Like the title says. I installed the dual pass and s3 h/e and started the car up and it ran fine for a few minutes. Then it bogged out and wouldn't start up anymore. I had a friend come over with a tuner and we still couldn't figure out what was going on. After about an hour or so, the car finally started up and was blowing white smoke. Smelled just like coolant so I pulled the spark plugs and sure enough, they were soaked in coolant. My question now is what could be the problem? What is it that I may have screwed up? I switched the laminovas around just like the write up on here says. The only issue that I can think of is that when I removed 2 of them, I bent the end that sticks out into the dual pass ever so slightly and that could be where its leaking from. If anyone has any insight on this issue, please don't hesitate to let me know. I really need 2 get my car back up n running cuz its my daily driver.

 

seals on end of cores

 

The o-rings or the thin metal seals?

 

.
memory description.
happened to me a couple months ago. I believe there are rubber o rings on the core ends that come out last in the stock config. 4 brass washers on the end of the cores when u take the stock end plate off. my brass washers were stuck in the stock one and I never saw them cause I had a nice and clean dual pass from italianjoe ready to go on.


Pull it back apart and u will see what was wrong. I have only had it apart those 2 times so I can really give an accurate.

 

as he said, you will see it soon as you pull it apart, something didnt go back together right and coolant is leaking from the cores into your intake most likely

 

Just making sure you didn't put coolant in the boost bypass hole on the endplate?
