Knocking from engine after track day
Discussion
Hey,
Recently did a track day at Silverstone as part of the PistonHeads Sunday Service a few weeks ago.
Before going the engine was running fine except for a faint ticking, which I understand is a normal trait for an MX5 engine (Hydraulic Lash Adjusters?), but since returning it's developed into more of a knocking noise.
The noise is clear when accelerating and on the overrun. I haven't had a any loss of power and it doesn't make the noise when the engine is cold. Listening to the engine whilst stationary and revving, it sounds like it's coming from the top end, but I could be wrong.
Any ideas guys?
(Yes, I have checked oil!)
Thank you...
