I just had my 454 rebuilt and unfortunately finding out they did a terrible job.
We got the manifold bolts that were stripped in all fixed, water was leaking externally out the top of the manifold.
Next we changed the non adjustable rockers to adjustable and it runs perfect.
Issue is the oil keeps turning milky.
Ive ran gallons of oil thru it, pumping it out the remote oil filter, draining etc.
I had the oil pretty clean without running water in the engine as soon as I ran water thru it the oil goes white.
Im going to pull the valve covers to look for any water leak from a cracked head, cracked manifold.
Any other tips or tricks for tracking down the leak, without pulling the engine?
Thanks in advance

Just bought an ultra jet boat last week and took it out this weekend for the first time. We love the boat just have a few questions

1. Hydraulic lift hatch had trouble opening after its been closed a while. And  it’s pretty slow, maybe just tired. Is it best to add a second one?

2. Steering feels stiff under power is this normal for a jet or should I replace cable or look into a hydraulic set up?

3. Bilge pump is really load- if I replace it should I go with an automatic style? Not sure the one in it is.
Thanks
