Learn Turkish: Motor bizi uğraştırmışken tamirhanede onu da yağlasınlar. - Since the engine gave us trouble, they should oil it too at the repair shop.

The suffix -ken normally means "while," but combining it with the past suffix -mış changes the flavor. The structure -mışken expresses "since this has already happened" or "taking the opportunity of this existing state." Because the engine already broke down and caused trouble, they are using the opportunity to get it oiled while it is at the shop.

What is the breakdown of the word uğraştırmışken?

It starts with the verb uğraşmak (to struggle or deal with). The causative suffix -tır makes it uğraştırmak (to make someone struggle / to cause trouble). Finally, we add -mış (perfective/past state) and -ken (while/since) to get uğraştırmışken (since it has caused trouble).

Is yağlasınlar a command? Why translate it as "they should oil"?

Yes, -sınlar is the third-person imperative (let them oil). In English, "let them oil it" can sound a bit formal or dramatic. When talking about getting a service done at a shop, translating the third-person imperative as "they should [do it]" or "have them [do it]" sounds much more natural.
