I'm a proud owner of a 88 Camry All-Trac. Gold in color, 3s-fe, 245,000 miles, 75,000 on remanufactured engine, 5 speed with some weird maroonish brownish interior. Picked it up from my cousin for $600.00, not sure if it was a steal, a ripoff, or just a decent deal.
Anyways, i have a few questions.
1. On cold startup, there is a little engine chatter for maybe a second till the oil pressure raises then it's gone. My father said that possible the rod or main bearings were a little loose and until the oil pressure raises they slap around a little. He said as long as I don't abuse the car that shouldn't give me any trouble for a while. Anyone else have similar problems?
2. I want to replace the struts and was wondering if it is difficult to find the rear struts. Some of the local auto parts store didn't have them but I haven't checked a Toyota dealership yet. I've read that they are the same struts used on the first generation Celica All-Trac, can anyone verify this?
3. Finally, a long one. This has to do with tire sizes and i'm kinda pissed at myself for this one. Earlier today I was working on my Celica fixing the front breaks when I had the brilliant idea of seeing how my celica wheels would look on the camry, I figured what the hell I already have two of them off... They looked nice so after finishing up I was driving to my girlfriends when it dawned on me, crap, two of the tires are 225/50/15's and the other two are 205/50/15's.

Originally bought the 225's for the rear of my celica to widen the stance just a little and of course they rubbed on the struts so i had to put them up front. On the celica this didn't really hurt anything but on the all-trac, well you know the dilemma. It was about ten miles to the gf's and I took it slow on the way back, did around 40 to 45 the whole way, whether that helped my situation I don't know. I did the calculations at
http://www.miata.net/garage/tirecalc.html and the 225's are 8/10ths of a inch taller therefor turn about 30 times less per mile. Now for the questions.
3a. Do you think any harm could have been done from a 20 mile trip. I have a feeling it could.
3b. With 245,000 miles on the drivetrain do you think it's already pretty worn out?

3c. How would one know if any harm was done?
Thanks for taking the time to read and any answers would be greatly appreciated. And if your gonna mouth me for making this mistake, please take your comments elsewhere cause no one really cares to hear them.
