OST-045: 5AGTE.... again ;)

As arrived. The head has been cleaned, but I don't know if it has also be pressure tested, so I'll be sending it out, along with all the associated bits to get cleaned and pressure checked before I start work.

The buckets and shims have seen better days... replacing them with good used units is far less costly then trying to salvage these

somewhere over 1.7 liters... final size depends on their overbore.

rusty shims - Now sure... the head came to me cleaned, but everythjing else just came in a box. The shims, and the buckets carry a moderate level of rust, so these items will be replaced.


work begins.... de-burring the casting......

Amazing work as always. How the heck do you get those shallow coolant passages around the chambers so clean?

One of the costs.... I have each head cleaned and pressure checked at a machine shop. In this case the head did come to me cleaned already, but I still had it checked for its pressure holding capability.
