General Meaning question: "inframe head"

[e42b]

Hi all,

alright, my mother tongue is German but my English is quite usable as i experienced over the years.
A friend of mine asked some translating engines to put the sentence "Great video as usual! Need some info off topic. If one does an inframe head and all do we need to go with overhead intervals as if engine is new?" into sense. They did not succeed but put total nonsense out instead.
What i got is that "If one does" means to recondition a part, and a "head" means a cylinder head.
What i don't know is the meaning of "inframe head".
An inframe working on is to put the machinery into a frame, that works as a testing facility. That's bloody it.

Does anyone pull any workable sense out of this sentence?

Thank you very much in advance.
Cheers
Elmar

I don't understand what they are trying to say, but my guess for 'inframe head' is that they are proposing to remove the cylinder head with the engine in the vehicle.

Most cylinder heads can be removed with the engine in the vehicle, but occasionally in some it may be necessary to remove the engine from the car.
