Having problems with your Toyota Yaris ?

I have had a 120,000 service on my 2005 Yaris. Piston checked revealed cycl 1 175 PSI cyl 2 150 PSI cyl 3 120 PSI and cyl 4 110 PSI -supect fault to piston rings - recommend taking out the engine etc quoted $2,200 - I am shocked at the cost - I dont have any problems with the car - is that a common fault - can I let it go as the car seems to run well?

Answers :

The 175 and 150 readings accpetible the 120 and 110 are low. Are you burning oil .All of these readings should be with in 15%of each other .And 120,000 is not a lot of miles for for this vehicle the rings would not be the first thing i would think of although there is something wrong here. I would look at valve problems or head gasket possabaly See what the spark plugs look like on the two high cylinders and compare them to the two low cylinders make sure they worn't loose the plugs should be kind of a tan color if the engine is running good if there black and wet then there is a problem. Honstly something dosn't sound right here if the vehicle was running OK and you brought it in for service and then your told you need to rebuild your engine. Check the plugs and mabey have a differant mechinac look at it good luck
I say as long as it runs ok and there are no codes coming up that set off the check engine lite, just keep driving.
