2.5 yj engine

I am taking my 1992 yj to the shop for a new timing chain. I had my compression checked and I am running 150 in all cylinders. Not burning oil and engine runs strong other than the noisy chain. I was wondering while they have everything apart if I should have the oil pump and water pump changed also? or just save my money. water pump will be an extra 100.00 and oil pump 300.00?

Definitely do the water pump, hell it's off anyway, it'll cost more than $100 to do it later. (This is assuming of course, that you are having the work done, not doing it yourself, as it seems.)

The oil pump, I would personally do if your oil pressure hasn't been up to snuff. However, how does the oil pump mount on the 2.5s, is it inside the pan, therefore altogether separate from the timing chain change? If so, don't bother having it done, it won't save any money on labor. I am assuming this is the case, or else it wouldn't cost 300! Oil pumps are cheap, it is all labor.
