Hello all,
In a perfect world, we all wish that turbo rattle was nonexistent. Probably would have saved a lot of headaches from owners all around. Deciding to post this threat up on SS since it seems to be more DIY oriented than similar forums. I've recently gone FBO + Inlets/Outlets on my e92. Before bolt ons there was only minor rattle during cold neutral revs. After downpipes and the works, I have horrendous rattle on acceleration, deceleration, and neutral revving. Because I have no issue doing repairs myself, I am considering the option of wastegate arm and bushing repair. This involves removal of the original bushing and arms that tend to go bad over time and installing/welding on new ones. My current turbos (to my knowledge and as far as maintenance receipts go) are the original 105k mile turbos. They don't smoke and build boost fine. This leaves me with two questions in regards to the situation...
1) To purchase core turbos from a partout for cheap and rebuild them on the side?
2) Just purchase the WG repair kit and do it on the current turbos during a weekend?
I've been up and around the turbos numerous times and have not seen any signs of leakage from seals or drain/supply lines. Of course, they would need to be removed to install the repair kit pieces. Has anyone done this repair themselves instead of just swapping turbos and hoping for zero rattle? As far as re-install goes, I am assuming the need for new manifold gaskets/o-rings for coolant/oil feeds along with fluids. Is new hardware necessary? I don't see the point in purchasing the entire install kit all things considered. Any input would be appreciated! Picture of my engine bay attached.
