if its NOT your compression on that, its the turbo seal

bigBOAT

what do you think is more likely.. turbo seal or compresson.. it is a zpi kit and all

tCtCtC

seal

bigBOAT

would that cause smoke out of the breather tho

tCtCtC

no

bigBOAT

so that would prolly be the pistion rings huh

tCtCtC

or head gasket

bigBOAT

dang. but wouldnt i be able to tell more if it were a dead gasket. idk.

tCtCtC

do a compression test. we'll go from there

rrimportracer

dude your soooo screwed..... take the turbo kit off... and sell it to me.... Hahahaha

bigBOAT

are those expensive. and where to look to get one done at

youngflyer

its very easy, you can fet the tester for free from an autoparts store like autozone or advanced auto

unplug the efi fuse
take one plug out and screw in the tester, crank 4 times to get compression
repeat across the 4 cylinders and if you have a drop higher than 20-30 psi on one or more cylinders, ur ____ed!

bigBOAT

ok im going to autozone today. right next to my work. i hope my compression is fine!

youngflyer

remember to pull the efi fuse out first, that keeps the car from starting!

youngflyer

actually here is also a easy way to tell if you have excessive blow-by. pull your engine dip-stick out and if white smoke is coming out of your dip-stick tube, ur motor is history!

ITS PISTON RINGS

purplenitroustc

and exactly what he said above.. I was gonna say dipstick

bigBOAT

ok ill try that when i get to work! gonna be a long drive to work just worryin about it

purplenitroustc

your block isnt gonna be re-usable if u drive the car. Your cylinder walls are gonna get scratched as hell

If it is piston rings dont worry - lifes not over - lol - i have low compression in one cylinder - about 20-30 psi below normal - and i have a decent bit of blowby and have been driving it for several months, just makes for some other issues - but ive found some temp fixes that seem to work - 1) Route pcv and crank vent with the LARGEST hose possible to a catch can - than route with 1" hosing to a slashcut on your preturbo intake pipe - this will evac crankcase as best as possible - than my trade secret lol - apparently rx7's have blowby issues even with the motor in great condition soo they add vents to the oil pan to vent the pressure right at the source - with a little clever baffling to keep as much oil as possible out of the vent hoses you can add two 3/4" vent holes to the top of the oil pan and vent up to engine bay than through a baffled catch can - be sure to have the vent hoses a constant upward angle (no traps) and have the catch can as high as possible in the engine bay - this qwill keep most the oil in the oil pan where it belongs This ventilation system will nearly eliminate all blowby unless you have serious damage such as a cracked piston, etc. But in this situation you should be seeing compression below 100psi in the cylinder and should not be driven with damage this serious - but if its just badly worn rings and the issue that caused the worn rings has been fixed (probably detonation - in my case due to some injector problems) it should work as a pretty darn good temp fix until you can build the motor - in my case when funds arrive lol
