I changed all the hoses. Especially the one which goes from the oil filter to the back of the block. That one kena kembang kow kow because my engine oil leak and the oil soften and expanded the hose. I had 2 leaks and decided to change all lah. Once in 14years ok what.
Itz need for my GTT (Auto), the original one has broken, and i replace with the manual version(Denso map sensor), power cut at every 4k rpm due to this issue, i have found few halfcut but they are not willing to sell...
