This is a GREAT video! You're starting to do things on your channel that my channel is pretty much based on, and I LOVE IT! Nice work man...I'll be learning from your experience with the engine rebuild as well. Looking forward to it! There needs to be more channels like ours...DIY power boaters. There are SO MANY sailing channels, but not enough power boater DIYer channels. Keep up the great work!
Brother I love to watch a young person attempt and fix the issues as you find them. We all have the ability if you just try!!! In these case focus on what caused it. The push rod moves the rocker arm to open and closes the valves. So obviously something kept the valve from moving. Could be as simple as a stuck valve from lack of use. However I noticed what appeared to be rust/oxidation on the exhaust port. That concerns me. Remember water can not be compressed. That resistance could have caused the failure. Do some exploring/scope the cylinder before putting in the new stuff. FYI I'm no expert. I'm just a guy that has learned from trial and error. Stay positive and remember you can do it!!!
that part, not connected--is a "Push Rod", the valve lifter is the part on the cam lobe. Cam moves lifter, pushes on push rod, pushes on rocker , pushes on valve-----mikey
You said those engines are Marine Power --seeing the blue color I assumed they are Crusaders. Marine Power engines are painted a Gray color?!------Mikey
Yea of course it brakes down , it's a chevy lol . You need to replace motor to a stock BBF 460 . Ford's are capable punching it to a 557CI . The stock BBF FORDS HP RATING ON A STOCK BLOCK IS 1000 HP . CHEVYS cannot go that far . Chevy cannot do that far lol . The 454 is the highest they have lol lol CHEVY SUCKS !!!
Plenty of 454's in dead RV's. Personally, I don't see the attraction of these exhaust valve burning engines. IMHO, if you repower your boat, look to diesels. Many vessels running GM marine 6.5L Turbo engines. Fairly straightforward swap. You will need to swap props as well. You will see a reduction in fuel consumption. In addition, diesel fuel is much less likely to explode vs gasoline.
Not a fairly straightforward swap (this is nearly his first experience with gasoline engines and quite likely never touched a diesel )( Diesels are only easier than gasoline engines IF and ONLY IF you learned to work on diesels first/before you learned gas.) He'll need to change trans gear ratios, bigger prop shafts, and props fuel systems. at that point you might as well swap out the gasoline generator. By comparison to rebuilding the 454's, (which they don't necessarily need) that an insanely expensive, majorly labor intensive proposition. Just gathering the parts, if you not fluent in diesel, would be a nightmare.
Man that rust in the exhaust port is a sign of a bad or cracked exhaust manifold. Check to see of that valve is seized up and what caused the push rod to puncture through the rocker arm. You can take a socket the size of the spring retainer and take it with a hammer and see if the valve is free. Even though the cylinder wasnt firing, still no reason for the rust in that port. I've been a boat mechanic for 25yrs, if you have any questions let me know.
I am a little behind in the series....but I would also look at the "other side" of that rocker equation. Not sure what would cause that, but I would look into stuck valve...and/or piston to valve interference. I would recommend new exhaust gaskets (and manifold) while you are in it.
Pull off the valve cover see is the rocker arm to the valve broken our come out of adjustment sometimes that will be why the push fraud looks like it's other place the engine was not misfiring when it started So either your push rod or rocker arm is that adjustment and all the lifter itself is broken or the oil hole to build all pressure inside is blocked the worst case scenario is that a low on the cam is worn off but I don't think that's the case cause the engine was not miss frying when you started it
For a push rod to push through a rocker arm is very abnormal as you know. This happened for a reason. The reason it happened is because the valve is stuck and would not move. Why is the valve stuck? You also had rust in the exhaust port of the exhaust manifold. This means you have water in the exhaust port which means you could also have water in the cylinder. If you have enough water in the cylinder then you will have hydro-lock. This means with enough water in the cylinder there is not enough room for the valve to open. I would be looking very closely at the rust in the exhaust port and water intrusion into the cylinder. The water would most likely be coming from rust through in the water jacket of the exhaust manifold.
Way to dig into that project 👍🏻 Take a hammer and hit the top of the valve stem to make sure the valve isn't seized. If it is when you crank it again you'll break parts. You'll need to find a manual or video to show you how to set the valve lash.
sail4horizon / Thinking the same, maybe caused by a hard detonation, he did say it backfired a lot. I would rebuild engine, replace cam, lifters, pushrods, and of course get them heads redone. Better to spend money now than breakdown middle of bay, ocean, ICW, or nowhere close to home port.
