1jz will not crank, possibly seized Sat, 12 November 2005 11:11 Go to previous message
Hi,
I have come across an interesting problem. I am pretty much at the end of a custom (non-toyota) engine (1jz-gte) transplant and aimed to get the engine running this weekend.

This afternoon, I was trying to crank the engine over, the starter motor sounded a bit weak - it had a click fest, and did not really crank the engine (just a tiny bit). At first I thought it was a dead battery. Replaced it from another car confirmed to work. Same thing. Then I thought the starter motor (2jz/w58) was dodgy... tried the one supplied with the engine (1jz jzx81? auto)... same thing basically.

Some observations and things done that may or may not be relevent:
- clutch disengages when pedal is pressed.
- engine cranks when putting gearbox into 5th and pushing car.
(albeit some weird pair of noises (low pitch hinge-squeeking type of noise) at particular position? clutch slipping??)
- starter motors work outside of the car. although this may mean nothing.
- using jump start cables to connect battery to terminals inside of car. (dodgy connections?)
- timing belt was replaced a few months back. pretty sure it's right... but I could be wrong.
- clutch disc (+ other consumable items eg: bearings) was replaced
- flywheel face was machined, not pressure plate side.
- allen key head type (12.8) bolts was used for pressure plate
- corolla clutch bolts (11.9) were used for flywheel.

I did not verify if the engine could crank 1 revolution while it was outside the car.
I have not yet verified if the engine can crank (or if there is any difference) with no spark plugs installed.

Any pointers or questions? I am pretty much stumped :(

Thanks.

-BK.
