Hey Ive just finish doing a head gasket change. Went to start it and it doesn't want to fire. There is spark, and the engine turns. NRMA guy came out and check the compression. Only 50psi. I did remove the timing cover so i can replace the timing guides when replacing the head gasket.
I notice after a full rotation of the timing chain by hand, the timing marks where out. But i didnt pay much attention. I remember that on the chain that the two yellow links where on the right hand side. The top of the head was aligned in the middle of the two yellow links on the chain. As i rotated the engine, TDC mark and the two yellow links went lined up as before i rotated it. Im pretty sure it is the timing which is out. What is the best way to redo the timing with the marks all lined up? By the way, i got an el i6. Cheers Adam

Bump any one. I'm going to fix it tomorrow. So any advice would be good.

Engine tdc on compression stroke...
The cam gear should line up with top of block.. The dissy drive should be on #1 plug location too if required...

The mark on the timing sproket is actually meant to be about 3mm above the top of the head when on TDC. It is close to being in line with the top of the head, but not quite when you bend down and take a good look.

actually anywhere between 3 mm and level is fine.

rip the timeing cover off and line it all up again

Im not ripping it off again. Any other way? Can i just move the cam a little?

you could but are the marks on the crank and the other wheel lined up?

nup. I was just thinking of re positioning the cam so i dont need to redo the chain.
The only way to put the chain marks back in position is to take the timing cover out. If i put the piston TDC and make sure the cam is straight ( none of the valve is open) and the dizzy is firing on number one. that should work. Hopefully. Can anyone agree with me with this solution?

If you have the crank lined up at TDC and on firing stroke (with rotor pointing to No.1) and chain tensioner off. Mark the chain for reference.
Then you will have to unbolt the timing gear from the cam and move it to some other tooth location on the chain, such that when the gear is bolted back to the cam and the cam suitably rotated, the mark will line up with the head. Disregarding any marks on the chain other than the ones you put there.

Ive got compression in cyc. 1,5,6 (very good). cyc 2 has no compression, cyc 3 has about 60 psi and i cant remember number 4 ( think around 140psi)
What could be causing this problem?

Ok ive found the problem why i wasnt getting compression in the other cylinders because the tappets (not sure if thats what there called) in the rocker where stuck open and where holding the valves open.
I bought a second hand rockers. the compression is between 200-210psi. Is that too much compression? When i start the car, it doesnt want to run at idle. But if i accelerate the engine around 1000rpm, it runs fine. Also i broke a sensor which is near the coil. It plugs into the block. What sensor is that and will the stop the car from idling? Im going to check the timing and hopfully that will help the idle. The car is a el running on gas. The battery has be taken out so the ecu needs to learn everything again. So im not sure if the ecu is causing the car not to idle or just timing. If someone can advise me on what to do. Also answer the questions above will help me. Cheers Adam.

sensor sounds like Oil pressure sensor i think....
also have you checked your timing with a timing light ? |
