Doing a tune up on a customers drag car... He had the engine rebuilt 3 weeks ago... So he has 3 weekends of running on the motor... I drained the oil and after most of the oil was out a grey/white thick liquid was coming out of the pan... Any idea what this is? Ive never ran across it before. Not thinking its water since water settles to the bottom and it would have came out first, not last... Assembly lube? He has nitrous on the car, but im not sure if he has used it yet... It also has a fuelie smell to it (just the white portion)... Deposits from race gas? Any ideas?
