    Well….
    I think I need to replace the intake. Yesterday I noticed some weird condensation/moisture on the bottom of the intake under the thermostat. I cleaned the area and didn’t see any issues, looked solid. I went back to the boat this morning to look things over and clean mating surfaces. I noticed where I cleaned the intake had some moisture and corrosion back. It must be thin and seeping water through. I don’t think it’s my issue but will be an issue in the future if I don’t replace it. I didn’t take a picture of it this morning but will take a look tomorrow and see what it looks like. Also, I just looked closely and there might be a crack.

    Looks like I can order just the lower part of the manifold.

    I all of a sudden have a hankering for a yoohoo drink :smile: .  Sorry, that oil just looks like chocolate milk.  I agree with the crack and replacement.  Definitely don't want to dig back in there another time.

    lol, yea. 
    Lower intake and gasket are on order. Should have them in a few days. I’m curious what the inside of the intake is going to look like once I open it up.

    I have the intake in my garage, went to take a look at it. You can see the moisture starting to make its way through from when I wiped it this morning. Tomorrow morning will really show.

    I’ve been reading that this is a common area for this to happen. During the off season, I’ll see if I can stick my borescope in and check the starboard side.

    Have you check the manifold on the other motor?

    I took the intake apart today. As soon as I pulled off the top, I saw a pretty big flake of paint in the number one injector. I just don’t know if it chipped off or fell in when I pulled the top off. Pretty coincidental. Top side of the intake inside was pretty dirty, got that all cleaned up. I stopped over at the machine shop today, he should be done today. There was a low spot between 3 & 5 and one of the valves wasn’t seating all the way around, I believe it was the #1. The thermostat was a bit@h to get out! I had to use a slide hammer!

    I just said to myself that I should look into all of the injectors. Sure enough, there was a chip of paint in the #5 injector! I know my cool fuels were replaced. They probably didn’t clean out the injectors at that time. This engine always was a little lower in RPM’s but was still within range. I always blamed it on the gauge.

    Heard back from the machine shop. He was pressuring checking the #1 exhaust valve and couldn’t get it to hold pressure. Sure enough, there was a small spot that rusted through! New heads on order $1350 using my valves and springs. The previous owner replaced the heads on the starboard side before I bought the boat, so good there. Just need to check that intake over the winter.

    I found an invoice from the previous owner and same thing happened on the Starboard side heads. He paid $1300.00 just for the heads and close to $4000 total for the job back in 2017. Looks like I’m getting a good deal on the heads.

    Wishing I just replaced the heads last season when I had everything apart.

    That stinks about the heads but at least it will be fixed

    Yes, could’ve been worse if all of this didn’t happen now.
