Timing chain noise...with new timing chain?

[mooseketer]

Did you ever find out what was making the timing chain noise? I am about to replace mine with a kit from http://www.partsdinosaur.com/ and only want to do it once. Any advice would be good.

The best that I can figure is that I somehow got a bad timing chain tensioner, or my oil pressure is a bit low. I dunno...

Fellas, i will update you guys on my findings. No power caused by tps not closing and running 20 degrees late. Bad news, got timing right on and heard knock in lowe end. Put a 85 motor home 22re engine in with 36,000 miles on it and runs perfect. The noise you hear at start up for 5 seconds is the slack chain from the tensioner in the released position before it pumps up. The antibackflow filter from toyota helps, but will not totally solve this momentary rattle. I crank a few seconds and off and then start, no rattle. If you put plastic guides back in, believe me that you will be back in there. If you just get the steel guides only from D>O>A> racing, your done with the chain issue. One tip for you guys doing this project, if the gasket comes off with the cover on top side of cover, this is actually head gasket material and must be replaced when going back together as this spacing is critical because when you tighten the hidden bolt under the sprocket, you will break the cover if you neglect this gasket. Get a neww head gasket and trim the front piece you need and your set. On top use rtv ultra copper, good stuff. Guys, 85.00 is a lot of money for two steel guides, but believe me you only want to do this job once!!! Don't use Bosh plugs, these motors don't like them! Tim

Now THERE's something I haven't heard. I'm using a cheap NAPA oil filter right now. I suppose a good Toyota filter could potentially help. I've tried cranking/off thing as well. It works when the engine is cold, but I rarely get the noise then anyway. When the engine is hot, it fires too quick to do that.

Since I'm new to the Toyota truck scene, I researched and considered both the steel and plastic guides. Having put in OEM plastic guides, I know I'll probably have to get back in there at some point, and it'll likely be much sooner that I'd like. But I will say that I'd MUCH rather have the guides break as the chain, which is what is more likely to happen over the long haul with metal guides.
