#1 of 119 Scion Xb Engine Problems
Jun 30, 2006 (8:47 pm)
I was wondering if any one else has had a Scion xb engine problem. I took my scion to a scin dealer and the told me i blew my engine because it hydro locked due to water enter the intake through a custom installed intake. When I took the engine to another mechanic, three of them, They told me that there was no way that water caused my engine to seize up and blow a rod. Has anyone else had this problem?

Did you drive in water with that custom intake? A couple of people on ScionLife hydrolocked their engines by driving through flood water or deep puddles. They both had cold air intakes located low behind the foglight. One person's engine kept running, but made a ticking sound, which was diagnosed as a bent valve. He must have just gotten a little bit of water in there. Usually a rod breaks as soon as the incompressible water gets into a cylinder.

Yes a big puddle. but i have had my engine looked at by three mechenics and they said there was no way that water was to blame.

Low cold air intake + big puddle = hydrolocked engine. Yours is the third case I have heard of just reading Scion forums for three months. Maybe there have been a hundered hydrolock cases presented to Scion for warranty claims over the past three years. It may be hard show the broken con rod was Scion's fault. They are impossible to break without water in the cylinder.

Are the rods bent or no?

In the first post the owner said: "They told me that there was no way that water caused my engine to seize up and blow a rod."
I guess "blow" could mean either bend or break. But I think it would only happen to one rod and not progress to more than that. In a hydrolock, the engine stops instantly. The owner called it "seizing", but seizing is a completely different problem.

Yes I only Blew One cylinder. The engine kept running until it ran out off oil and i can to a stop on the side of the interstate. My mechenic said that when he released the one bad cylinder the engine still ran. I mean it would turn over but wouldn't stay started. It did not seixe the whole engine up.

Your auto insurance may cover the damage. Scion (Toyota) is not responsible to warranty the damage to your engine caused by modifications to air intake you made.
Hydrolock due to stock or aftermarket intake is not limited to Scion, this is a known problem with many makes of vehicles when aftermarket intakes are added, and some stock vehicles with a low intake are known for this issue when drivers do not use reasonable caution and drive thru water.
