hi guys, this issue has been happening more frequently over the past 2 months or so. i use to get the pop after trying to start before on cold days but it never gave a puff of smoke.
basically on cold start up or even after i stop driving and trying to start again after 30mins-2hrs, it is very hard to start.
it would crank, and feel like its going to start then it would pop and will not start, so i'd have to crank again and keep holding it and then it would start after sounding like a struggle, then a puff of white smoke would come out.
after googling, and doing some searching on here, it could either be leaking injectors or valve stem seals.
after about ~1.5years since the rebuild, i noticed there were some dirt residue around the injectors which i assume they were leaking an dirt has stuck to it. i do notice around the base of the injector where it sits in the plenum its wet, but it doesn't drip out fuel, is this normal?
anyone have an idea what it could be?
engine: rebuilt rb25det neo
ecu: haltech PS1000
injectors: hiflow standard injectors 600cc
any help much appreciated.
