Usually the lifters only tap for a few seconds if thhe van has sat for any
length of time.Ive had mine tap for 15 minutes after a long siesta(3
months)but Ive got 220k mi on an orig engine so what the heck.Ive only
used regular 85-87 octane from new and I advanced my timing to 15deg
beforetdc,and have never heard a ping…the compression is just to
low.These things were made to go in 3rd world countries with 50 octane
fuel….Ed

I have been using 87 octane in my 86′for 3 years with no pinging. I had
a lifter that clacked and I finally got tired of it and put in some heavy
duty lifter cleaner from the local auto parts store and it cleared it up.
If you drive your 87 regularly then it shouldnt have problems with the
lifter bleeding off. Also if you decide to go the oxygen sensor route,
I’ll sell you a good used one for cheap. I was having a smog problem co
purchased a new one and it was not the problem. They’re expensive,
especially if it doesn’t turn out to be the problem. One other thing, it
is also possible that you have a partially clogged, or a couple of
partially clogged injectors. At high rpm they might not flow enough.
Good luck!

How do you know it’s your lifter(s), do you have a vaccuum pump that
runs off the CAM? On 5-cylinder engines, with the vacuum pump, they
typically make a racket, at times. You can remove the shaft that
drives the Vacuum pump, see if the noise stops.
Lifters are easy to replace, about 11-14$ per. Good luck
