sounds like back pressure.. but what are the benefits of blanking off the EGR valve?

the EGR tends to introduce alot of soot into the intake manifold over time as it recirculates exhaust gases, blanking it off reduces this problem.

to the op, does your engine have a PCV valve? it may be stuck closed causing your problem as well as blowing out of front and rear oil seals etc, the gauze in your tappet pan cover mite also need a good clean too if the crankcase is venting thru your dipstick
