i blew out my dipstick ??? i have a 2002 gmc sierra 5.3l in it i have a ATI Procharger runnin 8-9 psi .
i've had my oil dipstick blow open and squirt oil all over my engine under full throttle .
truck has 3500 miles on it 1000 of them with the procharger on it everything else is stock except for a BBK throttle body . The only thing different since i've had it installed are some new ngk tr6 plugs and msd wires.I also found that the dude who did the install missed a gear clamp on the throttle body thus was leaking air at full boost ...made a difference to feel all the boost ..
Any ideas on what i might have blown up ...
the truck idles and runs just fine no loss in power no engine lights either ??

Re: i blew out my dipstick ??? I'm just guessing--but your crankcase is being over-pressurized because of the s/c. This(over-pressurization) happens to some Lightnings although I've never heard of our dipsticks blowing out. You might want to look into getting an oil breather cap to replace the stock filler cap. This may cause detonation because of allowing unmetered air into the system but we adjust for this with our chip.

Re: i blew out my dipstick ??? Powerdyner's had this problem. Happens especially if you leave the pipe from the throttle body to the passenger valve cover on. You may also want to add a check valve to the PCV pipe which runs to the Throttle body.
