Default Timing Chain Plug

Had some time today so I whipped up a new aluminium timing chain plug from aluminium. Way cheaper than the $60 odd AUD the guy on eBay wanted

It's 2 pieces and when tightened provides 20% crush on the O ring expanding the O ring enough to prevent the plug falling out. I added an M3 bolt through the back to prevent it from falling apart if the front bolt is removed, in other words the back is retained and can not fall down inside the timing chain cover.

Looking GOOD.

$60, damn, that should include the timing cover, OR travel to you and install.

Hi Daim,

If you wanted one I could make a few more, they would be $20AUD plus postage. If anyone wants one just leave a message on this thread.

I don't have this engine and won't need it but purely curious being a mechanic nut myself, you mentioned a safety retaining screw in the back to hold the rear disc from falling out if the front hex drawing screw were to be un-threaded too far. Great idea..but how do you prevent the rear screw itself from backing out and falling in to the engine. I'm sure you have thought of that and is probably as simple as a thread lock compound on it when you first screw it in as it never needs to be touched.
Not knocking it, just a little detail I observed. It's a great little mod.

I would take a guess...

Shorter thread in the front rear part and then the screw threaded in and tightend with loctite... Shouldn't fall out at all then...

Yep Loctite the retaining screw in. The front screw does not need it because the O ring provides tension on the thread.

Received my timing plug yesterday. What shall I say, it is an awesome piece of kit! Thanks Warren!

You ought to start your own "product line". Rear half moons made of aluminium. This that and the other! I'd buy the lot!
