Uncleguy and any others.
I confirmed with Mother Harley back in `04 about what engine cases were suspect on the perosity issues on engine cases of the Evo's.
The years effected were from `89 through `93.
Also another issue for these cases was that there was a problem with a retaining ring coming loose. The new replacement cases eliviate both of these problems.
Now, IF......there's anyone out there that has cracked, perosity issues (oil seeping from case), etc., you can strip the cases and take them to your local Stealer for new ones. All you need, is $785 (back in `04), your original cases (left and right) and the OEM part numbers, they'll send them off to the factory for replacements. I don't recall if the shipping was included or not. So, ask them about that.
It's one of the perks that they don't advertise. As long as you give the stealer the part numbers for YOUR YEAR engine cases, the factory will stamp your original OEM VIN into new ones and ship them back to the stealer you're using.
You see, I had a problem with sending my engine through the factory reman program because I've got some goodies in it that I didn't want to loose by them being replaced with stock items. I mentioned this to a local Indy and he informed me that the factory would in deed replace my original cases with new ones and with my original VIN stamped into them.
So, look in your Parts Manual for the numbers and shell out the cash for new ones and you'll have nothing to worry about.
Although, even the newer cases aren't as well made as the early Evo's from `84 through 88. The factory, from what I'm heard, used a different casting process back then that made the earlier versions the very best of all Evo's.
Your and any `94 and up, should be fine but, let me recommend something to all of you with those year engines. Install a Carilini Torque Arm/Plate (or make your own out of steel tubing and bungs) on the right side. It connects the tranny to the right engine case. This in turn makes both assemblies rock solid and prevents flexing.........that causes cracking aft and below of the rear lifter block area.
Hope this helps clear up some misinformation that's out there.
Got problems with your Evo? Take your cases and part numbers for each (Left is a different number than the right) case along with some cash, and you'll be on the road without any worries. That is, plus the cost of the rebuild if you don't do it yourself.
Good luck to y'all.
Coaster out.............
