TIMING COVER OIL SEAL RENEWAL

Things to look out for ;

Do not lie under the radiator when removing ; ............You might get a face full of coolant !!!

Remove the water pump ; ........... Make sure that you have a couple of spare water pump gaskets .

Remove the timing cover pulley ; ...... After removing the timing cover pulley check for grooving at the witness marks where the oil seal has been sitting on.

If worn then , even if you fit a new oil seal , there is a high chance that it will leak again .

If bad , this can be helped / sorted by fitting a very expensive sleeve as per ;

After removing the timing cover it would probably be wise to check and /or replace the timing chain / tensioner if badly worn .

The following Photos / words were submitted to me by Pavel Konvalinka from Prague in the Czech Republic ;

The oil seal should be slightly oiled by WD 40 spray or engine oil.

I pressed it from the timing cover outer side to inner side, because it was easier to start from that side.

It goes very fast and exactly parallel.

Before re-assembly make sure that all the old gasket and any rubbish sealant that previous owners have used is completely removed from the timing cover and water pump sealing faces .

Personally , I have never used anything other than High Melting Point grease on both sides of the gaskets to seal .

Fit the bolts through the timing cover and and fit the gasket .

Bring the cover up to the block from the bottom left side as the tensioner has to rest against the chain and you will feel a wee bit of resistance as you line up the bolts .

At this point do not tighten the bolts up fully so that the timing cover can be moved in all directions very slightly

Fit the pulley and check the seal is even all round then tighten up the timing cover bolts .

Fit the water pump and all the rest of the bits you have taken off and hopefully you will have a non slippy engine bay

TIMING CHAIN / TIMING CHAIN TENSIONER DAMAGE

I had an engine which had become very clattery so I began to strip it down and started at the timing cover ; The following is what I found inside the Timing Cover .

THE GOOD SPROCKETS ON THE RIGHT ARE JUST FOR COMPARISON .
