The car I recently purchased has had a cam in it since late 2011 and has had 20k miles put on it. I intended to put new springs in it this winter but am wondering if I am pushing it. This year it won't see more than 3-5k admittedly easy miles - it is a cruiser for me with occasional "spirited" drives. So what say you CR, can I wait until the winter when it is down anyways or should I Do it immediately? For what it's worth the builder, who appears to be reputable and know what they are talking about, said 30-40k miles (that seemed too long to me).
Details: PRC springs, titanium retainers, Comp Cams 231/247 617/624 113 LSA. Based on the fluids and such it has had impeccable care to date