Engine of that age I'd buy new rocker arm kit, push rods and lifters.parts for these older engines are pretty cheap and they're everywhere. Buy quality gaskets not cheap stuff.
easier said that done...but down the road...or down the ocean.....you may want to consider doing complete engine rebuilds...by that I mean pull them out and strip them down re build...that is really the only way to get many years out of them....it will be costly and a big job...but it will be worth in the long run...maybe do one engine, safe more money then do the other engine....OR..replace them with diesels...but that is REALLY BIG $!!
real good video 'not a bunch of Hollywood / Tom Cruise stuff things came apart real well, 'not all rusted together like I'd have thought. Pretty cut and dried problem - 'good man!
Great video! I'm also the proud owner of an old cabin cruiser and am still in the early phases of repair and renovation, so your channel really hits home. Love your attitude towards the repairs, it's so cool to learn how things work, and there's something delightful about finding and fixing things, the weirder the better. Keep up the good work, I look forward to the second half of this repair :)
@@CullenCraft 1974 Carver Santa Cruz, 28' with twin Waukesha (ford) 302s. This is my second season with it, currently waiting on a water pump for the starboard motor but otherwise fairly mechanically sound. The head isn't working, fresh water pump leaks, I'm still going through all the various systems and learning a ton! Basically everything needs to be rebuilt/replaced lol! Anyways, you're quite a bit further ahead than I am, but that gives me hope that one day I'll be there with you :) When is your next cruise?
She sounds like a really solid ship. I was planning a long cruise down the Florida coast while working remotely, but unfortunately those plans had to change recently. I was really excited about it too.... Oh well.
@@CullenCraft Thanks, I'm very happy with this old boat :) No better place to discover engine issues than while at port. Hopefully you get things buttoned up and back cruising soon. Long cruise in Florida waters sounds amazing!
There is always a reason for a failure. The pushrods may be lubed by the lifters. If they are not mushroom lifters than they can be pulled out the top. All these things add up. But now is the time to drop in a fresh set. After engine is fired and valves are adjusted, run with covers off and visually inspect that all valves are opening and closing. Its worth the piece of mind to know the top end is full oiling. If not, a cam or crank bearing may have spun.
I just thought of something else I lot of them push rods are hollow to get the oil from the lifter that goes up to the push rod and loves the rocker you might want to make sure that lift or is not stuck With all sludge That will starve the rocker again and the same thing will happen that happens from all starvation Why are in there you might want to check the rest of them to make sure all the rest of my okay I've been mechanic but 40 years so I'll good idea why had
I’m enjoying the journey mate! Looking forward to learning what you find. For sure, like others have said, make sure that valve is not stuck. After every thing is back together not a bad idea to do a compression check. Oh....and make sure you turn the engine over a few times before you add fuel 😜.
I’ve been boating for many, many years and have always done all my normal maintenance....but I’ve never had the guts to jump in and start taking motors apart like you’ve done on your boat. Bravo to you young man!! Keep it up!!
Just thought of another possibility. What if the lifter is stuck in the fully extended position? This could possibly try to push the valve beyond it's limit of travel and result in the push rod pushing through the rocker arm. I would remove the lifter and check it.
That’s a great find. It could have turned out a lot worse than that. We’ve been looking at commanders and a wood constructed constellation recently. Just my two cents, but you might think about making a visit to Harbor Freight tools. For the diy person on a budget a lot of their hand tools are pretty decent. I don’t know how they’d work out in a professional situation being used constantly but for the person that uses them here and there they work good. Might invest in a pry bar. You’ll have more control with it. I’m not sure how the power tools hold up. I’ve heard good and bad about them. I’ve got one of the higher end angle grinders they sell. It seems to work pretty well. Keep up the good work.
Wonderful job your doing . I can tinker around a bit with a motor but I start getting a little gutless when I don’t understand something where you hang in there and find the problem and get the job done and fixed . Good work!!! Your doing a great job . Your boat is going to be like brand new when your finished. Keep on truckin!
A good tip to keep crap from entering your engine while taking apart or putting back together is use a vacuum to suck up all the dirt and little chunks of gunk that comes off things. It will save you an engine. Use that vacuum in every stage of teardown & rebuilding. Oh my, what a dirty carb and intake. I see lots of lack of maint. P.S. I've seen this before in my BBC engines. Cause= collapsed lifter and or rounded off cam lobe. If it's a rounded off cam lobe, tear engine down and look for metal shavings. Happened to me (3) times. 396 427 and the 454. That's when I went MOPAR. Chances are, that rocker arm is laying under that valve cover not attached. That engine needs to be pulled out.
Where can I download a service manual for a 1988 US Marine 454 engine? Where’s the best place to buy good quality parts at the lowest cost. Thanks all.
