I hate working on cars, tractors and other greasy things. But, I do all the work on any of mine that need anything for just this reason.
At times I have hired a tradesman to do things, I always tell them to do the job as if they were doing for themselves, and if this involves extra cost, tell me because I will probably want to buy it. So, then after the job is long done and I have to go and repair it again, I still find out that this guy cheaped on a part and that is why it needs attention -
AGAIN!!
