needs a new engine?

Hello,

Generally speaking, depending on the issue with the old engine it can be more cost-effective to replace it. As it is more time-consuming to rebuild the engine.

What issue are you experiencing with the engine?

I have attached diagrams for engine replacement below your reference.

Please let me know if you have any questions.
Thank you.
