Front cover oil leak

Since I rebuilt the engine I've had an small oil leak somewhere around the front cover. It has not been any problems at all with normal street usage, but after a track day the the leaked oil makes a mess from the front cover and rearwards.

I had my dampers dismounted for another reason and now I had plenty of space in front of the engine. I removed the starter motor to be able to lock the flywheel with a chisel when removing and tightening the front pulley bolt.

I used CRC Gasket Remover to  remove the old sealant a bit easier.


New pulley bolt, new front mainshaft seal, new diamond washer, new bead of RTV sealant.

Because the front pulley was removed I had to set the cam timing again. Easy when you've done it before.

Dry sump blanking cap

New vs old

On the EU4 CSR 200 there is a hose between the external dry sump oil tank and the dry sump. When I rebuilt my engine I changed to an open oil system, and that hose was no longer needed and the unused hole in the sump needed to be blanked.

The problem is that it uses a very unconventional thread: MF22x2.0

After many failed attempts to find a fitting blanking cap I finally went directly to the source - Titan Motorsport, and of course they had one.

So for the record, the part number is:  A1016510200A3


For both theirs and my convenience I ordered it from Burton, who in turn got it from Titan.
