Oil smoke on start up on Reman/New engine
 

On remans or new engines. Oil smoke at cold start. A bit after hard engine breaking...a bit on WOT.

brand new turbo in my case that isn't leaking. Definintely the engine in some way.

I'm trying to get an idea of how common this internal oil seal seapage is when the engine is cold and how long it normally takes to make the seals...seat and seal.

I don't want to yank out the engine if I don't have to. Ray at Malloy is taking good care of me and will swap it out if need be...but I don't want to have to mess with it if the seals are going to seat pretty soon...I just want to know how long its gonna have to look like a beater at cold start up. Its getting annoying.

the car is burning more than a quart in less than 1000 miles.

thanks

Some oil smoke on cold starts is normal anyway. The injectors are squirting more fuel on the warm-up enrichment map, and due to the extra fuel injected, there is extra oil injected, as well.



Or I could be wrong.

I've tried my best to datalogit the voltages to the OMP at start up, but all i've seen is a straight line...no major "dump" of oil at start up.

I've installed Pineapple motors and remans. Usually ALL rotaries smoke some on COLD start. I test drove a NEW 88 GXL with a couple hundred miles on it, it smoked on start-up also.

I recently went through the same ordeal that you describe. On cold starts of a "new" Mazda remaned motor I experienced a blue cloud of smoke out the exhaust that lasted several seconds and then subsided. After living with the problem several months and trying several things including new turbos, I and my Mazda mechanic concluded that it was a bad internal seal, probably the inner most O-ring seal on one of the rotors. I pressed Mazda under the warranty and received a new reman motor. No more blue cloud on start up. You may be experiencing the same problem. Good ol' Mazda remans!

dangit...I don't really want to deal with the oil smoke...

the car without reman didn't smoke.

I had a theory too about the oil injectors dripping out whatever oil they had in them instead of holding it in...this is just based on my recollection that the new reman came with a tag saying the new oil injectors were some "new" "different" kind

i'm just wildly theorizing now :)
