Dec 16, 2006 Has anyone seen an aluminum valve cover for the 2.5L? Or any other aftermarket valve cover? I really don't have any problem with the original, but would like an aluminum for the cooling and cool factor. I also have heard that there are some sealing problems and I am going to replace my noisy lifters. Might as well change the cover at the same time. Any

I am guessing you have a older TB injected 2.5? Because every 2.5 91-95 have had aluminum valve covers stock. Mabey you can get one from a later model. But I have no clue if they will fit or not. Dont know if you know this or not, but to get to the lifters you have to pull the head, not just the valve cover. Joined Mar 21, 2006 · 2,931 Posts
yo if ur that worried about a aluminum valve cover for cooling y dont u keep ur stock valve cover and get a oil cooler they are about the same price and that cooling effect will be far greater than a valve cover..

Sorry dude, but "2.5L" and "cool factor" shouldn't be used in the same sentence. From one 2.5L to another..:laugh: Joined Oct 26, 2005 · 513 Posts
The 88-91 YJs used a plastic valve cover, where the 92-95/96 used an aluminium valve cover. BTW, what kind of lifters are you replacing the stock ones with? Joined Oct 5, 2004 · 106 Posts
Discussion Starter · #7 · Dec 17, 2006 My mistake I feel kind of stupid, I didn't even check my valve cover. I just heard that the 2.5L has a tendency to leak when gasket is replaced and they said it was because of ut being plastic. I did not know that my 95 had aluminuim, I never checked. I don't know what lifters I am going to use, probably just OEM. Any ideas on

Does anyone know if they make aluminum valve covers for a 2.5?

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 :)

I look thanks, mine just cracked and the whole 2.5 is starting to tick me off.

Will a yj 2.5 valve cover swap right on to an older 2.5?

Yes. An AMC 2.5 is the same as a Jeep 2.5. The YJ cover will work.

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.

What year dakota did you get the gasket from? I have an aluminium vc no gasket... the vc is from 94 yj and the only gaskets I can find are cork...

Do you remember what size bolts for the aluminum cover are? I'm switching from plastic and new cover did not come with bolts...
Link to commentShare on other sites
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.

Thanks for the replies. Yes I was wondering length and threads for the bolts.

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

I know this is an old thread but do not buy the 98 dakota felpro rubber gasket. It is not right I just tried. I have 2 2.5s now and have found jy aluminum covers to replace the plastic and I'm having trouble locating the correct non cork gasket myself. I just ordered a crown one for a 93 cherokee 2.5 aluminum cover from rock auto and hopefully it is as advertised for this will be the 3rd 1 I ordered as rubber and showed up cork with the advertised part number in description from rock auto. Some say cork for aluminum, but I did not order those so I will update with results for this is the 4th 1 I will have tried total.

Grind the lugs down on the back of the cover as shown, use Felpro blue rubber. Nothing else works.

Which felpro part number? I have now just ordered my 3rd gasket. I tried part # vs 50502 r which is felpro for a 98 dakota 2.5 and looks nothing like ours 6 bolt pattern and straight down both of the long sides. It was sealed in the box from factory. I also tried vs 50541 c which would work but its cork with a very weak rubber coating. I want the one in pics ive seen. I have used it on all my i6s in past and never a leak with any not once. Some I had near 100,000 miles on. It was worth the 30 or 40 bucks hands down.

And love that motor. I already took the paint off and started sanding to polish. I had to soak the crusty jy cover for a weak to clean the 20 + years of neglect. The oil was so burnt on there it was flaking inside in some spots and it had a handful of sand it seamed caked in it.

So autozone has got a 3rd felpro vs50502r on its way. 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.

In their defense, its not autozone. The actual part in the box has a different part number than what is stamped. It is not just autozone too. I went to autozone after this happened in an online order which I thought was my error. What is very apparent is the factory has either mislabled the box or placed a different part in the labeled box from the manufacturer which is victor reinz. I should have looked at the production dates or line number, but I returned the first two before we figured out the parts had a different number than the box. So this was not just 1 autozone nor only autozone.

Rock auto gave me the same thing by the way. I image I am gonna have the same luck no matter where I get it if its a felpro of same run. If it happens again tomorrow, I will post all packaging info from the label so others can verify. The cork gasket that came from rock auto was accurate though but its cork. This was suppose to b a spare that I got for less than 2 bucks. I may end up saying the heck with it after tomorrow. If its the same thing I will have wasted more time and gas tracking it down than its worth.
