Hi all,

​​​I recently had my timing belt and water pump changed, also oil change. I was informed that the car did not start after the works had been carried out, all timing was double checked and advised ok. I was advised that a hydraulic lock was the case, and the spark plugs were drenched, so they had dried them out and seems to have solved the issue with the car not starting up. The car appears to be driving ok but only had chance to drive it for 20-30mins of mixed driving.
Anyone know if this is common issue or any other reasons that could of caused this? Why would a timing belt change cause a hydraulic lock out?
I did note that they used all 5ltrs of oil but believe these require 4.8ltrs so wouldn't think that would of caused the car not start.

I would appreciate any thoughts on the above.
​​​​​​
Many thanks

 

Did they mean hydro lock?
so water in cylinders?

 

oil change should be under 4.5ltrs in reality.........nothing you an do during a timing belt change to cause a Hydro lock??

 

Could be.
what would cause this possibility from changing a timing belt?

I read 2.0 WRX is 4.8, but correct you should check as you fill up.

 

nothing

the only way water/fluid can get into the combustion chamber is either through the intake tract, leaking injectors / seals or a head gasket issue
did they undertake any other work at the same time??

 

Yes oil and timing belt at the same time.
​​​​​​Appreciate the assistance.

 

Yes oil and timing belt at same time. The water pump also got changed part of the timing belt kit so new coolant.

Appreciate the assistance.

 

so as before nothing at all can give you a Hydro type issue??
were you there at the time or could you check with them the exact issue / description??

 

Or is it hydraulic tensioner locked and so spark plugs flooded from trying to turn over

 

So asked for further clarity, it appears it was flooded and not hydro locked, so flooded the spark plugs. But they don't know how it ended up flooded? They can't see how the hydraulic tensioner would cause it to overflood.

 

As said not one bit of that makes sense. Two hour job.

 

Agreed. Excuse my technical understanding, how would a hydraulic tensioner get locked in the first place to result in spark plugs getting flooded.

 

it can't / hasn't been...........I would suspect that maybe it hasn't been explained very well or you misheard what they stated??

 

Get them to rite you a brief report then put on here, say its for your documentation for the cars history.
