smoke screen

[sidewaysFC]

my cousin has a white 87 rx7 that he calls smoke screen and ill tell you why. if he holds the engine at or above 4000rpm or if he runs it very hard it starts to pump a huge amount of white smoke out of the exhaust like he can white out a whole road and blind every body on it but it runs like a top. he bought it last year and it was supposidly rebuilt with few to zero miles on it. it didnt run when he bought it it had a big vacum leak we had to fix ,and also it burns a lot of oil and the oil pressure is maxed out on the gage . I was thinking this could all be from an improper brake in or some clearenses in the engine could be to tight cosing to much oil pressure.

Well the white smoke would suggest to me flooding or again coolant seal failure issue.

that makes sense ill have to ask him if has losing any coolent and ill have to try that way of testing for a blown coolent seal you said
