Like other people that have purchased JDM motors, my timing belt covers were cracked in a few places. It’s a long trip from Japan and you can expect these kinds of things to happen. Seal up any cracks well – you don’t want to risk something getting in and shredding the belt. I purchased a set of used covers from a NASIOC member, but JB Weld would have probably worked just fine. I also went ahead and painted the covers with Krylon Fusion (plastic bond) satin black paint. The covers cost about $100 new from Subaru, whereas I paid much less for the used ones and paint.
I added part numbers for the JDM covers to the compendium for reference.
