54bobby Posted January 28, 2014 Posted January 28, 2014 what the hell would crack the valve cove? about a 2" hair line crack one the side near the top by the rear vacuum line fitting. grrr. oil leaking right through.
Jeep Driver Posted January 28, 2014 Posted January 28, 2014 25 year old plastic. What would you expect?
88whitemanche Posted January 28, 2014 Posted January 28, 2014 Could have been the valve cover bolts being too tight and slowly cracking but replace it with a newer aluminum valve cover best upgrade yet and make sure you get the 98 Dakota felpro gasket...no oil leaks in months since replacing it
54bobby Posted January 28, 2014 Author Posted January 28, 2014 where can I get the aluminum upgrade cover and will it be compatable to the 87 model year?
88whitemanche Posted January 28, 2014 Posted January 28, 2014 The 2.5 valve covers were plastic... And you can get those valve covers from any cherokee if I'm not mistaken from 93+
54bobby Posted January 28, 2014 Author Posted January 28, 2014 but which years used the aluminum covers? and will they be compatable with the 87 model year? need to get one asap.
88whitemanche Posted January 28, 2014 Posted January 28, 2014 Yes they will be comparable I have one in my 88.... Years 93-01 iirc...but they don't sale these online new...you would have to grab one from a junkyard...
54bobby Posted January 28, 2014 Author Posted January 28, 2014 anybody got an extra they wana get up off of?
88whitemanche Posted January 28, 2014 Posted January 28, 2014 I had an extra one but helped a buddy out...I'm going to a junkyard tomorrow I'll see if I can pick one up for you....
54bobby Posted January 28, 2014 Author Posted January 28, 2014 I found a couple on fleabay but they are pricy. 75 and up? wtf? also, the ones I found do NOT have the opening for the vacuum return at the rear of the cover, only the fill cap and the line that runs to the intake. would it be compatible and what would I do with my existing vacuum line? just plug it up and if so, would it affect performance?
TheDirtyJeep401 Posted January 29, 2014 Posted January 29, 2014 The aluminum valve should be a direct swap. The only thing you have to change is the front hose for the PCV. Since there is a brass fitting.
54bobby Posted February 8, 2014 Author Posted February 8, 2014 well I replaced the cracked valve cover with a new plastic one. i'll keep my eyes open for a clean metal one. the fleabay ones where beat to hell. I also gave her a tune up w/ plugs, wires, cap and rotor. no need to move the ac unit to change the #1 plug when the vc was off, fairly easy acess. hardest part of the job was getting that rear bolt back in in the dark at 25 degrees.
