Timing chain

[AndrewT]

Looking to convert my chain to the mini type with a tensioner will I be ok to fit the mini timing chain cover even although it has the canister breather on the front?

The timing chain cover with the canister on the front will fit but clearance between fan and canister is tight.
You can add to the clearance by fitting a spacer between the fan and pulley. They can be obtained in a couple of thicknesses.

The timing chain cover in the link below is suitable for fan clearance:-

The cover in your link is the same as I got by the looks

[philthehill]

The timing chin cover in my link above (Pt No: LJR10168) has the flattened front face to the separator canister so giving additional clearance.
The timing chain cover in your photo is Pt No: CAM4868 with the round canister and is the type fitted to the Marina etc.
The timing chain cover can be used with the duplex set up and tensioner but the concave dimple and timing sensor mounting bracket has to be removed before fitting as per the photo below.

Ah I see so knock the dimple out from inside and remove the sensor part from the outside and that's it?

[philthehill]

That's it - but you must check the clearance between the oil deflector ring (fitted to the inside of the timing cover and is around the canister opening) and the timing gear when using the duplex chain.

I got you if that's a touching or Abit to close do you have any tips for increasing the gap between or is it just a case of trimming with say a air hand belt sander or something to that effect

[philthehill]

I have seen the clearance between the oil deflector and the timing gear increased by bending/flattening back the deflector to it being reduced is depth by grinding.
No doubt you will work something out but what ever you do make sure that you plug the hole into the breather canister so as to stop any filings/metal/crud getting into the canister and later falling back into the engine and doing damage.
Make sure that you clean out the filter/gauze inside the separator canister to ensure that there is adequate air flow through the gauze.
The gauze can become clogged and moisture trapped can reduce the gauze to a solid mass.
Below is the remains of a gauze I removed from a canister - not a pretty sight.
The pieces of wire are the remains of the spring clips that hold the gauze in place.
If the gauze is bad clean it all out and fill the void with one or more stainless pan scrubs.

[AndrewT]

This any better phill?

[philthehill]

Well done.
Removing the timing sensor dimple and bracket allows the use of a duplex chain.
But do not forget to check the clearance between the oil deflector and the camshaft timing gear and adjust as necessary.

Will do! Thinking more to just trim the deflector rather than bending it so it still has a use of some sort
