"Hello everyone,
I have a very stubborn 351W getting a lot of water in the oil.
Heres what I've done so far in an attempt to fix the problem:
1)New Exhaust Risers
2)Pressure tested Exhaust manifolds - Passed
3)Removed intake and inspected lifter valley for cracks - Didn't see any visible cracks.
4)Removed water pump and with intake removed, pressure tested block/heads. Pressurized one side at a time via the water pump ports - Passed, held air pressure for 4 min before disconnecting.
5)New intake gasket and bolts.
6)Compression tested all 8 cylinders. All were around 130-145
Just went out on the water today and the problem was not even slowed. I'm still getting a LOT of water in the oil. Level on dipstick rises about a half inch every few minutes with constant WOT.
The only thing I can think of that hasn't been confirmed is a crack in the intake manifold.
When I removed the intake I took a look at the bottom of it and everything seemed fine.
Does it seem feasible that this amount of water could spray into the lifter valley through a crack in the intake and eventually down to the oil pan?
Is there a way to pressure test the intake with it still attached to the engine?
Any input or experience with this would be a huge help.
Thanks!
- Phil"
