +
I ran the car to 5k rpms with no boost....no engine noise.
I ran the car too 5k rpms with 10psi+ boost and the noise is there.
When the car is running to temp. the noise happens ONLY. Not when cold or slightly warm.
Turbo is 16G, Unknown/authentic? shaved compressor housing, 450cc injectors and stock fuel system @15psi, 3g lifters, 10w40
I do have belt noise that sounds like a rattling heat shield noticeable at low rpms
things to check.
shaft play/ turbo f-ups?
Fix leak between downpipe, 02 housing today, still nothings changed from a week ago
boost leak test
I will Upload a video of the noise tonight... I dont care what the problem is, just hope its not the brand new 6 bolt motor!!!!
