I got my engine rebuilt by a local shop and i am having a lot of valve noise. Ive put 2000 on the engine now, the valves have quieted a little but they are still pretty loud. probably the loudest 22re ive ever heard. The shop claims its the nature of the beast, what do you guys think? any input would be appreciated

When the engine was rebuilt was the cam replaced? If it was, or not were the rockers and the rocker shafts inspected for wear? Just my 2 cents,I would replace the rockers,If a new cam was installed. The rockers need to be readjusted after the vehicle has been driven. A little bit of noise is ok,If the rockers are to tight, valve,rocker arm, cam and valve spring issues can occur. Its NOT normal,or the nature of the beast for LOUD rockers.

I brought the truck in and had them do the full job. It had a rod knock so they replaced the crank, bearings, pistons, reconditioned the head, new harmonic balancer, oil pump, etc. Rockers, valves, cam, piston rods are all stock. I paid 4gs and it makes some noise. He quoted me at 3200. It almost sounds like the timing chain rattles a little when i start it up. Im pissed  I could have had a built yota for that price. What do you guys think? oh and the builder said rockers, valves, and cam had no wear. engine was brought in with 223,000 on it |

Toyota parts are outrageous in price. Keep in mind a local shop can not compete with a major high volume re builder. The time to have taken action is when he gave you a price quote versus a aftermarket complete rebuilt. I would have come unglued, if I agreed and authorized the work for the price quote,and was presented a bill for EIGHT HOUNDED DOLLARS more. The very least he could have done is given you a courtesy call and have the extra work pre authorized. What type of pistons did the builder use? Did the wrist pins get replaced? Its possible the cam,rockers and shafts had no wear,but more than likely with 223k the engine is not a virgin,something what happens when most women get married,the guy is only getting the box the cherry came in. Just an opinion,the bill seems high if the cam,rockers and shafts were not replaced,but there again in all fairness, its easy for me to say that not knowing what all got done the hourly rate and the cost of outside work. I would take the vehicle and the invoice and sit down calmly, with the owner and express your concerns,try not to lock horns or get into a contest,which will only put him on the defensive side. Possibly make an appointment and have the rockers readjusted,which needs to be done anyway,also the head bolts need to be checked again. Not to pit one shop against another, you may want to go to another garage,dint go into any details on what was done to the engine, sometimes its good to get a second opinion. You may also want to have the computer checked to make sure nothing is stored in the memory. Something I like to do when I rebuild an engine is take a compression check before and after the engine is run so I have a good baseline for a future reference.

How long have you had the truck? Could be the cam and rockers were replaced before you bought it. Would be good to readjust them. Also re-torque the head bolts and change the oil after 500 miles.
As for the price, did you take the whole truck to him or did you pull the engine and take it to him?
If the whole truck then the price sounds ok. If brought him just the engine then just hearing the quote would have made me look elsewhere or spend a little extra for one from LC Engineering.

Yeah i just brought the whole truck into him since i didnt have the time to do it and just had to get it done asap. The engine seems to like 93 octane, it idles a lot smoother with it. When driving it is nice as hell but at idle and on a cold start up the valves will make some noise. Like i said before they have been getting quieter. I had been referred to this shop by a few other repair shops in the area. He had me bring it back in at 500 miles to have the timing checked and oil changed. The builder didn't re adjust the valves though, and im not sure if he re torqued the head bolts. If i am going to replace the cam and rockers what should i go with? I DD it but like to wheel as often as possible so its not really a street queen.

I'd say call the guy up and ask him if he re-torqued the head bolts and if he would be willing to recheck the valve clearance for you.
If the rockers aren't worn then there's not much use in replacing them. The cam you could replace with a stage 2 if you'd like, but not really necessary. A stage 2 cam will work better if you have a header.

I just replaced all the vacuum lines today, and it doesn't really run any different. Maybe a little smoother. So would loud rockers or rocker be a problem? or affect long term reliability? One thing about the engine that i noticed is that it sounds like the timing chain slaps or taps when i first start it up or if the rpm's drop real low, lower than idle. On start up the chain sounds like it makes contact with the metal guides lightly and only for a few seconds. This brings a lot of concern because it sounds just like the chain, and if its not the chain then i don't know WTF is ticking like that. The whole reason i had to get it rebuilt is because the oil pump pickup got clogged by the plastic guides that the chain ate threw. It doesn't make noise every time i start it, the inconsistency of the engine makes reliability questionable. Im about to snap  |

Long term loud rocker - rockers noise can cause premature wear and shorten the life of the cam and rockers. Its kind of a gray area when it comes to who absorbs the cost of the re-torque and adjusting the rockers, unless some type of agreement was made before the job was started. THE BOTTOM LINE - If I put out a large amount of CASH to have an engine rebuild I would want to protect my investment and have the head bolt re-torque done and the rockers readjusted regardless of who has to absorb the cost. By not having this done this could VOID the engine warranty. The chain issue should be taken up with the person who assembled the engine.Hard to say with 223k,ITS POSSIBLE you maybe dealing with a worn out distributor gear or distributor. As far as replacing the cam I would take DEADLY PEACE advice, its not necessary to replace the cam and rockers.
