Diagnose my rx7 13bt fd !
 

Okay recently there has been a lead up of events causing its resting place untill sorted,

to start off, I Have a 92 rx7 13B extended port, single turbo converson, 48MM masterpower wastegate plumbed back in, medium size front mount, ssqv bov ..

The engines done 25 Thou since rebuild

when i had bought it, it was smoking on deaccaleration "used as a bargining point dropped price 4 thou" but he was trying to tell me its done that the whole time because of the single turbo conversion, twin oil lines joined to one

so it blew white/ lighty blue smoke when deaccalerating for 6 months so far then one day i noticed a boost leak, went from 12psi to 7 psi sounds like it was under the inlet manifold

so oil had been slowly spraying out the bov to cover the bonnet in oil , i notcied my oil coolers where smoking aswell and that there is smoke comming from around the turbo real light ...

with all that happening i still took it out for a drive then after i sat there idling my temp gauge went up, i think there is not any water going through the bottom of the radiator, im now not driving it with the risk of overheating,

Got any pics of the "twin oil lines joined to one"?

It could very well by an oiling problem to the turbo. Oftentimes the oil lines require some sort of restrictor but not sure if the symptom for that is smoke on deceleration or all the time.

he suggested to get a restricter on the oil feed lines, he told me they joined together "somewere" maybe one was blocked causing more pressure on the other ? i have a startup vid of it before the radiator became blocked? water pump fail?

Lets say i leave it idling on warmup "before radiator problem" i could notice smoke comming from the turbo area and out of the headlights from the oil coolers , what could be causing that
