I guess Engine #3 ?? Or toss in the white flag and scream uncle?
Dropped a valve this afternoon doing just a simple 3K-8K 4th gear test run, happened on my 2nd run (not even at the track, just local street). Got to about 7,900 and blaaaaaaa -- all sensor readings good except EGT #4 600,500,400... ****!
Pulled the plugs, #4 was wet but no oil, but then I see the valve ... what I see the valve!!! Ugh.
Rev limiter was set to 8100, didn't even reach it. Wonder were Lotus get off thinking these motors can handle 8,500 for even 1 second, let alone 2 seconds.
Maybe this is the excuse I need to finish up a monster motor, I was just hoping it would NOT be so soon after finishing my 2nd motor.
I guess it's time for some of these: valves, springs, retainers -- or go with a new stock head and valves for $500 and call it a day.
