Toyota Day

Although the Corolla had recently been to the mechanic changing the shocks, I took it to the Toyota Day for a Check-Up.

With 190428km on the clock these were the remarks made: 

- parking brake lever in need of adjustment;

- minor engine oil leak;

- floor mats in bad shape;

- battery in end of life;

The brake lever is fine the way it is for me. 

The oil leak is due to the oil washer from last oil service, it had to be replaced since the ones they use are plastic instead of cooper, and it got "twisted" allowing some oil leak.

The floor mat on the drivers side is in a rather advanced state of degradation... something to think of in the future, since it does interfere with the driving.

About the battery... its been there for almost five years (since I bought the car) and have no idea of how long its been there before, that will probably be my next step, before it leaves me stranded.

New shocks

After been driven by over 190 thousand kilometres, the right from shock was knocking when turning left and when driving on badly paved roads. It could only be the shocks the origin of the noises since there seemed to be no apparent wear in any other suspension/steering components, so, new shocks were bought (Kayaba Excel-G) to retire the OEM ones.

Although the rear shocks were still capable of keeping up to the job for some more time, the ones in the front end were in pretty bad shape, the right front one had some very noticeable wear in the piston (hence the noise), opted for replacing all four shocks at this time, with the respective bushings.

The four shocks and bushings costed me 245.51€... and driving silence settled in again.

The spare key adventure.

Had to use the spare ignition key since the usual one was some 30km away from my location. The engine did crank but it just wouldn't start, it seemed that the car immobilizer didn't recognized the spare key. I had a car, I had a key for that car, but what I really had, at that moment, was a very big paperweight.

Had someone pick me up to get my usual key and the engine started just fine, paid a visit to the dealer the next day to get the spare one recoded, 32.35€ and a hour later, the key was back in order and with also a new battery fitted.

Valve clearance check: take III

Having reached the break even point, and since in the last service there was no time to measure de valve clearances, today I drove the Corolla to the workshop, let it cool down for three hours and got to work.

The 3ZZ engine ran over 55400km on LPG and 44320km after the last measurement, the present valve clearances are as follows:

- intake valves: from 0.15 to 0.25mm, measured value 0.25mm

- exhaust valves: from 0.25 to 0.35, measured value 0.30mm

The 0.25mm feeler gauge in the intake valves was quite hard to fit between the tappet and the cam lobe, the 0.35mm didn't fit in the tappet clearance in the exhaust valves, and the 0.30mm had some noticeable clearance left (compared to the 0.25 in the intake valves).

All clearances in the intake were similar, as were the clearances in the exhaust ones, there are no wild values in valves with the same function.

Next measurement in 50 thousand kilometres... with the replacement of the rocker cover gasket, it leaks a very small amount of oil near the second cylinder spark plug.

Break even point

After running for 55358km over two years, seven months and seventeen days after the installation of the Vialle LPi LPG liquid injection system, the Corolla got to the point where the cumulative value of the fuel savings surpassed the value paid for the installation (2337€).

It took longer than expected to reach the break even point, this was due to the increase in LPG taxes and last years petrol price drop. 

Even with a average LPG consumption of 7.77 litres for 100km, which represents an increase of 24.1% in fuel consumption over the values registered in the Board Computer, the fuel expenses dropped 43.8%.

Next landmark... when it reaches twice the installation value.

183k service

The running distance keeps adding up and another service was due one year after the last one. 

This time, besides the oil (5W30 as recommended by Toyota), oil filter, air filter and cabin filter, the Corolla had the auxiliary belt and the front brake pads replaced, none of which had been replaced since I own the car. The replaced brake pads lasted for 93 thousand kilometres, more than half of the Corolla's total driven distance, 183369km.

Also the clutch actuator was lubricated because, when lifting the foot front the clutch pedal, it made a squeaking noise... again.

Total expense was 71.04€ and it is ready for 15k more, soon valve clearance will be measured.
