TheDirtyJeep401 Posted June 7, 2013 Posted June 7, 2013 Does anyone know if they make aluminum valve covers for a 2.5?
87Warrior Posted June 7, 2013 Posted June 7, 2013 Yes. The non renix 2.5L motors generally had an aluminum valve cover. When you find one, buy a Fel-Pro Permadry gasket for a '98 Dakota 2.5. No more cork leaks. That said, I suspect the valve cover from a 2.5 Dakota should be aluminium and should work on the Jeep, but I do not know for sure. My '86 2.5L sports an aluminum valve cover from a '93 XJ and the Permadry gasket for a Dakota. No leaks :)
TheDirtyJeep401 Posted June 7, 2013 Author Posted June 7, 2013 I look thanks, mine just cracked and the whole 2.5 is starting to tick me off.
TheDirtyJeep401 Posted June 12, 2013 Author Posted June 12, 2013 Will a yj 2.5 valve cover swap right on to an older 2.5?
87Warrior Posted June 12, 2013 Posted June 12, 2013 Yes. An AMC 2.5 is the same as a Jeep 2.5. The YJ cover will work.
onlyinajeep726 Posted June 12, 2013 Posted June 12, 2013 All the AMC/Jeep 2.5L valve covers will fit one another regardless of the year. The Dakota used the AMC 2.5L (not to be confused with the 2.5L Chrysler K-series engine that was used also). But, keep in mind that if you're going from the plastic VC to the aluminum one, you need to use the longer bolts that are found with the aluminum VC otherwise you won't be able to bolt it down. I found that out that hard way, but luckily I held on to them from the junkyard.
TheDirtyJeep401 Posted June 12, 2013 Author Posted June 12, 2013 Ok, saw something about it and wasnt for sure. Thanks
cz777 Posted June 20, 2013 Posted June 20, 2013 I look thanks, mine just cracked and the whole 2.5 is starting to tick me off. YUP ...i heard that pain well ..i found a 94 xj aluminum one 3 years ago in the bone yard for 20 bucks ! yes they are out there ,seek and you will find one ! its worth it !!
TheDirtyJeep401 Posted June 21, 2013 Author Posted June 21, 2013 I want to find one. I bought a OEM replacement and now my rockers are hitting the valve cover. :wall:

I have an aluminium vc no gasket... the vc is from 94 yj and the only gaskets I can find are cork...

I'm switching from plastic and new cover did not come with bolts...
88whitemanche Posted July 3, 2013 Posted July 3, 2013 98 Dakota gasket and iirc the bolts are either a 10mm or 11mm
onlyinajeep726 Posted July 3, 2013 Posted July 3, 2013 Bolts, no idea... Gasket, here you go: Rubber valve cover gasket Jeep 2.5L
onlyinajeep726 Posted July 3, 2013 Posted July 3, 2013 98 Dakota gasket and iirc the bolts are either a 10mm or 11mm I think he was referring more to the length, as that is going to matter more since the aluminum base is thicker than the plastic.
MJ1337 Posted July 3, 2013 Posted July 3, 2013 Thanks for the replies. Yes I was wondering length and threads for the bolts.
ComancheBill Posted June 23, 2015 Posted June 23, 2015 Hi all just thought i would throw some things out there. I have a 86 V6 and a 87, 2.5, 4 cylinder and i have replaced both engines with re-manufactured from Gearhead's Engines, when the 2.5 was replace I got a cover from Auto Zone for $60.00, it is a special order but it is aluminum and works well with a good gasket ( Not Cork). Also there is a company in England that has redesigned performance carbs that has been work awesome for power and mileage in my naturally aspirated V6. I will try to hunt down the name, its been a while since I ordered it. Just some info. Cheers
Jeep Driver Posted March 5, 2018 Posted March 5, 2018 Grind the lugs down on the back of the cover as shown, use Felpro blue rubber. Nothing else works.

It now appears after checking and rechecking pics and crossreferencing to no end that there may be a production packaging error. If the 3rd one comes back the same I will order the mahl version which is more yet and takes longer to get. The last one we tried was opened and returned already. This is your problem.
