Great Replacement Seal!
The seal fit great in the replacement Value Cover I bought. No issues so far and no more leaks from what I can tell.

First Tme Using This Brand
Time will tell how well these parts perform over the long term, as this is my first time using this brand. Everything I could find to read about DNJ engine components was positive. Having received and examined them, they seem like good quality well made parts. Having installed them I find the fit and finish to be top quality. So far I find nothing negative about DNJ engine components. Being a mechanic for the better part of 50 years I can spot junk/cheaply made parts from a long way off!
