Cam reversion
Have dry exhaust till the last inch of the tail pipes , still have reversion . Did someone solve this issue ? |
Cut last inch off. What cam you have? Also when you mention reversion what do you have milky oil or did you physically inspect your exhaust and ports and see moisture... long idle time? |
Yes have a bit of milky oil cam is 244/236. |
The good news is reversion doesn’t cause milky oil, but the bad news is many other things do. Cold water, cold oil, bad intake gaskets, blown head gaskets, failing oil cooler, and the list goes on. A lot more info is needed to even guess. |
The problem is that this is a fresh build everything new gasket, ssm exhaust . Can I do internal flappers on a dry exhaust? |
Everything new. That means everything is suspect. Most likely culprit intake gasket. Have you run the heads, block, intake before without getting water in oil?
|
No had as well but much wrest because of Exhasut failure |
i just went through this issue. I also had reversion issues on top of milky oil. it was a fresh motor with an hour of run time. I found that the intake gasket had a small leak
|
On a full dry exhaust you can mount inside flappers ?

244/236? You sure its not 236/244? I doubt you have reversion with it dry that far out. Something is leaking inside the engine.
Head gasket, intake gasket, cracked block....etc... My cam is a 230/244 112 LSA (small block chevy) with over an hour of idle time in the driveway, no reversion, oil is crystal clear, with stock manifolds, spacers, and risers. I am beginning to think a lot of the cam reversion issues I read about that had me scared to pick "too big a cam" are due to other issues. |
Are you seeing a full milkshake with water in the oil filter or just a little sludge under the valve cover? |

no just some in the top cover |
What is the cam LSA? I always put a small bead of rtv on both sides of the water jackets on the intake gaskets just for a little extra precaution. |
