Repairing corroded timing case covers - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

When I purchased my second motor to build the stroker motor into, we realised it had a few holes in the front timing case cover which had caused the engines demise. Instead of forking ludicrous amounts of money to Ford or buying a not so good Killkeny Castings copy, I set apart rebuilding the original.
The holes were obvious when held up to the light so I marked them with a Texta and went to my local Cylinder Head reconditioner (In this case - Fury at Lonsdale Cylinder Heads) and got them to glass bead it and weld it up. they have to start welding on the back of the timing case cover where there is more meat, and them weld the front (it doesn't need to look pretty cause you are going to grind it back anyway) I also had the water passages to the block build up to remove the small amount of corrosion there.
When you get your welded timing case cover back, the next step is to grind the weld down to the correct level (a small amount under the original level). I actually used a flap disc on a 5" grinder to do this but there are a fe different ways to do it. Now, you need to glass bead the faces to remove any impurities (and make the timing case cover shine again), then coat the face with Chesterton pump repair liquid. There are a few different types but you are after the thin brushable one. The liquid is like clag and needs to be worked into the holes, but care needs to be taken not to make it too thick or it will interfere with the water pump impellor. Let the coating dry and check your clearances with the waterpump (using no gasket). I used some plasticene to check but so long as it does not rub you should be pretty safe.
All you need to do now is clearcoat the aluminium and return your reconditioned timing case cover to the motor.
Happy Playing
