Heres a sr20det tip if you guys dont know this allready.
The stock sr oil pickup is only tack welded in 4 small spots.
This leads to vibration breaking those tacks and the oil pickup falling off. The end result is a blown motor.
The correct way to solve this is to completely clean the metal on the pickup, then using a tig welder (no spatter), weld a thin non penatrive bead around the pickup tube.
Then since there was heat applied to the gasket surface it needs to be decked. You can do this with a file.
2 mins later.
Perfect flat surface for a strong pickup. Make sure to clean any dirt/shavings off before install.
Hope this might save a engine.
