If the lower intake was not sealing good could the car run good.. The reason I ask is I removed my intake to check the baffle on my elderbrock intake.. I am having smoking issues got the tapping noise took care of for the most part.. I checked all plugs and two were black.. I am thinking that the intake gasket is not sealing good and it is sucking oil through into the heads if that is possible..

which spark plugs? the back 2? what kind of intake do you have? some intakes have trouble sucking oil up through the pcv. that may be what you are experiencing.

I have a performer intake and it is # 2 and # 3 the rest are a greyish to tan color.. but all ports on the heads apear to have signs of oil in the intake track..

the performer is one of the ones that people have had troubles with.

check this thread: http://www.corral.net/forums/showthread.php?t=912459 this one is about the rpmII intake but there have been problems with all of them.

this thread for example: http://www.corral.net/forums/showthread.php?t=803103


take the side plate off and check it out. if you are getting oil inside there are a few things you can do that may help. first is to replace the pcv screen and valve and make sure you have all pcv components in place(valve, screen, grommet, TB-to-Oil Filler Tube hose).. you can also use a larger diameter hose to cut down on the velocity of crankcase fumes which will help keep the oil out. you could use a second PCV valve like vristang shows on his website: http://www.freewebs.com/vristang/pcvoil ... issues.htm . also you could take the intake off again and fab up a baffle like shown in the first thread i linked you to.

or you could eliminate the PCV entirely. disconnect and plug the pcv valve, disconnect the TB-to-Oil Filler hose (and plug the ports) and put an open breather in BOTH of the valve covers.

hope this helps
