LIP SEAL FRONT COVER

'NEW Design that improves the original'

Our new 100/4 Lip Seal Cover is another product from Denis Welch Motorsport that has been taken back to the drawing board and improved in a new form.

For many years we have had to modify original front covers by sourcing or using customers existing parts. By cutting out the felt seal housing and using a special jig, weld in a new housing for a modern lip seal.

Following a complete redesign and using our new tooling based on the original works drawings, we are now making new cover with superb quality engineering. Our new Timing Cover is now better than the original, with the advantage of a seal that actually keeps the oil inside the engine, where it belongs!

We also have 100/4 Lip Seal Cover with a removable inspection plate to change the cam timing if used with our vernier cam sprocket.
