Alright so this weekend i just threw in a brand new engine from Oregon engine builders. the "Superstock" 22re.

i ran it at around 2,000 rpm's for twenty minutes to break in the cam, changed the oil did all the proper break in stuff.
then i was revving the engine just a little bit and i noticed at about 5,000 rpms it sounded like the fan would rub for a quick minute. so i stopped and checked didn't find any evidence.
Then i drove the truck home about twenty minutes and upon getting almost home it started making the rubbing noise at idle and upon de-acceleration, at a steady throttle it doesn't make the noise noticably. at idle its really bad, it seems like its something thats catching maybe in the belts like one of the pulleys. i cut the a/c belt off thinking the pump was seized and that did nothing now i'm just minus a brand new belt.

the truck still runs great and has great power but does not sound good and its not just normal valve noise because it was purring like a kitten when first started.

please help!

Another ORE making noises? WHy does that no surprise me. Feel sorry for ya man.

Anyway, it's extremely hard to diagnose a noise without having some sort of video or audio, because anything would be a guess.

igottwonow

ya i'll try to put a video up tomorow but any idea's would be greatly appreciated. its wierd because it runs perfectly fine. it sounds like its outside of the engine, and at first guess i would say its the fan rubbing but its not cause i've checked that several times

Power steering? other than that, I would be taking shots in the dark and chasing a squirrel up a tree.

igottwonow

dont you think i would feel it in the steering wheel if it was the power steering?

oh wait, I think I kno what you might have done since at idle and decell noises is usually timing chain related or possibly a rod bearing.

Did you buy and entire engine or just a long block where you had to put the timing cover and stuff on? Because if you only got a short block, you might have put too long of a bolt in the middle of the cover (top oil pump bolt I believe) If a long bolt is used it will hit the timing chain. Since most of the slack in the chain is at idle and on decel it moves around in there enough to hit that long bolt.

Or one of your timing chain guides (most likely the drivers side) came loose.

igottwonow

it was a long block and yea i had to put the oil pump and timing cover on and all that stuff. i did have trouble getting the right bolts in the right place. which bolt do you think is wrong?

xxxtreme22r

the one in the middle. top oil pump bolt.

xxxtreme22r

This might explain it better. I explained it wrong too, the long bolt interferes with the tensioner not the chain hitting the bolt.

If it is too long and you replace it with a shorter one and you still have the noise it is still possible you damaged the tensioner and it's causing the chain to hit against the guide rails too much.

igottwonow

so if it did cause some damage what would i need to replace??

xxxtreme22r

timing chain tensioner at the very least. Guides if they got damaged by the chain. Highly doubt that though especially if you used a steel rail kit.

igottwonow

do you think i could get away with putting my old tensioner in there? the old engine only had 150,000 on it when the previous owner ran it out of oil and blew a rod.

xxxtreme22r

I wouldn't. Forgot to mention the timing cover gaskets as well and possibly the oil pump o-ring. Meaning might as well just pick up another timing chain set. www.engnbldr.com

igottwonow

so you dont think if i take that bolt out and put a shorter one in all will be well? i'm pretty confident that could be the problem

xxxtreme22r

50 50 I guess. Never done it, so can't say for sure, maybe you will get lucky.

igottwonow

thanks for the help man hope this goes well.

xxxtreme22r

good luck. also with the motor in general. Those ORE toyota motors do not have a good rep. Someone with those superstock motors just had a major issue with theirs. Does yours have the Kieth Black pistons and oversized valves in it?

igottwonow

i believe the pistons are regular, but it has oversized valves. i've been reading mixed opinions about their motors and most of them seem to be very good.

xxxtreme22r

2 or 3 complaints on here within a month or so, tells me something is up. I'd dig them up, but I am sure you can find them via the forums search. Most of the good reviews I have seen outside of here has been other make engines and not the Toyota ones.

Definately check the timing cover bolt first as XXX said. If that isn't your problem, you can pull the accessory belts to eliminate or isolate the problem from outside of the motor. If that doesn't narrow it down, you can pull a spark plug wire at a time to see if it is related to a particular cylinder.

Systematic checks are your friend.

And as XXX mentioned before, without a sound clip or video clip we are all just tossing pasta at the wall to see what sticks.
