OMIX Polished Aluminum Valve Cover Reviews
Steven D.

Had to tap two holes already present on my 87 YJ on the driver's side of the head. The valve cover looks awesome but I do wish it would've come with more bolts.
Questions
Donald R.
is this a direct fitment to the 87 YJ 4.2 with no drilling?
The OMIX 17401.09 Polished Aluminum Valve Cover is marketed as a direct fit for the 1987 Wrangler YJ with the 4.2L engine, but in practice, it is not always a "no-drill" installation.
While the valve cover matches the factory 4.2L (258ci) bolt pattern, many Jeep owners with 1987 YJs and later-model CJ heads report that they had to drill and tap two additional holes on the driver's side of the cylinder head to ensure a leak-free seal. This is because this aluminum cover is designed to replace the original plastic or stamped steel covers, which often utilized fewer mounting points than this heavy-duty cast version provides.
