Salam every body. i have a liana 1.3 automatic and a while ago, the engine started to give knocking sound at nearly 1800 rpm, same as in manual cars when given acceleration in high gear and low speed. i took the car to many workshops including suzuki and magic motors. here is the list of things that i did.
diagnostic test with no error code, compression test resulting in 180, 160, 160, 180, cleaned throttle body, maf sensor, o2 sensor, changed plugs and plug wires, adjusted tappits (magic motors suggested they were a bit tight), used purely high octane but the knocking is not going any where.
now few friend are suggesting that i should swap the engine. what do the experts suggest here. here are are few questions in my head.
the car has 175k on clock, does it mean that engine is weak even though it doesn't consume oil?
is it the bad gear ratio of auto trany?
please help. thank you so much.
