Topic: Head Gasket/Timing chain Questions

What make, year, model was the Head Gasket Recall for?  Was it the 22re or the V-6 engine?

 When is it recommended to change the Timing Chain and Guides?

 I am looking at buying a used Yota for a DD and a little wheeling,  just kinda like to get some background info before I buy.

    Thanks in advance!

v6 3.0  bad headgaskets,   22r 60000 miles, replace with metal from various sources

best is to swap to a dual chain setup

If the 22r is good for 60,000, what is the life of the timing chain for the 22re?

      Thanks for your help above!!

Jack,  I have 340,000+ miles on my original 22r chain and guides, dual row.  Aside from changing the head the engine has never been worked on, and it still has good compression and runs well,   Nate

22R and 22RE are exactly the same.  if your engine is '82 or older you have a dual row chain and steel guides that will probably never wear out

however, in '83 toyota's bean counters had them switch to plastic chain guides that break and fall into the oilpan, which allow the chain to slap around in the timing cover and wear it away.  this can case your oil and coolant to mix(not good)

i didnt mean the 22R was used up at 60,000 i meant they usually recommend changing the timing chain at 60,000,   single row,plastic guides,     300,000, is VERY common on 20R's and 22R's
