Hi i have a 85 toyota 4x4 pickup with a new rebuilt 22-re. It has about 9,000 miles on it now and for about 3 months now i have had a kind of tapping or a really soft knock when i start my truck. it comes on after about a second or two of starting the truck. it is not a constant tap sound like the valve clearences, because i had it adjusted many times thinking that the noise was the valves. Although the vavles still can be heard i dont think the noise is coming from the valves. the sound goes away in a few seconds of starting the truck but if you gun the motor and when the motor reaches idle again it makes the noise for a few seconds. but as soon as the motor warms up maybe a minute or two the sound is completly gone and when you gun the motor and it comes back to idle the noise is also gone when the motor is warmed up.. it is only when the truck is first started that it makes this noise.

PLEASE SOMEONE HELP ME SOLVE THIS PROBLEM

THANX, LOPAKA

if you still running the single row chain and aftermarket oil filters there might be the problem, the t-chain tensioner might be bleeding down. Those take a bit too pump back up good and hard. Try a factory type oil filter with the check valve in it, toyota of course has one abd most of the time a a/c delco filter will too.

Yep, ratman nailed it. Timing chain tensioner. Mine did the exact same thing until I replaced it, hasn't done it since.

My truck does the same thing. So if I change the Tensioner? My motor has about 13k on it. So the tensioner applies tension from the oil pump. So oil press pushes it. Would a defective oil pump cause this. What causes tensioner to go out? Is there a beter brand of tensioner? Will not fixing it cause problems? You said a different oil filter? So the cheap ass frams are no good <IMG SRC="smilies/rolleyes.gif" border="0"> . will the dual row chain tensioner fix this problem. I have a dual setup just did not want to put it on this motor. Did not think I needed to.
Thanks
Steve

This really is a common problem. I see it at work once a month religously. The most common are the aftermarket tensioners bleeding down as stated above, OE crap still bleeds down, but not nearly as bad. Chances are your oil pump is fine, just an aftermarket T-chain kit.

The other concern you may have is piston slap. But if your engine has been rebuilt, chances are thats not it.

I think the black Fram filters have the check valve also.

Definately a common toy problem. All 3 22re's I've had did the same thing. My brand new 89 did it, and my 210,000 mile 87 does it.

EVERY filter has an anti-drainback check valve in it. The question is, does it work? The Frams *DON'T*. Fram filters are JUNK, do not use them. Believe me, I have cut several of them open and looked inside.

Use the Toyota OEM filters. They work great, and only cost $1-2 more than the crappy Frams.

Cool thanks for the info.
I will try a toy filter and see what happens.
I'm glad I did not take my motor apart. I thought I had a bearing going bad.

I have the same noise in my hybie with 11K on it. I use Napa (Wix) filters because of their quality. Anti-bleedback valves and better filtering then Frams.

do like everybody says use the toyota filter. Fram, penzoil and most all the other brands are made by the same company. I sure there is going to be somebody that disagrees with me but they are wrong. I personaly know the guy that is head over the paint shop at Fram and they make most all of the other filters there just painted a different color. <IMG SRC="smilies/usa.gif" border="0">
