Have a 307, 2004 petrol 2litre manual car.

This engine has the crank locked at the flywheel, not at the front of the engine and the cam wheels pinned.
Key-less crank sprocket.
I did a 206 GTI last week and presumed that the crank gear would be keyed, similar system ..i undid the crank bolt to find the gear loose, no keyway and the later type hub/balancer.
However the car was in gear and the brake rotors pinned.

The bolt came undone fairly easily and i don't think i damaged the valves.

i can't find the hole in the flywheel when looking through the hole?

Someone mentioned the crank isn't set at TDC on these engines?

I set it at TDC and there is valve interference. As i said i wasn't heavy handed and never forced the things getting the bolt undone.

Any ideas

Reliable 406,

i am in rural Australia, about 300klms from nearest French garage so there is no one to ask, a mechanic told me it is the same system as Renault, it isn't..

The tool kit should arrive today in mail, will go into the village and check.

Once i set the crank position with the tool and pin the cam wheels we will see if the engine rotates without problem.

*Is there anything i should watch for in fixing the situation?

Thank you.

P307 belt troubles.

I can see clearly the hole above the driveshaft and the pin hole which is at the #3 TDC.
This is in contradiction to what you say that the pin hole is at piston half-way down.
I have locked the exhaust cam .
The inlet cam wheel needs to go clockwise slightly to be pinned.

Your instructions,

"The crank is NOT set at top dead centre when pinned the pistons are half way down the bore when pinned adding to the potential.."

*Do i set the crank with all the pistons at the same level?

**Now i wonder if it is an earlier engine fitted with a later crank hub?

Am i doing something wrong?

ALL these EW engines are timed the same way regardless of age fitment floating or non floating crank it is not 3 degrees before or after TDC it is way more than that you may be in the wrong hole in the crank im sure i posted pics on 1 of the threads of an engine with crank timed showing pistons in bore.

I dont have a stripped engine here to take another pic sorry.

P 307 cam timing?

Hi,

after reading the various posts i understand better the situation.
Yes there were two holes in the crank, i used the correct one and the car runs.

*The hole that i used doesn't quite match up to the pistons all being level?
I know this because i put rods in cylinders #4 & 3 to get equal heights.
Is this correct?

Cas.

Reliable,

many thanks for confirmation.

in the event of the timing being out one tooth what you notice?
Would the engine sound different?

Any signs.

Going to re-check later today.
Sounds slightly different at exhaust, although it idles and runs perfectly?
I will fix a slight leak in the exhaust and then see, might be the problem.

Otherwise all good.
