I have a chevy engine question. I have an 86 4x4 with a crate 350 that came with a mild crane cam. Two years ago the back cam lobe wore out at 90,000 I had a new cam installed by a good shop owned by a bronco nut. It's very quiet the 1st ten minutes, after that it starts to make clicking sounds like there are loose rockers arms. It will quiet down after it colls down.
The oil pressure reads 60 lbs highway, 30 lbs at idle. I have mobil one in it with ZZDP. The shop owner tells me that this noise is normal, I know that this noise is not normal.
I'm planning on starting with new cam saver lifters, pushrods, Kool nuts, etc. Does anyone have any ideas as to what causes this, I'm stumped.
