When my 22re warms up it sounds like the timing chain is scraping against the timing cover. I have replaced the chain, guides, and tensioner twice in the last year. Both kits came from my local Advance Auto Parts store. It seems like the tensioner just isnt doing its job once the engine warms up. Should i have just ordered the tensioner and chain from Toyota? Could it just be that the tensioners and chains from Advance just are cheap junk? I feel like i shouldve just ordered them from Toyota. Is there a big difference in factory toyota tensioners and aftermarket ones? Thanks for the help!!
