Timing cover
The product was a exact fit, the only problem was the thread insert for crank position sensor hold down was loose in the bore and I had to JB Weld it.

Weak bolts
The cover itself is decent quality but the bolts that come with it are junk before they were even at torque 18 foot-pounds i had two of them break on me. i wouldnt suggest using the bolts that come with the cover unless you want to drill out broken bolts from your engine block

Decent product
The cover fits perfectly. The bolts are ok. The how to/diy video, however, is wrong. The bolts are only suppose to be torqued to 6.5ft Lbs and not the 18ft Lbs like the video suggests. A previous review stated that the bolts are garbage, but he most likely was fallowing to video like I did and over torqued and snapped the first bolt like I did. So all in all the product is decent, but make sure you do extensive research and get the correct torque specs. before doing this on your own.
