Honda D16 engine characteristics

Honda Civic D16A engine faults and repair ( B, V, W, Y, Z )

Honda D16The engine D16 (hereinafter D16A, because it is the most mass representative of the series) is part of the family of engines Honda D (D12, D13, D14, D15, D17) and is the same as 1.5 liter D15, which increased the stroke of the piston from 84.5 mm to 90 mm, the height of the cylinder block, respectively, has grown to 212 mm (on D15B 207.5 mm). The cylinder heads are both twin-shaft DOHC and single-shaft SOHC, as on the D15B. Otherwise, the same engine, on an aluminum cylinder block, with a timing belt (replacement of the timing belt every 100.000 km), without hydrocompensators (valve adjustment on D16A is carried out every 40.000 km), the average life of such a motor about 300.000 km.

The weak points of the D16, faults and their causes

1. Crankshaft pulley. Crankshaft pulleys often break on the D16, the problem is solved, depending on how it happened, from pulley replacement to crankshaft replacement.
2. Swimming revs. The phenomenon is not frequent, but it happens, the typical cause is a dirty throttle and idle sensor (valve). Cleaning will save, if it does not help, look oxygen sensor (lambda probe).
3. Exhaust manifold. Diesel sound on D16 is a sign of a crack in the exhaust manifold, check. Welding will not save, will burst next to it, look for a contract manifold or alternatives.

In addition, on D16 often die tramblers, the engine starts to twitch, all sorts of dull, refuse to start and so on. Lambda probes are not too durable, the oil pressure sensor can occasionally leak, in principle, the engine itself has no significant disadvantages and with proper maintenance, reliable as a hammer, and the bulk of the problems associated with the age of the motor. Resource D16 is decent, up to 250 thousand kilometers of problems should not be, pour good oil and will work long and trouble-free.

Tuning the engine Honda D16A ( B, V, W, Y, Z )

Atmospheric. Turbine

The D16A is not much different from the D15B when it comes to tuning, there are sport camshafts for D motors, compressor kits, turbo kits, you name it, on the market
