Lifter noise after warmup
Hello guys, I am new to this forum and Alfa engines as well.
I'm racing in spec series called Formula Alfa in Georgia. These are single seater slicks and wings cars with 2 liter TS engine. Problem is that my car started to make very loud lifter noise. Once started cold the engine sounds very smooth and nice but after 2-3 minutes or so it starts to make lifter ticking noise which becomes louder and louder as the engine warms up. After I drive it for a while at mid RPMs the noise goes away and it is not audible even at idle.
I use Elf competition synthetic oil 5w50
I also have a mechanical oil pressure gauge and pressure is good, around 2 bar at idle with warm engine and at mid RPMs it already hits 6-7 bar.
Common answer would be that oil is getting thinner but the engine started to make noise instantaneously. One day I started it up and it started to make noise after warmup
