A bit of an update......
Cleaned out PCV and drained a little oil from sump( was a bit overfilled) and the problem has become significantly better.
Still there though.
My engine doesnt burn a lot of oil. Maybe half a litre of mobil 1 in 7500km.
Just have the deceleration blue smoke issue.
I do a lot of highway driving running around 130km/h.
Will check PCV this weekend and see if anything changes.
Yes the seals where replaced, along with every wear item on this motor, except the guides. Hence my frustration here.
Surely though after 25 000 km, the rings should have seated by now? Or does this motor need longer?
Yes, overrun I mean coasting down a long hill or deceleration.
Rings and pistons are brand new, from Toyota, and don't have any symptoms on acceleration and pulling 21-22 inches on vacuum gauge.
Thank you, will stick a camera down the ports to check them
Hi
Its been a while since I have posted here.
Rebuilt my 1fz engine last year, all has been well, already put 25k km on it with no issues until now.
I am getting blue exhaust smoke when coasting downhill in gear, and a little on cold starting first thing in the morning.
The only thing I have...

With regards to the nipples by the mixture screw. The single one is blocked off. Where there are two (one above the other) top nipple is vacuum advance and goes to dizzy the bottom one goes to charcoal canister
Look into the carburetor 1fz head, when I pulled mine ( and like an idiot, forgot to take pics so cant reference back) the chambers looked like your gen2. This was to lower CR for bad fuel I suspect.
And has a dizzy hole. Just block off hole for mech fuel pump.
Hello All
Does anyone have the part number for the ARP bolt set for the main bearing caps for the 1fz motor. Trying to order them but everyone asks for part number.
