If there is pressure in the case unless you have a good locking oil dip stick, you would shoot the dipstick right out of the block, I had a blown 327 which blew the dip stick right out of the engine due to blow-by.

That's probably true. It's just odd that the oil pressure jumped up the way it did and then I find this. To me, it looks like the cylinder not firing hasn't been going on very long since there is still some carbon soot inside the exhaust port. There's also oily residue inside the exhaust port, which is not very comforting. If there's a good point to all of this, if it hadn't been for the header bolts snapping, I probably would not have found out about this issue until it was way too late.

Obviously mine runs better than yours. Hell blown motor,broke gear box,how many props have you tore up,running on 7 cylinders and high oil pressure from a burnt piston. You are right up there with that Obama lover from Alaska as far as dumb shit I've seen people post on here.

Take this as a grain of sand but, a LS engine doesn't take 15w-50 at all and i don't care what anyone says. The max oil thickness you should be running is 10w-30 you could also buy it with a zinc additive. If you switch to a thinner oil you will have less drag on the supercharger and also less drag on the engine. The journals in a LS aren't the same as the old school engines back in the day. Now all engines have tighter clearances. Like i said grain of sand because if you listen or not its no skin off my a** as i don't have to pay to fix it.

Took a look inside the cylinder with the bore scope. There was some vertical scoring and pitting on the head of the piston. My guess is broken oil ring. Motor is still under warranty and Marine Power told me to use whoever their local distributor recommended to use. Just so happened they recommended one of the best engine shops in South Florida. We'll see what happens next.

I wouldn't discount the LSA. I got a little over 170 hours out of it. Heck, if I hadn't found this, I probably could have gone 200 before she blew to pieces. I've been saying for quite a while now; buy a purpose built motor. Waterthunder, TKE, MAS, MAST; anything that's built to take the punishment. Obviously, my Beaner motor gave me what I had coming. You all know the old saying; you get what you pay for.

Looking at spark plug that is fouled, would suggest a new set of plugs. Vertical scoring in the cylinder is not uncommon.

Exhaust port does not look like culprit cylinder is pumping oil.

Noboby knows if you put a new plug in the engine and monitored burn for a short time.

Possibly, she is perfect after you put 5W30 oil back in the engine and a new plug?

I thought the same. Put new plugs and check header temps with a heat gun. U will know pretty quick if it's firing or not

I have always been told to go lighter with oil. Less restriction , cycles quicker to remove engine temperatures. We ran a mechanical gauge at motor along with electric in console during break in. The electric will spike faster than mechanical , but usually read the same at constant throttle. Heat gun reading each header tube is fastest way to see if dropped a cylinder , if you can't tell by your feel . If a motor is hurt or hurting , you should feel it.

Diggin,

You do know your holding two totally different plugs correct? Same motor?

I do believe they're the same, just one is inside a socket.

That is correct; one is inside a socket. The clean plug is from the adjacent cylinder and all the other plugs looked just like that. Fish, there is a pretty heavy film of oil on the walls of the exhaust port. The other cylinders are dark with soot. There's a big difference between the offending cylinder and the others. It could very well be something that could be fixed with a spark plug and going back to the 5W-30. But, Marine Power is making the calls and they want the engine looked at. It's their warranty so got to take their direction. One thing for certain, that cylinder was no longer firing, there's burnt oil and chunks of carbon on the plug, scoring on the cylinder walls and the exhaust port is coated in oil. Not good signs at all.

from what I read in the gm lsa breakin section is 5 w 30 is the recommended oil and also they have a piston oil spray set up as to where the hi viscosity might not let it cool them properly

I run 5w-30 Amsoil in my mostly stock LS3 and it has worked great. My observation with an oil pressure spike as described was seeing a rod bearing scar then spin blocking oil flow and raising pressure. Fellow then ran it about an hour past the spike and noticed a tapping. Some scenarios like this report a power loss but this guy had no loss of power. Be interesting to see what is learned from the tear down and if in fact rings were involved. I still don't understand why the header bolts are breaking.

This is the reason I switched from the 5W-30 recommended by GM to the 15W-50. No more, no less. BTW, the motor does not hold 10 quarts. That spec has to be either a typo or for their inboard applications. As far as the header bolts snapping, no clear answer on that but the header flange was warped. Taking it to the manufacturer to have it straightened. I spoke with and sent pictures to the bolt manufacturer and they are sending a new set. In turn, I'm sending the failed bolts back to them so they can see if there is some defect in the casting or hardening process. The header manufacturer suggested that perhaps the header bolts I'm using are too hard, causing the brittle fracture. He suggested a softer metal.

Hopefully you've learned to drive since you got the boat and haven't blown anymore boats over. Maybe you should take the money you've spent on the boat and fix the guys boat you blew over. JS

Tony, if there was a jackass smilie, I would use it but this works just as well. :tool: :knob:

You know nothing more of that event than a boat was blown over. While I feel for the guy, my conscience is clean, as well it should be. Nobody that knows the whole story would feel otherwise.

Actually everyone feels otherwise! You told the man you'd pay to fix his boat and then you dodged him like the plague. You were told to watch behind and if it was gonna lift it would be drug out of the way...instead you jump on that barge and put your retard honda goldwing headsets on and hold it to the grate and shake the rudders trying like hell to get off,never looking back. Be a man and pay for the boat you tore up! Douche!
