    All the oil in the intake ports would lead me to think maybe there's a valve guide problem.

    Isn't that a bit high? Also, I suppose if you put too much oil in the engine you'll have problems also. (sometimes it's the simplest of things...)

    My oil pressure is that high without this issue.

    correct me if i am wrong//

    the torg heads are have a radiused valve seat

    old valves from an old camaro.. not sure you have that one correct

    those are not the best of heads.. inexpensive but not the best... still i would ask someone to look at the heads themselves

    Default Oil Smoking

Let us know if it is soaked in oil inside the tube. When I did my rebuild I had oil blowing past the PCV and into the intake manifold via this rubber tube. I installed an oil catch can to resolve the issue of oil being sucked in to the intake and mixing with the air fuel mixture for burn.
    I am reading this post and damn if it is not a direct quote of the problems I have on a BB after a rebuilt. Difference is, the heads were redone with new everything including cut for and installed PC seals. Supposed to be great.

    The smoking is predominant after totally warm - metal expands. One garage said since the bottom end was bored etc they would think the cylinder walls are not a perfect bore top to bottom and when warm, oil sucks up the walls. I have tried 3 differnet intakes and 3 different carbs with no affect. My PCV lines are not wet with oil and the valve covers have baffles in them.

    I with stupid luck may have stumbled onto something this week. The timing was real hard to set and the engine bucked when warm and then fired. I pulled the distributor, found tdc and put it back in like the book shows on a BB - rotor pointing to #1 tower but having #1 aligned near the vacuum can, which was 1 tower clockwise. This also with a MSD distributor put the mag pickup dead center in the pickup coil. Changed the wires around and presto the timing was easy to set and did not show signs of being super advanced. Talked to an "expert" and he said you most likely had a problem of pulling fuel from the boosters and actually pulling oil from the cylinder walls because of the super advanced timing - called it a reversion process. Anyway after an hour of running the amount of smoking was reduced to almost nothing. I probably have a ton of oil and gas on the valves, in the pipes and in the mufflers. Just maybe......

    Sorry it was so long, just sharing an experience that might be something to look for. Still think the bore job was suspect.

    Default smoking engine

    Dont know if this could be the issue or not but I work for caterpillar large engine division and we were testing a new engine and it ran great till warm and the oil pressure started dropping. To make a long story short assembly had installed the rings upside down. We blew 125 gallons of oil out the exhaust. Yes 125 gallons in a matter of minutes, thease aer big engines. I couldn't remember there is a up or down side to car engines but someone out there probably knows.

    The lack of valve stem seals is almost a guarantee you gonna get oil going into the engine...apart from that , it could be that the bores and rings havent broken in properly and the bores are now glazed....
    Check to see that you have the breathers working correctly , one side of the engine needs to go via a pcv valve to vacuum and the other side needs to be vented ..
