oil around the cold side flange on the intercooler

I've already decided I'm probably not going to make any claims on the power train. if something goes wrong, I'll just replace it with something better. they can't void the warranty on the radio for having a front mount, so I think I'll still be ok with the stuff I don't want to mess with.

Yeah i hear that but if your oil pan cracks a FM isnt the best think to have on the car when you bring it in lol...

if the oil pan cracks I'll buy a new one and put it on. no biggie.

the only thing that would suck is if I cracked the block, but with meager boost and no nitrous or anything dangerous, I don't think that will be an issue.

I guess i just dont see the need to buy covered parts when i can just put a few stock pats back on and bring it in. Then again its prob better then going through all the s*** they put ppl through like having your car for 2 weeks because an IAC motor went, when i could have spent $60 and done it myself...lol
 
yeah that's the way I see it. I have enough done to my car already that I'd rather just do the work than put it back to stock and reinstall everything. plus the more you take things off and put them on, the worse the seals and bushings and such wear. also, I love spending quality time with my car.
 
if oil is comming out of those holes, they must go all the way into the IC. if it goes all the way through the flange like you said, thats where the holes will end up, inside the cold side end tank. and if oil is comming out, i gaurantee air is leaking too. it is very possible to have a leak and not see it on a gauge. a slight trickle of air at 18+psi......you would have no clue. air is obviously less dense than oil, so if the thicker oil comes out....the air comes out even easier. none the less the RTV should handle it.
 
Put new Ic on, cold side, some oil on old Ic also a bit of what looks to be weepage at flex connect on mscai but have added no oil. Interesting topic
 
ok I reread it 5 more times and I have gleaned that ericrapp put a new intercooler on and he spotted some oil collecting in the old one when he took it off? that is incredibly difficult to understand.

I'm sorry about that. yes as others have noticed, when replacing Top Mounted Intercooler TMIC I noticed a small amount of oil on the hot side ( inlet ). I also noticed with my Mazdaspeed Cold Air Intake ( mscai ) at the flexible connection a residue around the clamping from the rubber flex fitting and the polished tube than leads to the filter element. I am not concerned with this . I beleive it to be related to the Pcv Valve. I promise to slow down with my attempt to communicate! Thanks for bringing this to my attention!
 
haha sorry, it really took me a couple of times reading before I got it. no offence.

anyway, I am thinking it's the PCV hose also, I guess I will start researching a nice catch can to put in the loop. I am sure that will solve the problem.
 
catch cans are tricky. if placed in line with the PCV valve and intake manifold it will only collect oil under vac.
the air gets drawn in from the breather through the crankcase and pics up oil in the process. from there into the catch can to collect the oil, and then into the manifold with clean air. but then when boost comes in, the pressure comes out of the manifold and into the catch can BEFORE the pcv valve. the PCV is supposed to stop the air flow, but it is very clear (oil in your IC) it doesnt. once boost leaks into the crankcase it can force air/oil out of the breather port. the best way thing to do is to put the can in the same place buy add a check valve between the manifold and the catch can. the check valve works like the PCV valve should. it will allow air to be drawn into the manifold under vac. but under boost it will seal and not allow air past. this will prevent possible leaks from your catch can from the pressure that would otherwise be present, and stop any boosted air from leaking past the PCV causing blow by getting into the intake tube/IC. just my thoughts. thats how my install will be.

I'll need to digest your thoughts, Tru. Is this a bad thing occuring or an inconvenience? Thank you 3, I look forward to the information that you dig up! Boost in crankcase? I'm going to have questions I'll bet.
 
it is a bad thing IMO. it can lead to exhaust smoke if too much oil gets in the manifold under vac. and it can clog up your IC with oil if it gets past the PCV when under boost. the catch can + air check valve is the way to go. that seems to be the best method on the SRT's. or i suppose you could run 2 cans....one on each side of the crankcase. thats just too much clutter and $$$ IMO though.
 
the only ways that oil get into your ic plumbing is from blow-by. that is the turbo seals moving around and oil leaking and is being forced through the plumbing.

What about pcv recirc into intake tract? Sorry I thought blow by was crankcase oil leaking into combustion chamber. What is blow by on a N/A car?
