Astra A16LET/LEL Engine Troubleshooting and Repair
In the spring of 2006 on the car Opel Meriva OPC was presented a new, modern turbo engine Z16LET, with a high specific power per liter of working volume, from what 1.6 liters he gave out as much as 180 hp. To achieve such impressive figures, the engine was equipped with a system of variable valve timing on both shafts and a small turbine KKK K03, which, due to its size, is easily inflated and from 2200 rpm you have access to all 230 Nm of torque, no dips, smooth thrust in almost the entire operating range, is not it happiness? Later the engine was strangled under the Euro-5 environmental requirements and became known as A16LET, actually it is the difference between A16LET and Z16LET, which met the requirements of Euro-4.
Power and torque are great, but it is necessary to talk about the disadvantages, and they are similar to the younger brother A14NET. A typical disadvantage of the A16LET engine, and most Opel engines, is oil leaks from under the valve cover. That is, you will be required to periodically replace the gasket and tighten the bolts.
Dieseling and clicking sounds also have a place, this is part of the work of phase shifters and injectors, it is normal and there is nothing wrong here.
Shorking sounds of air conditioner compressor are present and continue to frighten owners, motor vibrations are also not lagging behind and make themselves known.
The motor itself is good, momentary and at quiet driving economical, but according to reviews does not quite correspond to its 180 h.p., there are cases of pistons collapse and cap repair at mileages up to 100.000 km, increased oil consumption and detonation are the first symptoms of approaching overhaul.
In addition to the usual LET version, there are its sport and de-fortified version. Sport engine A16LER develops 192 hp and is installed on Opel Corsa OPC, differs from the usual A16LET by intake and firmware. The deformed version – A16LEL, with an output of 150 hp, is put on the civilian version of the Opel Corsa D hatchback. With one or the other engine, the small Corsa goes very fast and quite dynamic.
In general, the engine A16LET(Z16LET) is not bad, if you pour good oil and monitor its level, pour quality gasoline, not too much racing, there will be no problems and the motor will serve you for a long time.
In 2012, Opel released a replacement for this motor, in the form of A16XHT, a very modern, even more torque and in general, more perfect engine.
Tuning the engine Opel A16LET/LEL
Chip tuning Opel Astra 1.6 turbo
We turn to any adequate tuning office, order a firmware and get about 210 hp, is it enough? No? We go further, change the whole exhaust on a straight-through pipe 63 mm (there is no sense to put more, not that power), get a cooler-kit for Astra 1.6, flash and get about 230 hp.
Of course, it is possible to screw KKK K04 from Astra J OPC or Garrett 28, to put forged pistons, to adjust and to blow on all money, but then it is necessary to think about gearbox, a suspension, brakes i.e. it will be necessary modification as a whole, it is expensive and not rational, it is easier to get initially fast Astra OPC and to modify it.
