MORE LIKE ORIGINAL EQUIPMENT. DON'T BUY THE ONES FROM PIONEER. THE AREN'T FORMED 100%.COST ME A ENGINE REBUILD.CRANK SENSOR WOULD NOT REACH RING. (NO SPARK) ENDED UP FLOODING ENGINE AND GAS MIXED WITH MY OIL AND RUINED BEARINGS AFTER I GOT IT RUNNING.SAVE YOURSELF AND BUY THIS DORMAN PRODUCT.THANKS AGAIN AMAZON!

Worked as intended
Appreciate the crank sensor plug since it was going in a boat with no crank sensor. So much more expensive than just buying a seal though, no idea why GM switched to one-time use timing covers.

no problems with the product or delivery
well made, BUT difficult to install without dropping the oil pan.

Not bad, thought it would be pretty lousy quality but it held up ok and stopped leaks
The entire design is very stupid and GM went back to Aluminum housings after they stopped producing this design. But regardless, this replacement was not bad, came with the bolts, everything went in fine and stopped the oil leaks on the vehicle. I'm satisfied.
