make shure you get the rubber ones, the cork ones suck. and be prepared to get mad it took me forever to do the driverside valvecover

I did mine yesterday...NOTE...when removing the valve covers make sure no HARD pieces of old gasket break-off and fall somewhere they shouldn't! Pull the old gasket set-tabs off before pulling the cover...don't want one to get inside the head >the oil drain holes in the back of the head are quiet small.
My original rubbers were rock hard and easily cracked.
Fel-pro offers a replacement 'rubber gasket kit" # VS50247R 1988-1994....$8 bucks at Advanced Auto.
The drivers side wasn't too bad, the passanger side can be a PITA I had to remove my fuel filter etc to lift it off. Also the rear bolts are a pain...had to lay over the engine to get them out/in.:thdown:
While visiting the inside, suggestion...grab each rocker/valve to see if the springs/valve/guide's are all tight. Idle engine to observe oil pumping out all push rods...also...while ideling observe all rockers are lifting the same height.
When installing, use something like Hi-Tach on the cover side gasket to secure it to the cover when installing, I would leave the bottom/engine side of the rubber dry >don't need it slipping out.
Nice a clean inside...

I did both of mine last month and I didn't have any problems taking them off. I agree get the felpro ones that are rubber. also you might want to look at the hold down tabs to be sure they still have a little bend in them. they will get flat over time and then they won't exert the proper amount of pressure to hold the valve cover tight. I even powdercoated the covers while I had them off

Yea it looks as the passenger side will be a pain and yea looks like the fuel filter and alternater has to come off, am i right? Yea im 100% getting a rubber one, thanks guys ill be doing it in two weeks.

Yep- you have to take all that BS off the front. Nice, huh?
Good luck on getting them to seal up- I did the valve cover gaskets in my '94 with the motor in and they leaked a little bit from the first mile. Let's hope I got it right on the '89.
I wouldn't put any gasket sealant on them- usually putting things on rubber gaskets is advised against. The tabs on the gasket will hold them in while you drop them on. The problem I had is the gaskets never seem to be fit the cover very well.

HamerDown- I can say that the underside of your valve covers is MUCH cleaner than my '89...

It is not necessary to remove the fuel filter or alternator. The cap screws are not very tight. Use a 1/4 inch socket set with a 5 inch "wobble" extension on the screw under the filter. I was able to get by with just a straight extension by slightly moving the extension off center and putting the socket on the screw head at an angle. I had to get my wife with smaller more nimble fingers to get it started when replacing the screw. Use 12 inch/lbs. torque on all the screws.

94 IDI with factory Turbo

Hi Guys,
I need to replace my vc gaskets and need to know if I have to remove the turbo or parts of it in order to do this. Does anyone have pictures or manual pages to help out? When I replaced the gps I did have to remove the front part of the turbo in order to get the back ones on the drivers side. Also, I read that I may not have to remove the fuel filter or alternator, but with a turbo is that the same?
Thanks for all your help, you guys rock:thumbsup:

When I did my V/C's I didn't have to do anything to the turbo. I don't even remember removing anything but the V/C bolts and moving the GP controller out of the way.

Thanks, I will give it a try. Can't be too much worse that changing the gps...
