Sprint crank oil seal

[Stuart Wilson]

I've a sprint engine fitted in my TR7. The front of the engine has always had a little mist of oil on it but noticed recently it's getting worse so thinking time to do the front crank oil seal.

Is there anything I need to be aware of when changing this or is it just a simple one out one in sort of job?

You'll have to take off the timing gear, so a timely operation would be inspect and consider replacement. However, make yourself aware of the issues surrounding timing tensioner quality, along with curved guides being seemingly unavailable at the moment. I think Robsport do a kit with curved guides though .

Make sure the seal running surfaces are not scored . you may need to replace this as well as the seal.

No need to remove the timing cover or timing gear when you want to replace the front crank seal:

As always very good helpful advice, I shall get an oil seal ordered up and get it done at some point over the next few weeks

Silly me, I was thinking bottom pulley, but visualising bottom sprocket; Of course you don't need to remove the timing gear!
