Well here goes i have a 96 integra gsr. Motor is a type r the bottom end i got from acura brand new last year and the head is a 97 jdm type-r head. when i got the car the setup i had was gsr bottom end with the type-r head i had blow by then when i would drive it hard so i figured it was the rings so i had the bottom end bored out a bit put in some ctr pistons had the head checked and valve seals replaced and still blow by when i drive it hard. So a year or so goes by and i spin a bearing so i order the type-r bottom end completly assembled from acura had my type-r head hot tanked valve guides checked and valve seals replaced again and what do ya know still blow by when i drive it hard. So at this point the only thing i havent replaced that could be causing the prob i believe are the valve guides. Any other opinions on what could be causing this any input would be greatly appreciated.

 

Any ideas

 

check your pcv system, sounds like a clog. valve seals and guides will normally leak under high vacuum, not wot. i assume that you have blue smoke when under wot which would indicate blowby. also it sounds like your comfortable with taking your engine apart, so maybe take the head off and look at the cylinders and the pistons for signs of blowby. i dont beleive that you have a problem with blowby only because this is your 3rd bottom end and still having the same problem, i would say it is somthing else causing it to burn oil

 

Yea I've replaced the pcv setup and put in a catch can I pinched the line the pcv dropped and there a no leaks in the line so I'm just at a loss. Spark plugs are dry not saturated in oil. Thx for the reply
