I have seen references to the timing chain tensioner guide on this NG.
What is mine made out of?
Is a metal guide an aftermarket product?
Do I need one?
The motor has over 150K on it.
thanks

The factory guides are plastic. Timing chain should be replaced at
around 100K, maybe sooner. If you don’t know how long yours has been
on, I’d suggest changing out everything. DOA Racing makes a nice metal
backed chain guide and also has complete timing sets, etc.:

I have a ’82 with a 22R. Drove it hard for many years. I finally spun a
bearing at 250,000. I never had a problem with the timing chain. Just
reference for you.

If your engine is the factory engine, you should have a double row timing
chain and metal chain guides. I believe they changed to plastic guides
around the manufacture date of July or August 1982. My 83 Toy 4×4 was
manufactured in September 82 and I just checked on this last week with the
Toyota dealer using my VIN & manufacture date. I went in person and looked
on the microfiche myself. To verify that, look on the driver’s side door
panel and get the date of manufacture from the truck. You can call any
Toyota dealer who can look on the microfiche for your VIN# and production
date. But, like I said, I do believe you have the double row timing chain
and better chain guides.
Of course, the definite way to check is to remove the valve cover and look
down there for yourself. This would definitely confirm it. I too have
around 142k miles on my original timing chain/guides and will get around to
changing probably to the double row sold by DOA Racing.
Good luck!

Yes I have double row.
Thanks

Ive got an 89′ 22R with 176,000 miles on it. Had the timing chain, gears
and tensioner replaced at 140,000 miles. The tensioner was made out of
phenolic. From what I understand is that the whole assembly tends to wear
out at about 140,000. If the phenolic tensioner breaks you will hear a
rattle at the front of the engine when quickly accelerating the motor (chain
rubbing on case). My mechanic told me that the reason the tensioner broke
was because I wasn’t using Toyota oil filters allowing the oil pressure to
bleed down and allowing the tensioner to retract. Upon cold engine start
and no oil pressure forcing the tensioner to the chain, the chain smacks the
tensioner until full oil presure is restored.
