Chinese Knockoff 22re Block Line Bored Wrong
I am new here and just went through a hell of time fixing a toyota pickup--it took a year to figure it out (ok, well 9 months of weekends but who's counting). For those that don't want to read the whole thread, let me summarize.
After doing some research and finding no substantive issues (documented that is) I bought a new chinese knockoff 22re engine and put it into a 86 4x4 Pickup (EFI, auto trans, etc.). The truck ran great! But it started breaking flex plates. After 4 flex plates and $2000 total cost, I figured out that the crankshaft was 2mm too high in the block. Not enough to affect the engine operation but really flexed and broke the flexplates. I documented this what happened so if folks are interested let me know.
What is interesting here is that as the vendor said, this can't be because they manufacture these in runs of 500 and he has sold 1000s. My thought is, either there are thousands of mis-manufactured 22re blocks out there or, I just happened to be the unlucky "1"--and I doubt that.
Doubt it or not, I posit that if one of these engines are placed in a car with a manual transmission that the effect will not be seen for "perhaps" years. It is only in an automatic you'd see the effect in short order. Think about it, we had 4 flexplates fail in less than 2500 miles.
Finally, if you have one of these engines and you have a small (or large) mainseal oil leak, this is one of the symptoms. In my document I show that mail oil seal is overly compress at the top and not touching at the bottom.
I am really curious to find out if I am the only one.
Thanks for reading, Ted
