Over a year ago I put in the e303 cam with new lifters and just recently I had a sound coming from the passenger valve cover. We pulled it and found to what looked like a collapsed lifter. They were under warranty so I put brand new ones back in started it up and the sound was still there . Is there something that could be making them collapse? I have stock length gt pushrods and rockers on gt40 heads. Also my oil pressure was inconsistent while this was happening...oil pump finally going out maybe?
thanks
