guys, I had my set of oil cooler with pipes and 1 adaptor (aka sandwich). Upon installing, i was told that one adaptor is not enough to avoid a blockage at the oil filter area on my ek4. Need to have another adaptor to stack the thickness to avoid.
For those who install oil cooler before on ek4, did u guys use 2 stack adaptor to avoid a blockage located at oil filter area? Is there anyone using just one layer? Problem with mine after installing is leakage in between the 2 adaptors Worst it drip on my exhaust pipe. Bloody stink! Need experienced advise from senior, please help.
