Nothing hydrolocked or frozen. Engine running when i winterized it. Since the heads were redone and installed, engine was started and run with no abnormal sounds. Only issue was lack of oil coming up thru pushrods. Oil pressure was a little over 60. Lifters should arrive 4/11. I'm hoping to get...
Nothing hydrolocked or froze. exhaust valves were rusted. I have run the engine since re-installing the heads and engine sound good. It was winterized, oil changed, and raw water system completely drained. I installed 2 bilge heaters to prevent freezing temps in then bilge (theybavtually work...
I checked the lifters over the weekend. I could visually see 2 had what looked like sludge on the top of them. The others did not have any spring to them when i tried to depress the pushrod. i'm going to install all new Lifters, as opposed to trying to clean them, after, after i change the oil...
I did place the new pushrods in oil overnight. i changed the oil 2 times before taking everything apart. When I started the engine It ran for about a minute and I shut it down. I didn't want to run it any longer the way it sounded. i did not use a priming tool. I plan on doing that this...
To add some background - before engine was disassembled, it was running, roughly of course, and pumping oil up to the rockers. The engine sat for about 8 weeks before I could restart assembly. Should I have removed lifters and pumped them up with oil?
i have an inboard merc 7.4 gen vi (it is a 2000, but I cannot find serial numbers on either engine). I had the starboard engine cylinder heads redone after a few stuck valves, from water in the oil. upon installing the new heads with all new gaskets and bolts, i am not getting any oil to the...
I purchased the boat with these engines and the PO (2nd owner) knows nothing regarding the engines. Spoke to his mechanic and he has not done any work on the engines other than usual yearly maintenance. All I know, from paperwork found in the boat that the original engines were replaced in 2005...
I have twin 7.4's Gen VI MPI's. These were distributed by Sea Max, so i cannot find much info on them. The engine serial nbrs are unreadable. The paperwork says they were produced in 2000 and installed in 2005. I just had the cylinder heads done on the starboard engine due to stuck valves from...

So i finally (after over a year) got my parts from my mechanic and put my port engine back together. What I thought was a broke timing chin turned out to be 2 frozen valve and a cam pin sheared off. Engine starts up and runs good. problem is i'm not getting water thru the risers. while...
