Hello everyone, I have built myself a 2.3 turbo from a NA engine, and I'm having some issues, there's a lot I've done so I'll list it here.
-The main issue is a rattle sound with a cylinder dropping out of play intermittently. It happens after 10- 15psi of boost is made.
-Engine decided after my first week of driving, and my first time turning it up to 15 psi from 7, to make a loud rattle/knock and not run. I proceeded to tear the entire engine apart, finding almost nothing wrong. In the head it seemed like a valve spring was spinning somehow.
-Put it back together, didn't run (vacuum went to 15inhg and it sounded horrible). I then tore the head off and used my other head I had from my old engine. Boom she runs, no sounds, good vacuum.
-Took it for a few drives, had some boost issues but ran great. Fixed boost issues (new turbo) put a 10psi spring in it (had a 15 before, I believe other turbo was shitting out) . Now still made 15 psi, pulled like a freight train, actually pushed through the clutch in 3rd gear. On the 6th pull (not WOT about 3/4), boom the same knocking and rattling came back and it ran like crap (as in down a cylinder). I limped it the 0.5 mile home and it intermittently ran good with little sounds, then the bad sound comes back and it runs awful. I parked it and you can still hear a slight sound but still idled fine.
-Im going to put a 5psi spring in it and hope it lowers the boost, I don't need a racecar, but I'm wondering what the hell that knock/rattle is, and why it comes and goes.
-Do I need upgraded valve springs? I've heard that somehow rockers can come out and slip back in. On that drive home the rattle was absolutely insane, sounded like the engine was falling apart, then it goes away and runs fine.
-I can't find anyone with this problem, its an 8plug head that was rebuilt 5k miles ago. And now it's got the same exact knock the other head had.
I apparently can't upload a MP4 or a mp3, I wish I could.