@@CullenCraft I belive you, but sooner or later you will have to pull it out due to putting new antifouling or something, so you can maybe prep to install that too while you are at dock. I am not sailor but I would love to have those on hehe (front and back Xd)
The tapping sound you are hearing is possibly a collapsed lifter. The engine has hydraulic lifters. But like you said it hasn't ran for some time. Check into videos on replacing the lifters. Good luck and very nice boat man.
Gosh, I’m learning so much from your videos. I must admit I could never do what you are doing. Damm, are you saving a ton of money by doing this yourself. Are you a mechanic by trade ?
This is my first time doing all of this! Just a lot of reading and research. My philosophy is, it's already broken... Might as well give it my best shot!
Well your situtation was better when we were fixing our port 20 year old 350 horizon merc motor with 300hp that the inside was literally rusted out due to salt water leaking inside and corroding it like hell. and we had to replace a entire engine block with pistons rods all of that most costly thing ever over 10K with installing it and taking out the old port motor. Its sad because its the main reason we had to sell our 29ft sea ray amberjack but we are hoping to get another boat soon
As a mechanic you should replace all the rocker arms as the the sockets in them wear out so if one pushes through they are all pretty worn out and will follow suit in tine maybe not tomorrow but better safe then sorry . just a quick tip like anything if you do your right front brakes on your car you also do the left even if they are not as bad . New rockers, pivots and pushrods are always money well spent...
I ended up getting most of my parts from a local engine parts store in Jacksonville. They deal in big blocks all the time and had all the internals. The marine-specific parts came from a variety of online stores like hodges marine.
I'm curious as to why one would buy a boat that you can't hoist the engine out without dismantling the boat? You got lucky on this one. I sure didn't when that happened to me.
Long story short: because its a good boat. Longer answer: because there's enough room inside the boat to pull the engine, mount on a stand, disassemble, and rebuild in my own living room if need be.
I have the same motors in my boat I’m not getting spark I have the old point system could you possibly do a video on that or point me in the right direction
Cullen, thank you so much for your videos - I'm a big fan.... Say, If an engine needs to be rebuilt - is it always done in place or have you ever heard of fully pulling the engine out of the boat? I'm considering buying a project boat - have heard both engines need to be rebuilt. Detroit 6v92s.... I've found rebuilt 6v92s for $4,250 - might be easier to swap the motors out vs. rebuild in place...
My boat is built around the engines. There is no door or window big enough to pull them out in one piece. If yours are easy to remove, go for it! Would make the job a lot easier.
This dude turned a 15 minute job into a 3-4 hour cluster fark. I would have removed the valve cover first, not sure why he separated the carb and now has to drop the dist. shaft back in. RMEz.
Its fun. Sure i could speed run it and get it over with... But I enjoy taking my time. The intake manifold needed to be removed anyway. Oil leak out of the old gaskets. Got some new ones waiting in the wings.
I’m from Maine and have a fishing boat. I enjoy your videos and your appreciation for your boat! Wishing you the best of luck and can’t wait for more videos
All that metal from when you ground the camel down and dish the back of the lifter is floating around in there taking up making up more clearances on the connecting rods and main bearings and pretty soon it's going to come to the side of the block cuz you never took it out to clean it and fix it right you're just a patch kind of guy instead of fixing it the right way
I am learning so much from you, keep on going! I am trying to buy a local Commander and it’s rough- you’re helping me understand what I am going into.
Commanders are the king of the Chris craft fleet. Good luck!

These have been poorly painted blue by another owner, it seems. Lots of over spray and flaming paint.
Put a new rocker on it...just chevys ..0 out 1 full turn on valve adjustment.
Can you show how to winterize the engines
I don't actually know how, I live in an area that never truly freezes. If I knew how, I would.
Broken rocker arm
I would replace all the rocker arms, push rods and lifters. Don’t risk it.
Just heard you say your replacing them all. Awesome
Yea of course it brakes down , it's a chevy lol . You need to replace motor to a stock BBF 460 . Ford's are capable punching it to a 557CI .

I've got great news for you. I just posted the series finale and took all your advice! Check it out!
Common problem with the 454 engine. That is what was causing the backfiring. Replace the rocker and push rod. Put it back together and move on.
Hey! Get rid of the slotted-strap hose clamps! Replace them with stainless T bolt clamps. Far more dependable!
If you have the money i would go and get some nice aluminum intakes and new holly 600 carbs

Common problem with the 454. And just a bit of advice. If an engine sounds like that, don't continue to use it without having it looked at. Lol
Maybe you should think to invest in bowthruster if it is possible to install. Could be big help in big boat
I've thought about it! That's a big job. And scary to cut two big holes in the bow!

