Afternoon all,
Unfortunately I don't frequent these formus much, but when I do my answers are always answered...
Really appreciate and respect that!
So my question is, what would cause high crankcase vacuum after doing LIM gaskets and SC plenum gasket replacements?
(Opening up the oil fill-up port at idle shows high vacuum)
I checked my PCV and it looks new and rattles, although my personal service log doesn't show a date of replacement since I've owned the vehicle...
I re-checked all my upper hard vacuum lines and found a few cracked "T's" and those were repaired...
I also did a throttle body gasket, fuel injector o-rings, coolant elbows (aluminum), coolant flush (bad buildup in coolant), and checked t-stat in boiling water...
That plenum gasket was a b**** to clean off!
I am also experienceing a "knock" in the lower end (was there before lim repair)...It is weird because it is a rhythmic knock that happens every one second at idle....one onethousand...knock...one onethousand...knock...one onethousand...knock...and so on...
I've done a substantial amout of self-service to this car and to see it bite the dust will be a bad day...
Any input on what to look at next for the vacuum and a few pointers on the knock would be greatly appreciated!
