I just rebuilt a lower end of a block for my 85 runner 22re. I reused the top end from my old engine. I replaced it because I had a bad piston slap. Now I have a loud rattle. I have 20psi for oil pressure at idle, all new parts in the lower end and they all meet clearances. I have oil getting to the top end. but I'm not sure if its enough. I removed the timing chain cover last night to make sure the plug was in, but with 20psi I think all the plugs are in. I'm going to drop the oil pan tonight to make sure the one below the sending unit is there. Any other suggestions of where to look for problems would be greatly appreciated. Oh yeah new timing chain, guides, and tension. I also adjusted valves 2 times. first time was to stock, then to a little tighter then stock.

 

22res are a noisy engine

 

true, lmao

are you sure it's a rattle?

if it sounds more like a clicking, the fuel injectors are notorious for being loud

 

I had a buddy say the piston pins might not be getting oil. Does anyone know how the piston pins get oil, or a diagram of the route the oil goes. I can track it up to the head then I'm lost.

 

I had a piston slap with the other lower end but not this noise. Its loud. My buddy said it might be the piston pins not getting oil, or the valve's taping the piston.

 

lol, I think you'd notice some other problems pretty immediately if the pistons were hitting the valves

and if the pins weren't getting oil, well then prepare for another tear-down to see why do you have enough oil in it?

 

is your balancer loose

 

The crank, rods, and bottom half of the pistons are all open to the oil pan. If you rebuilt the lower end you should know that already

Either way, make one thread and stick with it. I hate when people make two threads for the same problem, especially when they're brand new members because the forum rules should be fresh in your head.

 

I am new.. I posted on the 84/85 section and didn't see any one on in that section so I posted on the 86 and new section thinking that they were different. Now I know that its available to see under the new post section so It won’t happen again.As for the original question. I would assume that the piston pins are getting oil from what the crank splashes up?? Also the crank pulley was torqued down.

 

I put in almost 5 quarts. I think Monday will be a cylinder head removal day..... again....

are all your sockets accounted for?

could be a injector going bad, or a bent valve..................
