Rebuilt 3RZ-FE ANY IDEAS!!!

Had my original engine rebuilt after 240,000 miles cause I thought I actually broke one or both the chains. I ordered a master rebuild kit from LCE. I bought there forged Pistons that were 20 over original oem. Had block bored and head cleaned up, and crank was in good shape. The only thing I've changed myself was clutch, pressure plate, fly wheel and throw out bearing. I know it's easier to remove Trans to install engine but it honestly went right back in wasn't forced and everything lined right up. Had everything ready tonight to just cold start it and it will not budge. I got engine back in May and put it back together in July but all internal work was done at machine shop. All I put back on it was timing cover, brackets and intake and header. So if anyone has any idea why it won't turn over I would appreciate it.

 

Let's get this a little bump to help you out.

 

So????

 

Not enough info. Does it crank no start? Do you have spark? Do you have fuel? Or no crank at all?

 

Will not even turn over, I know that it did when I picked it up cause it was all in time at TDC before I put back together.

 

Can you crank it by hand? If so then it is probably the starter or a connection.

 

Did you check the crank to make sure it would turn after you installed each rod cap? You can Isreal them backwards and the motor won't turn over

 

i didnt install parts i had machine shop bore block 20. over install new pistons and bearings clean up head and check it out valves where in good shape as well as crank. hade all new gaskits and freeze plugs installed and the only way he could adjust valves is to turn crank i believe. everything i installed was on the outside of the engine. i did install timming cover and water pump myself. when i try to crank you can here starter engauge and i have tried turning byn hand with plugs out! its a no go so far! if you look at my pics you can see how i got engine back and what i installed.

 

If you can't turn the crank by hand to check that the valves are clear why would you ever attempt to start it with the starter? Lol. If you can't turn it by hand something is wrong. You should be able to turn it by hand even with spark plugs in. Time to start troubleshooting till you can turn it by hand. And don't try to use the starter till you know everything is clear and correct, if you haven't messed anything up yet you could if it turns over and something isn't ready.

 

STOP!!!!! DONT DO ANYTHING TO THE ENGINE it will void any warranty you have on it.


you just putting on the timing chain cover and water pump on wouldn't stop it from turning over but the oil pan "may" be hitting the crank stopping it from turning so pull off the oil pan and if that doesn't solve the problem then take the timing cover and water pump off and retry it, if its still locked up (which im sure it will be) then just bring it back to the shop who rebuilt it, let them figure out what they did wrong. they screwed something up if the engine is locked up and anything you do can possibly ruin it.

 

Like others have said, make sure the engine can actually turn. Using a long wrench on the crankshaft should tell you quickly. If it turns, read further.

With all that paint, your block ground may not be good. If the solenoid engages it is getting some current, but it may not be getting enough current to crank. Remove the block grounds, remove the paint underneath and reinstall.

 

one other thought is could the tranny be frozen and that is locking up the engine? is this an auto or manual?

 

If it was a manual the neural safety switch would prevent it from sending power to the starter unless clutch was in. Same with auto unless in park or neutral. Starter is getting power, it's something else.

 

Forget the starter. If you can't crank it by hand, you have found your starting point. Figure out why. Something is locked up. Something fell into the timing chain/cover? Engine and trans not properly mated?

 

Something to rule out. Lift the rear wheels off the ground and make sure you can spin the driveshaft with the trans in neutral. If not, figure out why not. Maybe try to spin the engine with the rear wheels off the ground.

 

I agree. It's something goofy and non typical. If your components you installed were wrong it would still turn by hand (socket on breaker bar or ratchet on crank bolt.). But if you can't turn by hand that's your starting point. Work backwards until you can turn it by hand or until you find the blockage.

 

And when you do finally get the thing unstuck, crank the engine over using the starter with the plugs out a few times to get oil pressure into the engine before combustion.

 

Just a wild thought here, since my one-and-only re-build experience was 20 years ago, on a 22R.

it sounds like the engine has sat, bone dry, for over 5 months without spinning. If that is the case, could the rings be partially 'frozen' to the cylinder walls? Was there any type of lube applied to rings and cylinders during the build?

 

what i said above was said before i realized i missed the part you said about the tranny and clutch, i now think this going to be where your problem area is so disconnect the tranny and clutch then remove plugs and try turning the crank with a big socket, I bet it turns over fine then.

my bet is the clutch didn't go in correctly and is binding up the engine

 

Ok yes engine had lube on it when it was assembled when I got home I added oil and zinc! I didn't turn engine by hand because machine shop set timing. Whether that was wrong or right I know now. As far as clutch goes I assembled it from Toyota specs as well as pinion bearing, fly wheel and pressure plate. As I said from beginning I did take my time but was in know rush to install. The insert to adjust clutch was installed while I torqued every nut in bolt and moved freely when complete. When engine was installed it was not forced and was not set in there and pulled into place by mounting bolts to Trans. Set in to place by hand and adjusted engine and Trans accordingly till it set into place slowly, like 4 hrs slowly. The only thing that I attached to engine and may of effected any internal parts was the timing cover but it was also installed to specs! Everything else was just brackets belts, intake , exhaust and believe that's it.
