91 Prelude noise after timing belt replacement

So here is my first post and here is my first question, the other day i replaced my timing belt and water pump in my 91 with the B21A1 (shes done me good still not burning oil at 190k on the motor) and after starting it back up there was quiet the ruckus coming from the cylinder head area, at first i thought maybe the valves randomly need to be adjusted after not touching them? but as i went to go for a test drive it got vary loud, vary fast. so i rolled it back to my shop took it apart and checked everything, and it looked just fine all timing marks and everything, started it up and did the same thing with some scrapping/ rattle noise that got much louder after warming up. Any ideas anyone? Please and thankyou.

Re: 91 Prelude noise after timing belt replacement

Is the performance still as good as before? Gotta take that valve cover off. Hope there aren't any tools still in there. I also hope you didn't spin the crank once the belt was off. Stupid me did that once and bent some valves.

Re: 91 Prelude noise after timing belt replacement

u didn't turn the crank without the belt but it did slip a few teeth on turning it to TDC the first time no tools where in it the only other thing i could think of is if the tensioner wasn't set right but i don't think the belt was that sloppy.

Re: 91 Prelude noise after timing belt replacement

Did you remove any cam caps when you had it apart? They need to go back in the same spot they were in if you did remove them. The tensioner needs to be adjusted as specified in the service manual. If it's too tight you can get some strange noises, and if it's too loose the belt can slip.

Re: 91 Prelude noise after timing belt replacement

I did not set the tensioner to the 31 pounds but the belt and everything remained intact and aligned, I hear some people say that a cam can be 180 off but all valves are shut on no. 1 on TDC, sometimes I wonder why they had to switch to belts, what's the correct process of putting green on the belt?

Re: 91 Prelude noise after timing belt replacement

No, not the torque on the tensioner bolt, but the tension on the belt itself. There is a belt tensioning procedure. You need to follow it in order to set the belt tension correctly. Here is a link...

I don't understand what your asking in your last question... "what's the correct process of putting green on the belt?". Did you post that from a phone or something?

Re: 91 Prelude noise after timing belt replacement

Yes that was my phone sorry for dumb auto correction, but as far as if you put the belt over the crank pully and then over water pump and moving to intake and finishing it by exhaust cam? Or is there another way to put it on?

Re: 91 Prelude noise after timing belt replacement

The sequence in which you put the belt on each gear or pulley isn't important as long as you get it on correctly in the end. I've tried several different ways. The last time I installed a timing belt I finished with the tensioner. I started with the cams locked in place, then placed the belt over those, worked down to the crank gear, then over the water pump, and lastly over the tensioner. Seemed to work well. I'm not sure what sequence other people use. Like I mentioned before, be sure to use the belt tensioning procedure in the link I posted, after you get the belt on.

Re: 91 Prelude noise after timing belt replacement

Like Luzer said, The cam gears first Then the crank are done first and are most important.I've had belts that didn't quite line up on those two so I rotated the crank very slightly clockwise till they slipped over. Then I moved the crank counter clockwise back to TDC and everything was nice and tight. Don't really want any slack between those gears. Using drill bits to keep the cams from moving helps a lot too.
