The aluminum cover is much better than the plastic junk that was on before.

1984 4.2, 258 ci. Engine. No new studded bridges needed as there are no studded bridges on this engine. Had to tap two holes in block. Carb sided.
Only 2 5/16 screws needed. Carb side. Tap for these.
% 1/4 needed not 2. 1 on each end and 3 on battery side.
Prompt handling and shipping.
Questions
Mark D.
The Installation Instructions say you have to tap 5 guide holes. How difficult is this?

Tapping those 5 guide holes in the OMIX 17401.14 Aluminum Valve Cover can range from moderately easy to slightly challenging depending on your experience and the tools you have. Tapping these holes isn't inherently difficult, but it requires patience and proper technique. If you are unsure, consider watching some videos on how to tap threads by hand before you begin. Taking your time and using the right tools will greatly increase your chances of success.

Will it fit on 1990 YJ 4.2L

This only fits 81-87 CJ and YJ applications. It will not fit the 88-90 4.2L YJ's.

Would this fit on a 258 4.2L 1988 jeep YJ?

No, it will not.
