Drowned my poor little car today in a flash flood, now it spins freely on the starter as there is no compression.

What is the more likely, bent valves or snapped cambelt?
 
Ahh thats total garbage mate :(

Could be the belt thats snapped, but you would have to look under the hood to check it and see if the belt is rotating when cranking. If belt is snapped your looking at bent valves.

I've also seen bent/snapped rods due to this ! could be a total mess inside depending how much water was sooked up.

You mght be cheaper finding an alternative engine / upgrade rather than fixing the one you have once you have found out exactly whats happened internally.

Do you have a long arm intake?
 
I think the bottom end is ok, it spins nicely and makes no unusual sounds. Also, I am 90% sure that these engines are non-interference off VTEC, it's only if you snap the belt on VTEC you get bent valves. I could be wrong on this though. I am thinking bent valves purely from the insane pressures they would have seen as it hydrolocked.

I would get out and have a look but I have no tools with me. I think this is the justification for a B18C I have been looking for though... :D
 
Yeah B18C it mate - you wont regret it

You should still find out whats wrong with it and part out the good bits of the engine !
 
This happened to Stuarty. on here, pretty much wrecked his full engine if I remember correctly.
 
Yea I'm not holding too much hope for it.
 
My mate has an EK 1.6 non VTEC, it has a woodruff key to protect the valves. The VTEC does not have one?
 
b series defo has crank woodruff key, but is that not more for balancing the crank? how would that stop water coming in the intake and smushing everything?
 
I'm thinking it may snap in cases like this, preventing something more expensive taking the brunt?

I think Kozy is right, if the belt snaps it throws the valves out the way maybe? I don't know.. Lol
 
I'm pretty sure the woodruff key is only to align the crank pulley for the correct timing marks.

They are not a safety device for the valves in the slightest.
 
My mates timing belt snapped on his SR, the woodruff key broke and all the valves were intact. Fitted a new timing belt and ran sweet as a nut once again. Must work as a safety device?
 
That said, I don't think it will protect the valves. The valves will be fine if the belt goes and VTEC is not engaged as the valve lift isn't enough to cause P2V contact.

I think that might have just been coincidence. once that belt snaps or even the woodruff key - theres nothing keeping the engine in time = potential disaster.

Makes sense.
 
mates timing belt snapped on his dc2. nothing bent or broke put on a new timing belt and away it went again and is still going strong,dont give up hope mate lol
 
I totally believe you guys in what yous are saying about the belt snapping and no damage but can anyone 100% confirm if not in VTEC that there may be no damage caused by timing belt snapping

Thats just awesome and also something else I kind of had thought of before but never knew enough about.
