Hi, so I have a '68 327 SBC, new to me 2 years ago, I know nothing about the history. I've been told its got a high lift cam from how it idles. Since I've owned it has smoked out one tail pipe. Determined that cylinder 4 was the culprit because of a fouled plug and headers in that cylinder only. Last winter I replaced the valve stem seals on 4 but still seems to smoke, I also noticed the rocker stud on the intake was stripped. Just today I replaced the rocker stud and went to adjust the valve lash. I had a hard time finding TDC on 4 because the valve was not moving. Removed the rocker again and confirmed that thru a full 360 degrees of crank rotation the intake pushrod on 4 did not move. So ripped off the distributor and intake and pulled out the lifter. It was quite concave on the bottom surface. So I removed the exhaust lifter too and it was very flat. Tried to peer down the oil port to see the cam but could not make out very much.
See the attached pics. I'm assuming both lifters are supposed to be flat? And these are hydraulic lifters right? Based on this pic, what are my options? Can I just replace this lifter? Should I investigate more? Is my cam likely damaged? Should I check the other lifters?
I would really rather not remove the heads, as I'm in way over my head already. No pun intended. Thanks in advance for any and all advice.
Should I put this engine up for sale and get a new 350 from Jegs for $1500??
Cheers
