9n3 1.6 Low Compression issue

Post by Wicked GP »

Hi, I have a VW Polo 9n3 1.6 Petrol engine. There's low compression in 3 of the 4 cylinders and a heavy misfire with the car cutting off under low revs. Would it be recommended to overhaul the engine or replace it with a another engine instead. What's the best feasible option.

The best option is to have it rebuilt with 0,50mm over pistons :)

Cost will decide which way you want to go. Rebuild will cost in the region of R15k plus.

Ending up repairing the issue, had to source replacement injectors, changed valves luckily no cracked pistons.
Car is running great again
