22R Timing Chain Survey -- Mileage?

You should consider changing your chain soon. You have a single-row chain (like Brush, with the '89) and plastic chain guides. When the guides break (not if; when), the chain will eat the timing cover.

I have an '82 Celica that went 171,000 with the original chain (double-row), i changed it and drove it until 211,000 and parked it for a while (needs valve guides), but bottom-end would probably go another 200,000...

I have an '83 Celica that i drive all the time now that went 209,000 with the original, single-row chain. Both guides were broken (driver's and passenger's side) and were in the oil pan. The timing cover was eaten pretty well, but not enough to cause a water leak. Noise from timing chain dragging on the timing cover masked the noise of a bent valve caused by broken chain guides. Had to remove the head and bought all new valves (for good measure). Upgraded to the double-row chain and the car is at 222,000 now with no bottom-end work.

I'll change the chain and the tensioner from now on at every 100,000 (for the double-row chain).

obviously it was a crock of ___ if the truck runs better after changing the timing chain

Can only be blamed on the single-row chain

Previous owner not changing the oil frequently enough.
