I've had the same problem for over a year but I just live with it. Have you tried RTV'ing around the ports before assembly? It seems to help mine.
I've been using Mobil 1 10W-30 as was the recommendation from the shop that built the bottom end.Chris 96 WS6 said:What oil are you using? Mine was horribly bad with Amsoil, and I went to 15w-50 Mobil 1 and its still leaking but not nearly as bad.
I'm going to be test running the car again tonight, using a breather on the passenger valve cover.Shon Herron said:Breathers might help alot, or the EVAP system connected to say the AIR pump or exhaust to get that pressure out of there....
Got a buddy that did the AIR pump thing, it worked but man, it sounded like a jet running, he took out the sound deadning stuff so it would not break off and clog up...
Are you sure you aren't just hitting the rev limiter? Do you still have the stock OPTI in it?Fastbird said:.....
Once I get some gears and tuned in it should be VERY close. I'm pretty happy for the time being, but I already see more engine work in the VERY near future. At about 6500-6700 RPM I felt the car nose over a bit, and went "Uh oh, there's my valve float." Not good when the cam is supposed to PEAK at 6500-6700 and not drop off after that.
Ummmmmm........yeah. I'm not hitting the rev limites. I KNOW what that feels like, and why in the would would I have it set of that kind of RPM when I know the cam should peak at about 6700???jpsartre12 said:Are you sure you aren't just hitting the rev limiter?

Do you still have the stock injectors in it? It could be starving for fuel if that's the case. Just another possibility to consider.Fastbird said:Ummmmmm........yeah. I'm not hitting the rev limites.

I'm also running a vented opti conversion. The nose over wasn't an ignition thing, there was no popping or anything going on. Just felt a quick drop in power. And given the extremely aggressive nature of the cam lobes, it's most likely valve float.
SVO 30# injectors, racetronix 255 LPH pump, Hypertech AFPR. Injectors have 1K miles, pump has 400 miles, AFPR has 1K miles. Fuel system is good.jpsartre12 said:Do you still have the stock injectors in it? It could be starving for fuel if that's the case. Just another possibility to consider.
