After the successful introduction of our Austin DS5 cylinder heads we have recently added new products to our DS5 inventory. These new parts are the perfect complement to the cylinder heads and provide a perfect opportunity to upgrade your engine if you're undertaking a rebuild. These parts are all exclusive to us and are not available anywhere else.

The Austin DS5 6 cylinder 4.0 Ltr engine, is very similar in design, to the 2.66 Ltr 4 cylinder Austin engine used in the Healey 100 and A90 Atlantic. The DS5 was used in the Jensen 541, 541R and 541S as well as in the early Jensen Interceptor.

STEEL CON ROD SET For steel crankshaft

These are H Beam style made to our drawings and specification by Britains leading manufacturer, with conventional fully floating little ends and can therefore only run with pistons that contain circlip grooves
(i.e. our pistons CENG409, CENG410, CENG411 and CENG409F).

These are considerably lighter and stronger than standard ones. They are only suitable for use with our steel crankshaft.

Please note that these are supplied as a set of 6.

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.
