Hi All,
I am from the UK and own a 2014 ST180. I recently had an engine health check (at 59k miles) and found a cracked liner on cylinder 3. The compression test was normal with 182 psi in each cylinder. It also passed the smoke test, CO2 header tank test and no other faults were logged. The car drives perfectly with no coolant loss or white smoke. I have noticed a 1 second drop in boost under low load when car is cold (like a hesitation) but otherwise all is fine.
I actually have a stage 1 intercooler, 3inch scorpion cat back exhaust and ITG intake fitted for the last 6k miles. The car has a stock map and was never remapped in the past. My plan was to go for a stage 1 or 2 remap, however, the cracked liner will prevent me from doing this as I may risk causing the crack to worsen.
I plan to keep the car long term and wanted to ask what my options are. I was thinking of a bottom end rebuild with Westwood cylinder liners (or something similar), as this would hopefully strengthen the block and prevent any future issues. Do you have any opinions on this approach?
The other option is to buy a good used engine to swap with mine, but there is a possibility that this could crack again in the future.
