2010 SAN 230 - PCM 409 ticking diagnosis

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

We've recently purchased a used 2010 SAN 230 and during the demo there was some clicking from the engine. I was assured by the in house mechanic that the noise was normal. Can someone with a PCM 409 confirm? Is this sound normal?

Thanks!

Davis

	Sounds like a sticking lifter but really need a mechanic's stethoscope and need to vary RPM's. Does it go away with increased RPM's ? What is the oil pressure gauge reading during this ticking? I'd keep looking if the seller says that is normal. It is not. Compression and leak down test should be a mandate on this and any other boat just to get a good read on health. Would be good to know more detail--how many hours, what does the crankcase oil look like, service history, type of use, what oil Change intervals were followed and what oil was used etc etc

	2nd on the valve lifter. Also, some fuel injectors make a clicking noise when they open/close.

	Fuel injectors sometimes at startup but I don't believe that sound is from a fuel injector. Let's get some z06 feedback from this thread. Might also ask on Planet Nautiqie where those z06's live in droves!

	Hello, The engine was cold while doing the demo if that helps. Unfortunately, we've already purchased from out of state so this is my problem now. I will be taking it into my local nautique dealer when it arrives next weekend. Any other opinions are welcome. I've also posted in Planet Nautique for opinions. Thanks

	Welcome! Hopefully it's something small. Do you plan on boating in Samammish? I know several people who have used Pacific Nautiques for winterizing etc. certainly a small shop, but they must sell a lot of boats, Lake Tapps is full of boats with their sticker on them.

	Thanks for the welcome! We plan on boating Lake Washington and Samammish. Crossing my fingers that it is something small as well. Pacific Nautiques will be the one to look it over and diagnose. This our first boat so i'm hoping we don't start out with a huge problem.

	Well if he seller says the problem is normal then they probably won't mind paying for a new lifter or valve job. You're lucky to live near two of the most beautiful lakes in the USA! I'll have to look you up when I'm in Bellevue next trip out!

	Flexplate is another possibility. That is in between the engine and transmission, attaches to the flywheel. In that case, some clicking is somewhat normal at low rpms.

	Thanks. The boat was in neutral if that helps. From what it sounds like, most likely lift valve.

	Ouch I would have to say lifter for sure not a damper plate rattle Hope you got a good deal that leaves enough room for valves/ lifters

	Honestly I'm betting one sticky lifter and maybe free it up with some running. Z06 engines are notorious for lifter issues and it's not a hugely expensive fix. Intake manifold and valve covers then nuts and bolts. Corvette guys say to use Lunati link-bar lifters to replace the OEM lifters--I have no idea really. . 3-4 hours labor should get it done at a car dealership--I'd think the same for a boat dealer if they have a good engine "wrench" on staff.

	Thanks Tryathlete. I'm hoping you are right and a full tank of 92 octane with marine stabil will free it up. I'll be sure to keep everyone posted when our local dealer takes a look. If it does require new lifters, the out of state dealer that we purchased from will be hearing from me.

	Just remember every used boat is going to have issues. Work through them and put them Squarely behind you and you'll be pleased when you get there.
