Default Those with Super Ram please help.

How do I get my valve covers back on with the super ram installed? The driver's side is easy but the passenger side is rediculous!

You have to take off the AC compressor.

It's easy, just take off the inner fender well, 6 or 7 screws, and four bolts and the compressor is off.

I have the long compressor, I expect you do too.

They are all 10MM bolts. You need a 1/4 inch ratchet and a 10 inch extension.

The bottom right bolt has a 13MM nut at the end.

I took a grinding wheel to the cover (top side toward the runners) and took off about 1/16". Next to get them on to the passanger side, I slip the rear on as far back as it will go, lift and pull the heater hose (TB by pass) over the lip of the cover. Didn't have to touch the air conditioning. I have only done this about 4 times in the last two weeks....lots of practice!

I have taller VCs. That's probably why I need to remove the AC.

Yes, you can wiggle it around pretty easily

I'm pretty sure he's got the A/C moved at this point due to having taken the v/c's off. even my stock passenger side v/c wasn't going to come off before the a/c was moved.

At any rate I took the dremel to my valve covers and put two 3'to 4' notches in them to clear the runners.

I had the Superram in the past and the best thing you should do would be to shave the valve cover in order to clear that pain in the *** runner. Be careful with the magnesium shavings as they are very dangerous if you know what I mean.

I didn't have to shave the covers at all.

I am using stock 85 covers, drip tabs have been cut off. I just went to the 74211 cam which has a exhaust lift of .562" with 1.6 RR's. On the exhaust RR's I sanded off the back corner of the RR at a 45* to get the RR to clear the covers. It (exhaust RR) was just kissing the valve cover. I also use a extra thick gasket.

The drivers side cover I have to remove the air pump to get the cover on and off. PITA .

Thanks for the help everyone. The drivers side is not much of a problem but the passenger side is a PITA. I managed to get it off pretty easy with the compressor on believe it or not. I'll just take the compressor loose this time to get it on.

I won't need to disconnect the lines to it will I? My air is blowing nice and cold and I don't want to ruin that!

Anyone have pics of the shaving they had to do to their parts?

No you won't have to disconnect the lines just ease it up after you unbolt.

You can trim the stock valve covers to fit. I got a set of Proform tall valve covers. They cleared the Superam runners and my 1.6 RRs with no problems. I think it looks pretty good too.

Instead of trimming the valve covers, I ground some "flats" on the SR runners with a belt sander at the point where the valve covers tend to interfere.

My runners were used so it was pretty clear where the interference was occuring due to the existing scratches and gouge marks on the runners from a previous installation. That's where I put the flats.

On the passenger side, I also move the A/C compressor out of the way.

It does become a bit of a nuisance for running the engine without the valve covers on, since you have to put the compressor back in place and then pull it again to reinstall the covers.

For those that can do it with the long A/C compressor in place, I'm impressed.
