automotive

05/02/2009 6:16 AM

Yesterday one of the workers ran his new dodge pickup ( 4.7 automatic) through too much water and injested enough that we had to remove the plugs and roll over the starter to get it pumped out , I changed the oil which also had water in it . Now I put the plugs back in and cannot get the motor to turn over .Then I changed the starter as it acted like it was slipping (new one acts the same way) Big Question did it wash off the oil so well that the starter can't crank with compression or what HELP!

Good thing it didn't start. Drain the trans/case, that probably has water in it too. You,ve got water everywhere. I,m just a poor sod that this happened to. Give it to the dealer or a competant mechanic to fix.

REPORT----Well this is the damages to the vehicle. $ 5500.00 at the dealership for a short block as there is no compression on one cyl. This was not fun,I bet this employee doesn't run thru big puddles again. One poor design thing is that the intake inlet is about mid grill which was just right to suck up the water, if it was 8-10- up it would have missed it ,but I guess puddle height plays into the equasion. Should I fire him?, Oh the one comment about it's only a DODGE was not apreciated For 20 years I have had good use out of them, just take care of what you drive Thanks to everyone else who responded you were a big help

There is a very high probability the engine has bent connecting rods and broken pistons. It is most likely a 'remove and replace with new' case.

The repairs would normally be covered under the 'comprehensive' insurance coverage for the vehicle.

Water in the oil would not wash off the lubricating oil film.If a significant time passed with the plugs out, the piston rings may have stuck to the cylinder walls from corrosion. Try adding a tablespoon of Marvel Mystery Oil to each cylinder, let it sit an hour and crank without the spark plugs to distribute the lube.

After letting the mystery oil or soluble oil set awhile with plugs in loose. When ready remove the plugs and try to turn the engine over by grasping the serpentine belt or use the bolt holding the harmonic balancer onto the crankshaft at the front of the engine.

There may be water on the pistons in the cylinders and as is not compressible, the engine would not rotate with the starter. I would remove all the plugs and see if the starter is able to rotate the engine and if water comes out of the plug holes. If so, rotate the engine more till all the water comes out, clean the plugs and dry the wires and try starting the engine. It might work Good Luck

OK, what you need to do is first pull the plugs and check if you have compression on the cylinders. If you can't get the motor to turn over fast enough to do this, you can do a leakdown test on each cylinder to see if they will hold pressure.

If they don't, squirt a small amount of light oil in each cylinder, turn over to distribute and try again.

If available, you can use a borescope to inspect down into the cylinders to see if there is any obvious damage.

Define what you mean by "slipping"; is the starter motor turning over really slow, or fast? You say the replacement is doing the same thing, so the odds are that was not your problem. Does the engine turn over really slow, or fast?

If you verify good compression, and there appears to be no physical damage to the engine, you need to check all the basics (ignition, ECM inputs/outputs, fuel delivery/control, and so forth). Also, you will need to verify electrical grounds and supply side circuit inputs. Relays/switches can be damaged, causing no starts. You will also need to verify a clean supply of fuel to the engine.

And, if you can get in running, you should check ALL the fluids in the vehicle for water comtamination as well.

Let us know what you find.

This is an excellent point: if the engine is spinning over at higher-than-normal speed, it could mean that it has no compression. If it actually ingested water, there are at least three possibilities that come to mind for why: first, water being incompressible, the engine may have stopped very suddenly and caused the timing belt or chain to jump a tooth or more - or even break the belt. Check basic timing. Second, if it kept on going around, it may have bent valves - you MIGHT have more clatter in the valve train than normal, if so. Third, ingesting water can actually knock the tops out of pistons. USUALLY, you'd "only" lose one or two, though, and the engine would start on the remaining ones, with a terrible miss, and likely oil smoke from crankcase venitlation.

Well if you got water in the cylinders and after you removed the plugs and spun it over, you should have filled the cylinders withe w-D40 and the some mystry oil and agian spun it over. Could be that there already is rust forming on the cylinder walls. You need to spray down the cylinders with penetrating oil of some sort, then manually spin the engine over to get it freed up then again apply mystry oil toe cylinders to get them well lubed up. I think once you do that it should spin over with the starter.

The other thing is when you do get it running your going to need to change out the oil and filter a couple of more times inorder to get all the water out of the block.

Good luck,

Brian
