When I replaced the LIM gasket yesterday, it took me 18hrs! (well 4hrs break, 4 hours due to meticulous cleaning, and doing it in the driveway where it's 25 deg and windy, first time LIM for me.) I took alot of pictures, but I thought I would share some of what I found...
First, the injectors were filthy!
Next, even though this pic is a little blurry, you can see where this gasket is full of FAIL! (even missing chunks...geez)
and now after replacing w/ a new aluminum one
ok, heres an injector hole and valve cover in back(thats a "white" valve cover)
and after cleaning/reinstall new gaskets, the same injector hole...
From now on I'm definitely going to keep my engine clean and degreased! Oil+dirt+sand=YUK!
I am wondering though, I haven't had my engine cover on for over a year, would having it off increase the amount of dirt that gets in all over the place?
My advice is if you're going to do this yourself, make sure you have an extra vacuum line + Ts, they're gonna break. Degrease and clean the darn thing BEFORE you start.
