Now in the past two weeks I have had five performance customers have their Preludes just start drinking oil overnight. Two lost motors and the other three lost v-tec first and brought them in, catching the low level. None had the oil light come on. I keep good tabs on these cars and know that they started burning it out of nowhere. All had mild bolt-on's, nothing extreme. Has anyone else been seeing this. I haven't had a chance to get one out and open yet but I'm assuming the rings are letting go all at once. The lack of warning signs is leaving me concerned about using the H series. All were around 80K and one of the ones that blew was an SH w/ 44K.
