Hey guys, hope some one will have some insite for me on this one.
I have a rebuilt 305cid in my 1980 camaro, and I am getting thick white smoke at WOT. It is driving me crazy because I have rebuilt the motor, it has new bottom end, including pistons, rings and bearings. I also have new- rebuilt mild-performance heads on it.
I have not checked compression yet, I have just moved to NC so I have to get my garage situated, but I did check the plugs and I have oild buring on #3 and #6 cylinders.
The old thing I can think of is I did not have the block checked, bored or honed. I honed them myself with a drill and I honing stone. My thinking is that maybe the cylinders are out of round and the oil is comminf up past the rings, or may be the valves are not closing all the way and it is being sucked through the valve seals. I am not leaning on the the vale seal, since the heads were rebuilt by a repeital machine shop and the only have about 700 miles on the heads, but the bottom end has about 3000 on it.
Well if any one else has any other ideas that would helpp I would appreciate it. I am thinking about finding a 350cid block to rebuild for it, doing it right which haveing it checked out and bored by a machine shop, I just hate to have to go through all of it again.
Thanks, ken
