Hey guys just need an opinion. I have a 99gsx that I did a 6 bolt swap which also is a 2.3. Bottom end is brand new manley pistons with 1g rods. Head is a 2g head with hks272 cams and dual valve springs. Running an hx40 t3 housing. I broke the engine in via the motoman method. After first 20 miles I changed the oil. Soon after I noticed that the engine smokes under decel only! After there is any load put on the engine it will smoke on deceleration. I then tried putting my stock vc back on with the factory pcv system in place thinking that could be the issue. Didn't really help much so at 60 miles I did a compression check and it was 115 across. Figured I would keep putting miles on it hoping for the smoke and compression to go up. I have been driving it fairly hard on 8psi then decelerating hard. I am at 200 miles now and changed the oil again. Smoking hasn't really let up and I did another test and its only 120 across. Remembering now on first start up the injectors weren't setup quit right and for the first 2 minutes was idling very rich. I am afraid that may have done me in getting a perfect break in. Should I keep driving it till 500 and retest or just pull the bi*** down and re ring it again. I am super bummed this is happening but I wanna get it addressed before our local track opens. I spent all last summer doing the full build and really wanna race this year. Really appreciate everybodys opinion and help.
