While the engine is out, you should absolutely do the preventive maintenance stuff that is usually hard to do with the engine in. Spark plugs, belts, checking the timing chain/belts, etc. It might be worth the extra cash to pull the heads and look directly at the pistons, maybe pull the oil pan. You don't know what those 40,000 miles were like on that engine. And let's face it: That engine was cheap for a reason. I mean, pretty much, if the engine is out, might as well pull at least the big parts off and make sure they're healthy. It would suck to find out in 50 more miles that a piston ring was broken or a valve was cupped, when the extra $500 it takes to pull both heads and the oil pan off would make quick work of identifying and fixing an issue that could grenade the engine again.
I called it. It was run with water in the oil. Likely before you got it. Damage was done to a couple of rod bearings. After 50 miles the bearing gave out, seized and spun the bearing. And the connecting rods knocked the sides off the block. The heads likely fine. Great buy on the replacement engine assuming it was good when that car died.
Maybe you shouldn't have run the engine before an oil change. Of course, I could be wrong about that, but proper lubrication is extremely important to performance engines. Ask your mechanic if running it like you did may have contributed to the carnage.
Cool mechanic, totally dig that guy. Knows his stuff, gets stuff done, and doesn’t break your balls. My understanding of chemistry and physics leads me to believe the engine grenaded it’s from very small amounts of rust developing on critical surfaces inside the engine while sitting, after the flood water penetrated it. Flushing the water out doesn’t address that issue, only prevents the pistons from compressing the incompressible. Glad you got a swap so fast and so cheep. Congrats.
Had a similar issue with an s10 a friend of mine had. Was a 4.3 v6. Long story short intake gaskets blew interally. Peanut butter for oil... We flushed it. Seemed fine. New gaskets and going down the road engine locked up. Had great power, oil pressure, everything was normal then sudden it locked up solid. Only thing I can guess is there was some gunk after all that lodged in the crank oil galley. Couple heat cycles broke it loose, plugged oiling to the rear rod bearing journal as thats the one that ended up spinning and welding itself to the crank. I noticed it appears that it was the rear cylinder on your engine too that had the issue.
My neighbor has a yellow Granturismo. He loves it and gets it serviced regularly so it's held up so far. I don't remember what year it is though. Also that Aston Martin One-77 in the background is really awesome.
Would 100% be the damage from hydro locking the engine when started with water in it. Water doesn’t compress like air so it bends rods on the compression stroke. Bent/damaged rods equals Rodney out the side of the block.
Y'know, despite the unforeseen engine bomb, I still think you guys got a pretty nice deal on this car. I love my GranTurismo, and I was broken hearted when I heard your engine went. Glad you could get a replacement for so reasonable a price.
I think on your next flood car have Corey pull the oil pan and check the crank and the rods for issues. That will give you confidence and save you dollars down the road. PLUS - do not drive the car until the fluids have been changed. I was cringing watching you guys start and rev the engine when it came off the trailer.
It's obvious the original engine was run with water still in the oil. Forget the engine for now, I would be more concerned about water damage to the rest of the drivetrain and all the complex electronics.. especially the electronics that control critical safety components. It may run fine for a while but eventually small things will start to pop out. good luck
There will be most rust related issues on this car long term or even short term. If it was submerged in water, the water also got into the drive terrain and axles and the bearings are going to rust and start making all sorts of grinding noises more likely than not. Flood cars are just a no no. Good luck
the holes in the block accrue when the rod is.still swinging with out a piston still attached so the rod swings and punchs a hole in the block , id assume the wrist pin bearing failed
Just did the oil change on my bosses granturismo and I couldnt beleive it took 10 quarts of oil. Ive never had oil come out of the drain with such force. It hit the pan and bounced straight out all over the floor, then my face when I tried adjusting the drain pan! What a mess! I'll leave the dipstick and filler cap on next time!
Yep there you have the Bill of starting a car with alot of water in the oil in the first épisode. And maybe having still water in the cillinders so Fried the bottom end
What's Happened to the 911 LS swap or have I missed something, you haven't even mentioned it and we haven't seen it. Was that a boxster or a 911 996 RS
All I know is that Maserati in Europe is called "The mechanic's dream", what means that all Maseratis pass more time with the mechanics then on the road and mechanics can make big bucks on it.
"Felt bad after I explained the situation and knocked off $1000 bucks." I'd wager it had something more to do with the opportunity to get a plug for the shop on RU-vid, but that works.
