Previously, Sergey had a “nine”, so decrepit that it simply drove the cheekbones out of a desire to buy a foreign car! Our hero clearly formulated the task: Toyota Avensis, station wagon, 1.8 liter engine, mileage of 150 thousand, price not exceeding 18 thousand dollars … "
The search for the car dragged on, and suddenly - good luck! It turned out that a friend is holding an office for the sale of used cars from Germany. Two months later, Avensis was delivered to Moscow in 2001 with a mileage of 118 thousand km for $ 17, 500. When meeting a fresh, clean car, the lucky dancer danced with happiness.
A fabulous life has begun: Toyota flies a swallow. But once in a sharp turn the oil pressure lamp blinked. I had to remember how the hood opens. The owner took out the dipstick … but there is no oil!
With a heavy heart, Sergei went to the company diagnostic center. The verdict was harsh: “The motor has worked out a resource, boring is not provided. We can replace the complete cylinder block - 95 thousand rubles, 180 thousand will come out with work. Please note, the new engine is even more expensive! ”
Not wanting to get into debt, Sergey decided to look for alternative solutions - so Toyota got to us. By the way, the mentioned prices are real: the second-hand is good without surcharges, while the Avensis is really not a nine in repair! For expensive cars from the secondary market, the service does not make discounts. The owner recalled how the "merchants" promised him five years of bliss. Cheated?
To admit, and we admired the new-looking Toyota. But … there were some doubts. For example, in six years the station wagon allegedly covered only 118 thousand km, and Europeans most often use them in small business, rolling 40-50 thousand per year! But according to the order-orders of the German service, it turned out that the mileage was indeed nonsense. So, the previous owner managed to kill the car! Or resellers - forge documents.
So, here it is, the 1.8-liter Toyota Avensis 1ZZ-EE engine. Checked the compression. In three cylinders - 12 kgf / cm2, in the first - 8! They dripped oil - it grew to almost 15 kgf / cm2. Clearly, the problem is with the piston rings. Are you coked? Sergei swore: they filled, they say, good gasoline at the same gas station. Nevertheless, we tried to use a raskoksovyvatel. Compression increased to 13-14 kgf / cm2. The owner left, but after a week he had to disassemble the motor - the oil consumption did not decrease.
They removed the valve cover: inside, solid oil deposits. Pistons removed. Compression rings are alive - hence a good compression, but a couple of oil scraper “fried” tightly. Former owners poured crappy oil or did not change it for too long.
But the Toyota is even true to itself here - the breed! Some engine components were not affected at all. Crankshaft journals are within tolerances, but liners and half rings are better to replace - there are scuffs, risks. The cylinder head is in order, even the gaps did not need to be regulated (the timing is reliable here, without hydraulic compensators - it is not for nothing that owners praise it).
But the piston-cylinder group needs help. Although there are still remains of a plateau-honing mesh, the cylinder diameters increased by 0.02 mm (with a maximum tolerance of 0.013 mm), the pistons lost 0.02 mm - the mounting gap was 0.085 mm with a maximum allowable 0.1 mm. If you put in new pistons, you get 0.065 mm at a nominal value of 0.058 mm. Too much! After consulting with the owner, they handed over the cylinder block for repair to a specialized company - it turned out that this engine still has a reserve (from the point of view of Russian repairmen) for boring the block to a repair size.
Here I allow myself a small digression. Modern engines of a number of leading companies are not subject to overhaul, as owners of "advanced" foreign cars know firsthand. Russian operating conditions now and then put people in front of the need to pay for other people's disgraces with fuels and oils, or, more simply, for someone's theft. You can screw up an expensive motor in one trip - and then what? The company will gladly replace the motor with a new one, but for the money of the “culprit” - the owner of the car. At worst, it will offer to change the cylinder block complete with a crankshaft, connecting rods, pistons, etc. Even this will cost a lot of money.
Subcontractors soon became interested in a new ideology in engine building - firms such as Mahle, KS, AE, Elring Victor, Reinz, Autowelt, Goetze. In essence, their efforts made the motors repairable. The technologies of block boring, sleeving have been developed, the production of most spare parts for the most popular engines Toyota, Audi, BMW, Volkswagen and others has been organized. These non-original (and relatively inexpensive) parts and assemblies are delivered to specialized countries for engine repair to different countries . Among our customers are our Russian companies that have accumulated vast experience. In the described case, the answer was quite definite: cast iron sleeves of the 1ZZ-EE engine block can be bored and honed under the pistons of Autowelt's diameter increased by 0.5 mm. Thanks to this, all the work together with spare parts cost Sergey 50 thousand rubles, and the engine received a second life, and the client received a guarantee from the repair company (one year or 20 thousand km). Of course, barely buying a car, it is a pity to spend another two thousand dollars. But in a different way repair would have cost almost four times as much!
It looked like the guide surface of the piston skirt. The light oval mark 1 is the regular place for checking the diameter during wear control. Highly visible traces of machining 2 and a separate pronounced nadir 3 are visible above, which indicates insufficient lubrication of the rubbing pair at high loadsDeposits on non-working surfaces of the piston, reminiscent of a dense varnish, indicate prolonged operation on low-grade oil. The compression rings 1 still retain their mobility and provide an acceptable piston seal in the cylinder, while the oil scraper 2 burned n.
