That is really frustrating, and I would definitely contact the seller and ask for a partial refund. It is actually fraud.
If you decide to plow forward - I just did this (twice in the past two months) and I put together a
task list and part list for it - Maybe helpful to compare to yours, and I would love to see yours for comparison!
I am about to do it for a third time!
Yeah, it is really frustrating how shady people can be. The engine was bought through a seller on FB marketplace. I was close to making a post on FB in all of my local BMW communities, but I can not with out a doubt prove that he lied. I ended up just letting it go and taking this as a life lesson. I drove about 6 hour round trip. At the time it seemed like a great deal. I got the whole wire harness, complete engine, dme, ews, and key from the donor vehicle for $600. The seller had a video of the car running before the engine was pulled. Who knows... he may've been truthful about the miles, but the vin and car in the video suggest otherwise.
I dissembled the whole engine and brought the bottom end parts to a local machine shop to clean and inspect. The whole bottom end is in good shape. Piston bores are mildly out of round consistent with normal wear for an engine with high mileage. The machine shop told me a .50 over-bore would take car of that. The crank is near perfect.
I will be sending you the parts list via PM shortly. It is not quite complete because this engine is being built from the ground up, and I and I am sure there will be more unexpected parts / expenses that will come up.
Only performance mods currently:
- Forged CP-Carrillo Forged Piston Set 84.5mm (rings included and teflon coated skirt)
Factory specs / compression ratio 10.2:1
(Went with forged pistons because I the vendor that sells over-bored factory spec Mahle pistons told me they were back ordered indefinitely. I refuse to pay upwards of $300 for 1 BMW boxed piston. Plus the only over-bored OEM BMW piston I could find was just .25 and I wanted to go .50)
- Catless Headers
I am still on the fence about ZHP or shrick cams. Looks like I missed the boat on that purchase because I guess BMW used to sell the BMW ZHP cam kit for under $500 as pn. 11120429575 several years back.
