My 91 has done 210k miles. The tappets are only just starting to tap if i cane it too hard. The valve stem seals are worn aswell cause it smokes a tad when i pull away or going down hill, simple job tho, just cant be arsed to get up and do it, i use the cheapest and thickest oil i can find at the moment, no point in putting good stuff in as its only the person behind me at the lights that gets it in the face!!
