Is the crankshaft oil seal fitting tool needed or can you DIY one? got the engine out and in bits to replace it but didnt know if it was worth spending £25 or so on a tool I will probably only use once or if a simialr tool can be made from old tubes.
Also when exposing the old oil seal it has silcon sealant smeared around it... Im guessing someone tried to botch the leak up at some point or are you suposed to put some sealant on as well?
Thanks
