Has anyone experienced hydrostatic lock when the turbo rocket fluid leaks down into the combustion chamber after shut off? I am asking because I have been chasing an engine noise in my right head since I installed my rebuilt engine over a year ago. I have thought all along that it was a pushrod alignment issue as my rocker arm is slightly out of alignment and I am using larger than OEM pushrods to work with the heavy duty valve springs I have. With many adjustments, I’ve gotten the pushrods pretty much lined up so they don’t rub the head.
While I have virtually eliminated the noise on cold start up (and checked the lifters as well), after I run the car significantly (usually a half hour drive or more), shut it down, and then restart it, I get a clicking noise that lasts a good few minutes or so. It does go away. I cannot see or sense any damage going on, and the thing runs great otherwise, so I am wondering whether I might have some leakdown or something else I’m not thinking of?Any thoughts I would be glad to consider.
