You need to run compression test first. If you have a burnt valve and do a valve job with the mileage you better do the rings while head is off I did mine in about 8 hrs. with a little help from my father in law. If it's burning oil you should see specs on the back of car. The oil on your tranny could be coming from distributor the o-ring may be bad and it could be dripping down on tranny. There won't be any oil under valve cover unless the engine is running. The only way to check the timing is with a timing light. The only JDM's I've seen are for 95's and older and I think I read the pulley's would have to be changed and the pan doesn't have a hole for crank sensor among other things but it can be done you might want to check out a few posts on team swift on the subject
