No air filter fitted

Hi all
Soooooooo, The car overheated and never recovered when tweeking, suspected h/gasket. Turns out the gaskets fine. Thinking back, was the air filter fitted ? :see_no_evil::cry::sob:

Conclusion: Air filters are good

Some nasty looking scoring you’ve got there :grimacing:. Out of curiosity, how long was it running without an air filter? Hope you can get it back on the road soon!

Thanks. I hope to get it rebuilt soon. It was only about 2 months old, all balanced forged and lighted, big valve heads and DR650 turbos. :sob:

I was messing about with the boost, I think maybe 2-3 weeks without the filter.

I’m guessing that’s what’s caused the damage as I can’t see anything obviously wrong anywhere, unless something gets discovered on the rebuild.

Can’t believe I’ve been so foolish tbh :cry::see_no_evil::joy:

It happens to the best of us!

Sounds like a pretty extensive build, keep us posted on how you get on.