But salt life necessarily
Easy fix, roll all your lifting rods on a flat surface and replace accordingly.
It’s a bent push rod pull valve cove off and replace you damn luck you saw that but with that loud ticket think pistons already made contact
Bent push rod due to valve float high rpm,or sticky valves
How about EFI
@4:54 that's an intake manifold.
It totally appears you have been doing some research. So nice to see you learning so much about your boat!
And gaskets
I missed out on a beautiful 38' 1968 Chris craft for $14,000 in Hamilton ON Canada
Those 2 engines could be worth more than the boat. I hope the boat never gets parted out for parts
Well done!
Looking forward to hearing the engine run again!
* necessary.
Lmao one 454 and 1 453
that's a great find good work...
good job..
It's not chatter it's connecting rods coming loose
Double hose clamp everything
The tapping sound you are hearing is possibly a collapsed lifter. The engine has hydraulic lifters. But like you said it hasn't ran for some time. Check into videos on replacing the lifters. Good luck and very nice boat man.
Great news: I've repaced all the lifters and pretty much the whole top end... Including the camshaft. Full video coming soon.

You're 100% correct! I replaced all the parts you mentioned in the next video in this series.
Are you related to Aging Wheels Guy? You look and sound very similar including sentence structure and word choices.
I love Robert's channels! No we're not related. But I'm probably pulling a lot of stylistic stuff from him subconsciously.
Thank you so much for this content. Really appreciate you going the extra mile to film, knowing what a pita it is to work on these.
For sure, filming was half the fun!
Hello new to your channel. Have you posted part 3 of the engine top rebuild.
With Regards
Working on it right now!
Its going to be one heck of a video. Already got 6.5 hours of raw footage, and its not even done yet.
Hello Cullen - can you please share where you ordered your parts?
I have the same motors and looking to do a full overhaul on both in the next months.
I ended up getting most of my parts from a local engine parts store in Jacksonville. They deal in big blocks all the time and had all the internals. The marine-specific parts came from a variety of online stores like hodges marine.
You need a compressor and air tools .
I'm curious as to why one would buy a boat that you can't hoist the engine out without dismantling the boat? You got lucky on this one. I sure didn't when that happened to me.
Long story short: because its a good boat.
Longer answer: because there's enough room inside the boat to pull the engine, mount on a stand, disassemble, and rebuild in my own living room if need be.
I have the same motors in my boat I’m not getting spark I have the old point system could you possibly do a video on that or point me in the right direction
Possibly a bad coil, but check every single ground connection that you can
9 times out of 10 it's something very simple like a loose connection
Valve is tapping it can be replaced easily

My boat is built around the engines. There is no door or window big enough to pull them out in one piece. If yours are easy to remove, go for it! Would make the job a lot easier.
@@CullenCraft Thank you..... :-)
What's better then one muscle car engine... TWO muscle car engines!
Hell yeah!
Good job solving the issue.
Funny but definitely entertaining.
Valve lifter = push rod
I've never seen that before
Closed cooling sucks ...
not in salt water
Agreeded. Totally necessary
Finding that small pc still up in the head was so lucky If that got down into the engine you might be buying a new engine
Gerry Dunne not necessarily buying a new engine, complete rebuild would have to be done
Cullen i really like these videos. Your doing a great job. I did see the bottom paint video. Did you check for blisters? Regards, Peter
You sure got lucky!
Good video,have fun
Call a real mech
I was right
I know diddly squat about engines, however that makes me admire your courage and enthusiastic cheerful approach. It's great viewing.
Thank you!
Your
This dude turned a 15 minute job into a 3-4 hour cluster fark. I would have removed the valve cover first, not sure why he separated the carb and now has to drop the dist. shaft back in. RMEz.
Its fun. Sure i could speed run it and get it over with... But I enjoy taking my time. The intake manifold needed to be removed anyway. Oil leak out of the old gaskets. Got some new ones waiting in the wings.
I’m from Maine and have a fishing boat. I enjoy your videos and your appreciation for your boat! Wishing you the best of luck and can’t wait for more videos
Thank you! This means a lot. Enjoy the water!
Damn never seen that go threw like that wow
Lol, and buy a power tool
All that metal from when you ground the camel down and dish the back of the lifter is floating around in there taking up making up more clearances on the connecting rods and main bearings and pretty soon it's going to come to the side of the block cuz you never took it out to clean it and fix it right you're just a patch kind of guy instead of fixing it the right way
