They all have the same valve covers as our however the passanger side one is identical on all of them BUT the driver side one you find in two versions with the breather hole either on the long side like you have on the TTA or on the short side (facing the firewall if installed on a TTA) ... either one works just depends on what works for you but if you plug the hole and use the breather in the oil fil cap/hole then either one will do the job for you.
Grab a bunch of whatever you find as these are now getting harder and harder to find out there .... you might also consider some of the hardware like the center bolt studs and rocker bolts / setups while you are at it
I broke one of the center studs on mine and had to buy an entire head to get one. I got lucky and they included the valve cover and it was the driver side so I put it on the passenger side with a breather.
It would be pretty unusual to find any of those cars in yards up here anymore. Several years ago did stumble upon a Olds Cutlass Cruiser wagon. Thing was butt ugly with wood grain side panels. Did get most of the compatible parts off of it.
If it's only the washers I would see if I could have a couple made up to the same measurements ... or try to find a similar washer (thickness and outside diameter; hole you can easily open up if too small).
I will have to see what I have sitting around that I can potentially part with to help out; not sure what I have left as I did part with a couple of complete sets years ago that I had spare.
They are on there way. I also threw in 6 nuts and some Delrin bushings for the headlight motors. I made a bunch of them awhile back at work. Feeling generous today,lol. Just glad I can help out a fellow TTA owner.
Hey gteatr6. I checked the USPS tracking number and it stated it was delayed. Didn't give a reason but we all know why,USPS sucks!!! Anyway hopefully it will show up Monday. I also PM'ed you the tracking number. Good luck with your TTA.
Hi gteatr6. Did you receive everything, any problems ?
I did come across two more sets off a 1987 t-type Lesabre and a 1988 Olds. Also grabbed the center bolt studs, passenger side valve covers,egr cover and plug wire boot protectors. Does anyone know what else is compatible with our TTA's? These cars are at a pull and pay so parts are really cheap. I do plan on going back soon to get the power seat track out of the Lesabre for my T-Type so if anyone knows of any other parts that are the same for the TTA please let me know.
Hi TeeTopZ. The covers i picked up were both passenger side covers. The drivers side cover on both cars are different than the TTA cover(see Jan's post earlier). If I come across a correct drivers cover I will let you know.
Thanks. I would be fine with the cover that has the hole on the short side as Jan noted. I will just plug it anyway. I just want the ability to add a breather to the passenger side. So if you happen to go back to the yard and that is the cover they have, I will gladly take it. Thanks.
I think I might go there tomorrow to get a power seat track so I will pick it up for you,no problem. If I remember correctly they charged me about $12 for a valve cover. I love those Pull and Pay places,the parts are dirt cheap. Seems like I always end up buying more stuff than I plan on. I hate to see good parts go to waste.
