I have an oil leak somewhere and not sure why. Behind the engine where the hosing goes to the TMIC, Where the TMIC goes down into the turbo piping and BOV. Fuel/Oil mixture coming out of the BOV spraying it everywhere and haven't got a response on the tech part of the forum so hoping for better luck here. Thanks in advance

 

what!? if its in the intercooler pipes, its most likely the turbo. although i must admit, most of what you said didnt make any sense.

 

my guess is the turbo oil seals...at times where u cant explain things...take pictures....

 

lol okay sorry I was a lil tipsy when I put that up.

I have an 88 T2. When I try to boost sometimes it sounds like the turbo is choking. It starts to stutter and not accelerate, other times it boosts fine (I try not to boost at all at this point with fear of destroying something)

The top mount intercooler has two pipes that run into it. One is behind the engine by the firewall and the other is on the passenger side. The pipe on the passenger side feeds to my BOV then down to my turbo.

I have mix fluids coming out of my BOV, spraying under the hood on the passenger side. I removed the TMIC, BOV, hoses and pipes that connect all of those, cleaned them up and put them back on the car. Drove the car around and boosted a couple of times and when I got home, there was (what I assume is mixed gas/oil) an oily substance on the two pipes that connect to the TMIC, some in the BOV, and down the BOV pipe.

I'll post pictures on Wednesday .

Also, could this possibly be related to why my car does not idle? My car does not idle AT ALL. I gotta find an ohm meter to make sure the idle is set properly. Kinda scared to **** with the TPS though because i dun wanna short it out if I don't have to LoL. Welp gotta get some food then back to searching the forums for more possible answers. But if anyone has a quick answer or suggestion wonderful ^_^

 

sounds like ur turbo is going.....on top of that u might have an intake leak....

 

*nods* Any way I can check besides disassembling them?

 

**bump**

 

you pretty much have checked. theres no other way really for oil to get into the intercooler pipes. MAYBE if its all in your intake before the turbo it could be coming from the crankcase ventilator thingy on the oil filler neck, but most likely the turbo is just shot. its not likely related to the idle problem.

 

Any ideas about the idle problem? Should I just end up taking it to a *takes a deep breath* Mazda Dealer? *shivers* I feel dirty and ignorant saying that lol. No but any other ideas on the idle problems? I searched about adjusting the TPS but seems kinda eh cuz you can ruin it. If ya have any other ideas lemmie know. Thx

 

if you haven't already read this then check it out.

https://www.rx7club.com/2nd-gen-archive-72/faq-idle-problems-334730/

it lists pretty much every cause for a crappy idle and a fix for them.

regarding the oil/gas in the BOV... theres not really any way for it to get there except from the turbo, so if you can, i'd suggest picking up a cheap used-but-good stock turbo here on the forums.
