Engine was pulled from my car today and they found oil residue in the downpipe... they're is no play in the turbine shaft and the turbo has less than 1000 miles on it. Haven't taken the head off the engine yet, but the mechanic says that my turbo may need rebuilding too.

question:

can oil in the exhaust side be cause by bad piston rings or is it more likely to be blown turbo seals?

 

Could be both.

what would cause the seal to blow after 1000 miles? Id on't want to repeat the same mistake if it has to do with my handling of the turbo

 

I doubt its blown.

 

you think its just my piston rings then? either or is fine but both is gonna hurt!

 

what happend to your piston rings? You didnt have your fmax kit that long, did you?

11:1 compression
boost spike to 1 BAR
running really rich
pos untuned MF2 on for 3 months

take your pick...but I was gonna get low comp. pistons anyways...just came sooner and more unexpectedly than I wanted

i'm in the same situation as you MiriaZ

although there is a lot of air pressure coming out of my valve cover breather, and sometimes white smoke comes out. i'm very upset.. spent so much money already.. guess now I have no choice but to move to step2 of my project.. buy JE 84mms, swap in B18C crankshaft and use my existing B18C eagle rods into my B20B block, and set new C/R. *sigh*

 

well...hopefully I get it right this time...this garage is suppose to be damn good...

 

good luck

 

any other experiences with oil on the exhaust side?

 

white smoke might not be oil!! also just do a compression check to rule out the turbo as the cause.

 

if you have to big of oil feed line to turbo(i.e. -4) then you need to go down to size -3

 

Glad you finally found someone that could help you Bob.. ...my *** was just to damn busy if you know what I mean ... But I bet you a good chunk of $ that they take the block down to the same shop where I was going to have yours honed at Mitomi Bro's in Yokohama.. 90% of the speed shops in that area use them....

Talk with ya in about 4~6months when I get off the boat
