Crankshaft locking hole location?

[discv]

Peugeot 207 1.4 8v petrol TU3A - VF3**************[VIN obfuscated, can be read by forum staff]

Help please- I just cannot for the life of me find the flywheel locking pin hole.

Here you go - the relevant part from the procedure.

Turn the engine clockwise (normal direction of rotation) by means of the crankshaft pulley bolt to bring the camshaft pulley (8) pinning point (at "a") close to the cylinder head pinning point (at "b").

Peg the engine flywheel using the pin [2].

Thanks Marc. I was searching in completely the wrong place underneath!

I actually posted that a few minutes after you posted - as I thought you were in the middle of a job and having a panic attack!

[discv]

The panic attack is kicking in now! I started the job by posting a photo of the 'mayo' problem I am addressing. It looked like a silly question and, deservedly, got no replies!
What I was looking for was if there was any common factor in this PSA engine problem.
Now having lifted the head, the gasket is a bit shabby but no screaming signs.
But one liner is very slightly skewed. I will post a photo in a while.

[discv]

Attached shots of skewed liners. Back in the day I would have dropped the sump etc ect. This is no longer an option- my daughter is doing the lifting while I direct from a seated position!
A big end removal and refit would be a bit much for her.
What to do now?

Hi. Apologies for resurrecting this zombie thread but it is the only reference on the internet I can find which has the info I want. I thought of starting a new thread for this query but figured it might be better to keep all the info on the subject in one thread for others' convenience.

I have a 206 1.4i (TU3JP) just like the one on the thread. Like Discv I am refitting the cylinder head after a gasket failure. It's after 145k miles so it isn't unexpected as it is about the only real weakness of this engine as far as I can see. I have been searching for anything which will show the location of the crankshaft locking pin hole and, whaddya know, here it is - at last! I have Peugeot Service Box and I couldn't get a clear picture from that. Well Discv has sorted that problem now.

The Peugeot "special locking tool" for the crankshaft is just a piece of round bar, bent to be able to get behind the oil filter and turn at 90deg into the hole. The camshaft locking tool seems to be 10mm, an M8 screw fits and does the job. An Allen or Torx key would do the job I suspect if I knew the size. I'm going to try to manoeuvre an Allen key into position but I would like to know what the diameter of that bar is on the correct tool. I could use drill bits to probe and see which is the best fit as they are accurately sized. However, the hole is too awkward to get a drill bit into it as a bit of that size would be too long to turn the angle near the filter. Can anyone out there offer the correct size, maybe from someone who actually has the locking kit available?

[Bordonbert]

I've done a bit of simple diagnostic work now and it looks as though the crankshaft hole is 6mm. A T30 Torx key fits in there a little loosely and that mics up at 5.68mm diameter. It needs to be inserted about 27mm into the hole and there is only about 40mm of access due to the oil filter and an engine rib.

For anyone wanting to make a locking tool for themselves I would use 6mm rod or perhaps a thinner rod for ease of bending with a 6mm sleeve on the lower section which is inserted. Bend it at a tight 90deg at 40mm from the end to bring it up 100mm vertically to clear the filter. Then bend it at up to 90deg towards the front to bring it away from the exhaust manifold. The picture shows that shape clearly. In my case the dipstick tube was bracketed to the block across there and was in the way so I have to work around that too but it is pretty straightforward for anyone at all handy.

In fact, for someone who is familiar with what we are working with and with a 38 tooth camshaft sprocket and a 19 tooth crankshaft sprocket it is difficult to get this wrong. You have a lot of play before you can be a whole tooth out on either sprocket. It's 9.5deg for the cam and 19deg for the crank between teeth. If you have the cam sprocket in view and the crank sprocket Tipexed to TDC, any discrepancy with that amount of play should be obvious to the naked eye. That said, the locking tools take away the "2am, eyes closing, mind drifting" scenario we get into occasionally. so can't hurt at all.
