Hello!
As usual on my topics, I apologize for any mistakes. English is not my native language.
I found some posts similar to mine, however, I found none that reported a problem identical to mine and the doubts I have.
I have a GST 2.3 (Stroker) with an FP 68HTA
The engine was recently made by myself and I can report anything you want to know.
Recently, the car started smoking on only ONE specific occasion: after WOT, ok the peak pressure, when I take my foot off the gas, the car releases a quick cloud of smoke (which I see in the rearview mirror and can smell)
The smoke actually appears to be from burnt oil. (Wide shows rich for less than a Second, when i Hear the blowoff. I dont think this smoke os from fuel...)
The car does not burn oil when idling, neither hot nor cold, nor moving normally, neither first or second gear (1.0@boostcontrol). The only occasion is: after hard pushing, WOT, after 5000rpm .. 1.7bar .. when I release the accelerator, the cloud of smoke comes out. The cloud lasts for a second and soon after I touch up the throttle It stops.
If I want, I can continuously accelerate up to 7200rpm, with no smoke coming out. Just after taking my foot off the throttle
Everything was done: valves, guides, seals, engine block, forged pistons and rods, oem or performance parts.
The turbine oil supply comes from the head, without restrictor.
Would any of you have any suggestions? If some information is needed i can Tell you: timing (i made the map), fuel, etc
