Did a compression test just then aswell, compression came up fine
As far as I’m aware and was shown by one of the best and recognized turbo builders around Kyp from advance turbo performance all garret turbos have a oil restrictor within the core chamber which is a brass fitting with a hole the size of a pin prick which regulates how much oil goes into the turbo. I believe your problem lies either in your oil drain not draining effectively enough, or the seals on your turbo are shot ( very possible considering it’s a 2nd hand turbo) iv seen seals go on turbos which are brand new, iv seen seals last for ever, and iv also seen bad oil drains cause turbos to go bad. When I mean bad I mean burn oil / produce smoke. Remember typically you will not notice oil levels drop as it takes a very very small amount of oil to burn and produce a large amount of smoke.
Also recognizing blue / white smoke can be very hard especially during the day oil smoke is white smoke with a blue tinge, remember also when you take your foot off the accelerator it takes a few seconds before you see the smoke out of the exhaust, especially if the car isn’t under load this kinda smoke is very typical of a turbo burning oil.
The other possibility is burning oil from the valve guides / stem seals but I personally have my money on it being a turbo problem

Seals are gone, dropped the oil return off the sump into a container and it still pumped out smoke.
Its only happened since I bashed out the insides of the cat (for testing purposes only :)) so that would prove your point that you made earlier about the Honda cat being very good at hiding smoke.
I've also seen smoke showing up when you lift off the throttle as being a valve seal issue.
Actually just thinking about it..
Wouldnt the turbo still throw out a lot of smoke in boost? Why is it that only when I lift off the throttle a whole lot of smoke poors out? Valve seal issue like you just said saxman? :)
friend of mine with a jrsc b16 had the exact problem. Whenever he'd lift off the throttle after getting on it hard, it'd billow smoke out the back. Same with someone else I know with a turbo b16. Valve seals both times. Vacuum from suddenly shutting the throttle body + bad selas = no fun.
how is your PCV system set up?Quote:

i highly doubt ur stem seals are gone. i do agree its a turbo issue, and cats do hide alot of smoke.
did you get a leak down test doen when you had the compression test done?
Chances are your valve seals wouldn't just go unless there was a bit of a preexisting problem. i.e. it was starting to go, the cat was hiding it, changing the cat showed it.
I'd sort out the turbo issue, then go from there.
Spoke to Dyno Dave, seems to be a turbo issue, all good :)
dyno dave is a god
