How long has it been since you have changed the oil?
As mentioned already, changing it after any intake job is a must.
You did replace the old PCV Valve when you got the LIM kit right?
As for an oil suggestion, I'd not run thicker oil, just get some 10W30 Synthetic oil, it will cost a little more than the old non-synthetic oil, but in my opinion it is worth spending a little more for.
I'd also consider going with a bit bigger oil filter, I'll be going with a Napa Gold 1036 the next time I do mine, based on Mike'* recommendations in a previous thread, I would verify with Mike that it will also work on your 95', I am pretty sure most of your motor is the same as mine, except for things like the MAP Sensor.
I don't think you can totally stop all of the blow back you are experiencing, unless you install a oil catch can for the PCV, I do not know enough about that at the moment, butif it keeps the intake cleaner, then I would like to have one some day.
Normally you should not have enough to create blue smoke all of the time, but a little blow back will always be present inside the UIM, so even if you get it to stop smoking, expect to see an oil coated UIM if you ever have to remove it again.
I am not saying you do not have an issue, you do if you are getting blue smoke, I am just trying to be sure you know a little blow back is normal, it is usually burned off without you being able to notice.
I'd get that oil and oil filter changed, and grab another PCV Valve just to be sure yours is not faulty, it could have gotten a bit gummed up from the old oil, they are only around 2.00-3.00, unless you go with the AC Delco CV8922C, that would be the PCV Valve I'd go with.
