First off, i had a knocking in my engine come to find out it was all of my main bearings, and my rod bearings, got all sizes for each bearing set and made sure i have the perfect set for my engine, all piston rings were changed, head was surfaced, hot tanked, and checked for pressure. we have everything back together on th engine stand except we are stuck.

The FSM doesn't say enough about timing. In order to keep in time there has to be oil pressure, everything is set TDC and the engine is tight. BUT are we able to spin the crank without having the timing going out if we have the engine sealed up, and filled with oil?

This is the KA24DE. If anyone knows more about it please inform me. We are getting ready to drop the engine in the bay this weekend coming up, and we need to know weather or not we have to hold the tensioners while we crank the engine up the first time or weather it can jsut be cranked without losing timing. and having to be pulled apart again.

So, there isn't a way i can spin the cran a couple times on the stand to make sure everything is smooth without having the timing jump? does it have to be running? i'm just trying to be able to turn it over a few times on the stand to make sure nothing else comes up before i try to crank it for real.

spun and fail

we spun the engine 4 times and all 4 times it jumped timing on us. any other possibilities why?

get me nowhere

the last reply got me nowhere.. what i'm trying to ask.. i'll be a little more specific.

The tensioners are held by oil pressure. when you take apart those tensioners they lose the pressure they had in them. So, when i'm assembling the timing chain setup, and i have those installed.. they have not near enough pressure to keep the chain tight causing it to jump timing.. is there a certain way other than with a screwdriver to hold the chain in place when cranking it for the first time? i know once it's fired up once it will hold the oil pressure even when it's shut off. just the initial startup.

help please..
