    Evaporator plastic cover

    Thanks Barney, The part is the outer one. It's called the Cover Blower Case # 52455957. I've found a few but they were in bad shape. I'm thinking I will end up using some stick-on heat shielding as the plastic cover's only function seems to be insulating the evaporator from heat and noise. I found a 1990 Reatta at the local salvage yard but forgot to get the VIN for the database. Will go back soon.

    Evaporator plastic cover

    I decided to replace my evaporator today and discovered the plastic cover is not reusable. It cracked and came off in pieces. It was very soft in some places and just crumbled in others. I think the oil from the leaking evaporator may have helped to break it down. It's had a slow leak forever and I was getting away with just adding R134 to it when needed. Does anyone know of a source that is replicating these covers? If not I'll try to find a good used one. Thanks

    Anyone Ever Seen one of These? Driver Door Tag

    It looks like a re-work ticket. I'm guessing there was a repair loop for door panels.

    Non-ethanol gas...noticeable improvement!

    After I posted I started wondering as I too haven't seen any ethanol labels recently. I guess they passed a law awhile ago to only require an ethanol label when it's over 10%.

    When did Michigan go ethanol free? Last night??

    89 Reatta runs fine cold, runs rough when warms up

    Based on these numbers it appears it is not going into closed loop. Is the integrator changing value or is it stuck on 128?

    "Body in white" was a term used to describe the body as it came out of the elpo dip prior to being painted. The term may have been used differently from plant to plant but that was the definition we used at the Fisher body plants. Some defined body in white as prior to the elpo dip but in any case it was the steel body prior to any assembly operations in the "trim" shop.

    Need Help with Rough Idle on a '90

    Pull the EGR valve off and check for carbon. A piece of carbon holding one of the pintle valves open will cause these symptoms. The integrator is trying to compensate.

    Oil Pan gasket- dry install with no RTV?

    You need to put a dab of RTV at each "T" joint. Just like it shows in the instructions. "T" joints are the interfaces, or junctions of the three surfaces; as in oil pan, block and front cover. Production tolerances usually result in a mismatch where the pan rail of the block meets the front cover and rear seal carrier. They are called "T" joints because the sealing surfaces of the three parts form a T. The four spots in the picture calling out RTV are the "T" joints. The rest of the surface should be dry.

    Serious Engine Issue - '90 Coupe

    Sorry to hear about the cam failure. I've only seen this one other time on a 3800. The likely root cause is a seized cam bearing from lack of lubrication. Once the bearing seizes, the cam gets twisted and fails. Hope someone here buys it and puts an engine in it. Repairing the old one would require line boring the cam bore to prevent a repeat.

    Serious Engine Issue - '90 Coupe

    None of the valves would be moving if you lost the timing chain. You mentioned some are moving. My guess is you broke a cam so the front cylinders still have function but the cylinders rearward of the point of the break in the cam are not. Never seen this happen but that's one explanation. Another could be bent push rods.

    Reatta option look up

    Does anyone know what RPO code R7M is? It is a sales item code but what is that and what actual content comes with it? I used Compnine (non subscriber) to search rarity and discovered this code makes a big difference in rarity. I did a search but no luck.

    Fuel Pump - Next on the List...

    If you take out bolt "3" on both sides the stabilizer bar will swing down enough to allow the tank to come out.

    CD player bad - any suggestions for repair?

    Yes, you will have to remove it and take the top cover off to clean the optic. I wouldn't try sticking a Q tip thru the slot. I didn't have much luck with the CD cleaning disks but I've never used the type that Corvanti described that uses cleaner applied to it. The one I tried simply had a small brush that is supposed to knock the dust off the optic. It didn't work for me.

    CD player bad - any suggestions for repair?

    Mine was doing the same. I took the cover off and cleaned the laser optic and it works fine now. Try some isopropyl alcohol on a Q tip. I left the cover off, plugged it in and tested it and it worked better so cleaned it again. Be gentle with it and let it dry before trying playing it. The Q tip should just be damp not soaked with the alcohol. Use 90% pure. Should be able to find it at any drug store or even the grocery store. Good luck.
